I am getting a "java.io.IOException: Server returned HTTP response code: 403 "

**willemjar** · June 12th, 2013, 06:38 AM

Hello all

I am not new to Java but I am new to this forum.
I am struggling over an applet that should read a file dir of
the host (not the client).
Being a good boy I constantly use, of course, a code based path....

I am getting a "java.io.IOException: Server returned HTTP response code: 403 "
and I do know what it means.

here is the method in question (I get until the print "connection is open" than the method

jumps to the catch statement):

private void doListofImagefiles(String foldername)  { //URL
        //checking and storing the present files of the folder
 
        URL url = null;
        java.net.URLConnection con = null;
        try {
              url = new URL(getCodeBase(), "slideshowImages" +
                    File.separator + foldername);
              System.out.println(" Do the image file list of " + foldername);
              System.out.println(" the file list path is: " + url);
 
        }
        catch (MalformedURLException ex) {
              Logger.getLogger(SlideshowApplet.class.getName()).log(Level.SEVERE, null, ex);
              System.out.println(" can't find the file path: " + url);
        }
 
        if ( url != null)  {
            try {
                con = url.openConnection();
             //   HttpURLConnection conh = (HttpURLConnection) url.openConnection();
 
 
 
              //  con.connect();
 
                System.out.println(" connection is open for the file list " + con);
 
                //the array list will contain the correct files
                imagefiles = new ArrayList();
                java.io.BufferedReader in = new java.io.BufferedReader(new
                        java.io.InputStreamReader(con.getInputStream()));
 
           //    InputStream in = con.getInputStream();
 
                String line;
                System.out.println(" BufferedReader is initiated");
                int i = 0;
                for (; (line = in.readLine()) != null;) {
                    System.out.print(i + "  > " + line);
                    //adding the checked correct image files
                    if (checkImageType(line)) {
                        imagefiles.add(line);
                    }
                    i++;
                }
                maximages = imagefiles.size();
                System.out.println(" the arraylist length is: " + maximages);
            } catch (IOException ex) {
                System.out.println("  can't download the file list ");
                Logger.getLogger(SlideshowApplet.class.getName()).log(Level.SEVERE, null, ex);
                System.out.println("  end of error message ");
            }
        }
        else
        System.out.println(" no fillename array is setup: " + url);
    }

How can I improve to code so it'll work
and where lays the problem:

a) my programming skills;
b) java site (sand box stuff)
c) host for not having Java installed or not wanting to grant permissions

thanks pls any help is welcome....

You are trying to list the files in a server directory? Best guess is that the server does not want to provide you with that access. HTTP 403 is an access denied error. The server received and understood your request, but refused to fulfill it. This is not uncommon.

Are you attempting to access a server which you have ftp access to? If so, my suggestion would be to try a server-side approach. For example, to solve this problem myself, I have:
1. Created a simple php file that can read the files (I can help you with this step, it is very simple)
2. Made the php file output the data somehow (I use xml, but you can probably just use plain text)
3. Made my java program query the php file to get the result
4. Parsed the php response in my java program

This is all very simple to do, and may solve your server issues (unless your host refuses php access like this, which it probably does not).
There are other ways to go about doing this, but I have found the above to be by far the easiest, most reliable, and fastest.

**willemjar** · June 12th, 2013, 10:19 AM

auss that is very interesting what you are saying! A friend yesterday talked about php (which I do not know) and said that it is not difficult to learn.
For the moment I am learning Java collections (reading the javacore II book). I will turn very soon (next chapter) to interneting.
I suspected that the problems lays with the server (Spanish based) and when I asked they answered this:

Good morning Willem,
You can clearly see that this applet need JAVA to work correctly. Our servers don’t work with JAVA.
In this case, the only service that we can offer you is a non managed service as a VPS or a dedicated server.
Thank you and have a nice day.

So it is not true that "Java has to be installed" in order to make my applet run, right? (since it runs on the client's comp)
He just does not want to grant that permission, right?
I will eventually (when reading the next javacore chapter) get into php as well (have downloaded a manual yesterday).
But for the moment it is all pretty overwelming....

Auss is there another way to make that code run? Or might that mean to much trouble?
The method jumps to the catch after I opened the con connection.
The host does not like me doing:

java.io.BufferedReader in = new java.io.BufferedReader(new
java.io.InputStreamReader(con.getInputStream()));

what alternative is there for this.....
I eventually will get to your four points, because I do not know if applets have a clear future
(they do not run on my family's Ipad after Steve Jobs "prophetic" words about Java)

thanks Auss

ps "Are you attempting to access a server which you have ftp access to? " yes!

**aussiemcgr** · June 12th, 2013, 11:26 AM

It might be a restricted file type, so .jar files or whatever will not be allowed to upload. Many free hosts disallow executable languages on their servers for several reasons. If you would like, I can provide you with a free host which allows java. For "small" websites, they don't force ads on your pages, but for "big" websites they put a few. Unfortunately, those ads are those crappy javascript ads which look like viruses, so it might scare some people off.

The php file I use to get a list of files is this (I am probably using some outdated libraries, but I am a php noob):

<?php 
	header('Content-type: text/xml');
 
    /* create a dom document with encoding utf8 */
    $domtree = new DOMDocument('1.0', 'UTF-8');
 
	/* Root */
	$xmlRoot = $domtree->createElement("list");
	$xmlRoot = $domtree->appendChild($xmlRoot);
 
	$conn = ftp_connect("yourhost") or die("Could not connect");
	ftp_login($conn,"yourLogIn","yourPassword");
	$array = ftp_nlist($conn,"theFolderToLookIn");
	foreach($array as $value) {
		if(strpos($value,".anExtension")) { //I am filtering by extension, you don't have to
			$xmlRoot->appendChild($domtree->createElement('file',$value));
		}
	}
	ftp_close($conn);
 
	/* get the xml printed */
    echo $domtree->saveXML();
?>

That just builds a basic XML output of the files in the directory, which I can then call directly from java and parse with the following code (it uses a class called XMLUtilities which I made to help myself parse XML documents more easily, you can ignore references to that class and just use the standard java API):

public static List<String> getFileList() throws Exception {
		String query = HOST_URL+"listFiles.php";
		List<String> ret = new ArrayList<String>();
		try {
			URL url = new URL(query);
			logger.info("Querying: "+url.getPath());
			Document document = XMLUtilities.loadXMLFromURL(url); //Loads the XML file into a Document from the URL
			Element element = XMLUtilities.getChildElement(document, "list"); //Gets the root node
			NodeList list = element.getElementsByTagName("file"); //Gets a list of all the file nodes
			for(int i=0;i<list.getLength();i++) {
				String file = list.item(i).getTextContent(); //Gets the file name
				if(file.contains(".")) {
					file = file.substring(0,file.indexOf(".")); //Gets rid of the extensions for my own reasons
				}
				ret.add(file); //Adds the file name to my list
			}
		} catch(SAXParseException ex) {
			throw new Exception("Prolog Exception"); //This is thrown when the server has too many connections
		} catch(Exception ex) {
			ex.printStackTrace();
		}
		return ret;
	}

If you wanted to try to do it in only java, you would have to make an FTP connection and read the directory itself. That will return some crazy weird file that contains a list of the file names, as well as a bunch of other html stuff and other crap. This can be a real pain to do. It will also require you to add a digital signature to your jar. But if your server chooses to, they can probably not let you connect this way.

--- Update ---

Also, applets, for the most part, are already being fazed out. But Jobs was still wrong that Java has no place. Most companies are moving to html5 and other web-specific languages to build the user interfaces, and only using java as the back-end system. This works quite well because java interacts with javascript, jsp, json, xml, php, ect. relatively easily.

**willemjar** · June 12th, 2013, 11:55 AM

Auss many thanks I'll look into it all!
"If you would like, I can provide you with a free host which allows java."
I might be very interested since I am still trying out the site and need some space to do so.
I worked so hard on that applet (still no easy job for me) and like to it see at work.
(there are actually several in different sizes with and without text buttons etc.)
That space might be even a solution for the future since the web only contains only 25 mb.
so let me know where to upload, please

salud willem

ps the ftp version of java I will get into when studying my next chapter: internet!

**aussiemcgr** · June 12th, 2013, 12:10 PM

I use Free Web Hosting Area - PHP 5.4, MySQL 5.5, FTP, Autoinstaller
They have a handful of domains you can use. I use orgfree. There does seem to be the occasional connectivity issue lately (says there are too many people connecting to the server), but it is usually pretty good. They have free database support, but the database can only be connected to via localhost (meaning, from the server-side), so it can be a bit of pain to use.
I would HIGHLY suggest using an FTP program (such as FileZilla) instead of their provided FTP client. Their FTP client seems to like to slam the door in your face.

**willemjar** · June 12th, 2013, 12:15 PM

I used fetch for a while
Thanks for those links!
The applet will run without problem, I hope?

**aussiemcgr** · June 12th, 2013, 12:24 PM

The servers should fully support java. The only problem I've had with my applet is when the server is down, but that is to be expected I suppose.
With that being said, it does NOT seem to be an application server. For now, you probably don't care, but when you start reading about servlets, jsp, and other server-side java-related programming, just know that you will not be able to run that on the server. Server-side requires an application server, which is a server that has Tomcat, GlassFish, ect. installed.
You'd be hard pressed to find an application host for free. I haven't been able to find one, so I do all my server-side programming with php scripts.
Java Applets do NOT require an application server, since it is running on the client (instead of the server), so you should be fine for now.

**willemjar** · June 12th, 2013, 02:46 PM

Great I haven't a domain name yet. I suppose one gets a (small) space to upload under some:
www.sdfdfs/sfdsf/sdfds/sfds/myspace
I'll put the index etc. first in a folder to try out things in a private manner,
before publishing the site

Thanks again for all your good and relevant info, Auss

--- Update ---

You need to have a domain name to start the site
(I'd like to get that later after the site is running correctly)?

**willemjar** · June 15th, 2013, 05:34 AM

auss got the site (thanks again) you can reach it here:

mywebpage

but run into the same trouble (I believe)? Here is the error code:

Auss I have it working (reading the folder directory)
but indeed it is dishing up a lot of crap I do not understand!
Look here the first part comes from the file version of the website which is correct.
The second listing comes from the website....
So I have to look into this what else it is printing....

the arraylist length is: 0

--- Update ---

It is obvious that the second listing is not finding images
and is not filling the arraylist: so I end up empty handed again
But I am making progress, right?

The server will refuse directly reading a folder from an exterior program (such as an applet) unless you code in the connection specifications and sign the jar (you have to do both).

To code in connection specifications do the following:

private static final String FTP_PASSWORD = ""; //Put your FTP password here
private static final String WEBSITE_FTP = "ftp://willemii.orgfree.com:FTP_PASSWORD@willemii.orgfree.com";
private List<String> fileList = new ArrayList<String>();
 
private boolean readFileList() {
	BufferedReader in = null;
	try{
		URL url = new URL(WEBSITE_FTP+"/FOLDER_TO_READ");
		URLConnection aurlconn = url.openConnection();
		in = new BufferedReader(new InputStreamReader(aurlconn.getInputStream()));
		String line = in.readLine();
		while(line!=null) {
			String res = parseLine(line);
			if(res!=null)
			{	
				fileList.add(res.trim());
			}
			line = in.readLine();
		}
		in.close();
		return true;
	}catch(Exception ex){ex.printStackTrace();}
	return false;
}
 
private String parseLine(String line) {
	//Whatever code you figured out to parse the line of the file to find the individual files
}

You then need to sign your applet. Without signing your applet, the connection will be refused.

You are making progress. The problem now is that you have to use a rather creative algorithm for determining the file names.
Based on the above input, here is the algorithm I would suggest to you:
1. You should search each line for the sequence: a href=. If you don't find the sequence, read the next line; otherwise get the index of the sequence and go to step 2.
2. Search for the first instance of > after the index from step 1. If you don't find the symbol, read the next line; otherwise get the index and go to step 3.
3. Get the index of the first sequence of </a> after the index from step 2. If you don't find the sequence, read the next line; otherwise get the String between the index from step 2 and the one found in this step.
4. Validate the file found is indeed an image by checking the extension on the file name String from step 3. If it is an image, add to the array; otherwise read the next line.
5. Return to step 1 on the rest of the line (to ensure there isn't more than one image file on the line)

I "think" that algorithm should parse the directory the way you want. That is of course assuming that the sequence I used is always there and never changes.

yea auss, great, that is the way to go.
I'l work on it and you hear from me soon!

here is the file type searching method (should be rewritten):

   String line; // the line read from the file
                System.out.println(" BufferedReader is initiated");
                int i = 0;
                for (; (line = in.readLine()) != null;) {
                    System.out.print(i + "  > " + line);
                    //adding the checked correct image files
                    if (checkImageType(line)) {
                        imagefiles.add(line);
                    }
                    i++;
                }
                maximages = imagefiles.size();
                System.out.println(" the arraylist length is: " + maximages);
            } catch (IOException ex) {
                System.out.println("  can't download the file list ");
                Logger.getLogger(SlideshowApplet.class.getName()).log(Level.SEVERE, null, ex);
                System.out.println("  end of error message ");
            }
        }
        else
        System.out.println(" no fillename array is setup: " + url);
    }
 
 
    private boolean checkImageType (String f)  {
 
                String fl = ft.getContentType(f);  // MimetypesFileTypeMap ft;
 
                String type = fl.split("/")[0];
                if(type.equals("image"))  {
                        System.out.println("  Is an image:  <" +
                                fl.split("/")[1] + ">   ");
                        return true;
                }
                else  {
                        System.out.println("  Is NOT an image");
                        return false;
                }
    }

This method works on the file version of the webpage
But it wont work when uploading!
Anyway the alg. is to complicated (on of my mayor problems)
For now I have to correct some student exams (I am a musician).
but I'll turn back to this soon.
Any comments welcome

Lets take some distance to all this.
Why is this HTML stuff appearing?
Because that server is turning the output into a HTML page, right?
(It might be that php is generating that code, right Auss?)
The file version of the site does not do that and works just fine!

My first attempt of filtering out that HTML stuff failed, so
I have to rethink my method again.

Auss is right to say that the <a href=" string is an important identifier.
After getting this string I only need to read the content between the two quotes, right?
Or better: <a href=" is opening the string reader and " is closing it.

But there is a problem, what does one do with " inside a " --- " ?
So this one helps s.charAt(int i) == '"'
But there is still <a href=" ending into a "

so what to do here?

ps the <a href= identifier is

if (s.length() > 5) {
String sub = s.substring(0, 5);
if (sub.equals("href=")) {

I believe I am almost there, but still having some trouble (man it is not easy for me).
So I do the following
1) I save the complete directory line as a string called imgstring
2) Than I check if there are more tokens (divided by empty space)
3) Next I look for the href= string
until here all goes ok
4) when found 3) I empty imgstring and try to fill it again until "
but this part goes wrong! See the Do/ While loop

A string to be checked looks like this:
<img src="/icons/image2.gif" alt="[IMG]"> <a href="11149051_large2.jpg">11149051_large2.jpg</a> 15-Jun-2013 05:19 84K

while (tok.hasMoreElements()) {
                     //the token has several space units
                        String s = tok.nextToken();                         
                        if (s.length() > 5) {
                            String sub = s.substring(0, 5);
                            if (sub.equals("href=")) {
                            System.out.println(" is img token: " + s);
                                imgstring = "";
 
                                int count2 = 6;
                                do  {
                                     imgstring = imgstring + s.charAt(count2);
                                     count2++;
                                } while (s.charAt(count2) == '"');
                                System.out.println(" is img token filtered: "
                                                                    + imgstring);
                                System.out.println(); System.out.println();
                            }  
                        }
                     }

I believe the while (s.charAt(count2) == '"'); that is pr0bably alright?
But what about this:
String imgstring = imgstring + Character.toString(s.charAt(count2));
And this (al not working):
String imgstring = imgstring + s.substring(count2, count2);

**willemjar** · June 16th, 2013, 01:59 PM

I looked at it a long time and I do not understand what is going on here.

This is an example of a directory line:
<img src="/icons/image2.gif" alt="[IMG]"> <a href="COSTA%20BRAVA%201.jpg">COSTA BRAVA 1.jpg</a>

The above string gets tokenized (using empty-space)

The next is the output of the cited code at the bottom part.

is img token: href="COSTA%20BRAVA%201.jpg">COSTA
<C>
is img token filtered: C

 StringTokenizer tok = new StringTokenizer(line);
 
                     while (tok.hasMoreElements()) {
                     //the token has several space units
                        String s = tok.nextToken();                         
                        if (s.length() > 5) {
                            String sub = s.substring(0, 5);
                            if (sub.equals("href=")) { // finds the image string
                            System.out.println(" is img token: " + s);
                                imgstring = "";
 
                                int count2 = 6;
                                do  {
                                     imgstring = imgstring +
                                         Character.toString(s.charAt(count2));
                                         //    s.substring(count2, count2);
                                     System.out.print("<" + imgstring + ">");
                                     count2++;
                                } while (s.charAt(count2) == '"');
                                System.out.println();
                                System.out.println(" is img token filtered: "
                                                                    + imgstring);
                                System.out.println(); System.out.println();
                            }  
                        }
                     }

--- Update ---

Dear willem

why you don't try while (s.charAt(count2) != '"');

of course willem how utterly stupid of me

**willemjar** · June 16th, 2013, 05:39 PM

Pls give me some feed back concerning the applets

mywebpage

still testing things

some of my friends got this:

access denied (java.net.SocketPermission...

what is that about......

**willemjar** · June 17th, 2013, 02:49 AM

Dear Aus and All

This is really annoying I had it all working Yesterday (the several slideshow applets at my site) and now I get again a 403 error.
When reading this thread you'll find out that it all started with this 403-java/ server error. And after some help of Auss and me getting some what of a listen of a folder directory, I started to work to get the applets going.
The server generated a web page format of the directory and I wrote (having to take several obstacles) a filter algorithm that would deliver me a clean list of image files to download for the slideshows (there are like 8 different slides that all pickup a different folder).

I GOT IT GOING YESTERDAY BUT TODAY AGAIN THE TROUBLES (403 CODE) ARE HERE TO STAY!

Probably the server observed what I was doing (and succeeding) and "slammed the door in my face". Sure the server is gratis and I will write an email but there is not much to complain about, right?

I sincerely believe now that there is no future for Applets anymore (even when it worked for one night on my Mac, several friends of mine got different error codes on their computers like ClassNotFoundException and access denied (java.net.SocketPermission). It is really very sad because now I have to look up one of this pre-cooked slideshows and adjust my page to it (when I opened the side one firefox --wink, wink-- appeared a flash plugin installing window…… is the server giving me a hint…..).

It is already a global issue, guys: in order to stay safe and to "have security" we need to give up our freedom of expression and our room to move, right!

--- Update ---

Dear Sir Madam

I opened a free website space at you server and thank you for that.

I am using that space mywebpage for testing a slideshow applet. The trouble the applet goes through is that it needs to list several directories of some image file names (exclusively through code-base command). The path is http://willemii.orgfree.com/tryoutwe...ages/principal (or some more folders at slideshowImages level).

Your server let me do that yesterday, but today I got a "HTTP 403 access denied error" from the server. Sir, Madam, I am not peaking into your server directories. I am only interested in that specific file path and I am asking you to grant me a permission to do so.

Thank you ones again for the free webspace

willem

**willemjar** · June 17th, 2013, 04:47 PM

Got an answer from the server guys:
"Hi, if you upgrade that error will disappear. It is a hotlink protection for free accounts."
Oh.......

**willemjar** · June 20th, 2013, 05:01 PM

Ok next struggle signing the applet, this might do it:
(working with Netbeans)
Here's how you do it:

1. Open your project.
2. Go to File --> Project Properties.
3. Click "Web Start"
4. Click "Enable Web Start"
5. Under Signing click customize and select the correct option (self sign should be enough)

Build the project. It'll create some jnlp's and other stuff but the jar is signed as well.

Javier A. Ortiz Bultr

Since I have the applet files in a jar file (should be concerning the signature)
I've got a new problem: java.lang.ClassNotFoundException: slideshowapplet.SlideshowApplet.class

The applet tag is now:

<APPLET codebase="classes"
code="slideshowapplet/SlideshowApplet.class"
archive="slideshowapplet/SlideshowApplet.jar"
width=750 height=450>

the path is (from code base) classes/slideshowapplet/slideshowapplet.jar
and the jar contains the SlideshowApplet.class

So please help me what is going wrong now

--- Update ---

at the META-INF there is under INDEX.LIST (whatever that is)

JarIndex-Version: 1.0

slideshowapplet.jar
slideshowapplet

--- Update ---

changed the applet tag into

<APPLET
archive="slideshowapplet/SlideshowApplet.jar"
code="slideshowapplet/SlideshowApplet.class"
width=750 height=450>

and the relative path is now slideshowapplet/slideshowapplet.jar
Still get the error but there is a strange thing happening!
I find this path listed, which is correct: network: Conectando http://willemii.orgfree.com/tryoutwe...owApplet.class
BUT NEXT I FIND A RELATIVE LINK OF MY HARD DISK.... WOW WHERE IS THIS COMING FROM

--- Update ---

Usando versión JRE 1.6.0_45-b06-451-10M4406 Java HotSpot(TM) 64-Bit Server VM
Directorio de inicio del usuario = /Users/willemcargar: clase slideshowapplet/SlideshowApplet.class no encontrada.
the red is that link
man this stuff is really confusing....

--- Update ---

It gets weirder the class name is: SlideshowApplet.class
The jar name is: slideshowapplet.jar
But the path shows:
network: Conectando willemii.orgfree.com/tryoutwebsite/slideshowapplet/SlideshowApplet.jar con proxy=DIRECT
SlideshowApplet.jar
So I changed the capitals manually, wow where is this coming from?
AND NOW THINGS ARE ADVANCING SOME MORE

--- Update ---

The classes are loaded
but there is a problem with certificate (do not know why that is in spanish
but you guys know spanish it is the US second language, right:
security: jpicertstore.cert.getkeystore
security: Iniciar la comprobación del reemplazo de la autoridad de certificación raíz
security: La autoridad de certificación raíz no se ha reemplazado
Ignored exception: java.security.cert.CertificateException: La configuración de seguridad no permitirá dar permisos a los certificados autofirmados

--- Update ---

The error says (in spanish) as if the certificate is NOT signed"

so here is the whole thing and there is (on top) still the link to my hard disk

The famous error code is still there probably because the certificate is there
but it is like it is not signed.... (so how to sign that d--- thing?)

any suggestions what is going on
