Thread: edit .conf file in /etc linux (java SE)

Hi everyone!
This time I have a java SE web start application hosted in a Linux/Debian server
I need to edit a .conf file from the /etc directory folder in the Debian server but I have no idea how to access this file if it's not within the public /www folder. I think it has to do with apache users and permissions, but my linux knowledges are just few

Thanks in advanced!

I only need to modify one .conf file from /etc/asterisk , I have no problem giving rights to edit it. In fact, I made Apache to show me the file to the public and I can retrieve it from the server (read it), but when I need to save the changes (or replace the file at the same directory) I am having problems because I originally have a URL text, then parse it to String in the application, and then need to upload or rewrite it to the URL. That last step is giving me an headache!

Thanks in advanced for your help copeg.

I have tried some codes, but none of them work

Just as simple as trying to create and write a .txt in the server

// Open an output stream
URI uri = new URI("http://172.16.64.54/test/myfile.txt");
File file= new File(uri);
fout = new FileOutputStream(file);

// Print a line of text
new PrintStream(fout).println("hello world!");

// Close our output stream
fout.close();

throws Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: URI scheme is not "file"

Obviously I dont know how to manage Files and URLs when writting. The folder test is created with all permissions (777)
I really need to write or copy a file to the server. Any ideas?

There is a server (Debian) that host the .jar files (in the public /www directory of Apache). I execute them thru java web start (it downloads the resources to the local machine) on Windows. I need to modify or replace a file located in /etc/asterisk folder within the debian server. How can I upload or copy a file to the debian directories from a java .jar running in a windows client?

ok I understand, maybe I can make a php or perl script to do this. How do I give the information to the script? Is there any class in java to communicate with a server side script? thanks for your help!

Thanks for the link, I am already trying to figure it out.
Its a good idea to use URL passing to edit a whole .conf file? I mean its a long string, there is no problem sending it to a php script via url?
I dont know about servlets, but I think they dont work in Apache, its better to set up a server that executes them ? (I think tomcat and glassfish are the ones)

thanks a lot copeg

Ok I made a php script to edit the .conf file and it works fine giving apache the permissions. But the problem is sending the information from JAVA to PHP script.
JAVA:
URL url = new URL("http://172.16.64.54/prueba/url.php");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write("test);
wr.flush();

and the PHP script is supposed to be executed, but it doesnt. When I type the php script in the browser, it works (forget about the passing arguments) but when I execute my java program, it doesnt execute!
Is there another class to work with http urls?

You may need to read the response for the request to be sent. I'm fairly sure it's a 'lazy' process. Read the API docs for HttpUrlConnection - I think reading a response header or the response body will complete the exchange.

I made it work, thanks a lot. I will check HttpUrlConnection for more information.
