Thread: Running Program in UNIX with package

Hi everyone

let's say i have a program in UNIX directory /home/me/java/src

package bin;
 
public class HelloWorld {
       public static void main(String[] args) {
               System.out.println("Hello World");
       }
}

I have manage to compile it successfully(class file will be in bin directory) using command below:
javac -d /home/t_bmf/java/bin HelloWorld.java

My problem now is how would I execute the class in bin directory in UNIX?
I already tried different ways on how to execute it as suggested in my internet research
The one I tried is this:
java $CLASSPATH:.:bin/HelloWorld
but I got this error message:
Exception in thread "main" java.lang.NoClassDefFoundError: :/:bin/HelloWorld
Caused by: java.lang.ClassNotFoundException: :.:bin.HelloWorld
at java.net.URLClassLoader$1.run(URLClassLoader.java: 202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.j ava:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:3 06)
at sun.misc.Launcher$AppClassLoader.loadClass(Launche r.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:2 47)
Could not find the main class: :.:bin/HelloWorld. Program will exit.

Thank you for your Help!..

After compiling try going to the directory java, and from there execute using

java bin.HelloWorld


It might work

thank you ankurt
it works now..
so it means that the way to run a program with package is through its parent directory right?
well i hope i can do it together with jar files..
I just need to add the -cp and $CLASSPATH right?
Thank you so much for your time..

--- Update ---

Hi again..
i have bin, src and lib directory inside Java directory which must contains:
bin all compiled programs (.class)
src all program source (.java)
bin all jar files

I can only compile a program together with jar files if those jar files are in same directory of .java files
this is the command that i used
javac -cp $classpath:.:first.jar:second.jar -d /home/me/Java HelloWorld.java
but i don't want this. I want the jar files to be located only in lib directory.
I tried this command:
javac -cp $CLASSPATH:.:home/t_bmf/Java/lib/first.jar:home/t_bmf/.Java/lib/second.jar -d /home/t_bmf/Java TestJar.java
but i got this error:
TestJar.java:3: package firstjar does not exist
import firstjar.FirstJarPrint;
^
TestJar.java:4: package secondjar does not exist
import secondjar.SecondJar;
^
2 errors

I'm sorry, I'm just new in UNIX. i usually do programs in windows and i can only access our server remotely..
Thank you for your time..

--- Update ---

I made it now.. using this command
javac -cp ".:/home/t_bmf/Java/lib/FirstJar.jar:/home/t_bmf/Java/lib/SecondJar.jar" -d /home/t_bmf/Java TestJar.java
Thank you..

Great. You have started solving your problems yourself...
