Executing a java class in izpack installer

Hi,
Do you know how to use Executable tag to execute a java class containing Main() methode?
I need to run a single java class using the izpack.
I tried to insert the class in that tag but didn't compile (in the documentation they note that class is one of the attributes of excecutable tag).
Should I do it in a different way or did I miss some thing?
Please advise
Thanks

Looks good, but there don't seem to be any links to a manual on their homepage
be something like:

<executable targetfile="java.exe" args="class to run"/>

Hi,
Thanks for the respond.
Itried the following with no success.

 <pack name="class test" required="no">
            <description>class test</description>
        <executable targetfile="C:\j2sdk1.4.2_02\bin\java.exe" args="C:\ClassTest.class"/></pack>

a simple class that copy files : ClassTest.java:

import java.io.*;

public class ClassTest {
       
    public static void main(String[] args) {
          try{
                File fs= new File("c:\\BasePath.txt");
                File fd= new File("c:\\temp\\test.txt");
                copy(fs,fd);
          }
          catch(Exception ex){
          }

    }

 private static void copy(File src, File dst) throws IOException {
        InputStream in = new FileInputStream(src);
        OutputStream out = new FileOutputStream(dst);
   
        // Transfer bytes from in to out
        byte[] buf = new byte[1024];
        int len;
        while ((len = in.read(buf)) > 0) {
            out.write(buf, 0, len);
        }
        in.close();
        out.close();
    }  
}

After compiling and running using comand prompt it works fine but not using the installer.

Please advise.

What do you mean about online docs?
> <executable targetfile="C:\j2sdk1.4.2_02\bin\java.exe" args="C:\ClassTest.class"/></pack>

try:

<executable targetfile="C:\j2sdk1.4.2_02\bin\java.exe" args="ClassTest"/></pack>

hi,
first, I thank you for your reply.
I tried the following with no success again:

<executable targetfile="C:\j2sdk1.4.2_02\java.exe"  stage="postinstall" keep="true" failure="warn">
 <args>
 <arg   value="C:\IzPack\sample\Install\InnerClasses\com\Classes\CopyFile2"/>
  </args>
</executable>

I got an error=2 msgbox.
please advise if it can be done.and if so how can I send more args to the main() function?
I succeded doing that with a jar file but I prefer to simplify that as you advised.
Thanks

Hi,
Yes I have tried many ways ex:

<executable targetfile="C:\j2sdk1.4.2_02\java.exe" args="C:\IzPack\sample\Install\InnerClasses\com\Classes\CopyFile2" keep="true" failure="warn"/>

And

        <executable targetfile="C:\j2sdk1.4.2_02\java.exe" args="CopyFile2" keep="true" failure="warn"/>

(by the way, if I do as above how the installer will know where the class located?)

I tested the class using >java CopyFile2
And it works.

CopyFile2 is idetical to ClassTest above.

Please advise....
Thanks a bunch for your help.

Well, Using your solution doesn't work still.
I am more then glad to give you the points though ,You have helped me in the past and I appriciate you're helping me now.
What do I do wrong here? Should I specify a package in the class itself?
If youre not giving up on me I will wait for your help.
Again thanks

Mybe there should be a way to activate the main()?
May be worth asking on the mailing list:
