I've used axis 1.2, maybe the parent classloader i didn't use, maybe the axis version.

Hi all;
I do not know I am giving the correct answer , I did the same kind of thing in Axis2 to load jars in lib directories , there I got the create a URL [] getting url from each and every jar in the lib directory , and it worked perfectly with me. Following are the code that I used ;
public static ClassLoader getClassLoader(ClassLoader parent , File file) throws DeploymentException {
URLClassLoader classLoader;
if (file != null) {
try {
ArrayList urls = new ArrayList();
urls.add(file.toURL());
//if lib is simple
File libfiles = new File(file, "lib");
if (libfiles.exists()) {
urls.add(libfiles.toURL());
File jarfiles [] = libfiles.listFiles();
for (int i = 0; i < jarfiles.length; i++) {
File jarfile = jarfiles[i];
if (jarfile.getName().endsWith(".jar")) {
urls.add(jarfile.toURL());
}
}
}
//if lib is capital
libfiles = new File(file, "Lib");
if (libfiles.exists()) {
urls.add(libfiles.toURL());
File jarfiles [] = libfiles.listFiles();
for (int i = 0; i < jarfiles.length; i++) {
File jarfile = jarfiles[i];
if (jarfile.getName().endsWith(".jar")) {
urls.add(jarfile.toURL());
}
}
}
URL urllist [] = new URL[urls.size()];
for (int i = 0; i < urls.size(); i++) {
urllist[i] = (URL) urls.get(i);
}
classLoader = new URLClassLoader(urllist, parent);
return classLoader;
} catch (MalformedURLException e) {
throw new DeploymentException(e);
}
}
return null;
}
Thanks,
Deepal

Subject: Re: custom classloader
The class Boot begins downloading upgrades from web and then starts the main application class. I use several classloaders, one per operation. The last one is the application main classloader.
I began using a URLClassloader and a recursive jar finder method to add .jar to it. And it didn't work. Then i tryed with ClassLoader.getSystemClassLoader() and works. I don't know the differences but now works.
This is the code that works (bolded code is the first attempt):
package com.defactops.smartcv.swt;
import java.io.File;
import java.io.FileFilter;
import java.lang.reflect.Method;
import java.net.URL;
import java.net.URLClassLoader;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
