Thirty Party Jars.

Question

Hi,
I have an application using a thirty party jar file. It works fine in Eclipse and also it compiles in Unix (I put this Jar file in the class directory in both windows and Unix. When I try to run the application using web start I get a NoClassDefFoundError(). How can I make my application work with thirty party jars? I've also tried putting this jar in my jnlp file:
<?xml version="1.0" encoding="UTF-8" ?>
<jnlp spec="1.0+"
codebase="http://xxx.xxx.xxx.xxx/temp" href="simple.jnlp">
<information>
<title>TEST</title>
<vendor>Test</vendor>
<description>Just A test</description>
<homepage href="http://xxx.xxx.xxx.xxx/temp/package.html"/>
<offline-allowed/>
</information>
<security>
<all-permissions/>
</security>
<resources>
<j2se version="1.4+"/>
<jar href="FileDate.jar" main="true" />
<jar href="jsch-0.1.24.jar" />
</resources>
<application-desc main-class="Exec">
<argument>command-line-argument</argument>
</application-desc>
</jnlp>
where FileDate.jar is my jar and jsch-0.1.24.jar is the thirty party jar. By the way, this jar is in the same directory together with my jar file and the jnlp file.
Here is the error:
java.lang.reflect.InvocationTargetException

     ... 11 more
where Exec is my main class and UserInfo is a thirty party class.
Also, here is part of my code:
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.JSchException;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.UserInfo;

public class Exec{
public static void main(String[] arg){
try{
JSch jsch=new JSch();
String host = "[email protected]";
String user=host.substring(0, host.indexOf('@'));
host=host.substring(host.indexOf('@')+1);
Session session=jsch.getSession(user, host, 22);
session.setPassword("xxxxxxxxxxxx");
// username and password will be given via UserInfo interface.
UserInfo ui=new MyUserInfo();
If I execute from Unix:
gij -jar FileDate.jar
I get this:

Thanks for your help.

Hi, I had exactly the same problem.
My 3rd party library are JFreeChart.jar and JCommon.jar
And my main-class is osciloscopio.class
So I included in osciloscopio.jnlp:
<resources>
<jar href="Osciloscopio.jar"/>
<jar href="JFreeChart.jar/>
<jar href="JCommon.jar/>
</resources>
And I had:
Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission read)
