HI all,

I had created one SWT(java) application using net beans IDE. As i set all the jar files which is required to run this application. its running in development platform. but when i build this application in net beans and try to execute the jar file its giving error.



C:\Documents and Settings\Asif>java -jar "C:\Documents and Settings\Asif\My Documents\NetBeansProjects\JavaApplicatio\dist\JavaApplication2.jar"

following is the error.


Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/events/MouseListener at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$000(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at javaapplication2.DragAndDropExample.main(DragAndDropExample.java:23) Caused by: java.lang.ClassNotFoundException: org.eclipse.swt.events.MouseListener at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) ... 13 more


And Here is the Source code.

its having two files.

I suspect that even if you used code tags -and you absolutely should do that- this would still be too much code to ask anyone to go through and try to understand.

This always a red flag, though - you must do proper error handling:

catch(Exception ex)
{
}


C:\Documents and Settings\Asif>java -jar "C:\Documents and Settings\Asif\My Documents\NetBeansProjects\JavaApplicatio\dist\JavaApplication2.jar"

Does this jar file contain the MouseListener class that's missing? If not, then you need to add that to your classpath.
