I continuosuly get the below error message in my eclipse environment
java.lang.NoClassDefFoundError: org/apache/log4j/net/JMSSink
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.net.JMSSink
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)
Exception in thread "main"
- I installed and deleted Visual Basic 6 for short period. And this problem started after the unistalling VB6. I remember while installing VB6 it showed a message saying VB6 will do some changes in java environment
- After uninstalling VB6, and seeing the above problem. I tried reinstalling the jdk and it did not help.
- These codes were already running before.
I don't know what else I can do. Any help will be appreciated.
Best Regards,

looks like you are missing a jar file. You need to add the jar that
contains the missing class file to your build path.

I finally solved the problem.
I was using Galileo Eclipse. I used Helios and the problem got solved.
I still don't know how but, probably there was some sort of corruption in My Galileo Eclipse installation.
Now I will continue with Helios.
I had beed trying to solve this problem day and night for nearly 3 weeks.
Thanks,
Best Regards,
