java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager

Trying to run a basic JPA program using createEntityManagerFactory, EntityManager and persistence.xml.....Everything compiling fine. I'm running it as a standalone Java application on Weblogic 10.3. First I got this error on running.

Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager, after that I did some search on the net and created the wlfullclient.jar and included it. After that I'm getting the below error.

Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/logging/LogEntryFormatter.

Tried removing wlcommons-logging.jar whenever facing an issue, but it doesnt help, it gives some other error when it is removed.

Can some one help please.

For folks who are struggling with this error, I'm posting a solution after

When you face this error java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager, first remove the weblogic system libraries, then generate the wlfullclient.jar file(steps are in the net) and add it to classpath.

Ultimately after several inclusion of other jar files which wasnt included, it worked.

All the best.
