This is hopefully easy?

I'm new to eclipse & myeclipse, installed them both today. Tried to create a new jsp and got the following error log entry: Problems occurred when invoking code from plug-in: "org.eclipse.jface".

I have included the first few lines of the StackTrace below:

OK, I found the problem in the install section of the forum, sorry for the unecessay post

What is the solution for this?

change the shortcut that starts eclipse and add a -clean to it, then restart... You can remove the clean after the first restart.

delete these files under configuration but not include config.ini
after restart myeclipse

In the latest version of MyEclipse (version 5.1.0), we detect this situation automatically and will perform the "-clean" and restart for you.
