After downloading and installing MyEclipse 6.0 GA (full stack). I am trying to configure a Weblogic application server by going to Window -> Preferences -> MyEclipse -> Application Server and then selecting Webloic to configure a server but every time I select “Weblogic” I am getting an error window that says

Unable to create the selected preference page.
com.genuitec.eclipse.easie.weblogic.preference.WeblogicFamilyPreferencePage

and I am unable to configure a Weblogic server. All of the other server configs are working ok. I am able to configure a Tomcat server with no problems.

Here is an excerpt from the log file

!MESSAGE Problems encountered starting up plug-in: “org.osgi.framework.BundleException: Exception in org.eclipse.core.internal.compatibility.PluginActivator.start() of bundle com.genuitec.eclipse.easie.weblogic10.”.

[Scott Anderson]

The issue is likely that the Eclipse plugin cache got stale as it sometimes
does not cleanly rebuild after updates. To rectify the problem you’ll need
to restart Eclipse with the -clean flag one time: eclipse.exe -clean

More information on using -clean is in the FAQ here:
http://www.myeclipseide.com/PNphpBB2-viewtopic-t-10280-highlight-clean.html

That should resolve the problem.

-clean did not help, but re-installing MyEclipse solved the problem.
