I am very new to the MyEclipse Workbench, so be kind. I am using eclipse 3.1 and workbench 4.1 I am using JDK 1.5.5

I am working through an exampe demo from this site involving Hibernate and struts.

When I double click on the struts-config.xml file, I receive the below error. It has something to do with the MyEclipse Struts Editor.

Problems occurred when invoking code from plug-in: “org.eclipse.jface”.

Can someone point me in the right direction for this error?

Thanks for being nice.

okay I figured it out……..

Had to re-installed everyting from scratch. Everything worked as design. Problem was I was using old workspace…..This confused MyEclipse.
