    Using Eclipse 3.1 I created a MyEclipse Web Project and when I open the web.xml file, the error says:

    Unable to create this part due to an internal error. Reason for the failure: Editor could not be initalized. When I click the ‘Details’ I see the following Exception:

    It looks like you have a separate install of EMF (And likely GEF) that is incompatible with MYEclipse. Can you check your <eclipse dir>\plugins directory for emf or gef plugins? Do you have VE installed?

    When I remove the following directories from under <eclipse>\plugins, all works well!!

    org.eclipse.emf.ecore_2.1.0,
    org.eclipse.emf.common_2.1.0, and
    org.eclipse.emf.ecore.xmi_2.1.0

    Thanks!!
