When the WTE feature is added to the workspace, the project 'IBM XML Parser for JAVA' is added as well. This project CONTAINS old DOM Level 1 'org.w3c.*' interfaces. JDOM relies on DOM Level 2, and therefore conflicts with this project.

The solution is to do the following:

1. Change workspace owner to ADMINISTRATOR
2. Create open edition of the project 'IBM XML Parser for Java'
3. Delete all the packages that contain org.w3c.* interfaces
4. Version the project.
5. Create a new Project for DOM Level 2 parser such as Xerces
6. IMPORT all Xerces classes including org.w3c.* interfaces (you can use a completely different project for those interfaces if you want to work with other PARSERS)
7. Version the Xerces project
8. Create a JDOM project and import jdom classes into it. Version the project.
