[oXygen-user] XSLT debugger - Xalan extension - class not found exception

Hello, I want to try out Oxygenxml's XSLT debugging feature, but the debugger stops with a class not found exception for the Xalan extension I'm using. I did put my class files into the \eclipse\plugins\com.oxygenxml.editor_4.1_E3\lib directory, which works fine when I'm applying a transformation scenario outside of the debugger. How can I tell the debugger where my classes are? I'm using: Eclipse 3.0RC2 Oxygenxml 4.1 E3 Xalan 2.5.1 Xerces 2.4.0 Windows XP Java 1.4.2_03 Thanks, Achim
