Oxygen XML Forum

I'm currently using the oXygen 6.0 plugin for Eclipse 3.0. I've now installed Eclipse 3.1
and when I install the oXygen plugin, either 6.0 or 6.2.6 I get the following error (wrapped
for readability):

Unable to create editor ID com.oxygenxml.editor.editors.xml.XMLEditor: DTD \
factory class org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl does not \
extend from DTDDVFactory.

I've downloaded and added the most current version of xerces to the classpath to see if
that was the problem. It wasn't. Any ideas?

Thanks,

Hello,

Release 6.2.6 of the <oXygen/> Eclipse plugin works around a context class loader issue related to loading Xerces classes but your case seems to be different. Do not add any Xerces version to the classpath, uninstall version 6.0 from Eclipse 3.1 and use only version 6.2.6, pass the -clean param in the command line which starts Eclipse, reproduce the error and post here the whole stacktrace of the error available in the Error Log view of Eclipse or even in the error dialog.

Regards,
Sorin

This is my first install of Oxygen. I restarted with -clean after the install (2 times to be sure).

Here is the stack trace when opening the editor:
