Further to this, I added Xerces to /lib directory of .war file only to be faced with the following exception.

I am currently attempting to get a plug-in working with a webapp and keep experiencing the exception error stated above. I am aware that this may mean that specific .jar files are not included in the classpath for my servlet. I have posted part of my Tomcat server log for further exception report.
