Hi Chris,

Because org.apache.xerces.jaxp.SAXParserFactoryImpl seems to be related
to Eclipse Web Tools, the eclipse.webtools newsgroup might be the best
place to pose your questions about the symptoms you're seeing.

I've added the eclipse.webtools newsgroup to this reply, so they can see
the start of this thread.

Hi Chris,

Unless you're trying to run a Web Tools ant task I don't think this is WTP
related. However, the parser in question is from the Apache Xerces [1]
project. In this context Xerces is a Java based XML parser. You're likely
getting this error because Xerces is not included in your JRE. (I'm not
familiar with the Max JRE but this used to happen with older Sun JREs.)

Xerces is available as a bundle from the Orbit project [2] and is
available in Eclipse (if installed) in the bundle org.apache.xerces. Add
this bundle or the Xerces jar to your path and you should be good to go.

Lawrence
