RE: java.lang.NullPointerException creating org.apache.xerces.par
sers.SAXParser
Thanks for the response Jeffrey. Is there somewhere I can get a hold of the
latest cvs xerces.jar or do I have to get cvs all setup and build the jar it
myself?
I took a look at the recent changes to the source files involved and I
didn't see anything that looked different in the problem areas, but I agree
it is a good idea to make sure the problem still occurs on the latest code.
Thanks,
Eric

Sorry, it it monday and my coffee load is just kicking in.
I noticed mention that you are using Xerces 1.1.3.
You should try latest cvs build to see if this is still reproduceable.
