Hi,
I must be doing something wrong, but it seems that xerces isn't finding my schema (mentioned in my schemalocation hint in my instance document). I searched for answers on the archive and also on the web, but have not found anything that has worked.
Here are my files:

---------------------------------------------------
Sorry if that's overkill, but I figured I'd err on the side of too much info rather than too little. Basically, when I try to parse/validate this XML file using xerces DOM, I get lots of errors such as:
Error at file /export/home/newbie/sharring/Dev/HEAD/ACS/LGPL/CommonSoftware/task/bin/psetdef.xml, line 5, char 126
Message: Unknown element 'psetdefTypes:parameterset'
which indicates to me that it isn't finding my schema/xsd document per the schemalocation hint. I've tried fully-qualified path, just file name, file://file-name, etc. and no matter what, it never finds it. Any ideas what I've done wrong?
Thanks,
