Re: XMLC problem with XML files |
Just a note. The issue is having xercesImpl.jar and
xmlParserAPIs.jar in CATALINA_HOME/common/endorsed while the xerces
version XMLC uses is in CATALINA_HOME/shared/lib. The remedy is to
stop Tomcat, remove the jars from common/endorsed, and restart
Tomcat. Everything will work fine then.
I have made some notes as to why this is on the BarracudaMVC list:
http://barracudamvc.org/lists/archives/barracuda/2003-January/005749.html
If David Li and Richard Kunze (and others, of course) could take a look
at the issue, that would be fantastic. If it could be solved in a
way which allows us to leave the jars in common/endorsed, it would make
it that much easier to provide instructions for deploying XMLC/Barracuda
apps on Tomcat. If it can't be fixed in the code, at least we have
a workaround...but it isn't ideal. I guess that we can use this as
an incentive to migrating XMLC to Xerces2 instead of Xerces1.

Hey folks,
Anyone want to comment on the following error we've just noticed in
Barracuda? Basically, everything seems to be working fine with regular
HTML
files that are compiled via XMLC. As soon as we even reference an XML
file
compiled by XMLC, however, the following error occurs:

I know this used to work just fine (pre XMLC 2.1?)
