The problem is releated to the use of org.apache.xerces.parsers.SAXParser
in the Action bean it can't create.
A call to SAXParser.setContentHandler(), can be left in place, but
when I remove the calls to SAXParser.reset() and SAXParser.parse(), (I
have to remove both) the VerifyError problem goes away.
But of course the Action bean isn't very functional.
I thought this might have something to do with colliding versions of
xerces.jar, so I've replaced
<pathelement location="${deploy.home}/WEB-INF/lib/xerces.jar"/>
with
<pathelement location="/usr/share/java/xerces.jar"/>
,removed xerces.jar from the WEB-INF/lib directory of the compiled
webapp, and done a complete rebuild of the webapp, but I still get the
VerifyError.
I belive /usr/share/java/xerces.jar, which is the the version
installed by the xerces-j 1.4.4 RPM, is the version used by tomcat
4.1.12 (is there a way to find out what xerces.jar file it loads?).
Any hints and guesses that might shed some light on this problem, are
appreciated!
Thanx!
