Subject Re: actual cvs source not running?
Date Thu, 02 Aug 2001 18:03:12 GMT
Thanks, I fixed this one.  It was caused by a copy of the saxon.jar XSLT
processor in the tomcat lib, in addition to jaxp, xerces and xalan.  It seems
that jetspeed worked on windows because the tomcat startup script used the
file order on windows when assembling the CLASSPATH, which put saxon.jar last.
Whereas the tomcat start script on Linux assembled a CLASSPATH with jars in
alphabetical order, which put saxon.jar before xerces and xalan.

I need saxon for another application running in tomcat, but due to classloader
issues, I am forced to put saxon.jsr in the tomcat classpath instead of in the
other application's webapps lib.  saxon.jar must be in the same classloader as
jaxp.jar (at least, that appears to be the root cause).

These conflicts between different XML parsers and different versions is easily
the biggest issue in app server deployment...

Thanks,
  Dave
