[Opensource] Expresso 4.1 RC1 not working with tomcat 4.04

[larry hamel]

Hi Mike,

You are absolutely right about how the class loader should work.  Tomcat's hierarchy of class loaders should permit the correct xerces to be used from a Web applications private lib directory.

Perhaps xerces has a subtle version-dependent issue where an old class is not present in the new library, but somehow gets called by it.

Anyway, I'm glad you saw the bug too!  Misery loves company :-)

Replace the Xerces included in CATALINA_HOME/common/lib with that included in the WEB-INF/lib.  [You'll want to replace xerces.jar with both xercesImpl.jar as well as xmlAPIs.jar].  That should do it.

When I get a solution we'll post an RC-2 since this error will significantly block Expresso from being able to work with other Containers.
