We are currently using the gnu japx implementation for our xml parsing.
I encountered several problems in the last days when I tried to bind our
stuff to an AXIS web service. I was able to identify this as a library
conflict (supposingly with the xerces parser tomcat uses) and I can
resolve the problem for most of the cases by putting just the minimal
amount of jars in my classpath.
But one problem persists: As soon as I put gnujaxp.jar in
../tomcat/webapps/axis/WEB_INF/lib/ to make it accessible to my web
service and then call it, the whole axis runtime screws up with following
exception:
org.apache.axis.InternalException: org.apache.axis.ConfigurationException:
org.apache.axis.deployment.wsdd.WSDDException: Must include type attribute for Handler

Then I changed to Xerces and everything was fine.
Does anybody have any clue what's going on?
Since Xerces and GnuJaxp are both JAXP1.1 complient I should be able to
use them interchangeably, right?
BTW: The decision to use GnuJaxp was made before I got involved but I'd
rather prefer Xerces. If anybody has some absolutely convincing arguments
why to change to Xercex let me know.
Thanks.
