Underlying implementations of SOAPBody, SOAPElement etc.

[Chris Mannion <ch...@nonstopgov.com>]

Hi All

I'm not sure this is exactly the place to be asking but I can't think of
anywhere else so here goes.  I have the same piece of code running on two
different Tomcat installations, one Tomcat 5.0, the other Tomcat 5.5.  The
code calls and web service and produces a javax.xml.soap.SOAPMessage in
response.  Having noticed a slight difference in behaviour I debugged and
found that on the Tomcat 5.0 system the underlying implementations of the
javax.xml.soap interfaces (SOAPBody, SOAPElement etc.) were Axis classes
such as org.apache.axis.message.SOAPBody.  On the Tomcat 5.5 system the
underlying implementations are all from a
com.sun.xml.internal.messaging.saaj.soap.impl package.

My question is what would be causing this difference, I thought perhaps
libraries in Tomcat but have tried replacing all my libraries on
Tomcat 5.0(including common, endorsed and those in the webapp) with
those from Tomcat
5.5 but that didn't make any difference.  Has anyone got any more ideas?

I don't believe Tomcat ships with any SOAP classes at all. Are you using
any 3rd-party JARs in either install (like AXIS)? Alternatively, are you
using different versions of JWSDK or anything like that? How about
different JVM versions?

Er, you should undo that. ;)

I would find out where the classes themselves are being loaded. Check
your app's WEB-INF/lib directory, Tomcat's common/lib, shared/lib and
endorsed directories, and your JVMs "endorsed" directories, too.
