Edson,
Thanks for your reply. I've also been able to trace the issue to the xml
parser incompatibility but seem to have a proper(??) version of the
xml-apis.jar in my classpath.
The versions used are as follows:
xercesImpl-2.7.1.jar
xml-apis-2.0.2.jar
While deploying on weblogic, I'm having the following stack trace:

which I tend to associate with the version discrepancy between Weblogic's xml
parser and the one used by drools.
It seems that swapping the parsers versions back to xercesImpl-2.6.2.jar and
xml-apis-1.0.b2.jar makes the problem disappear, but this needs a bit more
testing on our end to be confirmed.
Would appreciate more insights and comments on this.

Simeon Leyzerzon

Patrick and Simeon,
This same problem arose yesterday and it was an XML parser issue.
When working with JDK 1.4, you need updated XML parser libs added to
your classpath. This might me xerces for example, with xml-apis.jar also.
Here a similar post (but not related to drools).

Hope it helps.
