Tim McConnell commented on GERONIMODEVTOOLS-344:
------------------------------------------------
According to the stack traces it appears there is a classpath clash somewhere
with:
\javax\xml\namespace\QName.class
which is in fact included in xpp3-1.1.3.4.O.jar. So what I did was to use the
xpp3_min-1.1.3.4.O.jar, which appears to be a minimal version of the xpp3 jar
since it only has two classes (XmlPullParser and XmlPullParserException) so
there is no clash. A that I was able to define a dynamic web application,
deploy, and execute it with no errors. I could also do that same with the
calculator-stateless ear file. In fact, the GEP never uses xpp3 directly --
it's used somehow by the xstream class, which is use to create/read/update the
servermodele.info file for WTP and this is isolated to a single class (i.e.,
ModuleArtifactMapper).
Not yet sure this is the optimal solution but one possible alternative.....

> During the release of the GEP 2.1.0 we encountered problems with the
> xpp3-1.1.3.4.O.jar file when trying to create a new dynamic web problem
> (i.e., unhandled event condition). Need to investigate and understand why so
> that we can use the same version of this artifact that the server is using.
