i had the same problem with websphere... i had to add following JVM 
parameter 
-Djavax.xml.stream.XMLInputFactory=com.ctc.wstx.stax.WstxInputFactory 

with another version i had to drop the stax2 jar into a shared folder 
because the 
classloader wouldn't respect my parameter

g,
kris

ClassCastException after upgrading to 5.1.0.5








After upgrading from 5.0.18 to 5.1.0.5 my application fails to start when
deployed on a weblogic server. I think this has to do with the usage of 
Stax
in the TemplateParser. I have tried to override the implementation in my
weblogic-application.xml with

 <application-param>
  <param-name>javax.xml.stream.XMLInputFactory</param-name>
  <param-value>com.ctc.wstx.stax.WstxInputFactory</param-value>
 </application-param>

but I still get the following exception:

Caused by: java.lang.ClassCastException:
weblogic.xml.stax.XMLStreamInputFactory

Is there any way around this problem?
