[xep-support] Servlet Connector issue

Update ...
 
I have now installed the latest version of RenderX (4.4) and STRUTS (1.2.7)
and I have the same problem (still running WebLogic 8.1 SP2): 
If xep.jar is first in the classpath (causing saxon.jar and xt.jar to load
because of the manifest) the STRUTS ActionServlet will not initialize:

If xep.jar goes in the back of the classpath the STRUTS ActionServlet
initializes, but the RenderX transformation process hangs/produces a blank
page. It must be an XML parser version issue.
 
Any advice and/or comments would be appreciated.
Thanks,

It is a classpath issue. Unfortunately it looks like xep.jar needs to go
first in the classpath, but so does xmlparserv2.jar from Oracle ... 
Any suggestions would be appreciated.
Cheers,
Morten

Subject: [xep-support] Servlet Connector issue


I am trying to run a servlet under WebLogic 8.1 to transform an XML file
into PDF using an XSL stylesheet. My application and the servlet connector
from the dev kit both return a blank page.
The code with a few modifications runs fine as a standalone application.
I can forward the code if necessary.
Any advice would be appreciated.
Cheers,
Morten, Genentech
