I upgraded from 2.1.3 to 2.5.0 on WAS7 Windows Server 2008(?) 64-bit and everything just worked. I haven't upgraded to 2.6.0 yet. The initial fight of getting CXF to run on WAS7 using jython to set the class loader order was an quite a battle but upgrading CXF itself was easy.

(experts on this list like Daniel, Sergey, and Glen will know far more).... If you are already using CXF (any version), wouldn't these steps have had to be done to get it to run in WAS 7 regardless? If that step *is already done*, then there may be more to this than just the classloader. I have only used CXF 2.6.0 with Tomcat. We are not yet using it with our WAS 7 servers (at this point). Wish I had more info. On Thu, May 24, 2012 at 1:00 PM, Mandal, Debdayal < [email protected]> wrote: > Thank You Mark for your response.
