Hope this helps....my associate also sent me this:
- One of the debug statements was to find out if it was using
org.apache.cxf.io or org.apache.cxf.attachment.DelegatingInputStream.
- I'm trying to cast this to an InputStream and I think this is not
working...
- If I set an io.DelegatingInputStream with data (as in the JUnit test) it
works.
- The attachment one isn't working.
Thanks...hope the additional information helps...jay
