This is probably a good place to pose this question. I'm guessing someone will
know what is going on, and perhaps http-client has a solution.
You will recall that recently I created a "proxy" servlet to deal with NTLMv2
authentication because not java nor jaxws can manage NTLMv2 authentication.
http-client provides the authentication layer for me, and that is working
perfectly.
Now I have a new problem. When the servlet payload gets too large (and not all
that large, mind you) the input stream gets truncated and the Exchange EWS
request fails. Here are the details, see code below if needed:
The request.getContentLenght() method returns 9,219 bytes.
When I unload the request.getInputStream() into the buffer and count the bytes
the logger.debug spits out, I count 7,776 bytes. And indeed, the SOAP XML
package is malformed. What happened to the other 1,443 bytes?
App server=JBoss 5.1.
Anyone know what is going on and how to fix it?
Thanks,
Dave
