Java EE (Java Enterprise Edition) General Discussion

Hi All,

I am getting a IOException : bogus chunk size
java.io.IOException: Bogus chunk size
at sun.net.www.http.ChunkedInputStream.processRaw(ChunkedInputStream.java:292)
at sun.net.www.http.ChunkedInputStream.readAheadBlocking(ChunkedInputStream.java:545)
at sun.net.www.http.ChunkedInputStream.readAhead(ChunkedInputStream.java:582)
at sun.net.www.http.ChunkedInputStream.read(ChunkedInputStream.java:669)

My code does the following:
1) Open a httpURLConnection to a url and sends xml to create session.
2) Gets back a binary security token and builds an XML request for invoking a webservice.
3) Sends the request
4) I am getting IOException bogus chunk size here.

In what situations does one get bogus chunk size IOexception. Any comments/pointers are higly appreciated. I am pasting my code below .

Thank you.

Anand
