Hi,

I am using two jsp pages:
one(send.jsp) sends SAMLRequest to other (receive.jsp) which responds with a
SAMLResponse.

This is piece of code i use..
I am using SAMLSoapBinding.

send.jsp contains:
...

..
resp = binding.send(authBinding,req);
...



receive.jsp contains:

....

response.reset();
binding.respond(response,resp,null);
....


An IOException is thrown from receive.jsp in method respond().
The problem seems to be that an outputstram is already opened by the server
but i am not sure.

Can anybody help me ?
I have given the logs below.

Thanks in advance.
