RE: 'Socket closed' exception using

[Preygel, Sofya]

Here it is:
      PostMethod post = new PostMethod(m_URL);
      post.setHttp11(false);
      post.setRequestHeader("Content-Length",
Integer.toString(payload.toString().length()));
      post.setRequestHeader("Content-type", "text/xml;charset=utf-8");
      post.setRequestHeader("Content-type", "text/xml;
charset=ISO-8859-1");
      post.setRequestHeader("SOAPAction",
"http://tempuri.org/action/Agent."; + action);
      post.setRequestContentLength(payload.toString().length());
      post.setRequestBody(payload.toString());
 
I tried to also use "keep-alive" connection option (even though I know
it makes little sense for HTTP 1.0), but to no avail.
 
Thanks,
Sofya

        How are you setting your headers?  That is sometimes the issue
on socket closings.

                Hello,
                
                We are trying to use HTTPClient.execute(PostMethod) for
sending SOAP
                requests to Connotate's Web Mining Server (WMS). The
requests are sent
                every 1 minute, and in most cases everything works fine.
However, every
                so often (sometimes way too often!) we are getting the
'Socket closed'
                exception. The socket timeout was initially set to 10
seconds (10000
                millis), but even after I set it to 120 seconds (120000
millis), we are
                still seeing it happening quite often. I tried to use
both the
                getResponseBodyAsString() and getResponseBodyAsStream()
to retrieve the
                response, but it does not change anything.
                
                The application is running on Windows 2000 (SP4). I
tried both the
                HTTPClient v2.0 (final) and the latest night build (as
of yesterday),
                but the results are the same. We are using HTTP 1.0
                (PostMethod.setHttp11(false)), with the application
running on the same
                computer as the WMS.
                
                I will appreciate any suggestions about what can be done
here.
                
                Thank you,
                Sofya
