Problem with 'httpChunkStream = true' through VPN

Hi all,

I am using Axis to call webservices storing business objects in
Microsoft CRM (works great!!!). I've been developing and calling
webservices on a server running local on top of vmware. Now I am trying
to call my colleagues development server which I can access through a
VPN tunnel ... But it fails. I get the following exception:

java.net.SocketException: Connection reset

Cool, so I started digging and found that I don't get this exception
when setting 'httpChunkStream = false'. This is the testcode:
        HttpClient httpClient = new HttpClient();
        Credentials credentials = new NTCredentials("user",
                "pwd",
                "localhost",
                "domain");
        httpClient.getState().setCredentials(AuthScope.ANY,
credentials);
        HttpMethodBase method = new
PostMethod("http://localhost/mscrmservices/2006/crmservice.asmx");
        Message reqMessage = new Message("test");
        ((PostMethod)method).setRequestEntity(new
MessageRequestEntity(method, reqMessage, false));

        try {
            int returnCode = httpClient.executeMethod(method);
            String response = method.getResponseBodyAsString();
            System.out.println("Response: " + response);
        } catch (HttpException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

How to propagate this property to Axis (I'm using the stub generated by
wsdl2java).

Thanks.


Regards,

Kenneth

Good Morning Ken-

good news you have been able to determine the workaround..
for configuring the chunking capability you will need to set the HTTP transport version back to 1.0

 Service service = new Service(); //A new axis Service.
 Call call = (Call) service.createCall(); //Create a call to the service.

        /*Un comment the below statement to do HTTP/1.1 protocol (to enable chunking..)*/
        //call.setScopedProperty(MessageContext.HTTP_TRANSPORT_VERSION,HTTPConstants.HEADER_PROTOCOL_V11);
        //Hashtable myhttp = new Hashtable();
        //myhttp.put("dddd", "yyy");     //Send extra soap headers
        //myhttp.put("SOAPAction", "dyyy");
        //myhttp.put("SOAPActions", "prova");
        /*Un comment the below to do http chunking to avoid the need to calculate content-length. (Needs HTTP/1.1)*/
        //myhttp.put(HTTPConstants.HEADER_TRANSFER_ENCODING, HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED);

//this option will disable chunking..
call.setScopedProperty(MessageContext.HTTP_TRANSPOR_VERSION,HttpConstants.HEADER_PROTOCOL_V10);

HTH
