Dynamics CRM 2011 Online WebServices from Java

Question

I'm trying to access MicroSoft Dynamic CRM 2011 online webservices from Java but no luck so far.

I got Organization WSDL file and generated required java stub files with the help of Axis2 (wsdl2Java).

And my simple client code is

public class TestCRM2 {

public static void main(String[] args) {

    try {   

        // create query
        QueryExpression query = new QueryExpression();
        query.setEntityName("Contact");

        ArrayOfstring colAra = new ArrayOfstring();
        colAra.addString("fullname");

        ColumnSet columnSet = new ColumnSet();
        columnSet.setAllColumns(false);
        columnSet.setColumns(colAra);

        PagingInfo pageinfo = new PagingInfo();
        pageinfo.setCount(10);
        pageinfo.setPageNumber(1);

        query.setColumnSet(columnSet);
        query.setPageInfo(pageinfo);            

        ConditionExpression condition = new ConditionExpression();
        condition.setAttributeName("fullname");
        condition.setOperator(ConditionOperator.Equal);

        ArrayOfanyType values = new ArrayOfanyType();
        values.setAnyType(new String[] {"something"});
        condition.setValues(values);

        RetrieveMultiple retrieveMultiple = new RetrieveMultiple();
        retrieveMultiple.setQuery(query);

        OrganizationServiceStub stub = new OrganizationServiceStub();           

        //set Timeout 
        ServiceClient serviceClient =  stub._getServiceClient();
        serviceClient.getOptions().setTimeOutInMilliSeconds( 3 * 60 * 1000);
        /*serviceClient.getOptions().setProperty(HTTPConstants.HTTP_PROTOCOL_VERSION, HTTPConstants.HEADER_PROTOCOL_10);
        serviceClient.getOptions().setProperty(HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED,false);*/         

        RetrieveMultipleResponse response = stub.retrieveMultiple(retrieveMultiple);            

        EntityCollection collection = response.getRetrieveMultipleResult();
        int count = collection.getTotalRecordCount();
        System.out.println(count);      

    } catch (Exception e) {
        e.printStackTrace();
    }
}}

When i run this from Eclipse, i get the following runtime error

Is there any thing I'm missing in my client code. Your help is highly appreciated.

You have to append "/web" at the end of your endpoint url in service client.
You will have to provide NTLM2 authenticator implementation and register it with httpclient used by your stub.

I've dealt with a few WCF services in the past but what is the /web extension? On a side note - the /web triggers the NTLM/Negotiate authentication mechanisms in the CRM Endpoint ... from there all I needed to do was configure my HttpClient for NTLM support. – Travis Sharp May 07 '13 at 21:51
