Connecting to Analysis Services with Java XML

I know this has been posted before but I cannot seem to find an answer to
my problem. Basically I am having trouble with the connection string in
"DataSourceInfo". I get the error:

XA:XMLAnalysisError.88BA0500
Unable to process the request, because the DataSourceInfo property was
missing or not correctly specified

I can get the VB sample to work no problem but for some reason I just
cannot get Java to work. I know I should not be using hard-coded
parameters but I am just trying to get it to work and they are the same I
am using in the VB example.

My Java code is:

im****t java.net.*;
im****t java.util.*;
im****t org.apache.soap.*;
im****t org.apache.soap.rpc.*;
im****t org.apache.soap.encoding.*;
im****t org.apache.soap.encoding.soapenc.*; im****t
org.apache.soap.util.xml.*;
im****t org.apache.soap.trans****t.http.*;

public class Client {

    public static void main( String[] args ) throws Exception {
        
        URL url = new URL("http://192.168.2.106/xmla/msxisapi.dll";
                
        SOAPMappingRegistry smr = new SOAPMappingRegistry();
        StringDeserializer sd = new StringDeserializer();
	smr.mapTypes(Constants.NS_URI_SOAP_ENC,
			new QName("","Result"), null, null, sd);

        SOAPHTTPConnection st = new SOAPHTTPConnection();

        Call call = new Call();
        call.setSOAPTrans****t(st);
        call.setSOAPMappingRegistry(smr);

        call.setTargetObjectURI
        ("urn:schemas-microsoft-com:xml-analysis");
        call.setMethodName("Discover");
       
call.setEncodingStyleURI("http://schemas.xmlsoap.org/soap/encoding/");

        Vector params = new Vector();
        
        params.addElement(new Parameter("RequestType",String.class,
        					"MDSCHEMA_CUBES", null));

        params.addElement(new Parameter("Restrictions",String.class,
                "<RestrictionList>" +
                    "<DataSourceName>" +
                        "Local Analysis Server" +
                    "</DataSourceName>" +

                    "<CATALOG_NAME>" +
                        "FoodMart" +
                    "</CATALOG_NAME>" +
                "</RestrictionList>", null ));
                
        params.addElement(new Parameter("Properties",String.class,
                "<PropertyList>" +
                    "<DataSourceInfo>" +
                        "Data Source=server1;Provider=MSOLAP.2" +
                    "</DataSourceInfo>" +
                
                    "<Catalog>" +
                        "Foodmart" +
                    "</Catalog>" +
                "</PropertyList>", null ));
      
      
        call.setParams(params);
        call.buildEnvelope();

        System.out.println("Request="+call.toString()+"\n");

        Response resp = null;
        try {
            resp = call.invoke (url,
            	   "urn:schemas-microsoft-com:xml-analysis:Discover");
        }
        catch (SOAPException e) {
            System.err.println("Caught SOAPException(" + 
				e.getFaultCode() + "): " + 
				e.getMessage ());
	    return;
        }
        
        if (resp != null && !resp.generatedFault()) {
            Parameter ret = resp.getReturnValue();
	    Object value = ret.getValue();
            
            System.out.println("Answer="+value);
        }
        else {
            Fault fault = resp.getFault();
            System.out.println("Generated Fault:");
            System.out.println("Fault code = "+fault.getFaultCode());
            System.out.println("Fault string = "+fault.getFaultString());
        }
    }
}

Anyone any ideas?
 
Thanks.
