I am using APache soap v2 API , here is the piece of code

I got exception - need deseriablizer for a "salesforec:map"

Could you help me out

String endPointURL = "http://www.salesforce.com/servlet/servlet.SoapApi";

//build soap call object
String encodingStyleURI = Constants.NS_URI_SOAP_ENC; //should get from propperties
try {
url = new URL(endPointURL);
}
catch (Exception e){};

System.out.println("url "+url);
SOAPMappingRegistry smr = new SOAPMappingRegistry ();
//MapSerializer sd = new MapSerializer ();
MapEntrySerializer sd = new MapEntrySerializer ();

smr.mapTypes (Constants.NS_URI_SOAP_ENC,
new QName ("", "return"),MapEntry.class, sd, sd);


// Build the call.
Call call = new Call();

call.setTargetObjectURI("sfconnector:SalesforceConnector");
call.setMethodName("login");
call.setEncodingStyleURI(encodingStyleURI);
call.setSOAPMappingRegistry (smr);


Vector params = new Vector();
params.addElement(new Parameter("version", String.class,
"1.9", null));
params.addElement(new Parameter("username", String.class,
"rthurston@aptsoft.com", null));
params.addElement(new Parameter("password", String.class,
"Aptsoft", null));
params.addElement(new Parameter("secure", java.lang.Boolean.class,
(Boolean)(new Boolean(false)),null));
params.addElement(new Parameter("remoteApplication", String.class,
"myApp", null));


call.setParams(params);
System.out.println("params set "+call.toString());


// Invoke the call.
Response resp;
try {
resp = call.invoke(url, "");
MapEntry me = (MapEntry)resp.getReturnValue().getValue();
String sid = (String)me.getValue();
}
catch (SOAPException e){
System.out.println("Caught SOAPException (" +
e.getFaultCode() + "): " +
e.getMessage());
return false;
}

// Check the response.
if (!resp.generatedFault()) {
return true;

}
else {

Fault fault = resp.getFault();

System.out.println("Generated fault: ");
System.out.println(" Fault Code = " + fault.getFaultCode());
System.out.println(" Fault String = " + fault.getFaultString());
return true;

}
