Java Web Service Client
I'm trying to write a Java client to connect to a web service using Axis 1.4 (choose this by default, perhaps I should use something else?). The web service has a URL of the form "http://domain.com/directory/service.asmx" and I'm trying to call a method of the form MethodName(String stateAbbr). I get an error saying that I'm not providing the parameter, my code is below:
String stateAbbrev = "Tx";
String endpoint = "http://domain.com/directory/service.asmx";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new URL(endpoint));
call.setSOAPActionURI("MYSOAPACTIONURI");
call.setOperationName(new QName(URI, MethodName));
call.addParameter("stateAbbr", XMLType.XSD_STRING, ParameterMode.IN);
call.setReturnType(XMLType.XSD_ANY);
call.invoke(new Object[] {stateAbbrev});

I guess that I'm trying to send an envelope. The only instruction I have is that the request is supposed to look like this:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<METHODNAME xmlns="TARGETNAMESPACE">
<PARAMETER>string</PARAMETER>
<PARAMETER2>string</PARAMETER2>
</METHODNAME>
</soap:Body>
</soap:Envelope>
I tried the following code to build the soap envelop directly but I had the same error with it:
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setSOAPActionURI(targetNameSpace + operationName);
call.setUseSOAPAction(true);
call.setOperationName(new QName(targetNameSpace, operationName));
SOAPEnvelope envelope = new SOAPEnvelope();
SOAPBody body = envelope.getBody();
SOAPElement methodElement = body.addChildElement( envelope.createName(operationName, null, targetNameSpace));
SOAPElement countyElement = methodElement.addChildElement( "PARAMETER" );
countyElement.addTextNode(PARAMETERValue);
SOAPElement stateElement = methodElement.addChildElement( "PARAMETER2" );
stateElement.addTextNode(PARAMETER2Value);
SOAPEnvelope responseEnvelope = call.invoke(envelope);
Ultimately I was able to write code using a HttpURLConnection to directly post data to the web service and read the response, however I'm still curious how you'd do this with the SOAP stuff.

try the following:
ServiceClient client = new ServiceClient();
OperationClient operationClient = client.createClient(ServiceClient.ANON_OUT_IN_OP);
MessageContext outMsgCtx = new MessageContext();
Options opts = outMsgCtx.getOptions();
opts.setTo(new EndpointReference(endpoint);
opts.setAction(action);
outMsgCtx.setEnvelope(yourEnvelope);
operationClient.addMessageContext(outMsgCtx);
operationClient.execute(true);
MessageContext inMsgtCtx = operationClient.getMessageContext("In");
SOAPEnvelope response = inMsgtCtx.getEnvelope();
System.out.println(response);
