How to pass complex type parameter in web service while creating it through SAAJ

[Sachin Mangla]

Hi friends,

I am developing one webservice through SAAJ. I want to know, is the request and response are SOAP message or not? But i donot know how to pass the complex type parameter through SAAJ. Below is the code that i am using.

import goog.*;
import javax.xml.soap.*;
import java.net.*;
import javax.activation.*;
public class RmiTypeClient extends goog.Pressures{
public RmiTypeClient(String value){
super(value);
}
public static void main(String args[]){
try{
RmiTypeClient r1 = new RmiTypeClient("gramPressurePersqcm");
RmiTypeClient r2 = new RmiTypeClient("inchH2O60F");

MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();

SOAPBody body = message.getSOAPBody();

SOAPFactory soapFactory = SOAPFactory.newInstance();
Name operation = soapFactory.createName("changePressureUnit","webservicex","http://www.webservicex.net"); //changePressureUnit is the method name

SOAPBodyElement operElement = body.addBodyElement(operation);
Name param1 = soapFactory.createName("param1");
SOAPElement paramElement1 = operElement.addChildElement(param1);
paramElement1.addTextNode("12.0"); // this is first parameter

Name param2 = soapFactory.createName("param2");
SOAPElement paramElement2 = operElement.addChildElement(param2);
paramElement2.addTextNode("r1"); // this is second parameter, r1 is the complex type parameter of "RmiTypeClient" class. but i donot know how to pass it here??

Name param3 = soapFactory.createName("param3");
SOAPElement paramElement3 = operElement.addChildElement(param3);
paramElement3.addTextNode("r2"); // this is third parameter, r2 is the complex type parameter of "RmiTypeClient" class, but i donot know how to pass it here??

SOAPConnectionFactory conFactory = SOAPConnectionFactory.newInstance();
SOAPConnection con = conFactory.createConnection();

URL serviceUrl = new URL("http://www.webservicex.net/CovertPressure.asmx?WSDL");

SOAPMessage response = con.call(message,serviceUrl);
SOAPBody resBody = response.getSOAPBody();
if(resBody.hasFault()){
SOAPFault fault = resBody.getFault();
System.out.println("Error occured at: "+fault.getFaultCode()+ " side coding");
System.out.println("reason: "+fault.getFaultString());
}else{
System.out.println("this is soap message");
}
}catch(Exception e){
System.out.println(e);
}
}
}

Please help me to resolve it.
Thanks in advance.

1. Basically, I play with APACHE CXF to generate Client/Consumer side and TCPIP monitor to watch the request SOAP Message.
2. The SOAP message is

SOAP 1.1 Message

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ChangePressureUnit xmlns="http://www.webserviceX.NET/">
<PressureValue>0.08162684277911048</PressureValue>
<fromPressureUnit>kgfPersquaremeter</fromPressureUnit>
<toPressureUnit>poundalPersqfoot</toPressureUnit>
</ChangePressureUnit>
</soap:Body>
</soap:Envelope>


SOAP 1.2 Message

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Body>
<ChangePressureUnit xmlns="http://www.webserviceX.NET/">
<PressureValue>0.9646785853371228</PressureValue>
<fromPressureUnit>lbfPersquarefoot</fromPressureUnit>
<toPressureUnit>poundalPersqfoot</toPressureUnit>
</ChangePressureUnit>
</soap:Body>
</soap:Envelope>

3. What you need to create/code is the ChangePressureUnit Element (complex type).
Add this ChangePressureUnit Element to the soap Body Element. Hope this help.

<ChangePressureUnit xmlns="http://www.webserviceX.NET/">
<PressureValue>0.9646785853371228</PressureValue>
<fromPressureUnit>lbfPersquarefoot</fromPressureUnit>
<toPressureUnit>poundalPersqfoot</toPressureUnit>
</ChangePressureUnit>

Paul,
Thanks for the reply. But I am using axis2 at client/consume services.
I tried to check the request with TCP Tunnel, but it requires a port to whom it diverts from there port, which is not feasible in my case.

I also tried the case that you defined but not working, i make the request this way:

SOAPBodyElement operElement = body.addBodyElement(operation);
Name param1 = soapFactory.createName("PressureValue");
SOAPElement paramElement1 = operElement.addChildElement(param1);
paramElement1.addTextNode("12.0");

Name param2 = soapFactory.createName("fromPressureUnit");
SOAPElement paramElement2 = operElement.addChildElement(param2);
paramElement2.addTextNode("gramPressurePersqcm"); // i changed value here, but i donot understand that "changePressureUnit" method requires object of RmiTypeClient class, how it will treats this value as object

Name param3 = soapFactory.createName("toPressureUnit");
SOAPElement paramElement3 = operElement.addChildElement(param3);
paramElement3.addTextNode("inchH2O60F"); // same case here

it always give me this error:

Error occured at: Client side coding
reason: System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: .
at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest()
at System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message)
at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

Please suggest some other option which helps with axis2.

Thanks in advance

I set TCP/IP Monitor:

1. Local Monitoring port: 18080
2. Monitor
Hostname www.webservicex.net
Port 80
Type HTTP
3. String targetEndPoint="http://localhost:18080/CovertPressure.asmx";
This way I see the request soap message going out from the client side.

To solve the exception "Server did not recognize the value of HTTP Header SOAPAction"

From http://www.webservicex.net/CovertPressure.asmx?WSDL, there is an soapAction

  <soap:operation soapAction="http://www.webserviceX.NET/ChangePressureUnit" style="document" /> 

So you need to set the HTTP Header SOAPAction to http://www.webserviceX.NET/ChangePressureUnit

			SOAPMessage sOAPRequestMessage=messageFactory.createMessage();
			
			MimeHeaders mimeHeaders = sOAPRequestMessage.getMimeHeaders();
			String uri = "http://www.webserviceX.NET";
			mimeHeaders.setHeader("SOAPAction", uri+ "/ChangePressureUnit");

1. Here is a way to create ChangePressureUnit Element

			// BEGIN
			SOAPBody sOAPBody  =sOAPRequestMessage.getSOAPBody();			
			QName changePressureUnit = new QName("http://www.webserviceX.NET/", "ChangePressureUnit");
			SOAPBodyElement changePressureUnitSOAPBodyElement = sOAPBody.addBodyElement(changePressureUnit);
	
			SOAPFactory sOAPFactory=SOAPFactory.newInstance();			
			SOAPElement pressureValueSOAPElement= sOAPFactory.createElement("PressureValue");
			pressureValueSOAPElement.addTextNode("0.9646785853371228");
			
			SOAPElement fromPressureUnitNameSOAPElement= sOAPFactory.createElement("fromPressureUnit");
			fromPressureUnitNameSOAPElement.addTextNode("lbfPersquarefoot");			
			
			SOAPElement toPressureUnitSOAPElement= sOAPFactory.createElement("toPressureUnit");
			toPressureUnitSOAPElement.addTextNode("poundalPersqfoot");
			
			changePressureUnitSOAPBodyElement.addChildElement(pressureValueSOAPElement);
			changePressureUnitSOAPBodyElement.addChildElement(fromPressureUnitNameSOAPElement);
			changePressureUnitSOAPBodyElement.addChildElement(toPressureUnitSOAPElement);
			
			sOAPRequestMessage.writeTo(System.out);
			// END
