[jboss-user] [Beginners Corner] - Help in Setting up Servlet which receives/sends SOAP request

[helgravis]

Hi, I'm fairly new in JBoss and I was wondering how to properly implement a JAXMServlet.

Basically I needed a servlet which receives SOAP messages which is then passed to some EJBs.

Here's my code, compiled with jaxm-api.jar and jboss-saaj.jar. The servlet just receives a soap message, prints it out, and replies with a dummy soap message:

anonymous wrote : package com.app;
  | 
  | import javax.servlet.ServletConfig;
  | import javax.servlet.ServletException;
  | import javax.xml.messaging.JAXMServlet;
  | import javax.xml.messaging.ReqRespListener;
  | import javax.xml.soap.*;
  | 
  | public class SOAPServlet extends JAXMServlet implements ReqRespListener
  | {
  | 	public SOAPServlet()
  | 	{
  | 	}
  | 	
  | 	public void init(ServletConfig config) throws ServletException
  | 	{
  | 		super.init(config);
  | 	}
  | 	
  | 	public void destroy() {}
  | 	
  | 	public String getServletInfo()
  | 	{
  | 		return null;
  | 	}
  | 	
  | 	public javax.xml.soap.SOAPMessage onMessage(javax.xml.soap.SOAPMessage sOAPMessage) 
  | 	{
  | 	
  | 		System.out.println("Got a SOAP: "+sOAPMessage);
  | 		
  | 		SOAPMessage message = null;
  | 		
  | 		try
  | 		{
  | 			MessageFactory factory = MessageFactory.newInstance();
  | 			message = factory.createMessage();
  | 			SOAPPart soapPart = message.getSOAPPart();
  | 			SOAPEnvelope envelope = soapPart.getEnvelope();
  | 			SOAPBody body = envelope.getBody();
  | 			Name bodyName = envelope.createName("Response");
  | 	
  | 			SOAPBodyElement gltp = body.addBodyElement(bodyName);
  | 			Name nof = envelope.createName("blah");
  | 			
  | 			SOAPElement fileNumber = gltp.addChildElement(nof);
  | 			fileNumber.addTextNode("123");
  | 		}
  | 		catch(Exception e)
  | 		{
  | 			System.out.println(e);
  | 		}
  | 		
  | 		System.out.println("Returning message: "+message);
  | 		
  | 		return message;
  | 	}
  | }

It compiles fine. But when I deployed it, it fired an error saying it couldn't find javax.xml.messaging.ReqRespListener. I assumed that the current filepath isn't finding the right classes, so what I did is dump the jaxm-api.jar in the jbosshome/lib/endorsed folder. It filed an error saying it couldn't find HttpServlet, so I added servlet-api.jar as well. Now the servlet deploys fine.

But whenever I try to send a SOAP using a SOAPClient, the servlet fires an error saying:

Here's the SOAPClient code:

anonymous wrote : package com.app;
  | 
  | import javax.xml.soap.*;
  | 
  | import java.net.URL;
  | 
  | public class SOAPsender 
  | {
  | 	public static void main(String[] args)  
  | 	{
  | 		try 
  | 		{			       
  | 			SOAPConnectionFactory soapConnectionFactory =
  | 			SOAPConnectionFactory.newInstance();
  | 			SOAPConnection connection = soapConnectionFactory.createConnection();
  | 			SOAPFactory soapFactory = SOAPFactory.newInstance();
  | 
  | 			MessageFactory factory =
  | 			MessageFactory.newInstance();
  | 			SOAPMessage message = factory.createMessage();
  | 
  | 			SOAPHeader header = message.getSOAPHeader();
  | 			SOAPBody body = message.getSOAPBody();
  | 			header.detachNode();
  | 
  | 			Name bodyName = soapFactory.createName("asd");
  | 			SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
  | 
  | 		    Name name = soapFactory.createName("symbol");
  | 		    SOAPElement symbol = bodyElement.addChildElement(name);
  | 		    symbol.addTextNode("SUNW");
  | 
  | 		    URL endpoint = new URL ("http://localhost:8080/SOAPServlet/soap");
  | 		    SOAPMessage response = connection.call(message, endpoint);
  | 
  | 		    connection.close();
  | 
  | 		    SOAPBody soapBody = response.getSOAPBody();
  | 
  | 			System.out.println(soapBody);
  | 		} 
  | 		catch (Exception ex) 
  | 		{
  | 			ex.printStackTrace();
  | 		}
  | 	}
  | } 
  | 

Please, can anyone tell me what I'm doing wrong? An asap reply is very much appreciated, or maybe just a simple working .war example with all the necessary jars packed in it?

I'm using jboss4.2.0, by the way.

Thank you very much
