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 .html>javax.xml.soap.SOAPMessage javax.xml.soap.SOAPMessage .java.html>' border=0> onMessage(javax.xml.soap.SOAPMessage .html>javax.xml.soap.SOAPMessage javax.xml.soap.SOAPMessage .java.html>' border=0>
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:

|
| 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
