Couple of questions on Axis and web services

[Jade Jadaaih]

Hi all,

I have couple of questions and issues(all togather), which I got while I was exploring Apache Axis 1.4.

Before I go for the questions, let me confirm my understanding,
- Web services or services can be invoked or called by two ways one of them is by using the JAX-RPC way and other by SOAP. I was able to get the difference between them after couple of examples.
- Axis provides way for both of these implementations, however the Java2WSDL and WSDL2Java code creation tools are much inclined towards JAX-RPC based calls, rather than SOAP message based calls

Correct my understanding if I am wrong...I feel its to be corrected :-)

Now coming to my issues,

I am trying to implement a SOAP call to a service.The actual issue I am facing is, the request SOAP message goes to the server in full and it gets printed in tomcat console as full message. However, in the client I am able to get only partial message. I am unable to understand why its a problem.


Now my question is,

What is the difference between MessageContext objects getRequestMessage(), setRequestMessage(), getResponseMessage(), setResponseMessage() usage and Connection object's call method return in terms of response.

To explain better,
I am making a SOAP call in my client as follows,

SOAPMessage result = connection.call(message,new URL("http://localhost:8080/axis/services/echo")); 

and my Impl class is as follows,

import javax.xml.soap.SOAPMessage;
 
import org.apache.axis.Message;
import org.apache.axis.MessageContext;
 

public class EchoSoapBindingImpl implements com.sel.services.EchoMessage{
    public java.lang.Object echo() throws java.rmi.RemoteException {
    
    SOAPMessage message = null;
    try{
    MessageContext ctx = MessageContext.getCurrentContext();
    message = ctx.getRequestMessage();    
    ctx.setResponseMessage((Message)message); //Getting only half of the message in client when using this
//message.writeTo(System.out); //prints full message in tomcat console
    }catch(Exception e){
    e.printStackTrace();
    }finally{
    
    }
        return null;
    }
 
}

You may notice that, I am getting the request message from the MessageContext, so whats the need of passing the message object in call. In same way, I am returning a null in the Impl class but setting a response message in context, which I am able to get in client(partially). I am very much confused here

It would be great, if you could help me get answers for these questions and solve my confusions.


Thanks,
