Deepal,

Thank you.  I will look at both right now.

Hi Michael
I would suggest you to read following articles, then you can get better
idea about Axis2 service and how to invoke them.

to understand POJO in axis2 :- http://wso2.org/library/2893
To understand Axis2 client side :-
http://today.java.net/pub/a/today/2006/12/13/invoking-web-services-using-apache-axis2.html
OK.  Is it me?  I know I'm 1) not understanding Axis2's API and
therefore 2) not using it correctly.

For the past three weeks I have been unable to get anything but the
simplist web service to work.  By simplest I mean a web service that
passes and returns only primitives (i.e. int, float, String,
etc....).  I have been following the examples I found on the web
(bottom-up web services with Axis2) and on the Apache Axis2 web site (
bottom-up development web services with Axis2 and POJO's).  Here is
some of what I've tried.  Can anyone tell me what I'm missing?

Bottom-Up Web Service Using Java Objects As Parameters And/Or Return
Values
public class WSDataOnlyObj
{
 public String str = "This is a data only object";
 public int    num = 1;
}



public class WS
{
 private String          str;
 private WSDataOnlyObj   objDataOnly;

 public String GetString( )
 {
  str = "This is a string";

  return str;
 }

 public WSDataOnlyObj GetDataOnlyObj( )
 {
  objDataOnly = new WSDataOnlyObj( );
  return objDataOnly;
 }
}



CLIENT CODE
-----------
import java.rmi.RemoteException;
import org.apache.axis2.AxisFault;

public class WSClient
{
 public static void main(String[] args)
 {
  try
  {
   WSStub.GetStringResponse      getStringResp;
   WSStub.GetDataOnlyObjResponse getDOObjResp;

   WSStub stub = new
WSStub("http://localhost:8080/Webservice/services/WS/ws/pojo/service";);

   getStringResp = stub.GetString();
   getDOObjResp  = stub.GetDataOnlyObj();

   System.out.println("RESULT Of Call To Web Service GetSting(): " +
                                getStringResp.get_return());
   System.out.println("RESULT Of Call To Web Service
GetDataOnlyObj().getStr(): " +
                               getDOObjResp.get_return().getStr());
   System.out.println("RESULT Of Call To Web Service
GetDataOnlyObj().getNum(): " +
                               getDOObjResp.get_return().getNum());
  }
  catch(AxisFault axisEx)
  {
   System.out.println(axisEx.getMessage());
  }
  catch(RemoteException remEx)
  {
   System.out.println(remEx.getMessage());
  }
 }
}



RESULTS
-------
RESULT Of Call To Web Service GetSting(): This is a string
RESULT Of Call To Web Service GetDataOnlyObj().getStr(): null
RESULT Of Call To Web Service GetDataOnlyObj().getNum(): -2147483648
You see!!!!  Getting the String return value works fine with this
method but not getting the object return value.
Now let's look at trying the POJO example given in the Axis2
documentation.

Bottom-Up Web Service Using Java Objects As Parameters And/Or Return
Values - POJO Client Example
public class WSDataOnlyObj
{
 private String str = "This is a data only object";
 public String GetString( )
 {
  return str;
 }

 public void SetString(String aStr)
 {
  str = aStr;
 }
}



public class WS
{
 public WSDataOnlyObj GetDataOnlyObj( )
 {
  WSDataOnlyObj objDataOnly = new WSDataOnlyObj( );
  return objDataOnly;
 }
}

import javax.xml.namespace.QName;

import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
public class WSTestClientApp
{
 public static void main(String[] args)
 {
  try
  {
   RPCServiceClient serviceClient = new RPCServiceClient( );

   Options options = serviceClient.getOptions( );

   EndpointReference epr = new
EndpointReference("http://localhost:8080/WSTest/services/WS";);

   options.setTo(epr);

   Object[ ] opWSDataOnlyObjArgs = new Object [ ] { };
   Class [ ] returnTypes = new Class [ ] {WSDataOnlyObj.class};

   .....
  }
  catch(AxisFault axisEx)
  {
   System.out.println(axisEx.getMessage());
  }
  catch(RemoteException remEx)
  {
   System.out.println(remEx.getMessage());
  }
 }
}

Here's my problem with this example, this code (adapted from the
"weather" example) requires an import of the package containing the
WSDataOnlyObj.  You can make this work for this example but unless I'm
wrong the client should get all objects from the stub and should not
have to access the development package of the web service object!!!!!

These appear to be some serious problems with the Axis2 API.

Can anyone explain what I might be missing?

Thanks
