Below please find the source code and reuntime results that demonstrates the
problem I'm having.
This is not my actual application but what I'm doing is essentially the same
thing.
WEB SERVICE CODE
----------------
package ws.pojo.data;
public class WSDataOnlyObj
{
public String str = "This is a data only object";
public int num = 1;
}
package ws.pojo.service;
import ws.pojo.data.*;
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
-----------
package ws.pojo.service;
import ws.pojo.data.*;
import java.rmi.RemoteException;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.*;
import org.apache.axis2.client.*;
import org.apache.axis2.rpc.client.*;
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

For the web services application I am developing I have designed my web
services methods to accept objects and return objects. To avoid any problems
and follow "best practices" for web development I have designed these objects
with only "primitives" as attributes for objects that are passed and returned.
There is no requirement to use only primitives. you can use objects but those
objects should be POJOs.
The stub code generated by Axis2 appears to provide everything needed to
get and set the attributed for these objects. I have tried several of my web
service methods from a test client using the Axis2 generated client stub. I am
able to set the attributes of all passed objects and retrieve the attributes of
all returned objects, but in both cases the attributes have no values!!!!
Can you send your wsdl and request and response message xmls?
I have debugged the code on both the server and client side to make sure
the values were being set correctly going both ways, and they are. It is as if
when the objects are serialized and deserialized from client to server or
server to client the attribute values of the passed and returned objects are
being lost.
Can anyone explain?
Thanks,
Mike
