Hi.

I'm trying to make a simple implementation of a webservice using document/literal and J2Me CLDC1.1 MIDP2.0

I've been using a combination of jbossws and suns wireless toolkit, but the errors are the same.

I used wstools to generate all the essential stuff.

The problem is I'm getting this exceptionn when running it on a device emulator included with the wtk:

java.rmi.MarshalException: (1)Missing end tag for Body or Envelope
 at com.stubs.TrivialService_Stub.purchase(+75)
 at com.apps.TestClient.startApp(+47)
 at javax.microedition.midlet.MIDletProxy.startApp(+7)
 at com.sun.midp.midlet.Scheduler.schedule(+270)
 at com.sun.midp.main.Main.runLocalClass(+28)
 at com.sun.midp.main.Main.main(+116)

I've verified the web service with a j2se client, runs smoothly without any hickups.


This is my simple MIDlet client:

package com.apps;

import java.rmi.RemoteException;

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
import javax.xml.rpc.Stub;

import com.stubs.TrivialService;
import com.stubs.TrivialService_Stub;

public class TestClient extends MIDlet {

 protected void startApp() throws MIDletStateChangeException {
 Form form = new Form("First test");
 form.append("HEllo Oinkers!");
 Display.getDisplay(this).setCurrent(form);


 TrivialService_Stub stub = new TrivialService_Stub();
 TrivialService ts = (TrivialService)stub;
 stub._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY, "http://10.0.102.112:8080/warme?wsdl");
 try {
 ts.purchase("Person","product");
 } catch (RemoteException e) {
 e.printStackTrace();

 }
 }

 protected void pauseApp() {
 // TODO Auto-generated method stub

 }

 protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

 }

}

and this is the stubs:

 throw new JAXRPCException("Stub does not recognize property: "+name);
 }

 }

}

I've also used a network monitor to intercept the data beeing sent over the wire:

the request:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://org.jboss.ws/samples/docstyle/wrapped/types">
 <soap:Body>
 <tns:purchase>
 <String_1 xmlns="">person</String_1>
 <String_2 xmlns="">product</String_2>
 </tns:purchase>
 </soap:Body>
</soap:Envelope>

and the response:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
 <env:Header/>
 <env:Body>
 <ns1:purchaseResponse xmlns:ns1='http://org.jboss.ws/samples/docstyle/wrapped/types' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
 <result>okPersonProduct</result>
 </ns1:purchaseResponse>
 </env:Body>
</env:Envelope>

hopefully someone can see whats wrong here..
