WS - "java.rmi.MarshalException: (1)Missing end tag for Body or Envelope"

Question

HI All,
I'm new of this forum but I really hope you could help me solving the problem I have to connect Web Services and midlets.
Somehow my configuration works with some services I've found online but when I invoke very simple services deployed on my server(s) I always have "java.rmi.MarshalException: (1)Missing end tag for Body or Envelope" exception"
Let me add some more information to the problem:
System Configuration:
- JBoss (but I also tried axis) - standard installation (http/1.1)
- WTK 2.5 (but I also tried 2.2) - standard installation
- I tried "trusted" and "untrusted" security configuration of the servlet
- Netbeans IDE 5.0 (to create both Midlets and WS)
- WS uses document/literal as expected by JSR 172
The midlet is created with no problems but at the time of invocation the server throws the above exception (which is part of rmi. remoteException)
By monitoring the network both at client and server side I noticed that the information received is chuncked after 768 bytes. However, If the (soap) reponse is less than such value, I still have the error.
Using Http/1.1. at the mobile side, the service does not return me anything (0kb) while if I set the mobile device to http/1.0, I get the above error.
I really have to make the midlet running so any type of help will be really appreciated!!
Thanks in advance

Hi all,
as many developers I have encountered the famous "java.rmi.MarshallException:(1)Missing end tag for Body or Envelope" during the development of my WS app for J2ME (JSR 172).
It is correct that is the empty tag <soapenv:Header /> causing this error.
To fix this error, it is necessary to stop the server to generate this empty header in the response stream.
I have fixed this error for Axis2: unfortunaly it is necessary to modify a class in Axiom library. This library is used in Axis2 to produce the SOAP response, you can download the source code at http://ws.apache.org/commons/axiom/source-repository.html.
Here the class to modify:
axiom\modules\axiom-impl\src\main\java\org\apache\axiom\soap\impl\llom\soap11\SOAP11Factory.java
by commenting the line 273 in the method called getDefaultEnvelope() to prevent the empty header insertion in SOAP response:
public SOAPEnvelope getDefaultEnvelope() throws SOAPProcessingException {
        OMNamespace ns =
                new OMNamespaceImpl(
                        SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI,
                        SOAP11Constants.SOAP_DEFAULT_NAMESPACE_PREFIX);
        SOAPEnvelopeImpl env = new SOAPEnvelopeImpl(ns, this);
        //createSOAPHeader(env); the line to be commented
        createSOAPBody(env);
        return env;
    }Finally you have to recompile Axiom using Maven to obtain the fixed package axiom-impl.jar and to replace this package on the lib repository of your Axis2 server.
A little tricky to fix this bug but now my app runs perfectly ;)
Enjoy!
