MarshalException: Missing end tag for body or Envelop

Question

Hi, I am new at this, pls advise.
I have been trying to code a 'hello world' that returns a string, as below.
//==================
package simple;
public class HelloWorld{
public String sayHello() {
return "hello";
//===================
and my buil.xml looks like this
//===================
<project name="simple" default ="all">
<property file="../properties.txt"/>
<property name="temp_dir" value="tmp_build" />
<target name="all" depends="clean,ear,deploy" />
<target name="clean" >
<delete dir="${classDir}/tutorial/simple" />
<delete file="${appDir}/simple.ear" />
<delete dir="${temp_dir}" />
<delete file="client.jar" />
</target>
<target name="build" depends="ear" />
<target name="ear" >
<delete dir="${temp_dir}" />
<mkdir dir="${temp_dir}" />
<mkdir dir="${temp_dir}/WEB-INF" />
<mkdir dir="${temp_dir}/WEB-INF/classes" />
<javac srcdir="." includes="HelloWorld.java"
destdir="${temp_dir}" />
<servicegen
destEar="simple.ear"
warName="simple.war"
contextURI="simple">
<service
javaClassComponents="simple.HelloWorld"
targetNamespace="http://examples/simple"
serviceName="Echo"
serviceURI="/HelloWorld"
     generateTypes="True"
expandMethods="True"
style="document">
<client
packageName="tutorial.simple.client"
clientJarName="client.jar"
/>
</service>
<classpath>
<pathelement path="${temp_dir}"/>
<pathelement path="${java.class.path}"/>
</classpath>
</servicegen>
</target>
<target name="deploy">
<copy file="simple.ear" todir="${appDir}"/>
</target>
</project>
//======================
I manage to deploy and run the service on weblogic through the browser. Next, when I try to run it on Java Wirelesss Tookit. I get a "MarshalException: Missing end tag for Body or Evelop" error.
I basically used the stub generator from WTK and use them as below
//====================
try {
String str = service.sayHello();
System.out.println( str );
} catch (Exception e) {
e.printStackTrace();
//=====================
I have no problem running other examples, just this one which i coded on my own. Can anyone pls enlightent me :)

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!
