>          URL: http://issues.apache.org/jira/browse/AXIS-1781
>      Project: Axis
>         Type: Bug
>   Components: WSDL processing
>     Versions: 1.1
>  Environment: Windows XP SP1, Tomcat 5, Sun WTK 2.1, Axis 1.1, J2ME, JSR-172
>     Reporter: Paul Meier
>  Attachments: WSTest WTKProject.rar, hallo.class, hallo.jws, hallo.wsdl

> Hallo,
> I'm a beginner to webservices with Apache Axis. For a project with J2ME that should use
webservice functions I wanted to test an little webservice with Axis and the Sun WTK 2.1.
> The name of the test class is hallo.java and was renamed to hallo.jws and placed in the
webapps\axis folder of Tomcat.
> It contains following code: 
> public class hallo {
> 	public int hallo2(String input, int i) {
> 	System.out.println("input " + input + " " + i);
>  	return (i);
> 	}
> } 
> Nothing special as you see. The testing of this service in a java client on pc worked
fine, after creating the needed stubs of course. 
> To generate the doc/lit style WSDL file for the Sun WTK 2.1 stub generator I used folowing
command  
> java -cp ".\axis.jar;.\commons-logging.jar;.\commons-discovery.jar;.\saaj.jar;.\wsdl4j.jar;.\jaxrpc.jar;."
org.apache.axis.wsdl.Java2WSDL -l "http://localhost:8080/axis/hallo.jws" -y WRAPPED -u LITERAL
hallo
> That worked fine and the wsdl file with following content was created: 
> <?xml version="1.0" encoding="UTF-8"?>

> The stub generation generated the needed stubs for the midlet, but 2 errors occured:

> warning: R2716 WSI-BasicProfile ver. 1.0, namespace attribute not allowed in doc/lit
for soapbind:body: "hallo2"
> warning: R2716 WSI-BasicProfile ver. 1.0, namespace attribute not allowed in doc/lit
for soapbind:body: "hallo2"
> The deletion of " namespace="http://DefaultNamespace" " in the wsdl file led to stub
generation of "hallostub" in src folder without am error message.
> The midlet source WSTest.java is almost the same like the example of AxisUserTest last
year. The only changes are the 
> import of the hallostub package, the creation of an object of class Hallo named hallo
and initialized with hallo = new Hallo_Stub(); and the function call 
> int result = hallo.hallo2("GoodMorning!", 6);
> System.out.println("Ergebnis: " + result);
> String text = "Result is " + result + ".";
> Alert a = new Alert("Result", text, null, AlertType.CONFIRMATION); .
> The compilation and packaging (with j2me-ws.jar in lib) worked fine but in neither the
SUN emulator or other emulators like Siemens CX65 or Nokia S40 or S60, the response to the
webservice could be received.  
> For instance the Sun emulator sais after calling the service:
> java.rmi.MarshalException: Invalid Element in Response: hallo2Return
> 	at hallostub.Hallo_Stub.hallo2(+82)
> 	at WSTest.run(+13)
> The tomcat output windows shows after calling the service: 
> input GoodMorning! 6 
> I conclude that the webservice has been called correctly, but the answer can not be understood
by the midlet. 
> How can this be solved?
> Thank you very much for your help.
> Paul
