jsr172 problem: can't decode the received response package

[jason_rency]

all,
I am trying to invoke a webservice from a j2me client.
I am using wtk 2.2 generate the stub code and using sun j2me webservice jar which implements jsr172.

I found that the j2me client couldn't decode the received response package properly:

javax.xml.rpc.JAXRPCException: java.rmi.MarshalException: (1)Missing end tag for Body or Envelope
	at com.sun.j2mews.xml.rpc.SOAPDecoder.decode(+243)
	at com.sun.j2mews.xml.rpc.OperationImpl.invoke(+90)
	at service.Calculator_Stub.add(+62)

the response package I got is:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
<env:Header/>
	<env:Body>
		<ns1:addResponse xmlns:ns1='http://server.reg.src/jaws' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
			<ns1:result>10</ns1:result>
		</ns1:addResponse>
	</env:Body>
</env:Envelope>

anything wrong with the package?

apparantly I can't trace further because I don't have the jsr172 RI source code.

Just a thought. Have you tried with having both the begin and end tags for env:Header (instead of the combined tag)?

Hartti

[jason_rency]

that's a good thought and I would try?

very stupid question, how can I reformat the response message in the server side?

thanks a lot..

[jason_rency]

also, the response is missing <?xml version="1.0" encoding="UTF-8"?>

is this a matter?

Hi jason_rency,

Just a tip. Have you tried Carbide.j's JME Web Services Client Tool? Give it a try and compare the results...

hi Juarez,

I tried webservice client too from Carbide, and the generate stub tried to user Integer for int,
I then used the generated stub to test the web service got a 500 internal error and the response is:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
<env:Header/>
     <env:Body>
        <env:Fault> 
            <faultcode>env:Client</faultcode>
            <faultstring>javax.xml.rpc.JAXRPCException:   org.jboss.ws.binding.BindingException: javax.xml.bind.JAXBException: Failed to parse source:Requested element int_1 is not allowed in this position in thes
equence. The next element should be {http://server.reg.src/jaws}int_1</faultstring>
       </env:Fault>
    </env:Body>
</env:Envelope>

[jason_rency]

where can I get jsr 172 source code?(if possible)

[jason_rency]

I mean, sun 's reference implementation

Hi jason_rency,

I am not a WebServices APIs and frameworks specialist but i had problems with .NET > Java integrations i performed before.

At that time i used Axis' wsdl2java tool and compared types with my code.

I also remember of issues with Float and Double types that are not available IN CLDC 1.0 (note that CLDC is the minimum for JSR-172).

However, i am not sure if your case is the same.

At last, note that JSR-172 RI is not publicly available AFAIK:

"The RI and TCK for JSR 172 are available to J2ME licensees through the Java Partner Engineering web site."

hi Jason,

try to test that your .net end point is compatible with wsi basic implementation (used in jsr-179 implementation):
http://www.ws-i.org/Profiles/BasicPr...004-04-16.html
there should be some .net/java bridge tools for such compability tests,
or just write .net<>java bridge and use java implementation,
regards,
Peter

I looked at the jboss web site and it says jboss web serverice conforms to the WS-I basic profile, which eliminates the encoded use.
