I am really desperate for some experties...not sure if it's inapropriate post it here though. hi all, I deployed the Calculator web service example (EJB3 endpoint jsr181) in the JBOSS4.04GA server and tried to invoke the service from both j2me&j2se client. the j2se client works fine, but when I used the j2me client, the client threw the folling exception: Code: java.rmi.MarshalException: (1)Missing end tag for Body or Envelope by monitoring the network I got the request and response packages: the request: <?xml version="1.0" encoding="utf-8"?>. <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"..xmlns:xs... :soap="http://schemas.xmlsoap.org/soap/envelope/"..xmlns:tns="http://server.reg.src/jaws">. <soap:Body>. <tns:add>. <tns:int_1>4</tns:int_1>. <tns:int_2>6</tns:int_2>. </tns:add>. </soap:Body>. </soap:Envelope>. this is bizzar coz there are extra "." in every line. but it seems the server can un marshal it correctly as the following response was sent back: response: <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-i nstance'> <ns1:result>10</ns1:result> </ns1:addResponse> </env:Body> </env:Envelope> I believe the problem is the client can't unmarshal the response package correctly. don't know why this happened as the response package is well organised soap message. also, I set the client side http version at 1.0 as if I set it to 1.1 the response package would be chunked. (the server side is still 1.1) any one has any idea? big thanks.... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963210#...
