Input stream is null while reading for incomming message... problem !

[Zakia KAZI AOUL]

Hi,

I just begin developping web services using axis2.

I created my own web service, and the .aar corresponding archive file, and then I deplyed it in the tomcat apache server.

However, After the execution (within the JBuilder environment) of that portion of code:

        Call call = new Call();
            call.setTo(URL_context_ws);
            call.setTransportInfo(Constants.TRANSPORT_HTTP,Constants.TRANSPORT_HTTP,false);
            SOAPFactory fac1 = OMAbstractFactory.getSOAP11Factory();
            SOAPEnvelope envelope = fac1.getDefaultEnvelope();
            OMNamespace namespace = fac1.createOMNamespace("http://example1.org/url_context", "ranglang");
            OMElement rang_lang = fac1.createOMElement((String)"lang", namespace);
            rang_lang.setText("0");
            envelope.getBody().setFirstChild(rang_lang);
            call.invokeBlocking("getLanguage",envelope);

This error code is generated:

org.apache.axis2.AxisFault: Input stream is null while reading for incomming message
        at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:45)
        at org.apache.axis2.clientapi.TwoWayTransportBasedSender.send(TwoWayTransportBasedSender.java:53)
        at org.apache.axis2.clientapi.InOutMEPClient.invokeBlocking(InOutMEPClient.java:177)

        at decision_making_manager.decision_making.<init>(decision_making.java:104)
        at decision_making_manager.decision_main.main(decision_main.java:21)


So is the problem in the trasport , in the web service code or in the web service client ?

Thanks in advance
