returnMessageContext is getting set to null why?

[Dash Abhisek]

Hi All,

I am using axis2 1.4.1 version in my web service I wanted to know what are the possible reasons for _returnMessageContext to be set to null after the execution of the below code.

org.apache.axis2.context.MessageContext _returnMessageContext = _operationClient.getMessageContext(
                                           org.apache.axis2.wsdl.WSDLConstants.MESSAGE_LABEL_IN_VALUE);

my services.xml is as follows:-

<service name="SecondWebProject" scope="application">
    <description>Mutiply and add Service</description>
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </messageReceivers>
    <parameter name="ServiceClass">com.sub.compul.Maths</parameter>
	<operation name="add" mep="http://www.w3.org/2004/08/wsdl/in-out"/>
	<operation name="multiply" mep="http://www.w3.org/2004/08/wsdl/in-out"/>
</service>

Thanks,
Abhisek
