The ServiceClass object does not implement the required method in the following form: OMElement add(OMElement e)

I am unable to figure out where the error is occurring. I checked my Axis2.xml and I have installed the latest Axis2 API. I am currently using Apache Tomcat 8 and JDK 1.8 for development.

Exception in thread "main" org.apache.axis2.AxisFault: The ServiceClass object does not implement the required method in the following form: OMElement add(OMElement e)

Solution

Yeah I did. I finally figured out that in Axis2.xml we need to add

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" /> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

This snippet to make it work. I am not sure why this is important instead of default

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver"/> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>.

Thanks everyone for your prompt replies. Really helped me a lot to figure out what had to be done.
