Class cast exception in WSO2 custom mediator

Question

I was implementing custom mediator. I need to change payload inside my mediator class. I was using using following code

public boolean mediate(MessageContext context) { 
    

        
        System.out.println("inside the mediate  class pRequest ");
        
        try {
            org.apache.axis2.context.MessageContext axis2MessageContext = 
                      (org.apache.axis2.context.MessageContext) context;
                
            //JsonUtil.newJsonPayload(axis2MessageContext,success, true, true); 
            
        }catch (Exception e) {
            e.printStackTrace();
        }

While executing i get class cast exception as follows,

org.apache.synapse.core.axis2.Axis2MessageContext cannot be cast to org.apache.axis2.context.MessageContext java.lang.ClassCastException: org.apache.synapse.core.axis2.Axis2MessageContext cannot be cast to org.apache.axis2.context.MessageContext Executing custom mediator.....RESTUploadDocument at com.uia.document.RESTUploadDocument.mediate(RESTUploadDocument.java:43) at org.apache.synapse.mediators.ext.ClassMediator.mediate(ClassMediator.java:94) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:109) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.Z93F725A07423FE1C889F448B33D 21F46Z:71) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:158) at org.apache.synapse.rest.Resource.process(Resource.java:331) at org.apache.synapse.rest.API.process(API.java:440) at org.apache.synapse.rest.RESTRequestHandler.apiProcess(RESTRequestHandler.java:135) at org.apache.synapse.rest.RESTRequestHandler.dispatchToAPI(RESTRequestHandler.java:113) at org.apache.synapse.rest.RESTRequestHandler.process(RESTRequestHandler.java:71 ) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.injectMessage(Axis2SynapseEnvironment.java:325) at org.apache.synapse.core.axis2.SynapseMessageReceiver.receive(SynapseMessageReceiver.java:98) at org.apache.axis2.engine.AxisEngine.r Is there anything wrong in the code, what would be the right way to change payload inside the custom mediator

Answer 1

org.apache.axis2.context.MessageContext axis2MC 
          = ((Axis2MessageContext) context).getAxis2MessageContext();
