---------------------------------------------

I am able to retrive inputs and outputs.. here is some sample code. 

                WorkflowInstanceNodeData nodeData = 
workflowInstanceData.getNodeData(nodeId);
                List<WorkflowInstanceNodePortData> inputData = 
nodeData.getInputData();
                List<WorkflowInstanceNodePortData> outputData = 
nodeData.getOutputData();


                for (WorkflowInstanceNodePortData workflowInstanceNodePortData 
: inputData) {
                    List<NameValue> ioParameterData = null;
                    try {
                        ioParameterData = 
XBayaUtil.getIOParameterData(workflowInstanceNodePortData.getValue());
                    }  catch (Exception e) {
                        e.printStackTrace();
                    }
                    for (NameValue next : ioParameterData) {
                   // next.getName() and next.getValue()
                    }
                   
                }
                for (WorkflowInstanceNodePortData workflowInstanceNodePortData 
: outputData) {
                    List<NameValue> ioParameterData = null;
                    try {
                        ioParameterData = 
XBayaUtil.getIOParameterData(workflowInstanceNodePortData.getValue());
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    for (NameValue next : ioParameterData) {
                 // next.getName() and next.getValue()
                          
                    }
                    }
                }
