Please help me if I'm wrong in my understanding and code implementation.

My PM has Start Node, a Script Task and End Node . Script task I had configured the pv's as parameters.

                    processVariables[0] = pvInstance;

                     typedValue = new TypedValue(Long.valueOf(AppianType.STRING), new String("fromAPI"));
                     namedType...

...Value = new NamedTypedValue(typedValue,"wMyOtherText");
                     pvInstance = new ProcessVariableInstance(namedTypeValue);
                     processVariables[1] = pvInstance;


                     typedValue = new TypedValue(Long.valueOf(AppianType.STRING), new String("fromAPI2"));
                     namedTypeValue = new NamedTypedValue(typedValue,"zMyText");
                     pvInstance = new ProcessVariableInstance(namedTypeValue);
                     processVariables[2] = pvInstance;

                    ProcessStartConfig config = new ProcessStartConfig();
                    config.setProcessParameters(processVariables);

                    try {
                              pes.initiateProcess((long)1576, config);
                    } catch (Exception e) {
                              // TODO Auto-generated catch block
                              e.printStackTrace();
                    }

Take a look at the source for Start Process Writer in shared components for ideas and to debug.

(sorry I'm on mobile and couldn't review your code and couldn't copy paste the link to the start process writer record)
