Papi-ws BPM+ESB Integrat

Question

Below is my code snippet. I'm trying to create a new instance of the process and I'm trying to pass in an argument and for the life of me I can't figure this out.
The over arching thing I'm trying to do is to setup the BPM to work well with the ESB so a proxy can be called on the ESB from a web service the then ESB will call the BPM and the BPM will do it's thing and return a value to the ESB.
I'm having a horrible time with this integration if anyone has any ideas it would be much appreciated.
Thank you

KeyValuePair[] keyValues = new KeyValuePair[4];
               keyValues[0] = new KeyValuePair();
               keyValues[0].setKey("ssn_arg");
               keyValues[0].setValue("value");
               //argument set name. Unless you have created another argument set, the default name is "BeginIn"
               String argumentSetName = "BeginIn";                
Holder<InstanceInfoBean> arg2 = new Holder<InstanceInfoBean>();
                    Holder<ArgumentsBean> arg1 = new Holder<ArgumentsBean>();
                    ArgumentsBean argBean;
                    //argBean.getArguments();
                    Arguments arg = new Arguments();
papiWebServicePort.processCreateInstance(processId,argumentSetName,arg1, "WHAT GOES HERE");

Hi,
You can use both interfaces but keep in mind that when exposing a process as a webservice the two activities that you can invoke are the Begin and the Notification Wait.
