BPM process interactive activity(JSP) - external webservice method interac

Question

I am using Oracle BPM studio 10.3.1.0.
I have one external web service published on glassfish application server, I have introspected it in my BPM process using its WSDL.
Now one of my BPM process interactive activity is there, which is represented by one JSP, I am giving some input to my JSP.
I want this input to be passed to the web service method as a parameter, and it should fetch the output, so basically I want to invoke the web service method, could you please guide me how to do it?
Thanks & Regards

I dont know if this is best way to do that, but I have a similar situation here, and I'm using AJAX do call the webservice method by BPM and retrieve data.
Something like this:
1 - Create the XMLHttpRequest() object in your jsp (if you need I have the entire code)
2 - Create the a JavaScript method for to call the OBPM method in your component
function mymethod(arg1, arg2, arg3)
xmlhttp.onreadystatechange=function()
                                                  if( xmlhttp.readyState==4 )
                                                       document.getElementById("AnyDIV").innerHTML = xmlhttp.responseText;
     var resp = "<f:invokeUrl var='YourComponenteName' methodName='YourMethodName'/>";
//Incude how many args your need here
     resp+="&arg1=" + arg1;
     resp+="&arg2=" + arg2;
     resp+="&arg3=" + arg3;
     xmlhttp.open("POST",resp,true);
     xmlhttp.send(null);
3 - You'll need a div html tag called "AnyDIV" to receive the BPM answer
4 - On you BPM component, in YourMethodName method (needs to be ServerSide = no), create two args, the first is httpRequest type (name request), and the second is httpResponse type (name response) (fuego lib)
5 - Type the code below in your BPM method to send info back to the JSP
//getting the args
String arg1 = request.getParameter(string : "arg1");
String arg2 = request.getParameter(string : "arg2");
String arg3     = request.getParameter(string : "arg3");
//Do the webservice call here, prepare the html answer and put it into an string variable
strReturn = "bla bla bla";
//Send the anwser back to the jsp
response.bodyTextContent(arg1 : strReturn);
Or you can do this using xml answer and deal with the tags with javascript
that's it
