Parameter Passing using RaiseEvent

Question

Pardon me if this is a stupid question,I've just finished reading chapter 10 of the web dev guide. Anyway, here it goes:
Using RaiseEvent I can pass parameter that can be used by RegisterForEvent and this parameter can be used by the function that is registered for that action.
sample:
document.PCC.RaiseEvent("urn:schemas.acme.com:email","MailArrived",var)
document.PCC.RegisterForEvent("urn:schemas.acme.com:email","MailArrived",AcmeGotMail)
function AcmeGotMail(){
alert("this is the parameter: " + var )
Question is I would like to pass that var to a jsp page,how can I do that?

Answer 1

The only way I could think this would work would be to jump to that other JSP page when the event occurred. You could add control args (key=value pairs) for any number of arguments you wanted to read in the JSP page, and simpy make sure that JSP page is within the gateway space of the portlet web service.
function AcmeGotMail(){
window.location="nameofjsppagehere.jsp?arg1=val1&arg2=val2"
Then in your "landing" page (nameofjsppagehere.jsp) you would parse the arguments using standard JSP parameter parsing methods.
Classic portlet programming would have you set portlet preferences using the EDK on one page and pick them up on a second page you jump to. Try downloading the EDK sample "Quick Start - Java" from the Portlet samples area of the Developer tab under the Support Center. You might look at setprefs2.jsp and getprefs.jsp.
