I have design in which a external application will be called from the portlet and some parameter will be send to the external application. Then external application will do some processing and return some parameter. How external application can return to same page of portlet application with parameter ?.

I'm new to portlet please help me ?. I'm using Spring MVC web flow ?.

Sounds like the job of a web service of some sort to act at the intermediary.

Portlets can access any J2EE resource that is supported by your server - JMS, JDBC, web services, RMI/IIOP. All you need to know is how to code for them.

So, how would you access this external resource in a Servlet? That's probably the same way you'd access it from a Portlet.

Make sense?
