Communication between the portlets can be done by Presentation Context.

Secondly you can aso do the samething by providing the listeningTo

attribute of one portlet as the portlet id of second one.

Sai,
If the two portlets are in the same Application you can do this.
Get the text box entries from the jsp. Store the values in the PortletSession in your Portlet class. Use Application scope for the session.
Get the attributes from the PortletSession in the second portlet.

Thanks.

With two text fields username and password, jpf portlet is better. Why you are creating jsp portlet for that.

Create a jpf portlet. After the rendering of the portlet, From its begin action, forward to login.jsp. There you will allow user to enter username and password details. On submission, call say process action of same jpf. In process action, you need to retrieve the request parameters using getRequest() method.

Then set login details in outer request so that other non-page flow portlet like a jsp portlet which are not the part of page flow can get it from request.

with request scope, only jsp and actions which are part of page flow can retrive it from request scope. However, if you want to get it in a different portlet which is definitely not a part of this page flow, then you require outer request.

How will you create an instance of outerRequest here is the code....

HttpServletRequest outerRequest=ScopedServletUtils.getOuterRequest(getRequest());
outerRequest.setAttribute("key", "value");

Hope this will help

There is no book in India or any url you an find what I told you. bea online help is the ony resource which you have already posted. I purchased one book from US and that was on Weblogic workshop. That book covers to some extent weblogic portal things.

"jpf portlet" Yes, but jpf is proprietary of BEA, so if you use it you are now vendor locked. jpf is not defined in the Portlet Spec.

If you put the attribute into the Application scope from one portlet, you must remember that it will only be there for the other portlet if the processAction of the first portlet is called, if a different Portlet on the page has their processAction called, then the attribute will not be there for the other Portlet.

Sai,
You can refer this example.
consider CityPortlet and WeatherPortlet, two portlets in the same application.

In processAction() of CityPortlet:
portletSession.setAttribute("cityName", newCityName, PortletSession.APPLICATION_SCOPE);
In the WeatherPortlet, you can retrieve the changed city name by getting it from the PortletSession:

In doView() of WeatherPortlet:
currentCityName=(String)portletSession.getAttribute("cityName",PortletSession.APPLICATION_SCOPE);

Remember the following from Mark's reply
If you put the attribute into the Application scope from one portlet, you must remember that it will only be there for the other portlet if the processAction of the first portlet is called, if a different Portlet on the page has their processAction called, then the attribute will not be there for the other Portlet.

Thanks.
