4. Portel to portel communication    coderanch.com

Originally posted by Jessica Sant: Inter Portlet Communication is not covered by the JSR-168 spec, Actually, it is, although it is not done so explicitly. It can be done by setting session variables with the APPLICATION_SCOPE flag, which makes data available to other portlets in the same portal. By default, all session variables are set with a PORTLET_SCOPE flag, so by ...

5. Portlet Communication: What is application scope, anyway?    coderanch.com

Hi all, There is a way to get JSR 168 portlets in the same portlet application to communicate with each other. As others have said (see http://www.jroller.com/page/RickHigh?entry=jsr_168_inter_portlet_communication especially for details), if one portlet puts an object in the portlet session at "application scope," then another portlet in the same portlet application can access that variable. For example, here's some code from ...

6. portlet communication - sending object not string...    coderanch.com

Hi, you can pass the string message to the portlets in any of the portlet application. You can use DefaultPortletMessage interface for this. But messages other than string can be passed to the same portlet application only. you can make use of PortletMessage interface for this. I have done this in IBM Portlet API.

Suppose you have two pageflow portlets... 1. EventGenerator.portlet 2. Listener.portlet If you want to do the communication between the two, set the Listen To attribute of Listener portlet as ...

9. Inter-portlet communication    coderanch.com

I'm analyzing the approach to developing a portal in websphere 6. The implementation is going to require that communication take place between portlets that exist on separate pages. Documentation I'm coming across seems to explicitly note that it's inter-portlet communication for the same page. Is the portlet communication going to be different when they're on a separate page? Won't that still ...





10. Inter portlet application communication    coderanch.com

What type of credentials are you trying to share? Portlets can't really communicate like this. Portlets are separate war files, and as such, are really separate applications with separate classloaders. You can almost think of them as separate Servlet/JSP applications. Communication between them isn't all that easy. Now, the portal itself manages user rights, and usually, a portal server provides a ...

13. Inter-portlet communication    coderanch.com

The AJAX way is very interesting. I'd never thought of that, and I haven't seen that even suggested in this portal forum. Very kewl indeed! Knowing the DIV tag name in one portlet of another portlet seems like some pretty tight coupling, but probably not that bad if the portlets are packaged in the same war file. The other concern is ...

15. Inter Portlet communication    coderanch.com

Well, with JSR168, we don't really have inter-portlet communication. If portlets are in a common war file, you can share information through the application scope of the PortletSession, but that's about it. Remember, portlets are intended to be isolated little content spots. They're not really supposed to depend upon each other for communication. For what you're doing, you might just want ...
