Communication between portlets

[Carlos Torres]

Hi people,

I have 2 portlets in a panel and I need to comunicate, change information, 
between these 2 jsp portlets. How can I make this?

Thank you

I agree with Holger Dewes since all portlets share the same request object, and what 
the portlet will render  depends upon other portlets how to deal with their content.

Actually, I see it the other way around: because (in general) you have
no influence over the rendering order of the portlets, you have to make
sure that order does _not_ matter.

That's why I said, portlet B has to check the request, if portlet B is
the one to display the result of the request. Then it won't matter
whether portlet A has been rendered already. Of course, portlet A could
also be influenced by the request. In that case you either let both
portlets create their result independently or let whoever gets the
result first put it in the request for the others. Anyway, that's how I
do it :-)

RE: communication between portlets

[Holger Dewes]

Hello,

yes, this is possible, since all portlets share the same request object
(runData.getRequest()).
So portlet B has to check the request in its buildNormalContext()
method.

communication between portlets

[sophy]

hi, all
  
 Can I use jetspeed to implement the communication betwee two portlets? For 
example, when I input some text in portlet A and submit it ,then I can see the text in 
Portlet B. 
 
  thanks

  sophy   

YNT: communication between portlets

[Ender Hikmet KILIÇOÐLU]

yes but do not forget that there is an order for portlet process and it
depends on page layout. Maybe you can use global action without giving
js_peid so every portlet get this action. Maybe forward tool used for
internal forwards?

This is no problem. All portlets share the same request/response object, so
you can have a form in one portlet and read the values in another portlet
via
request.getParameter() or runData.getParameters() and then display the
result
in this portlet.

Do you mean closed/minimized etc. ? I'm afraid I don't know this.

communication between portlets

[Tobias Hummrich]

Hi,

I'm trying to create a web application using Jetspeed, but I'm not sure 
if it (or any portal framework, for that matter) offers the 
functionality that I need. More specifically, I'd like to know these two 
things:

1. How can the result of a request sent to one portlet be displayed in a 
different portlet?

2. How can a portlet access the state of another portlet?

Basically, what I'm trying to do is implement a portal that behaves like 
an MDI application. Is that possible, or do I have the wrong idea about 
portals?

Thanks in advance.

Q on communication between Portlets

[Yuji Miyawaki]

Hi,

I am just started to learn JetSpeed and want to implement  portlets
communicating each other.

 Assume a portlet has the function of the tree-view of directory. If a
user
click a directory node in the portlet, then another portlet displays the

listing of the directory node

Please inform me the sample code for implement the function, or the
pointer
to learn the mechanism for it.

Following questions maybe FAQ...
I want to make an application to be a portlet. How can I do it...

The third question is the portlet openes within the portlet.  I read the
mail
archive and found the way to open in another browser page. However, I
cannot
find the way to open within the portlet (not open at the whole browser
window).

Any kind of information, pointers are welcome.

Best regards,

Yuji Miyawaki
