Confirmation about portlet application and portlet

[Masumi Ito <ma...@mb.infosnow.ne.jp>]

Hi, All.
There are several points I want to confirm about portlet 
application and portlet. 


1. Can we include a number of portlets in one portlet 
application?
If possible, these portlets can share same session with cookie 
initialized per group(portlet application). And then it 
seems that deployment working of portlet is carried out not per 
portlet but per portlet application, so by just once installing 
a portlet application in Tomcat, WSRP Producer can
expose multi-portlets included in it as WSRP portlets.
(In this case, these can be different kinds of portlets.)


2. If 1. is possible, all of these portlets' meta infomation 
need to be written anywhere.  Portlet.xml corresponds to this 
in JSR168 Spec. 
Well, should we prepare portlet.xml files as many as the 
number of portlets included in the portlet application? 
Or prepare a portlet.xml file and write many meta-info about 
them in it?


3. If both 1. and 2. are OK, can a portlet call for other 
portlets included in the same portlet application with same 
session shared?
If so, we can make portlet application utilizing coordination 
between portlets.

Thanks.

yes you can, this is the way jsr168 describes it.
A portlet application can consist of multiple portlets.

Same as the jsr168 spec & pluto implementation (since we are using their 
container),
One portlet.xml containing info about all portlets.

no, there is no portlet forwarding/including in jsr168.

Coordination of portlets is not specified yet neither in the portlet 
spec nor in wsrp.
However both committees will be/are working on coordination and will be 
specified in the next spec versions.
