Hi Jason,

I do the same thing.  I have portlet that allows me to generate other portlets.  I'm 
sure, at least from a Jetspeed stand point, we will retain this functionality. 

Through jetspeed, you will still have access to the registry info, either directly 
through the registry service or through JMX MBeans.

Subject: JSR 168 and Jetspeed Registry APIs

Upon review of JSR 168, it is clear that the spec requires the use of a deployment 
descriptor (portlet.xml) to formally define all known portlets in a portlet 
application.� On my project we have exposed the Jetspeed Registry APIs via a Servlet 
to dynamically define new portlets.� For example, we can provide a couple of 
parameters to our custom servlet which in turn translates the query args into registry 
API calls, and <poof> we have a new Portlet defined that shows up in the pick list,� 
<poof> we can delete an existing portlet, etc.� In many ways, its a non-visual 
interface into the admin pages of Jetspeed.
�
With JSR 168 moving to a deployment descriptor metaphor, will this capability of 
dynamically adding portlets to an existing application be lost?� 
�
There is no API in J2EE that formally modifies existing deployment descriptors.� For 
example, if I dynamically add a new portlet, there is no formal API for updating the 
portlet.xml to reflect the addition of that new portlet.� Bear in mind I'm talking 
about referencing existing portlet classes, e.g. IFramePortlet, where today I can 
declare new portlets dynamically via the Jetspeed Registry APIs and simply pass in my 
parameters like source, height, etc.� There are no requirements to deploy a new Java 
class that represents that portlet.� In Jetspeet .xreg terms, the net-net is that the 
Registry API's set their attributes to something like
�
<portlet-entry name="My Dynamic Portlet" type="ref" parent="IFramePortlet">
...
</portlet-entry>
�
and a new entry is created and shows up in the appropriate .xreg file.� While this 
continue to be the case even after JSR 168 is incorporated?� I'm just confused about 
where the portlet.xml file will fit into the process.� 
�
It would be a travesty to lose dynamic portlet creation in the name of a deployment 
descriptor architecture!!
