Portlet container like pluto or jetspeed on google app engine?
- by Patrick Cornelissen
I am trying to build something "portlet server"-ish on the google app engine.
(as open source)
I'd like to use the JSR168/286 standards, but I think that the restrictions of
the app engine will make it somewhere between tricky and impossible.
Has anyone tried to run jetspeed or an application that uses pluto internally
on the google app engine?
Based on my current knowledge of portlets and the google app engine I'm
anticipating these problems:
A war file with portlets is from the deployment standpoint more or less a
complete webapp (yes, I know that it doesn't really work without a portal
server). The war file may contain it's own web.xml etc.
This makes deployment on the app engine rather difficult, because the apps are
not visible to each other, so all portlet containing archives need to be
included in the war file of the deployed "app engine based portal server".
The "portlets" are (at least in liferay) started as permanent servlet
processes, based on their portlet.xmls and web.xmls which is located in the same spot for
every portlet archive that is loaded. I think this may be problematic in the
app engine, because everything is in one big "web app", so it may be tricky to
access the portlet.xmls from each archive.
This prevents a 100% compatibility in my opinion.
Is here anyone who has any experience with the combination of portlets and the
app engine?
Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run
it on the app engine?
