Re: Shale Blank Portlet

I am attempting to get the Shale Blank starter app implemented as a
portlet
running in the Pluto 1.1 portlet container using the Apache Portals JSF
Bridge and have not had much luck in getting it working. I am just
starting
to dive into Shale and JSF so I thought I'd ask if anyone has tried this
and
might provide me with some insights into what could be going wrong.

The first problem I encountered with converting the Blank war is that
using
the jsp:forward to "/welcome.faces" within index.jsp results in "
javax.faces.FacesException: Unsupported context type
org.apache.catalina.core.ApplicationContextFacade" when the JSF bridge
tries
to obtain the faces context. I tried replacing the jsp:forward with a
jsp:include, which is what pluto commonly prefers, but the result was the
same.

With Pluto, the index.jsp reference is made in the portlet-app descriptor
instead of in the welcome-file element of the web-app descriptor. When I
tried replacing the "/index.jsp" declaration in the portlet-app descriptor
with "/welcome.faces" I don't get an exception but it appears that a lot
of
the LifecycleListener behavior gets skipped and while the WelcomeBean gets
constructed and accessed, the bean's prerender method never gets called so
the date does not get initialized or get displayed next to the " The
current
date and time is:" label. I've included debug log entries for both the web
app and portlet implementations of Shale Blank at the end of this message.

My current thinking is to try to convert the JSF Portlet Demo from the
Portals Bridges project to the Shale framework. I have gotten the JSF
Portlet Demo working for the most part but I have a sneaking suspicion
that
I will eventually run into the same issue(s) that I am currently facing
with
converting Shale Blank into a portlet.

It is pretty likely that there are problems with running Shale in portlets.
For example, any functionality that relies on a Servlet Filter (or other
aspects of the Servlet API directly) is going to fail.  Therefore, I've
filed a bug report[1] in the issue tracking system to monitor this issue.
Feel free to add comments about your own experiences to this report.

I have tentatively tagged this as targeted fo 1.0.4 (i.e. the next release),
even though we are trying to keep the scope of this very small in order to
get it out quickly (ideally in time for ApacheCon US next month).  But this
is a really important issue, so I'll try to persuade the other developers
that we need to deal with it in this time frame.
