Orchestra does not work within BEA WebLogic JSF portlet - FacesContextFactory
related problem
---------------------------------------------------------------------------------------------
Key: ORCHESTRA-25
URL: https://issues.apache.org/jira/browse/ORCHESTRA-25
Project: MyFaces Orchestra
Issue Type: Bug
Components: FrameworkAdapter
Affects Versions: 1.1
Environment: BEA WebLogic Portal 9.2, BEA WebLogic JSF portlets, Sun
JSF RI 1.1_01, MyFaces Orchestra 1.2 snapshot
Reporter: Gautam Marwaha
I have read about the Orchestra's support for conversation scope and think it
is very promising for an application we're building that needs to support 1)
updates in wizard kind of screens where users submit changes made in multiple
tabs and 2) have this working in scenarios where users do a ctrl+n / open new
browser windows (=> session scope is ruled out)
To get things started I am trying to get an Orchestra example (multiBean)
working on our tech stack - BEA WebLogic Portal 9.2, BEA WebLogic JSF
portlets, Sun JSF RI 1.1_01 and MyFaces Orchestra 1.2 snapshot. We are not
going to have any non-JSF functionality in our application.
So far I have been successful in running the example on BEA WebLogic Portal 9.2
*without* wrapping the JSPs within a JSF portlet. However, as soon as I wrap
the JSP within a JSF portlet, I get the following error on the examples home
page (/start.jsp):
java.lang.ClassCastException: com.sun.faces.context.MyHttpServletRequestWrapper

This issue is showing up because
myfaces-orchestra-core-1.2-SNAPSHOT.jar!faces-config.xml contains Orchestra
related FacesContextFactory classes that are loaded by Faces Servlet upon
startup. Looks like these factories
(org.apache.myfaces.orchestra.lib.jsf.OrchestraFacesContextFactory is one of
them) are not returning valid FacesContext objects (they're returning an object
meant for servlet / non-portlet environments) and cause a ClassCastException in
BEA Portal's classes that appear to be casting the request to FacesRequest,
something like:
(FacesRequest)context.getExternalContext().getRequest();
To fix this problem, I added the BEA Portal specific FacesContextFactory
(present in their faces-adapter.jar!faces-config.xml) into my applications's
faces-config.xml. i.e. the following lines:
<factory>
....
<faces-context-factory>com.bea.portlet.adapter.faces.context.FacesContextFactoryImpl</faces-context-factory>
....
</factory>
This atleast got me to the examples home page (/start.jsp) since the server
appears to have picked up the factory it last loaded. But, there is a side
effect of this change. Now I find that FrameworkAdapter has not been
initialized properly. The error is:
Caused by: java.lang.IllegalStateException: FrameworkAdapter not found

BEA Portal seems to be over-riding the Orchestra FacesContextFactory impl and
not letting it do its per-request operations.
I have looked around for a way of getting the same thing done via Orchestra
filters. The following Orchestra filters are in my web.xml and haven't helped:
-
org.apache.myfaces.orchestra.frameworkAdapter.basic.BasicFrameworkAdapterFilter
-
org.apache.myfaces.orchestra.requestParameterProvider.RequestParameterServletFilter
Even tried adding the
org.apache.myfaces.orchestra.conversation.jsf.filter.OrchestraServletFilter
filter but it did not help.
I am not expecting BEA to fix/change anything on their side. Any chance this
can be fixed in Orchestra?
Thanks,
Gautam
