Subject [jira] Commented: (PORTLETBRIDGE-48) IllegalStateException in Websphere Portal.
Date Thu, 25 Sep 2008 22:47:44 GMT


Michael Freedman commented on PORTLETBRIDGE-48:

Felix.  Can you confirm that its the Faces implementation (or an extension you are running
with it) and not the bridge itself that makes the ExternalContext.setRequestCharacterEncoding
call?  I can't find any code references in the bridge itself that makes this call.

That being -- I see your point concerning the JSR-168 spec.  Looks like WebSphere is the first
truly strict portlet container we have run on.  I.e. Though the spec clearly states that getPortletInputStream
and getReader throw an IllegalStateException if url encoded data -- it only implies the setCharacterEncoding
will also do so.  I.e. the conformance test is just on these first two calls.  setCharacterEncoding
throws an exception only if an inputstream or reader have already been gotten.  In the websphere
case they seem to process the parameters before calling the portlet and hence setCharacterEncoding
throws the exception.  In the other container my guess is that that don't process the parameters
until first access and hence setCharacterEncoding doesn't thrown the exception even though
calling either of the two other calls should (to pass the conformance test).  Kind of weird

I will talk the ExpertGroup about how we should deal with this.  I.e. include something like
your patch (and spell it out in the spec) or do something broader like try/catch the exception
-- or ignore completely and push the problem back to Faces which should catch/handle the error
as it can happen in the servlet environment.  I think the lastis unlikely particularly if
you tell us that the problem is in the Faces impl itself (i.e. it call the setCharacterEncoding
call).  Please let me know.

> The bridge tries to set the character encoding in the action phase. In Websphere Portal
this results in an IllegalStateException as the HTTP body seems to be accessed already by
the portal server.
