RE: Acquiring session not in a tapestry page error

[Ovidiu Hurducas]

Hi!
I have a similar problem and I can't find the answer to my problem for
now. I want to update an existing Tapestry/Hivemind/Hibernate application
to use Honeycomb.
In my case the problem appear when I need to access the database service
inside a javax.servlet.Filter.

I get the same error message:

java.lang.NullPointerException: Property 'webRequest' of <OuterProxy for
tapestry.globals.RequestGlobals(org.apache.tapestry.services.RequestGlobals)>
is null.

Any suggestions about this?

You're trying to do something outside the scope of a web request or Tapestry would be setting that up for you.

[Marcus.Schulte]

Honeycomb currently stores conversation state, especially the Hibernate
session, in a Tapestry ASO rather than directly in the session.
Therefore it's inaccessible outside Tapestry.

You have basically two options:
  - replace you Servlet Filter with a custom Tapestry-Service
  - override the ConversationManager, so that it directly relies on the
Http-Session. You'd need some kind of Filter wiring the
ConversationManager to the Session then.
