Resolution: Fixed
Fix Version/s: (was: 2.0-M2)
2.0-M4
1.2
Assignee: David Jencks (was: Jeff Genender)
Peter Petersson has succeeded in running Roller on geronimo 1.2(-SNAPSHOT) so I
think we can conclude we have fixed this. c.f. GERONIMO-2994.
> Hibernate passes connections between servlets which we don't support

> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: connector
> Affects Versions: 1.1.1, 1.2
> Reporter: David Jencks
> Assigned To: David Jencks
> Fix For: 1.2, 2.0-M4

>
> This is based on examination of roller running in geronimo-tomcat and is
> partly speculation. There's certainly a problem.
> 1. request sets InstanceContext 1 in ConnectionTrackingCoordinator.
> 2. roller starts a persistence context (in hibernate jargon a session) in a
> servlet filter. No connection is opened yet
> 3. tiles dispatches to a jsp
> 4. dispatch sets InstanceContext 2 in CTC
> 5. jsp does something persistent causing hibernate to open a db connection.
> This is registered with IC 2.
> 6. jsp dispatch returns, so IC 1 is set in CTC
> 7. roller commits the persistence context in the servlet filter, which closes
> the connection. Closing the connection attempts to unregister from the
> current IC. IC 1 doesn't know anything about this connection..... we get an
> NPE.
> The solution isn't clear to me at the moment.
