Acquiring session not in a tapestry page error
Hi,
Our team started a tapestry / honeycomb / hivemind / hibernate web app
project. A data upload service is needed to load data to the database and
therefore a hivemind eagerload service is written to run this periodical
task. As we want to share the same honeycomb session factory, we inject
hibernate session to the service while the hibernate session is getted from
the honeycomb session factory.
When we tries to save data to the database, the data is still saved to the
database but the following exception occurs:
Property 'webRequest' of <OuterProxy for tapestry.globals.RequestGlobals(
org.apache.tapestry.services.RequestGlobals)> is null.

As the data upload service is a hivemind service but not a tapestry page, I
do not have webRequest object. As Any suggestions?

RE: Acquiring session not in a tapestry page error
Posted by Ma...@bmw.ch.
Oh, sorry,
I think the Audit-Interceptor must be the culprit. I had the same
problem when adding a Message-Driven thingy into one of my projects.
You'll need to define a second instance of the SessionFactory, contrary
to what I told before, like this:
<service-point id="HibernateSessionFactory" parameters-occurs="none"
interface="org.apache.hivemind.ServiceImplementationFactory">
<invoke-factory model="singleton">
<construct autowire-services="false"
class="com.javaforge.honeycomb.hivemind.hibernate.HibernateSessionFactor
y"
initialize-method="init">
<configuration>
honeycomb.hibernate.HibernateSessionFactory
</configuration>
<service>hivemind.ShutdownCoordinator</service>
<service-id/>
<set property="updateSchema"
value="false"/>
<set property="transactionManager"
value="false"/>
</construct>
</invoke-factory>
<interceptor service-id="hivemind.LoggingInterceptor"/>
</service-point>
It's important to turn off autowiring otherwise HiveMind will
auto-inject the wrong AuditInterceptor Service. Of course, if you need
auditing, you can also configure a second instance of the interceptor
and wire it up explicitly.

RE: Acquiring session not in a tapestry page error
Posted by Henry Tong <he...@gmail.com>.
Dear Marcus,
Thank you for your prompt reply. I am using Tapestry 4.0.2 and Honeycomb
0.3.3. For testing purpose, I have changed the configuration file as
follows.
1. Create another Hibernate Eager Load Session
<service-point id='HibernateEagerLoadSession'
interface='org.hibernate.Session'>
<invoke-factory
service-id='honeycomb.hibernate.HibernateSessionFactory' model='threaded'/>
</service-point>
2. Create Dao Service (which extends AbstractPersistenceService) that use
Hibernate EagerLoad Session
<service-point id="GenericDbDao" interface="GenericDbDao">
<invoke-factory>
<construct class="impl.GenericDbDaoImpl">
<service>HibernateEagerLoadSession</service>
</construct>
</invoke-factory>
</service-point>
3. The web project use default honeycomb hibernate session and default
honeycomb hibernate session factory.
The same errors prompt. Any suggestions?
ERROR! [Timer-0]
org.hibernate.impl.SessionImpl.beforeTransactionCompletion(SessionImpl.java:399)
>15> exception in interceptor beforeTransactionCompletion()
java.lang.NullPointerException: Property 'webRequest' of <OuterProxy for
tapestry.globals.RequestGlobals(org.apache.tapestry.services.RequestGlobals)>

You can continue to use the pre-configured Honeycomb-Session for the
Web-Requests.
You should only need to add the EagerLoadSession

Again, you should be fine with the pre-configured session-factory -
unless you want to override something anyway. It seems, you're using
your own implementation of a
session-factory which delegates to the Honeycomb-Session-Factory. There
may be a good reason for that, but I don't think it's necessary for the
problem you described in this thread.

Yes, you can. Just configure a separate instance in HiveMind using your
EagerLoad-HIbernateService.

RE: Acquiring session not in a tapestry page error
Posted by Henry Tong <he...@gmail.com>.
Dear Marcus,
Thanks for your assistance. May I clarify you suggestions?
1. Create two session service
<service-point id='HibernateWebSession'
interface='org.hibernate.Session'>
<invoke-factory service-id='MySessionFactory' model='threaded'/>
</service-point>
<service-point id='HibernateEagerLoadSession'
interface='org.hibernate.Session'>
<invoke-factory service-id='MySessionFactory' model='threaded'/>
</service-point>
2. Create one session factory only (we use
createCoreServiceImplementation(...) to create session)
<service-point id='MySessionFactory' parameters-occurs="none"
interface='org.apache.hivemind.ServiceImplementationFactory'>
<invoke-factory model='singleton'>
<construct class='MySessionFactory'>
<set-service property='hibernateSessionFactory'
service-id='honeycomb.hibernate.HibernateSessionFactory'/>
</construct>
</invoke-factory>
</service-point>
3. The Data Upload Service use the HiberateEagerLoadSession Service.
We are using honeycomb AbstractPersistenceService to update data in the
database in the web app project. Can we use AbstractPersistenceService in
the data upload service?

Sorry, follow-up:
You should get away with just defining a new hibernate session service
with a non-stateful service-model (say threaded), keeping the same
SessionFactory.

RE: Acquiring session not in a tapestry page error
Posted by Ma...@bmw.ch.
Hi Henry,
the Hibernate Session in Honeycomb is per default configure as a
"stateful" service to support session-per-conversation. That means, the
service-model stores the Hibernate-Session into the conversation-context
which is, in a Tapestry context, the Web-Session. A web session is, of
course, not available in your initial load.
I'd suggest that you configure a different Hibernate SessionFactory and
Session service (you can use the same SessionFactory-Config-Point to
minimize redundancy) and use that one with your periodically triggered
