Re: T5: tapestry-hibernate failing in today's 5.0.6 snapshot and eclipse + jetty launcher

Tue, 16 Oct 2007 23:12:19 -0700

For what its worth I'm not doing any tinkering/contributing in my app module. I had simply added tapestry-hibernate to my project and was @Injecting the Session as needed. What is really odd is that it works with the mvn jetty plugin but not through eclipse...

I haven't spent any more time with it since last night. I'm using Tomcat,
and tried both through intellij and through mvn tomcat:deploy both get the
same error. I'll be spending more time with it tonight, if I figure out the
exact problem I'll let you know.

It's possible that I'm doing something in my AppModule that is incompatible
with the new changes. I've implemented my own HibernateSessionManager... I
don't have access to the full stack trace right now but it fails when
injecting the HibernateSessionSource complaining that there is no
implementation of org.apache.tapestry.ioc.Configuration.

   /**
     * The hibernate session manager doesn't handle errors well, replace it
with
     * a copy that does a rollback after an error.
     */
    @Scope(IOCConstants.PERTHREAD_SCOPE)
    public static HibernateSessionManager buildPatch(
            HibernateSessionSource sessionSource,
            ThreadCleanupHub threadCleanupHub) {
        HibernateSessionManagerImpl service = new
HibernateSessionManagerImpl(sessionSource);
        threadCleanupHub.addThreadCleanupListener(service);
        return service;
    }

    public static void contributeAlias(
            @InjectService("Patch")
            HibernateSessionManager sessionMgr,
            Configuration<AliasContribution> configuration) {
        configuration.add(AliasContribution.create(
HibernateSessionManager.class, sessionMgr));
    }

Are you guys still getting errors with this?

I grabbed the nightly build and also ran into problems with my hibernate
module. I was getting an error that
org.apache.tapestry.ioc.Configurationhad no implementation.

The hibernate configuration was changed recently for this defect:
https://issues.apache.org/jira/browse/TAPESTRY-1372 it could be related

( I

have done only cursory investigation)

I updated and built 5.0.6-SNAPSHOT today, and now I get a goofy error
when running my app through the eclipse jetty launcher (which has

worked

fine). Firstly let me say that I've been building 5.0.6 daily for a

week

or 2 now, and I've not run into this before now.

If I try to access a page that @Injects a hibernate Session, I get the
following exception:

org.apache.tapestry.internal.services.TransformationException: Error
obtaining injected value for field
com.propertypix.www.pages.Start.session: No service implements the
interface org.hibernate.Session.

If I launch using mvn jetty:run, all works as usual. I don't know if

app

versions are to blame, but eclipse launches jetty-5.1.12, while the
maven one uses whatever the plugin calls for. That is, I'm not sure

what

that one uses, but I've not changed the config - the maven version is
2.0.7.

If anyone knows why this happens and how to fix it, I'd be grateful.
Following is that lovely stack trace I mentioned:

[ERROR] RequestExceptionHandler Processing of request failed with
