Re: Inject EJB 3 into Tapestry 4 page
Hi
Sorry for Off topic, but that's amazing how simple the solution is, I
can't stop wondering how a small group of people (read Hivemind and
Tapestry developers) and especially Howard were so smart to create
such a beautiful, simple and flexible solution, where such problems
like integration with EJB3 can be solved so simple and concise.
BTW thank you Denis for the solution, I'll use it in my code as well.

All you have to do is create a hivemind object provider that will supply you
with the information you want. Something like this:
public class EJBObjectProvider implements ObjectProvider {
public Object provideObject(Module module, Class propertyType, String
locator, Location location) {
return jndiLookup(locator);
}
}
This is a bit simplified. In my case I use a caching mechanism to save on
jndi lookups.
Then you have to tell hivemind about your new object provider by adding to
you hivemodule.xml:
I'm also injecting an application state manager for my own logic, but you
can use anything here. Also add the following:
That's it. Now you can inject any EJBs by simply adding something like this
in your page or component:
@InjectObject("ejb:myBeanJndiName")
public abstract MyBean getMyBean();
I hope it was helpful. I really don't know that much about hivemind use so
it took me some tapestry source code exploring to figure this one out. I
welcome any suggestions on how to improve this.
Cheers,
Denis

RE: Inject EJB 3 into Tapestry 4 page
No, nothing. I didn't look very far since it's not critical for me. I'm thinking that I could eventually write a hivemind service that wraps any EJB I need. It wouldn't be as clean, but it would be enough, at least in my case.

RE: Inject EJB 3 into Tapestry 4 page
That's just about what I need, but for EJB 3. This service seems to assume EJB 2.x since it requires a home interface.
