I sent an e-mail a few weeks ago asking about injecting EJBs in tapestry
pages. I found a way to do it, so I'm sharing it with the list since there
were other people interested. It's really very easy.
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:
<service-point id="EJBObjectProvider"
interface="org.apache.hivemind.service.ObjectProvider">
<invoke-factory>
<construct class="EJBObjectProvider">
<set-object property="applicationStateManager"
value="infrastructure:applicationStateManager"/>
</construct>
</invoke-factory>
</service-point>
I'm also injecting an application state manager for my own logic, but you
can use anything here. Also add the following:
<contribution configuration-id="hivemind.ObjectProviders">
<provider prefix="ejb" service-id="EJBObjectProvider"/>
</contribution>
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
