Struts Plugin with EJB 3.0

[mduffy_lists]

The Struts PlugIn architecture can be used to, "load application-specific data as the web application is starting up." However, when I tried to do this with EJB 3.0 it looks like the plugin is loaded before the session bean DAOs.

Is there any way to configure things so that a Struts plugin can access the features of EJB 3.0? Or is there some feature in JBoss that will accomplish the same thing?

Thx.

You can use a ServicePOJO to accomplish this. Simply place the ServicePOJO in the ejb3 archive, create a dependency on any specific EJBs that you need (or just dependency inject them using the @EJB annotation), then you can use the management lifecycle methods to accomplish what you want.

I'm currently using this method to bootstrap data and other system initialization routines. There are helpful examples in the tutorial.

I'm not familiar with Struts plugins. Is this something you initialize in Servlet initialization?

[mduffy_lists]

Thx.

I see the Service POJOS tutorial; however, when I look in the most recent editions of the EJB 3.0 specs, I do not see a reference for @Service. Can you tell me where the reference is?

It's an extension to the spec. If you are averse to this, you can accomplish the same thing using MBeans, but you'll loose the IoC and simplicity of ServicePOJOs.

Again, so is your problem that Servlet initilalization happens before EJB initialization?

[mduffy_lists]

Yes, it appears the problem is " that Servlet initilalization happens before EJB initialization".

Does anyone have a possible work around for this?

Thx.

I have created a JIRA task for this. We probably won't get to this for a bit as we're working on other bugs/features at the moment. If you find a solution, let me know.

if you want to listen for when it is fixed.
