RE: Struts2 Action Class and EJB Injection
ive used OpenEJB with TC then again you could deploy your EAR to a true EJB3 container with a J2EE-AppServer such as GF, WL or AMSServer..even resin would handle EJBs ?

Re: Struts2 Action Class and EJB Injection
Yes, using annotations would be the ideal method.
I think I remember reading that declaring beans as 'remote' when this is
not that case, may cause unnecessary serialization/deserialization as
calls are supposedly being made remotely. Depending on the EJB app
server configuration.
Obviously, this could cause significant overhead when returning large
result sets from a session bean.
I've yet to find where I read that but will update this thread if/when I do.

Hi Wes,
I found a resource on the web that seems to be a simpler solution:

As in the web resource I found, it was necessary to change @Local to @Remote

It worked perfectly using the above.
Here is a link to the resource. What do you think of this solution?

toyed with the notion of creating an ObjectFactory based plugin so
that struts can delegate creation of action classes to the ejb
