how to use ejb 3.1/3.2 in struts2?
Hello, everyone.
I suppose this is very old question to struts user list.
how to use EJB 3.1/3.2 in struts2?
I did some research on google. but I totally no idea what’s the exactly solution for this.
some one said use cdi plugin. but if I use cdi plugin, I guess it can be @inject a ebb into action class. but if I want to inject a remote EJB interface, I think it is not work.
also, some one said use JNDI lookup , I suppose it can get it done. but I think it is very ugly way for it.
is there any better solution for this?
any comments?
Many many thanks
Mike

after testing.
that CDI plugin can work on Glassfish4.1.1 and wildly 10
so, I think it will be better to it
thanks everyone

Hi, Martin.
thanks for your example.
I guess it is not code in struts? is it spring code?
anyway, I check the original code. but I feel I don’t have much knowledge for spring. so, I have to take much time learn the more code for this. but finally, I gave up that part, but I think it is a way. through I didn’t do test for it.
and I found another interesting thing is:
I used java EE (GlashFish4.1.1), I guess it support Java EE version is 7.
so, I write a example for struts + struts-cdi-plugin.
I found I can use @EJB in action directly.
also, both @Inject and @EJB work well for this.
really thanks Martin and Paul.

Are you using an EE 7 server? I believe 7 integrates CDI and EJB so you can
@Inject your remote bean interfaces. This may also be available in 6, but
you'd have to research that.
PS: @EJB is a specialized injection annotation that only deals with EJB.
Obviously, but just wanted to point that out.
Cheers,
Paul
