Test local interface

[martinganserer]

Hello,

I created a simple entity bean and a session bean that works as a DAO for this entity bean.
I made a small test app in eclipse. When I use the remote interface of my DAO everything works fine. But when I switch to the local interface I get an error like this:

My test app looks like this:

// Get data access object!
CustomerDAO customerDAO = (CustomerDAO) ctx.lookup(CustomerDAO.class.getName());

Can I use the remote interface only when I test my app by this approach?
I don't have to mention that client test app and JBOSS are running on the same machine!

If your client runs in a different vm from the ejb container you need to use Remote interfaces

Hello Kabir,

I checked my project settings. But the vm of jboss and the one of my app are the same!

Do you have any idea what else could be wrong?

[kabirkhan]

I could be wrong, but to me it looks like you are running a standalone client? In which case there will be a separate vm for your client and for jboss whether you run both from whithin Eclipse or not

Hello,

you're right. It is a standalone client. It has a main method. But does that mean that both applications are on the same vm but are remote to each other? What could I do to run my standalone app in the VM of the app server? How else should I test my local interfaces if I don't have any chance with a small test software??

[kabirkhan]

Main client + app running in jboss = 2 vms :-)

One way to test your application would be to deploy an additional bean with a remote interface, calling the local interfaces you want to test. Another to create an MBean that calls the local interfaces. Alternatively you may want to look at using embedded EJB 3 during your testing cycles.

OK,

I think it will use a second entity bean!

But one further question only to be sure about that point:
If I run my application on JBOSS and use Servlets as client, I will be able to use the local interface, won't I?
