Recently, a good friend is a heart thought to study EJB, I will follow the footsteps, I have embarked on this EJB.
Why do you say this? In fact, I am a little contradictory, and the EJB3.0 specification is being moved, 2.0 I don't know how long it can
So always wait, but also feel that learning EJB does not necessarily learn its writing code, and better should learn his architecture.
Learn more elegant design patterns by coding, so I still feel that I should go deep into the following.
------------------------------
At the beginning, I first found a HelloEjb, I hope I can experience the outline of EJB from the example.
The example is that the operating environment is under Eclipse, in order to cooperate, the plugin to be under
1, lomboz3.0 corresponds to Eclipse3.0.x, if you use Eclipse3.1.x to find the corresponding Lomboz version
2, EMF (ECLIPSE MODELING FRAMEWORK), this is also necessary
I feel that I feel like the development deployment of EJB, but I have met a very depressed problem.
Unable to use New-Lomboz EJB CREATION WIZARD, other functions are normal, that is, click the EJB wizard to reflect
So uninstalling Eclipse and reloading Lomboz, but each time the effect is the same.
Finally, I found the problem:
- When downloading EMF in Lomboz, the connection to 3.0 is not supported under my Eclipse3.0.1.
- I finally downloaded the EMF provided to 3.1.x and solved the problem after extracting the Eclipse directory.
Then I find that if everything is normal, you should see a such project directory under ResourcePective.

About Lomboz more detailed configuration in Eclipse can refer to Lomboz's official documentation
