EJB3 tutorial, part 04: Introducing JPA

mati — Mon, 15 Feb 2010 21:07:51 +0000

In the last post about EJB3 (phew, three months ego ...) we discussed the session beans' lifecycle callbacks. So far we know how to create a stateless (or stateful) session bean and call it from a standalone client. We used JBoss Tools for development. In this post I would like to switch to Netbeans 6.8 and [...]

mati — Mon, 16 Nov 2009 23:42:25 +0000

In previous posts we've learned how to create Session Beans (both Statless and Stateful). In this post I would like to show how to use lifecycle callbacks. What are lifecycle callbacks?

Mocking static methods with PowerMock

mati — Mon, 16 Nov 2009 20:53:25 +0000

Unit testing is great. As we learn it it's excellent. As we work on greenfield projects it's beautiful and sweet. The real problems start on the real projects. Sometimes you must test classes that depend on other classes. A common solution is mocking. If you own all the implementation it is easy, as you can create [...]
