Hello,

I am having an issue with JpaRestaurantDaoTests.

protected void onSetUpInTransaction() runs before every test.
So the 2nd test fails because of a duplicate primary key.
Also I notice the data isn't being rolled back after all the tests are done.
Do I need to have a onTearDownAfterTransaction() method [that was omitted from the blog code]as well or am I missing a setting?

[...] The motivation behind this blog entry is to provide a simple step-by-step guide for getting started with JPA in a standalone environment with the Spring Framework. While the JPA specification originated as the persistence mechanism for EJB 3.0, it was fortunately recognized that any such mechanism should in fact be able to persist simple POJOs. Therefore, with a handful of JARs in your classpath and a few Spring-configured beans, you can begin experimenting with JPA code within your favorite IDE. I will be using Glassfish JPA – which is the reference implementation and is based upon Oracle’s TopLink ORM framework. [Read More] [...]

Update: Using loadtime weaving like this: solves the problem. However, this cannot be used in production, as GWT (Jetty) does not seem to pick the -javaagent VM option.

I've got it all working nicely (JPA Spring MySQL JDBC driver etc.) but I have run into this weird problem and I'm just wondering whether anyone has seen this anywhere else: essentially, the VERY FIRST Junit test that I run, fails with the trace below; then, all the others work fine and pass without a problem.

It looks as if the very first time the JDBC driver from the mysql jar is not loaded, but I can't quite understand why (note, it does not matter which test runs first, or from which class/package, regardless, the first one will always fail).

Trace is here:

The actual test is trivial:

/*
* For some mysterious reason, the very first test, when using JPA, fails because it
* cannot find the MySQL driver. All the others then pass.
*
* TODO (marco) find the root cause of this weird behaviour and fix it
*/
public void testDummy() {
assertTrue(true);
}

Any ideas?
