entities not detected properly in JUnit Test case (OpenJPA 1.2.2)
Hi,
i am using a pretty straightforward Spring/OpenJPA JUnit Testcase scenario:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "/appContext.xml")
public class DHLLeitcodeCreatorTest {
...
@Test
public void getDHLLeitcode() {
someBean.superDuperAction();
}
}
I am not explicitely declaring my entities in persistence.xml. Its all autodetected via Annotations. (at least during normal runtime).
Inside superDuperAction(), a lot of queries are fired against OpenJPA. It fails on the first Query saying that it cant find Entity DP_PLZ_DA (weird class name, i know).
"Error message: The name "DP_PLZ_DA" is not a recognized entity or ...."
Now when i do this:
@Test
public void getDHLLeitcode() {
DP_PLZ_DA df = new DP_PLZ_DA();
someBean.superDuperAction();
}
It works and it can find the Entity. But why in gods name do i need to instantiate the class by myself in order to get detected? During normal runtime, this is no problem. Kevin Sutter reported something similar here (http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14459507) but i thought i can solve this by upgrading to 1.2.2 but i was mistaken.
So why does OpenJPA fail on registering Entities?

Marc -
I'm willing to bet that your Entities are being loaded before you execute
the query. You could try setting *-verbose:class* on your app server jvm and
add some debug to your app in the first place where you execute the query.
These two pieces of information should help you get a better feeling as to
what is going on.
Now your next question... where is DP_PLZ_DA.class is being loaded? You
could add a static initializer to DP_PLZ_DA.class and dump the stack trace
to figure out who is loading it.
Thanks,
Rick

Hi,
thanks for this pretty straight answer. But one more thing that bothers me. Why is this only an issue while testing? When my app is running, i am pretty sure that i dont use the DP_PLZ_DA class somewhere in the code before the worfklow with the query arrives. So why does it work in normal runtime mode?

>So why does OpenJPA fail on registering Entities?
The problem is that when you don't list your entities, OpenJPA doesn't know
that the alias 'DP_PLZ_DA' is an Entity until the x.y.z.DP_PLZ_DA class is
loaded. If you were to look at an enhanced Entity you would see that OpenJPA
adds a static initializer that will register each Entity with OpenJPA.
An alternative to calling "new DP_PLZ_DA();" would be to add something like
this to each of your testcases.
// List each Entity that this test is going to use.
private Class[] _entities = new
Class[]{x.y.z.DP_PLZ_DA.class,x.y.z.DP_PLZ_DB.class,etc... };
Thanks,
Rick
