Problem with multiple datasources and TestNG
Ok, I'm trying to get TestNG to pull data from a secondary database with which it will construct test objects.
I'm running into problems with 2 datasources.
I'm using a project that I generated using the New Seam Project feature of Jboss Tools. So there are 4 projects in my eclipse environment, one of them is called projname-test.
The problem occurs when I add the line
List objectsFound = q.getResultList();
It is in the test class. It is listed below. The error goes away if I comment this one line out.
Now, this is not where the error is actually occuring. The error occurs in my Stateless session bean that tries to use the other datasource. The error only occurs if I perform the query above in my test code prior to the session bean's call to EntityManager's persist.
From MyEntityBean below:
em.persist(myEntity);
It's like it is opening up a transaction in my test code and not closing it, or something, and it screws up the next request to the other datasource.
Note that I'm using a non-jta-datasource... This is because it didn't work to have it be a jta-datsource, because the call is coming from outside the container (or something like that). Since it's not a session bean making the call... that's the conclusion I came to on my own earlier when I was fixing another problem.
The test code uses the projname-test-ds.xml instead of the projname-ds.xml I made them identical... but I'm not sure if the container-managed beans use their own ds.xml file, or if the use the test one.
Any insight would be greatly appreciated.
The full error that I get is this (code is below):
