Built-in GlassFish ignores Maven test resources

Question

I have several beans sessions for which I wrote unit tests. I installed Maven to include persistence.xml in the src / main / resources / META-INF directory, which references the local MySQL database for development purposes. I have another persistence.xml file in the src / test / resources / META-INF directory that references the Derby __default built-in database. Tests are deployed to the GlassFish 3.1 integrated container.

When I run the tests, I get the following error:

java.lang.RuntimeException: javax.naming.NamingException: Lookup failed for 'jdbc/mylog' 

jdbc / mylog is the MySQL database referenced by the persistence unit in the main directory. Obviously, it ignores the persistence block in the test directory, but I don't know why.

Maven sets the class path correctly, as far as I can tell, with the test classes in front of the classes and a look in the actual target / test-classes / META-INF directory shows that it copied the correct Derby built-in block, persistence.

[DEBUG] Test Classpath :
[DEBUG]   C:\Users\Laurens\Documents\Projects\Mylog\target\test-classes

Any hint of how GlassFish uses the right persistence system is greatly appreciated! Thank!

Answer 3

This answer may seem silly, but I was looking for a way to run those tests from eclipse to Run As→ JUnit Test. Here is how I did it:

@BeforeClass
public static void setUp() throws IOException {
    Files.copy(new File("target/test-classes/META-INF/persistence.xml"), new File("target/classes/META-INF/persistence.xml"));
    // ...
}

I just copy test / persistence.xml to classes / persistence.xml. It works.
