The built-in container openejb cannot find persistence.xml

I use openEjb in native mode to test a session without a bean that has an EntityManager introduced. However, when I run the test, it fails because it cannot initialize the application. When I see the console, I also see an error related to the inability to find persistence.xml

Note. I tried putting WebContent as well as META-INF in the classpath, but that does not help either.

Update:

Something very strange in finding resources when using openb + eclipse.

  • I added WebContent to the source folders. I stopped getting persistence.xml error, but now I get an error message that says that openbc could not find the managed resource
  • I added WebContent to the source folders, but with a different output folder (using allowed output folders for the source folders), and the persistence.xml error starts again.
  • I copied META-INF to 'test', which is the source folder for all tests, and everything works fine
  • As for points 1 and 2, the problem is that WEB-INF is also part of WebContent. If I exclude WEB-INF, then again openejb can find persistence.xml in the test, and the test passes fine

I honestly don't know what is going on.

I insert all the relevant errors and code below.

Stack of error due to JUnit error in Eclipse

I got the same exception, and the problem was that two persistence.xml were in the way of the OpenEJB classes.

When I deleted one of them, the problem was resolved.

The exception message is not useful here for the OpenEJB part, but if you are debugging the org.apache.openejb.config.Appmodule hasFailures() or hasErrors() method, you can see more useful information in EjbModule.getValidation() calls! (Version 4.0.0).

Maven creates a directory structure for web projects, as shown below:

 src->main-+->java +->resources->META-INF +->webapp->WEB-INF

To solve the problem, you must create the [META-INF] directory in the [resources] directory and place the persistence.xml file there.

The main problem is that when you run junit, JUnit begins to think that the WAR file as a JAR file tries to find the persistance.xml file in META-INF as root, while in the WAR file META-INF it is created inside the WebContent folder. I just created a symbolic link in the src folder pointing to the original META-INF. And voilla ............... it worked. :)
