I have the same problem using maven. It uses several classpath. To solve this I
have implemented a custom class embeddableejb3tools.EmbeddableEJB3Container().
Before starting the container I declare at least one session bean class. It
will deploy all the classes deploy in the jar of this classes or in its
directory. Following an example on how to use.
| EJB3Container container = new embeddableejb3tools.EmbeddableEJB3Container();
| container.getAccepted().add(
| container.getArchiveURL(MyService.class));
| container.startup();
| container.scan();
| container.shutdown();
|
The code: 3 classes: an interface for the container, an impl for the EJB3
embeddable and an exception. It can probably be improved. If you do improvement
please keep me inform.
