Hi guys, I'm new to EJB3 so maybe it's a real dumb question but I'm sitting 3
days with this error right now and slowly becoming crazy.
The problem is, JBoss 4.2 can't find my entity classes. As it starts the persistence I
get an error (see bellow).
Here is my persistence.xml:
<persistence-unit name="database"
transaction-type="RESOURCE_LOCAL">
<jta-data-source>java:/MySqlDS</jta-data-source>
</persistence-unit>
mysql-ds.xml is OK and JBoss reads it. It's called MySqlDS in JNDI.
So the problem is, when I do:
entityManagerFactory = Persistence.createEntityManagerFactory("database", new
HashMap());
I get this error:
