I am developing a plugin targeting JIRA 4.4.3.
The plugin's execute method does some database operations to invoke an Oracle database. The interaction with the database is handled using Eclipselink. I have the necessary JAR files specified in my project's POM. These get bundled in the plugin JAR. The JPA persistence.xml is in its proper place in the META-INF.
However when the plugin is invoked I get the error
javax.persistence.PersistenceException: No Persistence provider for EntityManager named IpdPU
Any idea what might be causing it? I have heard that you can have problems referencing a JAR that's within a JAR. If that is the case how can I make the Eclipselink & related JARs available to my plugin's logic?
