Hi all,
I am working on extending smooks functionality on WSO2 ESB Smooks Mediator.
When implementing JPA support with hibernate on smooks mediator, I am
facing an issue of not being able to find the persistence provider. I
placed the persistence.xml file inside a jar which contains the entity
classes (as META-INF/persistence.xml). I added that jar to ESB
repository/components/lib location. Also added all the other required jars
(hibernate-entitymanager, persistence-api, etc) to the same location. But
when executing a sample service I get this error as,
javax.persistence.PersistenceException: No Persistence provider for
EntityManager named db
at
javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:89)
at
javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:60)
It seems that although hibernate-entitymanager jar is added to the
repository/components/lib Smooks can not find the Persistence Provider.
This similar problem had been encountered sometime back and provided with a
solution on a support issue [1]. There an additional script had been added
to wso2server.sh in order to add all the jars inside repository/components/lib
to the classpath. As the client has responded the solution has worked. But
it seems that solution doesn't work in trunk now. We exactly do not know
how that solution worked at that time and why isn't that working now.
So I appreciate any assistance, comments regarding this issue.
Also I came to know that WSO2 BPS has implemented JPA functionality and I
would like to know how you have been supported this ?
