Disabling Seam Transaction Managment and Acquiring Entity Ma

[fady.matar]

I'm adding new features to an application and those features are implemented in JBoss Seam. The existing application uses Hibernate / JSF and has its own way of handling its persistence.

The additional seam features require a managed persistence context defined in components.xml

Whenever I disable the transaction management within seam, the old features of the application work fine however I can no longer get hold of the entity manager or persistence context.

Whenever I enable the seam transaction management I can perform all the persistence functions however, the old features will always throw an exception indicating that the persistence service cannot be closed coming up to the root
exception:

You cannot commit with autocommit set!

Now my question is this, how can I disable the seam transaction management and still get hold of the entity manager?

The problem was solved by following this approach:

Changes in components.xml

<core:init debug="@debug@" jndi-pattern="@jndiPattern@" transaction-management-enabled="false" />

<transaction:ejb-transaction/>

Now I can use the @PersistentContext from within the application, but what if I want to use the entity manager because I would like to reduce the amount of usage of EJBs. Ideally I would want to inject the entity manager such as:

@In ("entityManager")
EntityManager em;

Any hints on this?
