1. Run your original code, i.e., *without* getTransaction().begin() and
commit. Since you are using an injected entity manager, you mst not use
getTransaction().begin() or commit().
2. See what SQL is being issued by TopLink Essential. You can configure
your persistence.xml [1], redeploy and rerun to see the SQL.

Frontend populates objected to be merged, is passed back to the webservice, the webservice calls em.merge(object) and then the frontend requests a list of those specific objects. The returned list reflects the changes but the database does not. Hence my conclusion that the transaction is not being committed.

>> em.getTransaction() is intended for Java SE environment. You shouldn't use em.getTransaction() in your session beans. Your session bean by default uses container managed transaction so each business method already executes in the context of a JTA transaction. If this method is invoked via its webservice endpoint, the container will wrap the method body with a transaction. Not sure why the tx is not committed. You may want to try add a em.flush() after merge, though it is not really needed.
