With EJB3 the application server makes sure that your methods are executed within a transaction. This is not the case with Servlets so you have to start and commit the transaction yourself. Here is the code: | UserTransaction utx = Transactions.getUserTransaction(); | if(utx.getStatus() != Status.STATUS_ACTIVE) | utx.begin(); | em.joinTransaction(); | utx.commit(); | The if statement is not required however I needed that in my web application due to an exception that I don't recall right now.
