If you are writing a small ejb3 app that is not separated by layers ( I dont want to fume the flamewar) you would create and initialize the entitymanagerfactory in your application object and create entity managers using that. This is the way to access entitymanager if you are not using the rest of the container.
In a bigger app you would inject your session beans into wicket application using jndi and gain access through them. -Igor > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Jonathan Locke > Sent: Monday, August 01, 2005 9:16 AM > To: [email protected] > Subject: Re: [Wicket-user] Hibernate/EJB3.0 > > > > [EMAIL PROTECTED] wrote: > > >I don't think you are disagreeing because I agree with both of you. > >There's something in the Java water that just leads to overly > >abstracted software...
