rollback

[kabirkhan]

Transactions basically work as in previous versions of EJB

In ejb2.1 there was a setSessionContext method. The Container set the context. In any method one could use the context (ctx) to say ctx.setRollbackOnly. How could you do something similar using the ejb3.0 preview? Also in ejb2.1 when a method threw and EJBException a rollback occured automatically I believe. What would be the analogous thing to do when using ejb3.0 preview?

[kabirkhan]

In EJB3, you can make sure that the contaner injects the sessioncontext into your sessionbean, by either annotating the setter:

@Inject public void setSessionContext(SessionContext ctx) {
 this.ctx = ctx;
}

or the member variable directly:

@Inject SessionContext ctx;

This doesn't work in the latest ejb 3.0 that comes with as 4.0.3RC2.
What should we use now?

Thanks

I think it goes like this:

private @Injected EntityTransaction tx;
try {
...
} catch (Exception ex)
{
tx.rollback();
}
