is there a way to force a transactional rollback without encountering an exception?

Question

I have a method that does a bunch of things; amongst them doing a number of inserts and updates. It\'s declared thusly...

@Transactional(propagation = Propag

Call setRollbackOnly() on the SessionContext if you're in an EJB.

You can inject SessionContext like so:

public MyClass {
    @Resource
    private SessionContext sessionContext;

    @Transactional(propagation = Propagation.REQUIRED, 
                   isolation = Isolation.DEFAULT, 
                   readOnly = false)
    public int saveAll(){
        //do stuff;
        if(oops == true) {
             sessionContext.setRollbackOnly();
             return;
        }
    }

setRollbackOnly() is a member of EJBContext. SessionContext extends EJBContext: http://java.sun.com/j2ee/1.4/docs/api/javax/ejb/SessionContext.html Note it's only available in session EJBs.

@Resource is a standard Java EE annotation, so you should probably check your setup in Eclipse. Here's an example of how to inject the SessionContext using @Resource.

I suspect that this is probably not your solution, since it seems like you may not be working with EJBs -- explaining why Eclipse is not finding @Resource.

If that's the case, then you will need to interact with the transaction directly -- see transaction template.
