Transaction confusion

[dustismo]

Hello,

My end goal is to have multiple db transactions within a single action method
(similar to: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=107449)

I am using pojo with seam annotations, and I cant seem to get anything to work, and am getting very confused.

for instance, I want to create have a method that tests rollback:

@Rollback
public void testRollback() {
 EmailAddr email = new EmailAddr();
 email.setEmail("[e-mail]");
 this.entityManager.persist(email);
}

This is always commited?!? Shouldn't it rollback?

Ultimately I would like to do something like:

private void insertEmail(EmailAddr addr) {
//start transaction
this.entityManager.persist(email);
//end transaction
}

public void insertEmails() {
for (EmailAddr addr : emails) {
insertEmail(addr);
}
}

I've read everything in the forum, and in the hibernate book, but I still can't figure out how to do this. Any help?

thanks,
Dustin
