will ejb3 rePack my exception?

[chibi]

it seems EJB will rePack my custom exception with EJBTransactionRolledbackException, then add a message "Transaction failed " in facesMessages()

i have a EJB service like this:

public void doSomething() throws ServiceException{
 try {
 something_to_do();
 } catch (Exception e) {
 throw new ServiceException("sorry, i can't do this");
 }
 }

and i have a seam component use this service:

public doSomethingWithEJB(){
 try {
 ejb.doSomething();
 } catch (ServiceException e) {
 log.info("he can't do that #0", e.getMessage());
 } catch (Exception e) {
 log.info("huh? he throws a new #0 Exception:#1 ", e.getClass(), e.getMessage());
 }
}

when service failed, i got this result:

huh? he throws a new class javax.ejb.EJBTransactionRolledbackException Exception: sorry, i can't do this

my service is stateful and my seam version is 2.0 RC1
