Q: Which is true about the client's view of exceptions received from an EJB?
1 Receiving an application exception communicates to the client that the bean will no longer be accessible
2 The client of a CMT bean can determine if the transaction has been rolled back by calling the getStatus() method of the java.transaction.UserTransaction interface
3 If the client receives an EJBException, the client must discontinue the transaction
4 If the client receives the java.rmi.RemoteException exception, the client will not typically know whether the method has completed

2> is my answer with the limited experience I had with EJB. If not could you please explain?

Q: In Java, how can I place three Components along the bottom of a Container?
1 Set the Container's LayoutManager to be a BorderLayout and add each Component to the "South" of the Container
2 Set the Container's LayoutManager to be a FlowLayout and add each Component to the Container
3 Set the Container's LayoutManager to be a BorderLayout; add each Component to a different Container that uses a FlowLayout, and then add that Container to the "South" of the first Container
4 Use a GridLayout for the Container and add each Component to the Container
5 Do not use a LayoutManager at all and add each Component to the Container
