Q&A
| Q1: | What sort of state can stateless Session beans have? |
| A1: | Somewhat surprisingly, stateless Session beans can store state, but it must be independent of the client. A connection to a database or a reference to another EJB that is not specific to any given client is a typical example of client independent state. |
| Q2: | What is the prefix that will appear in all JNDI lookups? |
| A2: | The java:comp/env context is guaranteed to exist in a J2EE environment. |
| Q3: | How are EJB system exceptions different from regular Java exceptions? |
| A3: | A RemoteException can be caused by network problems, which, in the context of distributed J2EE enterprise applications, represent a system-level rather than an application-level exception. |
