Please answer the following interview questions. thank you.
1)What is the use of using entity(cmp/bmp) over session bean as session bean can also update the database tables using JDBC?
2)How to catch an exception thrown by ejb?i.e, if an entity bean updates the database and throws io exception while writing the status to a file, how to catch that exception in the client?
3)What is the use of session facade pattern?
