Hi All, Please verify the below exception handling scenario.
Struts Action class --> Business Delegate --> EJB (Uses OR Mapping Top link to talk to database) Also, we have a ServiceLocator class which is used to get the EJBHome reference. There are three layers at which we need to handle the exception. At EJB layer, at business delegate and at struts layer. EJB layer (session bean) methods will throw the (Application) business exceptions. At business delegate layer, application exceptions will be thrown by methods, same as EJB methods. At struts layer, in the Action class's execute(), we will catch all these business exceptions. For Runtime exceptions, we will catch the ToplinkException (this extends RuntimeException and this is root of all runtime exceptions) in ejb methods and this catch block will throw SystemException (a checked exception). Action will catch this SystemException. Please provide your valuable inputs. Also let me know where EJBException will come in picture? Thanks in advance.
