Hi experts, Im working on some ticket booking system and had encounter something that i don't understand. Whenever i add create a Entity Bean, and if there is a existing record with the same primary key, it will throw me a TransactionRolledbackException. Everything works well if i throw the exception to the web tier(Servlet) and handle it. But i wanted to store some value into the Exception so that my Servlet can get it, i try creating a Customoize Exception that extends TransactionRolledbackException like this :
And the other thing im not sure is that in my EJB that use the entity bean. when i catch the TransactionRolledbackException , i must throw it to the web tier or i will get a error as if im not handling it. cant i just handle it silently at the ejb.
Thanks for reading. Hope someone will enlighten me
