Hello folks:
I am working for J2EE and J2ee patterns. But the more
I learn, the more I feel confused.I am not sure if
J2EE is convinent and robust enough or just make
things more complicated. I tried the jboss online
petStore. It seems a traditional web applicatioin
though I think it is so easy. But when I what to try
sign in a new user, it seems has a lot of exception.
Looks like following:
Internal Servlet Error:
com.sun.j2ee.blueprints.petstore.control.GeneralFailureException:
Could not activate; nested exception is:
java.io.FileNotFoundException:
/home/petstore/jboss/dist/db/sessions/TheShoppingClientController/988941019417.ser
(No such file or directory); nested exception is:
java.rmi.NoSuchObjectException: Could not activate;
nested exception is:
java.io.FileNotFoundException:
/home/petstore/jboss/dist/db/sessions/TheShoppingClientController/988941019417.ser
(No such file or directory)
