I like the HEAD FIRST series.

HOwever, I am having a problem finding what RI is(I guess an J2EE app server, but I can't find it on the net to download).
Or even when I compile my 2 interfaces and AdviceBean class I get 8 errors, package javax.ejb does not exist, EJBObject, SessionBean, SessionContext....

What am I doing wrong here? I have tried installing earlier versions of SDK and J2EE versions but problems are still there.

ANy help would be appreciated.
