Here is my problem: I need to create a (seemingly) simple front-end for a report. The user enters a bunch of numbers, seperated by whitespace or commas, which are the IDs that will be brought up in a report.

Hi all, I am new to Java EE 6 and working on getting a number of demo applications running finally. I have an application scoped bean that has a @Schedule annotation on it that should in theory trigger that method every minute. However, that method doesn't appear to ever be invoked. It simply writes to the logs that it was called. C...

Hi all, I have event observers which all observe the same event, so I have an abstract superclass which observes that event and then the subclass overrides / implements the specific functionality. The problem with this is that it doesn't observe the event unless I put the event observer method in the subclass (which defeats the purpose...
