I believe Eduardo is on the right track. You need to look into your
JDBC Code, I don't think it's doing what you want. One way to find
out would be to add:
System.out.println("Retrieved " + userList.size() + " users");
right before returning. You might also want to reconsider putting
your list in the Application scope, since you won't be able to support
more than one user at a time with that strategy.
