Hi Glenn,
To expand on what Rani said, there are certain classes and methods which
were done one way in JDK 1.0.2 and have been dramatically changed in 1.1 .
When you get a deprecated warning on a class/method the compiler is
telling you've used an old way of doing things which is in the process of
being phased out. Specifically, the message you're getting is reflecting
the fact the most significant thing that changed between JDK 1.0.2 and 1.1
is the way events are handled. 1.1 has a much simpler, more efficient way
of handling events where instead of passing event up the stack to be
handled, you implement listener interfaces which catch the specific event
types you're looking for. As Rani said you must be using code or a book
which is using the 1.0.2 event model. It will still work fine (for the
time being), but you'll get those deprecation warnings.
For instructions on how to upgrade your events to 1.1 style see.
