New to Java

Hi,
I have this code:

ArrayList remoteEvents = new ArrayList();
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
...
...
...
remoteEvents = (ArrayList)ois.readObject();  //line 615

and when I compile I get this error:

[615] unreported exception java.lang.ClassNotFoundException; must be caught or declared to be thrown
remoteEvents = (ArrayList)ois.readObject();
^

I looked at the documentation for java.lang.ClassNotFoundException and I can't see why I would have to catch it in this line of code. I have other places in my file where I am trying to read in ArrayLists over the socket and that code compiles/works just fine. The only thing different about this code is that it is in the run() method of a thread.

Any ideas?


Thanks.
