Java developers

Greetings,

I was hoping one of you might be able to shed some light on an Issue I am having.

When attempting to use servlets or beans to forward a request a certain URL, it works, however the URL in the browser does not change and if you hit refresh the app bombs out since the data is no longer available. Is there anyway that you guys can think of to set this straight so that any URL the servlets map to after a process is finished and you hit refresh on like a congrats page it doesn't try to repost the data?

Using something similiar to:

this.setDestination("http://www.urlhere.com/blah.jsp?target=whatever&randomID=1");

etc... in the the instance I am speaking of the extendedprocessing uses processor as an arg and I say proc.setDestination etc

Thanks!

Does anyone know if D.J. Bernstein's recently discovered timing vulnerability in AES encryption affects the Java (1.4) implementation?

The vulnerability (at first, naive glance) seems to arise from speed optimisations in all fast implementations, for example, in C (causing some computations to be faster than others and therefore giving clues to the AES key by how long some texts take to process compared to others) but I wonder if Java, being slow and garbage collected, is less vulnerable than a "good" cryptography platform? If you need 200 million samples to break a key I don't think my beast of a Java program has much to worry about.

Just bought Thinking In Java....unfortunately the CD is cracked :( What a PITA!!

Don't suppose anyone has this book and is willing to send me the first couple chapters from the lecture dir to hold me over until the replacement comes on Tues.?

if so....
