OT 32/64 bit classes

Title: OT 32/64 bit classes






Hi,


We will shortly be moving over to a 64 bit JVM from a 32 bit one. My question is, are the classes the same between 32 bit and 64 bit? or do I have to rebuild both tomcat and the application?

Ta

Matt

Every JVM on this planet uses the same Java ByteCode, which means that 
there are no 32-bit or 64-bit Java Classes, just Java Classes. I've 
run Tomcat on both PC/Linux (32-bit) and Alpha/Tru64 UNIX (64-bit), no 
problem.

Nix.

This is not really true ;-) 
The java byte code depends on target option for javac ;-)

Aha. Yes, but it has nothing to do with 32/64-bitness. I believe that 
backward compatibility is OK.

Nix.
