hotspot

I am trying to speed up a program (without any additional coding effort.)
How do I get the hotspot (JIT) compiliation to work with the "java" command
in windows? I tried "java -server" but got

"Error: no 'server' JVM at ..."

I am using 1.5. Thanks for any help.

I assume you are using the Sun VM. Sun have included hotspot in all their VMs
since 1.2 or 1.3 (poor memory), so you will in fact be using hotspot already.
There is no need to invoke a -server option - the client VM does it too.
I'm not sure if the -server option still exists in 1.5 anyway.

IBM have included "mixed mode" which is a similar thing for a long time, too.
