If you have applications that can benefit from memory bigger thab 2 or 4GB,
your application is data intensive. H

I would discourage to use such machine! 8GB means you are using 64 bit
machine which will be much slower than 32 bit machines. Big memory is useful
ONLY if you have applications that can benefit big memory such as database
systems. In Java, if you use lots of memory and create lots of objects, you

This is quite tricky issue. I use the following method.
Basically it locate the directory where you place your
designated class definition!
static String base;
static {
try {
// use an object instance which is part of service!
my.package.MyObject rm
