[Advanced-java] On the fly compile

I'd probably start with:
    http://bcel.sourceforge.net/ ByteCode Engineering Library
or  http://www.beanshell.org/ BeanShell
or  http://www.gnu.org/software/kawa/ kawa - gnu.bytecode
and more...

in case if true "compilation"(=.class file geneation) is _not really_
needed, things like below may do nearly the same:

 | import bsh.Interpreter; // BeanShell
 | public class A {
 |   public static void main(String[] args) throws Exception {
 |     new Interpreter().eval("System.out.println(\"hello world.\")");
 |   }
 | }
