java.lang.Compiler?

I'm trying to write a program that loads Java source by class name, compiles it and executes it dynamically.  The problem I an having is that the compiler portion of the code doesn't seem to work.  When I attempt to compile using the java.lang.Compiler class, I get a failure to compile.

Has anyone used this class?  Can you provide some source?

As I understand it the class java.lang.Compiler is for JIT
(Just In Time) compilation to native machine code not for
compiling source to bytecodes. If you are using JDK you can
compile using sun.tools.javac.Main. Here is a code fragment
to do that:
        /* error messages go to System.out, the tool is javac*/
      Main compiler = new Main(System.out, "javac");
        /* comp_args is a String[] of args to javac */
      compiler.compile(comp_args); /* compile it */

      /* load the class YourClass  that was just compiled */
      Class temp_class = Class.forName("YourClass");

      /* finally instantiate */
      SomeInterface object = (SomeInterface)
                                temp_class.newInstance();

This only works if java.tools.javac is available. It is
part of JDK but not part of the java core and may not be
in third party systems.
