Compile Java in memory

Is there a way to emit Java bytecode in memory and execute it? I know that there's JavaCompiler class, but I'm asking something like Reflection.Emit of .NET platform.

You need to play with the class loader to load dynamically some class. There are some interesting SO questions on the subject:

This is possible but this requires the end user also to install JDK. Compile the bytecode to memory and create a new java process and start it. You can also execute java source directly.

See Beanshell2.
