Meta programming is a popular buzz word these days . There is a framework for java , called EMF (Eclipse Modeling Framework ) that tries to add that support to java . The framework makes meta programming look like total crap . It overly complicates stuff to such a large extent that you just feel like just removing it from your project code.
So in short meta-programming in EMF + java = night mare :(
But on the other hand if you are building your domain layer . EMF is a pretty decent choice . It has in build support for a notification mechanism that allows you to listen to various model changes . So your GUI can become lightly couple to the domain layer and can become very responsive .
If other people have tried EMF , i would love to hear their experiences.
