Does the minimum necessary to make writing Java based Model-View-Controller apps easy. It's not a huge framework that needs hundereds of pages of documentation. It's just a library that you call from your Servlets if needed.
What does libmvc do for you (and me)?
Routes HTTP requests to POJO controller methods Binds, converts and validates request parameters/fields Very terse Java based field definition Follows the DRY (don't reapeat yourself) principle No configuration files (XML or otherwise)
