Drew Davidson, of OGNL fame (amongst other), has written an OGNL-based property configurer (BeanFactoryPostProcessor implementor) that evaluates OGNL expressions in <value>, <map> and <list> entries, etc in the Spring configuration.
I get to use OGNL whenever I am working on either of my favourite web frameworks for Java: Tapestry and WebWork2.
It is one of those small languages that does one thing, and does it really well. It is a lot more powerful than the EL.
So, I am excited to see the like of OGNL, and Groovy, for configuring and wiring my components together. Thanks for this work Drew!
