I am trying to setup the spring batch project (2.0M4 version) to run with grails (1.2) I wanted to get the sample stuff up and running, so I created groovy files out of the various sample files that came with spring batch. Unfortunately, the sample files use Java inner classes, which groovy can't handle yet.
For now, I will just make these Java files, but I was a little surprised since I thought just about any syntactically correct java file was a valid Groovy file. Guess again. You learn something every day.
