jCosmo

jCosmo is a Java source code "smell browser". "The jCosmo code smell browser detects code smells in Java source code that can be used to review the quality of the analyzed code and indicate regions that could benefit from refactoring." jCosmo runs on Unix/Linux. It comes with a Java to RSF fact extractor and Java domain files for Rigi.

Java to RSF extractor usage:
Run "javatorsf < directorylist > -o < outputfile.rsf >" where < directorylist > is a list of all directories containing source files you want to process. If you add the -u switch, the extractor will output unstructured RSF.
See the jCosmo homepage and instructions for more details.
