Right now the CommonsValidator class in shale looks explicity for a validator-rules.xml in /WEB-INF/. It might be nice to add support for picking up a validator-rules.xml from a jar files /META-INF directory, like what is done with faces-config.xml. I think this approach may be flawed because if I am not mistaken commons validator only supports 1 validator-rules.xml, and jsf supports multiple faces-config.xml. So I guess you get into trouble if more than 1 jar on the classpath has a /META-INF/validator-rules.xml. You could pick the first one encountered, but that is probably not the best solution. Is there any precedant of loading from a jar, or has it always been put the rules in /WEB-INF? Thanks, Ryan
