Re: [Springframework-developer] declarative rules-based bean validator w/ attributes in sandbox

[Keith D. <kd...@cs...>]

Correct me if I'm wrong, but I don't think there is.  However, I know if
you're using Eclipse, the sandbox code (including tests) automatically gets
incrementally compiled in target/other-classes, which is automatically put
in the classpath.  So I have been basically running everything in the
sandbox from Eclipse directly.
