hmmm, I've thought about implementing something like this several times myself.... but I don't think you need to modify a JVM to achieve that, you can just execute a "loader" class that than knows your "source path" and has access to a nice compiler and does compilation at class loading time. or am I wrong? -- Stefano. --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
