Passing the TCK - thats the trick. Given that most (all?) TCKs require that the public interface conform exactly to that which is specified and that JSR47 is not made up of interfaces but instead made up of classes it would be difficult to pass the TCK if you added anything to it. You could create new output targets/appenders/whatever but they could not be in the java.** namespace. JSR47 should not be considered in the same category as the servlet/JMS/ejb specs - more in the same category as the Collection API. -- Cheers, Pete *-----------------------------------------------------* * "Faced with the choice between changing one's mind, * * and proving that there is no need to do so - almost * * everyone gets busy on the proof." * * - John Kenneth Galbraith * *-----------------------------------------------------* -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
