Re: problems with hot redeployment under jetty6 (maven2)
Burkhard, First, as someone else mentioned, please post this on the [EMAIL PROTECTED] However, while we're all here What is going on inside the login jsp? Looks like some instance of a class that is loaded by the webapp class loader is being set on a class that is loaded from the system classpath. This would mean that the class that is loaded via the system classpath never changes with a webapp reload, but the class from your webapp will change with every restart (because the classloader is different, so you'll get ClassCast exceptions). regards Jan Burkhard Graves wrote: Hi folks, I'm using the maven-jetty6-plugin (6.0.0beta14), usual Maven defaults.
