Vinay, JMX support will not be part of 1.1 RC1 - it is currently in the sandbox. There are no nightly builds for download. You would have to build (ant fulljar / ant sandboxjar) from a CVS snapshot - http://sourceforge.net/cvs/?group_id=73357 Thomas Vinay Aggarwal wrote: > > Hey Rob, > > Is this functionality going to be in 1.1RC1? > > Also to try it out I need the nightly builds.
