Yes but IIUC this makes it rather iffy for anyone who wants to use the multicast discovery(?) stuff in activemq -- they have to find the appropriate jar themselves (which one????) and decipher the licensing which is far from clear at the moment and figure out how to get it into the appropriate classpath. Also use of the javax.jmdns classes in activemq code might possibly annoy sun. I already did (2) locally, it only took about 15 minutes. thanks david jencks > > On Sat, Apr 5, 2008 at 3:47 AM, David Jencks > wrote: >> While reviewing the legal files (LICENSE and NOTICE) for activemq >> 4.1-SNAPSHOT I discovered that the build depends on and the assembly >> distributes a jar activemq:jmdns:1.0-RC2:jar.
