In theory. an incremental republish is only supposed to copy over the files tht have changed since the last time you published. In reality, this doesn't work in webtools because it still needs to repackage your entire jar anyway. Marshall and I are in the process of completing a demo and some code for real incremental publishing into an exploded war / ear folder in your jboss deploy directory, so that a repackage / redeploy is not necessary for simple jsp / html changes etc. littlejoz: The only ideas I have right now are to check the event log in the jboss server's view which would hopefully contain info about why the republish failed. The CVS version, I'm sure, has a working implementation of the republish, but I'm sure that's no real comfort to you. I'd write more, but I need to catch a plane this morning, so I really should start getting ready. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026589#...
