I am using Rhino for one of the Web applictions to run js on server side. I can improve the performance significantly by pre-compiling the js to java. What it means is, from time to time, based on user action, I would like to compile the modified js scripts and convert them to java using Js->Java compiler and deploy them to Jboss server directories. I have never been a big fan of hot deployment of classes in App servers. But, currently I have a real use case, where it would benefit me doing so. I really need Jboss experts advice here as to (a) Does Hot deployment in Jboss 4.2.2 work? is it reliable? (b) is there a specific classloader adjustments I need to do to make it work? (c) What are gotchas I should be careful about or work around them? Please reply.. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161354#...
