Basically, Javassist provides a byte stream of a modified class file. How it is loaded is the responsiblity of the clients such as HiveMind. Although Javassist provides a covenient function for loading it by a simple class loader, the clients should use their own class loaders if they need some application-specific requirements. Do you know how HiveMind load classes generated by Javassist? Thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963431#...
