If you have read my previous blog post about How to Hotswap classes in the running jvm, I am sure you will find Java Rebels even more interesting. It supports full class reloading support at runtime with method refactoring and all the stuffs that hotswap.jar could not do. Trust me, Java development has never been more fun. And if you are into spring development, it even supports spring configuration reloading without restarting the whole spring application context! Could it be better!!! I think its a must have feature for every java developer. I don’t know why sun is not incorporating this in the JVM? Just because java is not a scripting based language like php/ruby , doesn’t mean we can’t have fun like those guys! Speaking of fun, you can have some from this Java Rebel cartoon also

Only downside is JavaRebel is not free. There is a small fee that you have to pay. But let me tell you its worth it. And if you don’t trust me, you can always use the 30 Day trial version (although it will only take 3 days for you to become addicted to it).

NOTE: I don’t work for java rebel.I wish they took me in 🙂 it would be fun to develop such cool features that eases the life of so many developers.
