I want to compile multiple java files in my Application without restarting Weblogic and Tomcat. Otherwise, this takes a lot of time. For this I got one Hotswap plugin in Eclipse, but this is not working in all the cases. It says it works for single file compile. Even if I use that it is not working in all the cases.

Is there any other way that I can do this or is there any other plugin/script/software which can help me in this?

If there are some open source ones, it will be very helpful.

Thanks in Advance.

  1. One thing is compiling the classes, but you also need the JAVA VM to reload the classes and use them, which is called hot-swapping. For the best available hot-swapping of classes you’ll need something like javarebel. It allows you to hot-reload a lot more types of code-changes than the regular SUN JVM. If you run your deployment in exploded-mode you’re home free, and can test any code change in a second or so. We’re fairly test-driven, so I only use javarebel in that short phase when I assemble the whole application, but it works really well.
