In general, no -- in a typical project setup, any changes to Java code precipitate a rebuild and a restart of your application.
There are plenty of ways to avoid this, but currently, they're only used in the major IDEs when debugging (e.g. while debugging an application, you can usually make various changes to java code, and then load those changes into the running application without restarting). This is accomplished by bootstrapping the application with a custom classloader (or, more likely, many, many classloaders) that allows the IDE to replace bytecode at various levels of granularity (class, method, etc). In my experience, eclipse is much better at this than netbeans, although the latter should approach parity with the 6.7 release if I've read the tea leaves properly. I know of people who have used JavaRebel (http://www.zeroturnaround.com/javarebel/ ) to implement this kind of hot code reloading in a production environment; apparently, it works quite well. You could try using it yourself -- it appears to be free for personal and open-source development. How it will interact with clojure and the details of its classloader-related implementation is anyone's guess. - Chas On Mar 10, 2009, at 2:01 AM, Javier wrote: > > Hello, I'd like to thank you for providing us Clojure.
