The latest expert opinions, articles, and guides for the Java professional.
- Packaged deployment. We now support deployment as WAR/EAR with exactly the same feel that exploded development has. All the classes and resources will be reloaded on the fly as soon as you hit Save. All you have to do is create a
rebel.xmlconfiguration file that will tell JavaRebel where to find the updated classes and resources. On top of that we now provide a Maven plugin that will do this configuration for you!
- Very low performance overhead. The performance of the application with JavaRebel enabled is now pretty much the same as without JavaRebel.
- Better startup time. Application or server startup time should be much nearer to the usual one, though there still is more work to be done when starting with JavaRebel, so some slowdown is expected.
- Spring, Guice, Stripes, Tapestry 4 and Struts2 reload out of the box. Plugins for those frameworks are now included with JavaRebel and allow configuration to be changed instantly, just as classes.
- Better compatibility. We’ve done a whole lot of work on making JavaRebel more compatible with Java projects in the wild. This involved making sure that Reflection API behaves 100% predictably, extensive test suites in many environments and lot of integration work. In particular AspectJ load-time-weaving, IBM WebSphere and Groovy are now fully supported.
