    Release Notes: The main features of this release are the reworked Struts 2.x plugin and the brand new Struts 1.x plugin that reloads changes to Struts action mappings on-the-fly both from XML and Java 5 annotations. Developing Struts applications with JRebel is now easier than ever, as no restarts are necessary anymore. This release also includes support for GlassFish v3 and the Felix OSGi container on which it is based.

      Release Notes: Packaged deployment. Very low performance overhead. Better startup time. Spring, Guice, Stripes, Tapestry 4, and Struts2 reload out of the box. Better compatibility. IBM WebSphere and Groovy are now fully supported.

        Release Notes: This release improves the initial class loading and initialization to the point where startup with and without JavaRebel shouldn’t be noticeably different anymore (the instrumentation time for one class is under 5 ms). With per-application rebel.xml configuration files, you can develop applications deployed as WAR or EAR as if they were fully exploded, without any intervening build process. The compatibility layer has been rewritten largely from scratch to completely mimic uninstrumented Java classes. This should ensure that anyone can take JavaRebel and start using it in minutes without any problems.

          •  13 Dec 2008 18:57

            Release Notes: This is a minor update to the stable branch that fixes a couple of issues that were reported since the previous release. It also adds support for JBoss 5.
