Adobe (formerly Macromedia) JRun 4 was released in 2002. Since then, Java web development has moved on somewhat. JRun 4 supports Servlet 2.3 and JSP 1.2, while most servers are now on Servlet 2.4 and JSP 2.0. At four years since the last release, many developers assumed development of the server had ceased.
But now it looks like JRun might be set to rise from the ashes, with Adobe looking for beta testers of a major new release. At this stage, Adobe is tight-lipped on what new features will come with this version–EJB 3.0? Jetty-like continuations? More affordable pricing?
I’ve asked for a look at the beta, and will report what I can when I can.
