Jaxer works alongside a web server to process content. Today, it can work with Apache 2.x using the mod_jaxer Apache module bundled with Jaxer. It can also already work with Java-based web server Jetty, using the jaxer filter servlet now packaged with Studio and soon to be available standalone. It also works with Tomcat (details coming soon) and will be compatible with other Java web and application servers. We'll be working to expand the range of servers with which Jaxer works closely: to Apache 1.3, to IIS, and to others. If you'd like to get involved in accelerating the pace of Jaxer connectivity, please let us know — that's the beauty of open source.
