The
Lomboz J2EE Eclipse Plugin is supposed to allow you to define your own server definitions in case your favorite appserver is missing from the list of built-in configurations (
JBoss, WebLogic, WebSphere,
Tomcat). I haven't tried creating a definition myself, though, so I don't know how easy it is wrt Sun ONE.
Regarding your question about "suggested application servers", I usually suggest the following two products:
JBoss (open source, pretty large user base i.e. support, up-to-date APIs)WebLogic (market leader with WebSphere, nice tools and great documentation, up-to-date APIs, free development licences) [ July 11, 2003: Message edited by: Lasse Koskela ]
