Hello Patrick,
1) No, we don't bundle any application server with IntelliJ IDEA.
2) I don't quite understand what exactly you mean by this question. IntelliJ IDEA has a very good integration with the commonly used version control systems, and it also has a built-in instant messaging feature which also allows you to
exchange code snippets with your colleagues. If you mean some other feature, please describe what you mean in a bit more detail.
3) Yes, IntelliJ IDEA supports
Tomcat, Weblogic, WebSphere,
JBoss, Geronimo and GlassFish. You can register your existing application server installation in IntelliJ IDEA.
4) IntelliJ IDEA fully supports the
EJB 3.0 specification. You can find more information about our EJB support features at
