是否有任何可放入非j2ee Web服务器的独立EJB容器？

Question

Right now I am using a web-server which does not contain EJB container. If my application needs EJB container, how could I add one?

Answer 1

OpenEJB and EasyBeans are open-source EJB containers that can be dropped into Tomcat or other servers / applications.

But, you should describing what you need this for... because if you need EJBs specifically, you're probably better off going with a full app server (JBoss, Glassfish, Weblogic, etc.). If you're just using it for persistence, you're probably better off using some other persistence technology (Hibernate, iBatis, etc.).

Answer 2

Do you really mean into ? If yes, then maybe have a look at OpenEJB (the EJB Container implementation for Apache Geronimo). But I can't say that it's widely used.

Actually, why not just replacing your servlet container with a full Java EE server if you need EJBs, I don't get it, something like JBoss AS or GlassFish.

Answer 3

JBoss is an open source J2EE server. So if for some reason you can't just use it, you could take the EJB container and graft it into something else. Probably not a small job.

Answer 4

Too litte information on your architecture to give a decent answer.

Anyway chances are good you already apache as web server, you can simply connect using mod_jk to the embeddd tomcat in jboss. This configuration will use the Apache JServ Protocol (AJP) for communication between Apache and Tomcat.
