Introduction

There are a few approaches to integrate OpenEJB and Jakarta Tomcat. The difference between them is in the visibility of EJBs (deployed onto OpenEJB) amongst web applications (deployed onto Tomcat). The term visibility means what classloaders handle loading of the EJBs.

• OpenEJB per Tomcat instance - (0.9 or higher) deployed EJBs are shared amongst all of the web apps
• OpenEJB per webapp - (1.0 or higher) deployed EJBs are visible only to the web apps that declared to load OpenEJB
• OpenEJB Tomcat resource factory - an implementation of Tomcat's resource factory mechanism
