I like to know what are the differences between Tomcat container and Resin container
Tomcat is a stand alone web server supporting the J2EE web technologies (eg. Servlets, JSP) and Resin is a full blown J2EE Application server which includes a web server plus the rest of the J2EE family of technologies (eg. EJB). Tomcat is always free to use for any purpose. Resin is free only for open source or hobby use. Commercial use of Resin is not free. One interesting feature of Resin is the ability to run PHP applications under the JVM through Quercus.
