Hi, I have been learning about servlets, JSP and EJB in Apache/Tomcat and Sun Application Server environment using Netbeans as the IDE. So my knowledge in Java quite limited.... I have been trying to learn about Websphere and Weblogic..... but I am confused. Is Websphere and Weblogic: 1. Web and/or EJB container 2. Act as a Server (like Apache) 3. Is a IDE too (like Netbeans?) If they are containers/servers then can I use them with Eclipse or JBoss? And also, what is the difference between Websphere and Weblogic? (As they both belong to IBM.) I have googled on this topic but unable to find clear understanding, please help Thanks, Danveer.
