Tim Okay, I'm gonna say this once and only once. Then you can use your favourite search engine for the answers the next time.
>1) JBoss Is a J2EE application server. (www.jboss.org) >2) Orion Is my favourite application server (www.orionserver.com) >3) Tomcat Is a servlet/jsp container/runner whatever name you want.(http://jakarta.apache.org) >4) J2EE Stands for "Java 2 Enterprise Edition", go look on the Sun site about it. >5) JNDI and Is the Java Naming and Directory Interface, something I know nothing about, but there is documentation at http://java.sun.com/products/jndi/ >6) JMS containers, in Java Messaging Service, more info at http://java.sun.com/products/jms/ >7) EJBs Enterprise Java Beans, http://java.sun.com/products/ejb/ >8) JSP Java Server Pages. For the record, there were some things I knew and some things I had to do a search on, but at the end of the day I composed this email in less than 5 minutes and used the search facility at http://java.sun.com to fill in the blanks for me. Now if I can do it, I'm sure other people can too. :) Kind regards Jason -----Original Message----- From: Tim Nicholson [mailto:[EMAIL PROTECTED]] Sent: 23 September 2002 09:22 To: JDJList Subject: [jdjlist] Re: J2EE, Tomcat, JBoss, etc. Can you explain what the following are :- 1) JBoss 2) Orion 3) Tomcat 4) J2EE 5) JNDI and 6) JMS containers, in 7) EJBs 8) JSP So what are these ? And can you recommend any learning materials (websites, books) for beginners in these technologies ? I am someone who is just starting to learn java and I don't know about any of these additional things ?
