Is Tomcat considered to be a J2EE implementation?
Hi, I've been coding Java for a while, and now I'd like to learn J2EE. I downloaded and installed Tomcat version 4. Is Tomcat a reasonably complete implementation of J2EE? That is, if I learn and use Tomcat, can I claim to know J2EE?

RE: Is Tomcat considered to be a J2EE implementation?
hello, The J2EE includes the following technologies : Servlets, JSP, JNDI, JAXP, JDBC, EJB, JMS, Java Transactions, JavaMail, Java IDL, J2EE connectors and Corba (am I missing something ?). Read all about j2ee and related technologies at http://java.sun.com/j2ee Tomcat is only a Servlet / JSP container... so while using it you´re not neccesarely using all the other technologies, so I would not say that you know j2ee untill you know at least half of em. But then again Servlets, and JSP are a very big part of J2EE functionality. I would say if you learn and use Tomcat, you can claim you know servlets jsp, and probably some of the other parts of J2EE. If you check out EJBs along the way u´re getting very close to knowing J2EE, at least you should know what to claim. hope that explaines it... --reynir -Original Message- From: Michael Davis [mailto:[EMAIL PROTECTED]] Sent: 15. desember 2001 16:14 To: [EMAIL PROTECTED] Subject: Is Tomcat considered to be a J2EE implementation?

Re: Is Tomcat considered to be a J2EE implementation?
Thanks, I've been using JServ to create servlets for a while, and I thought that the difference between simply using servlets and J2EE was that the latter has an EJB container. If this is true, then does Tomcat come with an EJB container? Or maybe a better question is, can you program EJBs with Tomcat?

If this is true, then does Tomcat come with an EJB container? Or maybe a better question is, can you program EJBs with Tomcat? Thanks again, Michael Try looking at, for example, JBoss. That is a j2ee enterprise application container that uses Tomcat (and Jetty, if you want) as the web container. The previous answer gave you everything you need to know. The answer was and is that Tomcat is not a j2ee container. Tomcat is a web container that handles jsp/servlet functionality. Normally, the j2ee functionality is not web client to server, but is server to server and various underlying APIs (as pointed out to you in the previous answer) to assist. In short, the last guy gave you a correct answer. Read it carefully and start checking out enterprise application servers, such as JBoss, etc. Hope this helps, but it really does not and need not add anything to what you already have been told. What you already have been told is the whole answer. Tomcat has no deployer for enterprise java beans.

Thanks, I've been using JServ to create servlets for a while, and I thought that the difference between simply using servlets and J2EE was that the latter has an EJB container. J2EE has a large number of technologies beyond the servlet and JSP support present in Tomcat, plus requirements on the container for configuring resources such as JDBC data sources. Tomcat 4 is a complete implementation of the servlet 2.3 and JSP 1.2 requirements, and supports a small subset of resource factories that are upwardly compatible with J2EE programming standards, but it does NOT contain any support for the extra technologies such as EJB. If this is true, then does Tomcat come with an EJB container? Or maybe a better question is, can you program EJBs with Tomcat? You will need an EJB container in order to program EJBs. Two approaches for you to look at: * Get the J2EE 1.3 Reference Implementation from Sun http://java.sun.com/j2ee. It embeds Tomcat 4 inside to provide the servlet and JSP technologies, and also supports all the rest. * Get an external EJB server that can integrate with Tomcat, such as JBoss http://www.jboss.org. It connects with Tomcat to provide the web layer, and itself provides EJB support.

RE: Is Tomcat considered to be a J2EE implementation?
No, tomcat doesn't come with an EJB-container. But you can plug in tomcat into an EJB-Container. For instance, tomcat is the Servlet/JSP-Container for jboss (http://www.jboss.org), an open source EJB-Container. And tomcat is the Servlet/JSP-Container for the J2EE reference implementation from sun. So, you see there is a big difference between an EJB-Container and a Servlet/JSP-Container like tomcat. So, when you use tomcat as a Servlet/JSP-Container for you EJB-Container (ApplicationServer), then you can access EJBs from your servlets and jsps... Hope that helped a bit. cheers pero -Original Message- From: Michael Davis [mailto:[EMAIL PROTECTED]] Sent: Saturday, December 15, 2001 5:48 PM To: Tomcat Users List Subject: Re: Is Tomcat considered to be a J2EE implementation?

RE: Is Tomcat considered to be a J2EE implementation?
no Tomcat does not come with an EJB container, but it supports the use of EJBs with in servlets jsp. But you can download Jboss, bundled with Tomcat... Jboss is EJB container/ application server. Try it, it´s very good. hope it helps, -reynir -Original Message- From: Michael Davis [mailto:[EMAIL PROTECTED]] Sent: 15. desember 2001 16:48 To: Tomcat Users List Subject: Re: Is Tomcat considered to be a J2EE implementation?

Re: Is Tomcat considered to be a J2EE implementation?
Thanks to everyone who replied. One big relieve is that you all agree! I'll get JBoss and try that out.
