Hi all,
I have a question. What's the differences between J2EE engine and Jakarta Tomcat??
I've readed the introduction to j2ee (Creating a new web application) and i've seen that the directory structure of a web-site is more similar to a tomcat web-site structure..
Regards..
Eugenio.
Well relating to this topic i have one more doubt. If i create my applications using the Jakarta Struts. And if i am able to deploy them successfully on my WSAD to run on Websphere AS. Will it work on SAP 6.2 WAS?

Hello Eugenio,
There should be no real difference, except that Tomcat may not have all the J2EE components -- For example, if I remember correctly, you need to add on to Tomcat with JBoss if want to implement Enterprise Java Beans (EJB). But the underlying J2EE engines should be the same.

As Kevin pointed out, Tomcat is just a java servlet container which support java servlets and java server pages, and do not support other J2EE standards like EJB.
Normally, you deploy WAR(Web Archive) files to tomcat. For J2EE engines you usually deploy EAR(Enterprise Archive) which can contain numerous war files.
See http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Overview5.html for more info on ear files and their structure
