I'm sure one could find a reason, but usually one would choose either
a Java servlet container (like Tomcat) or a Java EE server (like
Glassfish). If you like Tomcat and your EE needs are minimal, take a
look at TomEE, which is a Tomcat core with a bunch of Java EE services
available on top of it.

TomEE would be more of a competitor to Glassfish than Tomcat would,
because Tomcat has only the servlet, EL, and JSP specifications
implemented from the Java EE collection.

Hello all,
  Recently, I downloaded Java EE with the SDK.  When I went to
install it, it could not find the Java Run-time, the JRE.  I have Java SE
with the JDK installed and have used Java on my system.   When I installed
Java SE it included the JRE. Perhaps the problem is that I have Java SE
1.7u51 and the latest version of Java EE is 1.7u45, I believe.  So, I guess
when installing Java EE, the installer expects you to already have the Java
Run time installed?
  Next question is with regard to the server.  Is there any
reason one would run both Tomcat and Glass-Fish server?  I'm not really sure
what the differences between these two are.  Also, there is the issue of
ports.  When I installed Tomcat it runs on port 8080 (and a couple other
ports).  In a production environment one doesn't typically see the port
specified in a link.  Do we serve web pages using Tomcat on port 80 in a
production environment or how is this handled?  You can't have two servers
running on the same machine using the same port.


8080 is the default, but if you want to change it, it's as easy as 
changing a setting in server.xml and restarting.  Yes, 80 is typically 
where you'll put it if TC is providing your default http services.  If 
you have another http server (IIS, Apache HTTPD, etc), then you have to 
deal with the conflicts somehow.  TC works fine for serving static web 
pages, so the others aren't necessary unless you need something from 
them that you can't get from TC.	


Sorry, I can't help you with the other questions.



Thanks,
Bruce
