JBOSS V/s appache tomcat

Question

I am new to "java world", I need following clarification

• when to use JBOSS vs TOMCAT?
• differences?
• which is more reliable?
• which is more scalable?
• which is more easy to to administrate?
• does both have scale out options?
• can I host an application developed in flex on JBOSS/TOMCAT?

My application would be simple 3-tier with Servlets, so given this which is the best option.

Any comments/suggestions

Answer 1

They are different beasts. Tomcat is a pure servlet container (meaning can run servlets and JSP mostly). JBOSS implements thte full J2EE spec, adding, for example, EJB (Enterprise Java Beans) and JMS layers, with the additional complexity that entails.

You very likely just need a servlet container like Tomcat. I recommend Jetty as it's a lot simpler to handle for that use case (just servlets).

Answer 2

when to use JBOSS v/s TOMCAT ? differences?

Basically, they are web server but Jboss is a larger web server. JBoss is also used for enterprise applications using JEE technologies: JMS,EJB etc. and others like SOA, Webservices. Jboss usually is called Application Server (different from Web server).

which is more reliable ? which is more scalable? Both. It depends on your application

which is more easy to to administrate? Tomcat

does both have scale out options? Yes

can i host an application developed in flex on JBOSS/TOMCAT? Yes, any of them

my application would be simple 3-tier with Servlets , so given this which is the best option You did not mention what your tiers are so for the begining I suggest TOMCAT

Answer 3

Tomcat is a servlet container. JBoss is a J2EE container. It uses Tomcat as its servlet container. So the question doesn't actually make much sense.

Answer 4

my application would be simple 3-tier with Servlets , so given this which is the best option.

Use: Tomcat

Tomcat is a servlet container which basically serves JPS pages and servlets.

In the other hand JBoss is an application server ( which inside contains a servlet container among a lot more stuff ) and is more complex.
