J2EE JBoss J2SE JSP JEB et al.

[Timie Milie]

I want to get into server side Java stuff and the seems to be a lot of
technologies out there.
I am a bit confused about how they all fit together.
I will be developing on a Linux system.

Sun's Java J2EE only appears to work out of the box on Redhat Enterprise
Server but it looks like I can develop JSP pages without Sun's J2EE
using Sun's J2SE and Tomcat. Is this enough? What are the main differences?

Is JBoss instead of Sun's J2EE or in addition to it?

Thanks in advance.

To use servlet technologies (such as JSP), it's enough. Tomcat includes that
subset of J2EE.

J2EE includes more enterprise technologies, such as Enterprise Javabeans.

Is JBoss instead of Sun's J2EE or in addition to it?

JBoss is an EJB container, which includes *that* subset of J2EE, so if you
install JBoss, there's no need to install Sun's J2EE as well.

J2EE is just a spec.
There are various implementations of that spec(JBoss,WebLogic,WebSphere
etc...)

If you use JBoss you get the full J2EE stack.

JBoss is more than an ejb-container, also other J2EE technologies are
included, like Tomcat for web-container functionality.

Jboss is tons more.... JMX, Axis Web Services, UDDI Services, JMS,
Hibernate containers, etc.

I should have said that JBoss is "foremost" an EJB container, as it is where
they really have succeeded in creating a good product, and where their focus
has been as long as I have known about it and used it.

As you say yourself, Tomcat is *included* with JBoss... ;-)

But you're right, the JBoss download is actually a complete application
server, conforming to J2EE standards.

But the conclusion remains the same, with JBoss installed, there's no need
to install Sun's J2EE as well...
