Sergio,
Best of luck in your effort choosing an application server. Despite
increasing standardization, it is still not an easy task. A big part of my
job is to help people evaluate our product, GemStone/J. Let me tell you -
even the 'simplest' app server will have some particular issues with the
infinate number of system configurations. Getting your first bean to run
may not be painless, particularly if you install multiple products on the
same box - we tend to inadvertantly interact with each other. Weblogic
Server and JRun are good products, and you shouldn't loose heart because of
what are likely simple configuration/typographical issues.
GemStone is, admittedly, one of the harder app servers to understand. When
you evaluate GemStone/J, your Systems Engineer will suggest/provide some
'HelloWorld' type examples that will best suit your intended use of the
product and help you get them running in your environment. There are so
many different architectures you can run on the product (almost all of them
adhering to Java standards)that getting your first one running can be
confusing. I see this as a necessary evil towards a beneficial end. Our
customers appreciate and utilize the flexability, and once they learn the
product, I think they are some of the most loyal customers in the industry.
The point to my message, if I would hurry up and get to it, is that you need
to consider the long term factors more seriously when evaluating an
application server. How will it adapt to my needs? Will it scale? Will it
be supported and stay up to date with standards? What is the ease of use
and capabilities of the product in a PRODUCTION environment? How much
hardware will it need to meet my needs? Will it handle the complexity of my
application?
No one vendor has the monopoly on all of the factors that should affect your
decision, despite the fact we each claim to be best at them all :^) Take
some time to consider what is really important to your business sucess. On
behalf of my bretheren vendors (if I may), I appologize for the difficulty
you may have getting your first bean to work. We would all like to have the
most impressive 'first experience', since that would help make sales easier.
But, the nature of computers makes this difficult, and our engineering
departments at times have more serious matters to attend to.

Subject: Please help me choosing an EJB server !!!
Hi List,
I want to dive into the EJB world, however I have to first familiarize
myself with an EJB server.
What I expect from an EJB server is: (comments are welcome)
-It must be free or It must have a full evaluation version. I cannot spend
millions on something I don't know how to use yet.
-It must be easy to deploy and test EJBs, in other words, It should have a
step by step guide to install/run the server and to deploy and test your
EJBs.
-It must have a descent future in the Application Server market. In the long
run, I don't want to be a specialist in something nobody uses.
I am considering: JRun, Gemstone or Weblogic.
I got Weblogic and tried the beanManaged example. It is something like a
HelloWorld example. I did what they tell you in the guide, however I keep
getting a JNDI error. My bean is registered with the right name and
everything. Have no clue what's happening.
I tried JRun. Did not have much success either. :-(
Did anybody succeed running HelloWorld's in these servers ???
What about GemStone ??? Is it easier ???
Thanks for the help, list. I just want to take the right first step.
Sergio Oliveira Junior
