It's not just the code compiling, it's understanding how the thing works.
For instance I now know that I don't need to manually change the server.xml
file to deploy applications. But I still don't know why /hello works, and
hello/ or /hello/index.jsp does not.
A tar'd example with all the directories in place eliminates mistakes of
directory structure and shows the requirement to get <servlet>.class into
WEB-INF/classes. But, I still don't know if there is a way to undeploy an
app in the same way that all needed files are deployed. Seems like an
application server would have a remove feature in place or on the
improvements list.
When I first started using Apache to manage sites I was just as lost in the
beginning. But, the docs on Apache covered every single line in httpd.conf.
Once I got the server up I could experiment with what would break/improve it.
As I mentioned in an earlier post, I would love to learn every quirk and
optimization in JBoss-Tomcat. But, what I really need is to get it to serve
up pages right now, which is 25% of what I need to accomplish.
A JDBC-MySQL 'hello world' would solve another %25 of what I need.
How about a 'hello-world' for sending email?
Last, a How-to on hot-swapping applications would be good. I need to know
if I can send people to an error page if an app has been removed for
instance? I'm sure this info is in docs or newsgroups some where but I
don't always have time for marathon learning binges.
Many folks just need a webserver/app server to out send out HTML, merge
data, maintain apps, and send email. Four 'hello-world' examples and were
happy.
Why it works is a matter for another time. Just give beginners examples
that work with a completely vanilla install and we can improve our
knowledge over time.
How this benefits the creators of JBoss is we can roll out JBoss Apps on
just about anything that will run Apache. That starts to make JBoss
ubiquitous and opens the door to high level consulting and EJB component
libraries.
Hell I'd pay now for a 1-2-3 setup for a MySQL/JDBC connectivity EJB
installer. It's trading 'work right now' for time to learn later.
As a matter of fact some of my partners are kicking around the idea of a
stripped down Red Hat distro that comes up with Apache, MySQL JDBC,
JBoss-Tomcat and management console ready to go. Just add Sun's JDK/JSDK.
I'm running my tests on a Pentium 166 with 32 megs of RAM. It's a junker
machine, but everything works just fine. Can you imagine providing
WebLogic-like functionality to webmasters in a $50 package that will run on
anything?
Thanks for all the help and on behalf of the newbies, I swear I'll reach
back and help once I've got the hang of things.
