HOWTO: install a Tomcat web application on Fedora 7 [was: ...]

Here are some instructions that hopefully will be of use to future users:

   1. To install tomcat on Fedora 7, just run "yum install tomcat5
      tomcat5-webapps tomcat5-admin-webapps".
   2. Your configuration files are in /etc/tomcat5. You may need to edit
      server-minimal.xml to set the port that Tomcat listens on. You
      will need to edit the file tomcat-users.xml and add a user with
      the role 'manager' if you want to be able to use the Tomcat
      Manager application.
   3. You can start and stop Tomcat by running '/etc/init.d/tomcat5
      start' (or stop,restart, etc).
   4. Any Tomcat web application that you want to serve should be
      dropped into /var/lib/tomcat5/webapps/
   5. You can view your Tomcat website via
      http://yourserver.example.com:8080/.

This webpage had some good instructions:
http://www.weiqigao.com/blog/2007/01/14/tomcat_5_on_fedora_core_6_in_five_easy_steps.html

I have often felt that Java developers, with their 'completely platform
independent' system don't acknowledge that platform-specific knowledge
is often a barrier to getting those Java applications up and running.
The above steps make maximum use of the packaging work that Fedora and
JPackage maintainers have done, and made this job very much easier for
me than downloading the platform independent packages and working out
their particular conventions etc.

Cheers
JP

RE: HOWTO: install a Tomcat web application on Fedora 7 [was: ...]

Posted by "Lessie Z. Mitch" <le...@hawaii.rr.com>.
I have to go with Gabe on this one.

I recently relied on a hosting vendor to 'configure tomcat accurately' in
Linux, and what a nightmare!

The problem is that TC is so customizable. Depending on your school of
thought, you might like the distro version - or you might like the project
version of install. If you like Linux, and are a Linux admin - using the rpm
would suit you fine. However, not everyone is familiar with Linux - some of
us are straight TC administrators. Then again some of us are just web
jockeys who are suddenly flung into the administration world. *waves*

I have found that due to some webapp dependencies, linked files cannot be
used accurately in some TC setups (as the rpm of Tomcat does - linking files
sometimes 10 levels deep!). For a person who is not a Linux admin, tryig to
configure a TC app with files linked everywhere is highly frustrating and
confusing. Top this off with an OS distro that is fully integrated into the
OS - where are the libraries again? What happened to that jar file? What do
you mean the JVM is not running??!!? TC winds up as a 'linux user' and as
such needs special permissions - and then cannot access log files, config
files, and woe to me, its own files!!!

I finally convinced hosting vendor to totally rebuild the server so that I
can then install the native (what I call encapsulated) TC. Everything is
there, where it should be, and usable by my webapps with the right
permissions (having been installed by the TC and not some rpm).

It is a matter of familiarity. I am familiar with the standard TC project
install that does not rely on any OS for functionality. It is modular, easy
to locate, and wonderfully portable to something else.

The concern that some of us on this list has with the various Platform 
specific distros, is that they are usually altered from the
original Apache distribution. As soon as anything is altered, you have 
incompatibility issues.

Most applications are developed and tested on the Apache distributions.
You may not notice incompatibilities until you try to deploy a real 
complex application.

That said, I am not saying one is right or wrong. It is just that just 
as Java has become relatively stable (predictable), there
enters the various Linux based distros to add to the equation. Some of 
these distros do not
follow the generally accepted JAVA programming principles (what is 
acceptable today).
These distros usually follow the principles of traditional Linux based 
programming, such as PHP, Python, etc.
And that is primarily to make packages globally accessible on the 
system. This is where the distinction between
traditional linux applications and present day java applications are 
being missed. Most Java applications
are dependent on a specific version of an application server, JVM, 
libraries, etc. Thus a one package
for all creates issues.

So moving forward, are Java Applications now to be built for a specific 
Linux distro, in addition to supporting the traditional purist
java programming environment. Or is it that a new generation of java 
programmers under the Linux distro environment will
give raise. Will there then be two camps or platforms? Or will the new 
generation become the standard. I say this because
as I speak, more and more I see java questions on Linux lists instead of 
pure java lists.

I know I do not usually rant, but this is an issue that needs to be 
addressed.
