Why not use Java Preferences. Java Preferences is the way to go, but you need to provide a mechanism to manipulate them (whereas with property files you can simply use an editor). Ideally this mechanism is within your webapp, but you need to ensure that it can work with potentially Really Bad values in the preferences (i.e. if your property editor part breaks with bad properties, it's kind of hard to fix them, eh?). A notable scenario being I forgot my admin password or something else. One thing you can do is to put a reset directory in the top level of your WAR, then put a ResetProperties class within there (in the reset package, of course). Then, in your webapp protect the reset url with an invalid role. Finally, when the user needs to reset their preferences, they can simply do: java -jar WebApp.war reset.ResetProperties and it will set the preferences to reasonable defaults. A WAR file is simply a JAR file, so this should work just fine (I haven't tested it). You protect the reset path so that it can't be downloaded over the web. The reason you jump through these hoops is because the Java Preferences stores its values differently on different systems. Notably it uses the Registry on Windows, and a file on Unix (in the users home directory). But, rather then fighting that, you can provide something that will work consistenly across platforms by leveraging the API and Java.

RE: Application configuration
Larry,
I forgot to include Tomcat version number which is 3.2.2 Even when I created
the directory, I guess I need to indicate tomcat how to resolve the classes
needed.
Here is the scenario:
1) Directory where all the classes are located is {server}imr/servlets
2) From here I can see the list of servlets
3) If I click on one or two of them I receive a download file screen with
options to open or save the class.
4) If I select to open the file from it's current location, I receive a
message saying Could not find the main class. Program will exit!
About log files mmm, I just have jasper.log and servlet.log files
under logs directory. Any of them indicates anything related to the problem.
Cheers,

You still haven't indicated which version of Tomcat, so it
is hard to make specific recommendations.
For all 3.x and 4.x Tomcats, creating a subdirectory under
the webapps directory is the simplest way to bring a new
web application online. Tomcat will automatically serve
these subdirectories without requiring config file changes.
You seem to have done this.
However, I can't tell much from I don't even reach the point
where Tomcat itself is running my application. What
error is reported when you try to run a servlet? What do
you see in the log files?
Cheers,
Larry
P.S. If you are not familar with the Servlet specs, you
can download it from here:
http://java.sun.com/products/servlet/download.html
Tomcat 3.x implements Servlet 2.2, Tomcat 4.x implements
Servlet 2.3.

The configuration you show only lets Tomcat execute
servlets. All other content, Apache will try to serve
directly. Is this your intent? It would also help
to know which version of Tomcat 3.x you are using.
(Note that Tomcat 3.3 does the best job of automating
the connection to Apache.)
In general, I would also recommend testing your web
application first by accessing Tomcat directly. If
everything works okay, then try accessing through
Apache. A web.xml isn't required as long as you are
happy with what Tomcat provides by default.

I think I reach that point where I need some help ... could
you subscribe me
and help me with the following issue.
Totally new in configuring applications to be deployed on tomcat:
1) Apache and tomcat are running perfectly
2) I created a directory to install my application (webapps/imr)
3) Under that, I created META-INF, WEB-INF and servlets directories.
4) I also modified tomcat-apache.conf as follows
Alias /imr /home/jcamara/tomcat/webapps/imr
Directory /home/jcamara/tomcat/webapps/imr
Options Indexes FollowSymLinks
/Directory
ApJServMount /imr/servlet /imr
Location /imr/WEB-INF/
AllowOverride None
deny from all
/Location
Location /imr/META-INF/
AllowOverride None
deny from all
/Location
5) I'm starting to believe that I need to create a web.xml
file and I'm not
sure how, probably I'll follow one of the examples.
6) I can see the list of classes for my application under
that directory.
7) Every time I'm trying to run the application it asked me
for download the
application on IE and finally come with an error saying
Could not find the
main class. Program will exit! on a Java Virtual Machine pop
up screen.
I'm 100% sure that I'm missing something, so here are my questions:
Q1: Do I need to create a web.xml file?
Q2: Where should I put the jar files that my application need?
Q3: How should I configure Tomcat in under to display correctly my
application?
