Subject Re: Tomcat Setup and configuration
Date Tue, 06 Feb 2001 18:47:06 GMT
The intention ( in tc3.3 ) is to make all the configurations "explicit",
instead of using conventions like "webapps will be in home, libs in
install, etc". 

Even in 3.2 we tried to allow a shared installation dir and multiple 
work dirs ( i.e. you have one tomcat installed in /opt/tomcat, and each
user can run it with it's port and webapps ). This is not a "supported" 
feature - i.e. it's not very well tested or documented.

For issue #1, it's a bug - logs are "special" in 3.2 and they were not 
made relative to the home. The workaround is to use explicit paths.

In 3.3, the logs are corectly set relative to TOMCAT_HOME.

If nobody objects to the config changes I'll also add the ant-style syntax
for ${properties}, so you'll have more flexibility. Nacho started 
a nice idea in the loggers ( adding a ${TIMESTMAP} ), and I plan to add
other pre-defined properties (like configdir, context home, context
workdir ). 

Again - the current mechanism is indeed a bit confusing and complex, and 
making it explicit will be a big step forward ( i.e. all paths will use
${tomcat.home}/logs/mylog.log )

That's something I work on, but it's lower priority. ( better command line
support )

Issue #2 ( conf dir ) - again, in 3.3 most if this is configurable via 
individual module options. For example the apache.conf is generated by a 
module - and you'll be able to set the location to anything you want
( or any other properties that affect its behavior )

Henri proposed to make it simple to use Linux-style hierarchy ( with 
all logs in /var/log, configs in /etc/tomcat, webapps in /var/tomcat,
etc). Apache also have a "layout" option. 

Regarding Issue #3  - the web.xml is not used in tomcat3.2, 
and will not be used in tomcat3.3. All the server config
is done using server.xml ( and the new context.xml ) files.

There shouldn't be any overlap between web.xml and sever.xml,
any setting that is part of web.xml should be part of 
the web application's WEB-INF to make sure the app is 
portable ( if you rely on any tomcat-specific default, 
your app will work only on tomcat).

Server.xml sets server behavior. For example, the 
conversion between .jsp and java is a server property. 
The static interceptor is a server property. Everything 
that is not defined in the web.dtd belongs in server.xml,
and it's specific to tomcat. What is defined in web.dtd
and the spec belongs to WEB-INF/web.xml.

Web.xml is not read - it's just a template you can
use for your applications.
