Added: jk/java/org/apache/ajp/tomcat4/config ApacheConfig.java
BaseJkConfig.java IISConfig.java NSConfig.java
Log:
Initial version of AutoConfig for Ajp13 and Tomcat 4.0.1.
The default forwardAll works as expected. However, there are still some issues with
the "static files to Apache" mode. These are mostly having to do with getting
information out of Catalina that it doesn't want to give up without a fight.

/* The idea is to keep all configuration in server.xml and
the normal apache config files. We don't want people to
touch apache ( or IIS, NES ) config files unless they
want to and know what they're doing ( better than we do :-).
One nice feature ( if someone sends it ) would be to
also edit httpd.conf to add the include.
We'll generate a number of configuration files - this one
is trying to generate a native apache config file.
Some web.xml mappings do not "map" to server configuration - in
this case we need to fallback to forward all requests to tomcat.
Ajp14 will add to that the posibility to have tomcat and
apache on different machines, and many other improvements -
but this should also work for Ajp12, Ajp13 and Jni.

/**
Generates automatic apache mod_jk configurations based on
the Tomcat server.xml settings and the war contexts
initialized during startup.
<p>
This config interceptor is enabled by inserting an ApacheConfig
element in the <b><ContextManager></b> tag body inside
the server.xml file like so:
<pre>
* < ContextManager ... >
* ...
* <<b>ApacheConfig</b> <i>options</i> />
* ...
* < /ContextManager >
</pre>
where <i>options</i> can include any of the following attributes:
<ul>
<li><b>configHome</b> - default parent directory for the following paths.
If not set, this defaults to TOMCAT_HOME. Ignored
whenever any of the following paths is absolute.
</li>
<li><b>jkConfig</b> - path to use for writing Apache mod_jk conf file. If
not set, defaults to
"conf/auto/mod_jk.conf".</li>
<li><b>workersConfig</b> - path to workers.properties file used by
mod_jk. If not set, defaults to
"conf/jk/workers.properties".</li>
<li><b>modJk</b> - path to Apache mod_jk plugin file. If not set,
defaults to "modules/mod_jk.dll" on windows,
"modules/mod_jk.nlm" on netware, and
"libexec/mod_jk.so" everywhere else.</li>
<li><b>jkLog</b> - path to log file to be used by mod_jk.</li>
<li><b>jkDebug</b> - JK Loglevel setting. May be debug, info, error, or emerg.
If not set, defaults to emerg.</li>
<li><b>jkWorker</b> The desired worker. Must be set to one of the workers
defined in the workers.properties file. "ajp12", "ajp13"
or "inprocess" are the workers found in the default
workers.properties file. If not specified, defaults
to "ajp13" if an Ajp13Interceptor is in use, otherwise
it defaults to "ajp12".</li>
<li><b>forwardAll</b> - If true, forward all requests to Tomcat. This helps
insure that all the behavior configured in the web.xml
file functions correctly. If false, let Apache serve
static resources. The default is true.
Warning: When false, some configuration in
the web.xml may not be duplicated in Apache.
Review the mod_jk conf file to see what
configuration is actually being set in Apache.</li>
<li><b>noRoot</b> - If true, the root context is not mapped to
Tomcat. If false and forwardAll is true, all requests
to the root context are mapped to Tomcat. If false and
forwardAll is false, only JSP and servlets requests to
the root context are mapped to Tomcat. When false,
to correctly serve Tomcat's root context you must also
modify the DocumentRoot setting in Apache's httpd.conf
file to point to Tomcat's root context directory.
Otherwise some content, such as Apache's index.html,
will be served by Apache before mod_jk gets a chance
to claim the request and pass it to Tomcat.
The default is true.</li>

/**
Generates automatic IIS isapi_redirect configurations based on
the Tomcat server.xml settings and the war contexts
initialized during startup.
<p>
This config interceptor is enabled by inserting an IISConfig
element in the <b><ContextManager></b> tag body inside
the server.xml file like so:
<pre>
* < ContextManager ... >
* ...
* <<b>IISConfig</b> <i>options</i> />
* ...
* < /ContextManager >
</pre>
where <i>options</i> can include any of the following attributes:
<ul>
<li><b>configHome</b> - default parent directory for the following paths.
If not set, this defaults to TOMCAT_HOME. Ignored
whenever any of the following paths is absolute.
</li>
<li><b>regConfig</b> - path to use for writing IIS isapi_redirect registry
file. If not set, defaults to
"conf/auto/iis_redirect.reg".</li>
<li><b>workersConfig</b> - path to workers.properties file used by
isapi_redirect. If not set, defaults to
"conf/jk/workers.properties".</li>
<li><b>uriConfig</b> - path to use for writing IIS isapi_redirect uriworkermap
file. If not set, defaults to
"conf/auto/uriworkermap.properties".</li>
<li><b>jkLog</b> - path to log file to be used by isapi_redirect.</li>
<li><b>jkDebug</b> - Loglevel setting. May be debug, info, error, or emerg.
If not set, defaults to emerg.</li>
<li><b>jkWorker</b> The desired worker. Must be set to one of the workers
defined in the workers.properties file. "ajp12", "ajp13"
or "inprocess" are the workers found in the default
workers.properties file. If not specified, defaults
to "ajp13" if an Ajp13Interceptor is in use, otherwise
it defaults to "ajp12".</li>
<li><b>forwardAll</b> - If true, forward all requests to Tomcat. This helps
insure that all the behavior configured in the web.xml
file functions correctly. If false, let IIS serve
static resources assuming it has been configured
to do so. The default is true.
Warning: When false, some configuration in
the web.xml may not be duplicated in IIS.
Review the uriworkermap file to see what
configuration is actually being set in IIS.</li>
<li><b>noRoot</b> - If true, the root context is not mapped to
Tomcat. If false and forwardAll is true, all requests
to the root context are mapped to Tomcat. If false and
forwardAll is false, only JSP and servlets requests to
the root context are mapped to Tomcat. When false,
to correctly serve Tomcat's root context you must also
modify the Home Directory setting in IIS
to point to Tomcat's root context directory.
Otherwise some content, such as the root index.html,
will be served by IIS before isapi_redirect gets a chance
to claim the request and pass it to Tomcat.
The default is true.</li>
