All Implemented Interfaces:
  LifecycleListener

public class ApacheConfig
extends BaseJkConfig

Generates automatic apache mod_jk configurations based on the Tomcat server.xml settings and the war contexts initialized during startup.

This config interceptor is enabled by inserting an ApacheConfig `Listener` in the server.xml file like so:

     < Server ... >
       ...
       org.apache.ajp.tomcat4.config.ApacheConfig
           options />
       ...
     < /Server >

where options can include any of the following attributes:

- configHome - default parent directory for the following paths. If not set, this defaults to TOMCAT_HOME. Ignored whenever any of the following paths is absolute.
- jkConfig - path to use for writing Apache mod_jk conf file. If not set, defaults to "conf/auto/mod_jk.conf".
- workersConfig - path to workers.properties file used by mod_jk. If not set, defaults to "conf/jk/workers.properties".
- modJk - 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.
- jkLog - path to log file to be used by mod_jk.
- jkDebug - JK Loglevel setting. May be debug, info, error, or emerg. If not set, defaults to emerg.
- jkWorker 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".
- forwardAll - 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.
- noRoot - 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.

### MOD_JK

    public static final java.lang.String MOD_JK

Constructor Detail

### ApacheConfig

    public ApacheConfig()

Method Detail

### setJkConfig

    public void setJkConfig(java.lang.String path)

  set the path to the output file for the auto-generated mod_jk configuration file. If this path is relative then it will be resolved absolutely against the getConfigHome() path.

### setExtractSSL

    public void setExtractSSL(boolean sslMode)

  By default mod_jk is configured to collect SSL information from the apache environment and send it to the Tomcat workers.

The following JK related SSL configureation can be used to customize mod_jk's SSL behaviour. Should mod_jk send SSL information to Tomact (default is On)
