Class BaseJkConfig

    java.lang.Object
      org.apache.jk.config.BaseJkConfig

All Implemented Interfaces:
  LifecycleListener

Direct Known Subclasses:
  ApacheConfig, IISConfig, NSConfig

public class BaseJkConfig
extends java.lang.Object
implements LifecycleListener

Base class for automatic jk based configurations based on the Tomcat server.xml settings and the war contexts initialized during startup.

This config interceptor is enabled by inserting a Config element in the <ContextManager> tag body inside the server.xml file like so:

     < ContextManager ... >
       ...
       <???Config options />
       ...
     < /ContextManager >

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.
- workersConfig - path to workers.properties file used by jk connector. If not set, defaults to "conf/jk/workers.properties".
- jkLog - path to log file to be used by jk connector.
- jkDebug - 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 may also need to modify the web server to point it's home directory to Tomcat's root context directory. Otherwise some content, such as the root index.html, may be served by the web server before the connector gets a chance to claim the request and pass it to Tomcat. The default is true.

  Throws:
    `java.io.IOException`

### getHost

    protected Host getHost(Container child)

  Get the host associated with this Container (if any).

### setAppend

    public void setAppend(boolean apnd)

  Append to config file. Set to `true` if the config information should be appended.

### setForwardAll

    public void setForwardAll(boolean b)

  If false, we'll try to generate a config that will let apache serve static files. The default is true, forward all requests in a context to tomcat.

### setNoRoot

    public void setNoRoot(boolean b)

  Special option - do not generate mappings for the ROOT context. The default is true, and will not generate the mappings, not redirecting all pages to tomcat (since /* matches everything). This means that the web server's root remains intact but isn't completely servlet/JSP enabled. If the ROOT webapp can be configured with the web server serving static files, there's no problem setting this option to false. If not, then setting it true means the web server will be out of picture for all requests.

### setConfigHome

    public void setConfigHome(java.lang.String dir)

  set a path to the parent directory of the conf folder. That is, the parent directory within which path setters would be resolved against, if relative. For example if ConfigHome is set to "/home/tomcat" and regConfig is set to "conf/mod_jk.conf" then the resulting path used would be: "/home/tomcat/conf/mod_jk.conf".

  However, if the path is set to an absolute path, this attribute is ignored.

  If not set, execute() will set this to TOMCAT_HOME.

### setWorkersConfig

    public void setWorkersConfig(java.lang.String path)

  set a path to the workers.properties file.

### setJkLog

    public void setJkLog(java.lang.String path)

  set the path to the log file

### setJkDebug

    public void setJkDebug(java.lang.String level)

  set the Ajp protocal

### setLegacy

    public void setLegacy(boolean legacy)

### initProperties

                                          java.io.PrintWriter pw)

  Add an extension mapping. Override with method to generate web server specific configuration
