All Implemented Interfaces:

LifecycleListener

public class NSConfig
extends BaseJkConfig

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

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

 < ContextManager ... >
   ...
   <NSConfig options />
   ...
 < /ContextManager >
    

• 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.
• objConfig - path to use for writing Netscape obj.conf file. If not set, defaults to "conf/auto/obj.conf".
• objectName - Name of the Object to execute the requests. Defaults to "servlet".
• workersConfig - path to workers.properties file used by nsapi_redirect. If not set, defaults to "conf/jk/workers.properties".
• nsapiJk - path to Netscape mod_jk plugin file. If not set, defaults to "bin/nsapi_redirect.dll" on windows, "bin/nsapi_rd.nlm" on netware, and "bin/nsapi_redirector.so" everywhere else.
• jkLog - path to log file to be used by nsapi_redirect.
• 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 Netscape 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 Netscape. Review the uriworkermap file to see what configuration is actually being set in Netscape.
• 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 Home Directory setting in Netscape to point to Tomcat's root context directory. Otherwise some content, such as the root index.html, will be served by Netscape before nsapi_redirect gets a chance to claim the request and pass it to Tomcat. The default is true.

NSConfig

public NSConfig()

setObjConfig

public void setObjConfig(java.lang.String path)

set the path to the output file for the auto-generated isapi_redirect registry file. If this path is relative then getRegConfig() will resolve it absolutely against the getConfigHome() path.

Parameters:

path - String path to a file

setNsapiJk

public void setNsapiJk(java.lang.String path)

set the path to the nsapi plugin module

Parameters:

path - String path to a file

setObjectName

public void setObjectName(java.lang.String name)

Set the name for the Object that implements the jk_service call.

Parameters:

name - Name of the obj.conf Object

initProperties

protected void initProperties()

Initialize defaults for properties that are not set explicitely

Overrides:

initProperties in class BaseJkConfig

Description copied from class: BaseJkConfig

Get the output Writer. Override with method to generate web server specific configuration.

Overrides:

getWriter in class BaseJkConfig

Throws:

java.io.IOException

generateJkHead

protected boolean generateJkHead(java.io.PrintWriter mod_jk)

Description copied from class: BaseJkConfig

Generate general options

Overrides:
