16.9.3. Configure NSAPI as a Basic HTTP Connector

Overview

This task configures the NSAPI connector to redirect client requests to JBoss EAP 6 servers with no load-balancing or fail-over. The redirection is done on a per-deployment (and hence per-URL) basis. For a load-balancing configuration, refer to Section 16.9.4, “Configure NSAPI as a Load-balancing Cluster” instead.

Prerequisites

Procedure 16.14. Setup the Basic HTTP Connector

  1. Define the URL paths to redirect to the JBoss EAP 6 servers.

    Note

    In IPLANET_CONFIG/obj.conf, spaces are not allowed at the beginning of a line, except when the line is a continuation of the previous line.
    Edit the IPLANET_CONFIG/obj.conf file. Locate the section which starts with <Object name="default">, and add each URL pattern to match, in the format shown by the example file below. The string jknsapi refers to the HTTP connector which will be defined in the next step. The example shows the use of wildcards for pattern matching.
    <Object name="default">
    [...]
    NameTrans fn="assign-name" from="/status" name="jknsapi"
    NameTrans fn="assign-name" from="/images(|/*)" name="jknsapi"
    NameTrans fn="assign-name" from="/css(|/*)" name="jknsapi"
    NameTrans fn="assign-name" from="/nc(|/*)" name="jknsapi"
    NameTrans fn="assign-name" from="/jmx-console(|/*)" name="jknsapi"
    </Object>
    
    
  2. Define the worker which serves each path.

    Continue editing the IPLANET_CONFIG/obj.conf file. Add the following directly after the closing tag of the section you have just finished editing: </Object>.
    <Object name="jknsapi">
    ObjectType fn=force-type type=text/plain
    Service fn="jk_service" worker="worker01" path="/status"
    Service fn="jk_service" worker="worker02" path="/nc(/*)"
    Service fn="jk_service" worker="worker01"
    </Object>
    
    
    The example above redirects requests to the URL path /status to the worker called worker01, and all URL paths beneath /nc/ to the worker called worker02. The third line indicates that all URLs assigned to the jknsapi object which are not matched by the previous lines are served to worker01.
    Save and exit the file.
  3. Define the workers and their attributes.

    Create a file called workers.properties in the IPLANET_CONFIG/connectors/ directory. Paste the following contents into the file, and modify them to suit your environment.
    # An entry that lists all the workers defined
    worker.list=worker01, worker02
    
    # Entries that define the host and port associated with these workers
    worker.worker01.host=127.0.0.1
    worker.worker01.port=8009
    worker.worker01.type=ajp13
    
    worker.worker02.host=127.0.0.100
    worker.worker02.port=8009
    worker.worker02.type=ajp13
    
    The workers.properties file uses the same syntax as Apache mod_jk. For information about which options are available, refer to Section 16.6.4, “Configuration Reference for Apache Mod_jk Workers”.
    Save and exit the file.
  4. Restart the iPlanet Web Server.

    Issue the following command to restart the iPlanet Web Server.
    IPLANET_CONFIG/../bin/stopserv
    IPLANET_CONFIG/../bin/startserv
    
Result

iPlanet Web Server now sends client requests to the URLs you have configured to deployments on JBoss EAP 6.
