19.9.4. Configure NSAPI as a Load-balancing Cluster
This task configures the NSAPI connector to redirect client requests to JBoss EAP 6 servers in a load-balancing configuration. To use NSAPI as a simple HTTP connector with no load-balancing, refer to Section 19.9.3, “Configure NSAPI as a Basic HTTP Connector” instead.
- You must complete Section 19.9.2, “Configure the NSAPI Connector on Oracle Solaris” before continuing with the current task.
Procedure 19.22. Configure the Connector for Load-Balancing
Define the URL paths to redirect to the JBoss EAP 6 servers.
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.conffile. 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
jknsapirefers 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" NameTrans fn="assign-name" from="/jkmanager/*" name="jknsapi" </Object>
Define the worker that serves each path.Continue editing the
IPLANET_CONFIG/obj.conffile. Directly after the closing tag for the section you modified in the previous step (
</Object>), add the following new section and modify it to your needs:
<Object name="jknsapi"> ObjectType fn=force-type type=text/plain Service fn="jk_service" worker="status" path="/jkmanager(/*)" Service fn="jk_service" worker="router" </Object>This
jksnapiobject defines the worker nodes used to serve each path that was mapped to the
name="jksnapi"mapping in the
defaultobject. Everything except for URLs matching
/jkmanager/*is redirected to the worker called
Define the workers and their attributes.Create a file called
. Paste the following contents into the file, and modify them to suit your environment.

Restart the iPlanet Web Server.Choose one of the following procedures, depending on whether you run iPlanet Web Server 6.1 or 7.0.
iPlanet Web Server 6.1
iPlanet Web Server 7.0
The iPlanet Web Server redirects the URL patterns you have configured to your JBoss EAP 6 servers in a load-balancing configuration.
