Explanation/Reference:
The J2EE geocoder processes geocoding requests and generates responses. To enable this geocoding service, a geocoder.ear.zip file must be deployed using Oracle WebLogic Server.
Note: To deploy and configure the geocoding service, follow these steps.
Deploy the geocoder using Oracle WebLogic Server:
1. Unzip the geocoder.ear.zip file found in your $ORACLE_HOME/md/jlib directory into a suitable directory.
Your resulting directory structure should be: $geocoder.ear/web.war/....
Log on to the WebLogic Server console (for example, http://<hostname>:7001/console); and from Deployments install the geocoder.ear file, accepting the Name geocoder for the deployment and choosing the Location option Make the deployment accessible from the following location.
