The default configuration uses the following URL's:

  * Portal: [http://localhost:8080/portal][4]
  * Base URL for rendering OpenSocial gadgets http://localhost:8080/gadgets

## Override portal configuration
First configure the portal to call a different URL for the OpenSocial engine:

  * Make a copy of [portal.properties][1]
  * Change the properties `portal.opensocial_engine.protocol`, `portal.opensocial_engine.root` and/or `portal.opensocial_engine.gadget_path`
  * Set a system property `portal.override.properties` that points to the location of the custom properties file.
    * File system: `portal.override.properties=/new/location/of/myportal.properties`
    * Classpath: `portal.override.properties=classpath:myportal.properties`

After a (re)start of Tomcat, the portal will now try to fetch gadget rendering data from your configured location.

## Override OpenSocial engine configuration

  * Make a copy of [container.js][2] (check if this version is still valid for your release)
  * Make a copy of [rave.shindig.properties][6]
  * Change the reference in `rave.shindig.properties` to `container.js`: `shindig.containers.default=/new/location/of/container.js`
  * Change the properties that point to localhost, port 8080 or http
  * Set a system property `rave-shindig.override.properties` that points to the location of the custom properties file.
    * File system: `rave-shindig.override.properties=/new/location/of/myrave-shindig.properties`
    * Classpath: `rave-shindig.override.properties=classpath:myrave-shindig.properties`

Note: Although `shindig.host`, `shindig.port` and `shindig.contextroot` can also be overridden by setting them as individual system properties, `container.js` contains hard coded values with `localhost`

## Setting the system properties
### Running Cargo
The Cargo Maven plugin is configured in `rave-portal/pom.xml`. Go to the element `systemProperties` and enable the elements
`portal.override.properties` and `rave-shindig.override.properties` (also modify its paths).

    <systemProperties>
        <net.sf.ehcache.skipUpdateCheck>true</net.sf.ehcache.skipUpdateCheck>
        <portal.override.properties>/path/to/custom.portal.properties</portal.override.properties>
        <rave-shindig.override.properties>/path/to/custom.shindig.properties</rave-shindig.override.properties>
    </systemProperties>

### Running a stand alone Tomcat server
A common location to set the system properties is in tomcat/bin/setenv.sh. Add a variable `RAVE_OPTS`

    RAVE_OPTS="-Dportal.override.properties=/path/to/custom.portal.properties
               -Drave-shindig.override.properties=/path/to/custom.rave.shindig.properties"

Then add it to the `CATALINA_OPTS` variable

    CATALINA_OPTS="${CATALINA_OPTS} ${RAVE_OPTS}"
