| <p> |
| The Avalon Component service loads external modules which implement the |
| <a href="http://excalibur.apache.org/">Avalon</a> lifecycle interfaces. |
| </p> |
| <p> |
| The only supported component is <a href="http://db.apache.org/torque/">Torque</a>. |
| <a href="http://turbine.apache.org/fulcrum/">Fulcrum</a> components are |
| supported via the <a href="yaafi-component-service.html">Yaafi Component Service</a>. |

| <p> |
| In /WEB-INF/conf you should provide componentConfiguration.xml: |
| </p> |
| <source><![CDATA[ |
| <componentConfig> |
| <torque> |
| <configfile>/WEB-INF/conf/torque.properties</configfile> |
| </torque> |

| <p> |
| No changes to torque.properties are required. |

| If all goes well you should see the following in your log file when |

| <section name="Usage"> |
| |
| <p> |
| If you plan to use the decoupled Torque in your application, you should |
| leave the Avalon Component Service configured at all times. It is started at |
| early startup time. Once it has initialized all the components, there |
| are no application specific methods or services available. |
