Your component can implement: - ThreadSafe - Runnable - Startable - Stoppable - Configurable - Parameterizable - ...
Read "Developing with Avalon" on the jakarta.apache.org/Avalon for more info. See also comments in these interfaces. Then, you will have methods: - run() - start() - stop() - configure() - parameterize() Your component should be declared in the cocoon.xconf. Declaration could look like: <component role="com.mycompany.myproject.MyComponent" class="com.mycompany.myproject.MyComponentImpl"> <!-- for parameterizable: --> <parameter name="param" value="value"/> </component> PS If you need logger, it is good idea to extend from AbstractLoggable.
