Class ServletContextBeanFinder

java.lang.Object

org.togglz.servlet.spi.ServletContextBeanFinder

All Implemented Interfaces:

BeanFinder

public class ServletContextBeanFinder
extends Object
implements BeanFinder

This implementation of BeanFinder allows to register implementations of a given interface by setting a servlet context parameter. See the following configuration for an example how to register the implementation of TogglzConfig so that this class is able to find it.

   <context-param>
     <param-name>org.togglz.core.config.TogglzConfig</param-name>
     <param-value>com.example.myapp.TogglzConfigImpl</param-value>
   </context-param>
