Interface Plugin

public interface Plugin

The interface for Tagger Cat Plug-ins. Implement this interface to create your own plug-in classes. Plug-ins are classes to be loaded at application initialization.

Steps for installing a Plug-in:

1. Create a class that implements this interface.
2. Register the plug-in within the servlet section of the application deployment descriptor. Use a name prefix of "plug-in." in the <param-name> element.

   <servlet id="orderProcess">
         .....
           <init-param>
              <param-name>plug-in.MyPlugin</param-name>
              <param-value>sdi.util.MyPlugin</param-value>
           </init-param>
         .....
         </servlet>

3. Make your implementation class available to your applciation's class path as you would with any other class.

When your application is started, an instance of your plug-in class will be created, and its init() method will be called.
