Retrieving the Component Type

As explained earlier, the first thing MapTag does is to retrieve the type of the component. It does this by using the getComponentType operation:

    public String getComponentType() {
        return ("DemoMap");

The value returned from getComponentType must match the value configured for the component with the component-type element of the application’s application configuration resource file. Registering a Custom Component explains how to configure a component.
