In our tree, we want to display product groups and products. Therefore, the action class which takes care of the loading and filling of the TreeControl must have the nomenclature "ProductTreeBrowseAction".

The action class is then derived from the class FWAction, which encapsulates the Struts-action class and extends with functionalities of the presentation framework. Instead of the execute()-method, the doExecute()-method is called. On calling, it gets the ActionContext, through which the access to additional objects such as the Request- Session- and Response-object is capsulated.

import java.io.IOException;
import javax.servlet.ServletException;

import com.cc.framework.adapter.struts.FWAction
import com.cc.framework.adapter.struts.ActionContext

public class ProductTreeBrowseAction extends FWAction {

    /**
     * @see com.cc.framework.adapter.struts.FWAction#doExecute(ActionContext)
     */
    public void doExecute(ActionContext ctx)
        throws IOException, ServletException {
        // In the next chapter, we will instantiate
        // our TreeControls with the DisplayData
    }
}
