» 2. Derivation of the Action class for the Struts adapter

Our table has to display information on the system users. Therefore, the action class which takes care of the loading and filling of the ListControl must have the nomenclature "UserBrowseAction". The action class is then derived from the class FWAction, which the Struts action class encapsulates 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 UserBrowseAction 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 ListControl with the DisplayData
    }
}
