I actually have gotten this to work, but I don't understand why I had to do
what I did to accomplish this.
To review... I wanted to insert a layer of abstraction between
org.apache.struts.action.Action and my web application's various
instantiations of Action.
IE:
MyAction subclasses DHSAction, which inturn subclasses Action.
Originally DHSAction.java looked like this:
package dhs.struts.action;
import org.apache.struts.action.Action ;
public class DHSAction extends Action { }
Now, it looks like this:
package dhs.struts.action;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action ;
import org.apache.struts.action.ActionForm ;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.util.MessageResources;
public class DHSAction extends Action {
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
return (mapping.findForward("success"));
}
}
I am not the sharpest Java tool in the shed, but I thought that public
classes and public methods would be visible to subclasses without having to
repeat the method signature.
I guess I don't understand all I know about this.
