errbean.java

学习struts标签库,里面随带了相关的演示程序代码,非常好学.

package org.apache.struts.webapp.exercise;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.ActionMessages;

public class ErrBean extends ActionForm{
	
	private boolean checkbox1;

	public boolean isCheckbox1() {
		return checkbox1;
	}

	public void setCheckbox1(boolean checkbox1) {
		this.checkbox1 = checkbox1;
	}
	
	public void reset(ActionMapping mapping, HttpServletRequest request){
		this.setCheckbox1(false);
	}
	
	public ActionErrors validate(ActionMapping mapping, HttpServletRequest request){
		
		ActionErrors errors = new ActionErrors();
		if (checkbox1){
			errors.add(ActionMessages.GLOBAL_MESSAGE,new ActionError("html.errors.error1"));
			errors.add("checkbox1",new ActionError("html.errors.error2"));
		}
		return errors;
	}
