}

说明：把用户名称和用户密码提交到/tomcat/webapps/canyin/jsp/loginjudge.jsp
/tomcat/webapps/canyin/WEB-INF/classes/canyin/checkSessionBean.class （代码是相应的java 文件）
package canyin;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
public class checkSessionBean {
private boolean bolCheckPass=false;
private HttpServletRequest request = null;
public boolean checkSessionBean(HttpServletRequest request,String strSessionName,String strCheckValue){
public boolean checkSessionBean(HttpServletRequest request){
HttpSession session = request.getSession(false); |
