下面是LoginAction中的execute()方法中的内容:
LoginForm loginForm = (LoginForm) form;
//判断用户的登录信息是否正确
Login login = new Login();
boolean fal = false;
fal = login.exeLogin(loginForm.getLoginname(),loginForm.getLogpassword());
//exeLogin()这个方法我测试过没问题,能够正常判断
if(fal)
{
List admins = new ArrayList();
Admin admin = new Admin();
admins = admin.getAllInfo();
request.setAttribute("admins",admins);
return mapping.findForward("success");
}
return mapping.findForward("error");
下面是struts-config.xml文件<action-mappings>中的内容:
<action
attribute="LoginForm"
input="/form/login.jsp"
name="LoginForm"
path="/login"
scope="request"
type="com.yourcompany.struts.action.LoginAction" >
<forward name="success" path="/success.jsp" />
<forward name="error" path="/MyJsp.jsp" />
</action>
下面是错误信息:
在LoginAction的exeLogin方法中的if(fal)不成立时候能够正确的执行return mapping.findForward("error");
当if(fal)成立时执行跳转return mapping.findForward("success");会报如下异常:
javax.servlet.ServletException: Cannot create rewrite URL: java.net.MalformedURLException: You must specify exactly one of "forward", "href", "page" or "action"

这个是我的LoginAction的代码:



package com.yourcompany.struts.action;



import java.util.ArrayList;

import java.util.List;



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 admin.Admin;

import login.Login;

import com.yourcompany.struts.form.LoginForm;



public class LoginAction extends Action {

	public ActionForward execute(

		ActionMapping mapping,

		ActionForm form,

		HttpServletRequest request,

		HttpServletResponse response) {

		LoginForm loginForm = (LoginForm) form;

		//判断用户的登录信息是否正确

		Login login = new Login();

		boolean fal = false;

		fal = login.exeLogin(loginForm.getLoginname(),loginForm.getLogpassword());

		if(fal)

		{

			List admins = new ArrayList();

			Admin admin = new Admin();

			admins = admin.getAllInfo();

			request.setAttribute("admins",admins);

			return mapping.findForward("okokok");

		}

		return mapping.findForward("error");

	}

}

会不会跟你的struts版本有问题/

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://struts.apache.org/dtds/struts-config_1_2.dtd">

哦楼上说的这个原因是刚才有人叫我换个字符串试试所以我把 success换成okoko试了一下
但是也还是不可以刚才复制代码的时候没有改过来让你误会了

mapping.findForward("success");

确认这个success在struts-config.xml 里面有？

你的config文件没有看到这个阿！
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<form-beans >
<form-bean name="LoginForm" type="com.yourcompany.struts.form.LoginForm" />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<action
attribute="LoginForm"
input="/form/login.jsp"
name="LoginForm"
path="/login"
scope="request"

<forward name="okokok" path="/success.jsp" />
<forward name="error" path="/MyJsp.jsp" />
</action>
</action-mappings>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

这个异常会不会和JDBC驱动有关系?

修改成这样试下:



<action path="/login" scope="request" name="LoginForm" type="com.yourcompany.struts.action.LoginAction"   > 

            <forward   name="okokok"   path="/success.jsp"   /> 

            <forward   name="error"   path="/MyJsp.jsp"   /> 

        </action>

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<action

<forward name="okokok" path="/success.jsp" />
<forward name="error" path="/MyJsp.jsp" />
</action>
</action-mappings>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>
