简单的struts例子 使用action的时候报错,大虾急救阿!
我定义了 1个jsp页面 1个Action 1个ActionForm
//public class LoginForm extends ActionForm
//public class LoginAction extends Action
//login.jsp
//struts-config.xml
<form-beans>
<form-bean name="LoginForm2" path="StrutsTest.FormBean.LoginForm">
</form-bean>
</form-beans>
<action-mappings>
<action path="/Login"
type="StrutsTest.Action.LoginAction"
name="LoginForm2"
scope="request"
validate="false"
input="/strutsTest/Login.jsp">
<forward name="view" path="/strutsTest/login.jsp"/>
</action>
//jsp页面信息
<html:form action="/Login.do" >
UserName: <html:text property="user2" />
Password: <html:password property="pass2" />
<html:submit value="commit"/>
</html:form>
结果访问该页面的时候就报错了：
javax.servlet.jsp.JspException: Exception creating bean of class null: {1}
//看别人的也有过类似的错误，但是 class 也不是null啊？
兄弟们，小弟初学struts，摸索很久了，大虾们指点阿!感激不敬
就是下面的
[ServletContext(id=37125271,name=MyWebApp,context-path=/MyWebApp)] Root cause of
ServletException.

你用以上标签写的,哪么你的StrutsTest.FormBean.LoginForm.java这个类中,有没有对应的
user2和pass2的相关get和set方法啊?这里必须对应上
