Question

我正在使用Apache Struts开发一个Web应用程序，以部署在JBoss Server上。使用eclipse进行开发。

我已将web.xml配置为将所有* .do请求转发给ActionServlet。

JSP页面（abc.jsp）的表单为action =“newgoal.do”。

struts-config.xml文件包含以下条目：

 <action path="/newgoal" type="com.misys.trng.AddingNewGoalAction">
 </action>

我已经确认班级的路径是正确的。

我的网络应用程序中的所有其他.do转发工作正常。当我从abc.jsp提交表单时，我得到以下异常：

我无法理解错误是什么。当其他所有其他工作正常时，为什么我的应用程序无法加载1个特定类。请帮忙。

Answer 1

该类必须存在于WEB-INF/classes下或位于WEB-INF/lib下的.jar文件中。确保它确实如此。

Answer 2

也许某些事情在你的行动中是静止的？我有同样的问题。使用不存在的属性中的值初始化一个静态变量，然后不初始化操作。

使用struts的Web应用程序中的ClassNotFoundException
