Eclipse 在jboss服务器中部署war文件时出现NoClassDefFoundError/classnotfound异常？

在本例中，使用query从MySql获取数据，并将值设置为

SubjectScoreWithSubjectName

，并存储在数组列表中。但是这个例子在本地主机中的tomcat服务器的帮助下，在EclipseJuno中运行

完成此操作后，我想将其上传到在线JBOSS服务器，但它显示以下错误。？

**This is my java class (setter / getter method class)...

        my com.table.values.SubjectScoreWithSubjectName this class available in Project -> java resources -> src ->com.table.values.SubjectScoreWithSubjectName**



        package com.table.values;

**so if i have doing anything wrong then tell me .
thanks in advance.**

应用程序无法访问SubjectName.class

com/table/values/SubjectScore类

尝试将其包含在
WEB-INF\lib
文件夹中，或将其包含在服务器的
CLASSPATH

更新

有关JavaEE应用程序的基本结构，请参见

通常，您的库（JAR）应该位于
web inf/lib
中，您的类应该位于
web inf/classes
文件夹中

如果
com/table/values/SubjectScoreWithSubjectName
是一个单独的类，它应该进入classes文件夹，但是如果它在应用程序中导入的库中，它应该进入lib文件夹。
意味着我可以将我的all.class文件包含到WEB-INF\lib文件夹中。你的代码编译了吗？给我们一些代码片段，其中异常来自此代码，在localhost中很好，但每当我尝试部署到服务器时（联机）然后在上面显示错误根本原因java.lang.NoClassDefFoundError:com/table/values/SubjectScoreWithSubjectName类
SubjectScoreWithSubjectName
是从jar文件导入的还是自定义类？如果是您自己的类，请告诉我们如何使用它Yes SubjectScoreWithSubjectName是定制类（setter-getter方法类），在这个类中，我可以在（rs.next（））{SubjectScoreWithSubjectName score=new SubjectScoreWithSubjectName（）；score.setSUBJECT_ID（rs.getInt（“SUBJECT_ID”）；score.setSUBJECT_NAME（rs.getString）时设置值(“受试者姓名”）；分数。设置用户ID（rs.getInt（“用户ID”）；分数。设置累积分数（rs.getInt（“累积分数”）；用户受试者分数。添加（分数）；}
