我在J2EE应用程序中使用枚举时遇到问题.我在无状态服务bean中的switch case中使用enum.
在运行期间,我在switch语句中看到以下异常：
Caused by: java.lang.NoClassDefFoundError: com/comp/service/TestServiceImpl$1
这个问题已经在SO的一个主题上进行了广泛的讨论.但我没有看到任何解决方案来解决这个问题.
在我的情况下,我使用JBOSS EAP6.1服务器. JDK版本是1.7.代码是在Eclipse IDE中使用Maven构建的.应用程序部署为EAR存档.如何在我的EAR存档中的类路径中添加这个额外生成的类文件？有没有其他方法可以解决这个问题？
2014年6月29日更新：
我试图从命令行构建应用程序.然后生成这个额外的类文件.而且我能够成功地执行应用程序.这似乎是日食的错误.知道怎么解决吗？
