java.lang.NoClassDefFoundError::Class 存在于 Tomcat 中的给定路径

转载作者：行者123 更新时间：2023-11-30 11:36:27

<分区>

我目前在运行 Jasper 报告应用程序时遇到问题。

调用我面临的报告生成请求后 java.lang.NoClassDefFoundError

对于应用程序类，例如com.abcd.framework.web.servicelocator.ServiceLocator

我验证了该类存在于 tomcat/WEB-INF/classes 文件夹下的适当路径中。

我还启用了 Tomcat 类加载器日志

JAVA_OPTS = -XX:+TraceClassLoading -XX:+TraceClassUnloading

相关日志:[从文件加载 com.abcd.framework.web.servicelocator.ServiceLocator:/C:/3.0/tomcat-6.0-Jasper/webapps/jasperserver-pro/WEB-INF/classes/com/abcd/framework/web/servicelocator/ServiceLocator.class]

我无法弄清楚为什么，尽管类已成功加载，但出现错误。

感谢您的帮助

谢谢
