java - Eclipse Tomcat java.lang.NoClassDefFoundError 日志工厂

Question

过去几天我一直在为这个错误而苦苦挣扎 java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory 以下是控制台输出。

我使用的是最新版本的 Tomcat 和 Eclipse。编辑 - 我尝试卸载 WAMP 并安装最新版本的 MYSQL 社区服务器无济于事；我仍然遇到同样的错误。

注意 - 我已经咨询过具有相同问题的主题，但建议的解决方案均不适合我。例如:java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

我尝试通过Eclipse中的服务器类路径配置将tomcat-juli.jar作为外部jar添加，更新系统环境变量类路径，将tomcat-juli.jar文件复制到JRE的lib文件夹中，并打开文件并确认 LogFactory 类确实存在。

编辑 - 此外，我能够运行 Tomcat 服务器并通过运行 startup.bat 在浏览器中查看默认页面。非常感谢任何帮助。

Answer 1

• 确保你的 tomcat 启动配置中有正确的 juli jar类路径。

• 另外，您的 DBCP jar 位于何处？尝试将 juli jar 放入同一个地点

我拥有的 JDK 1.8 在“jre\lib\ext”中有以下 JAR。将所有其他 jar 移动到指定认可的 tomcat。

access-bridge-64.jar
cldrdata.jar
dnsns.jar
jaccess.jar
jfxrt.jar
localedata.jar
meta-index
nashorn.jar
sunec.jar
sunjce_provider.jar
sunmscapi.jar
sunpkcs11.jar
zipfs.jar
