Question

过去几天我一直在努力解决这个错误java.lang.NoClassDefFoundError：org / apache / juli / logging / LogFactory下面是控制台输出。

我正在使用最新版本的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 - 我已就同一问题咨询了主题，但没有一个解决方案对我有用。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添加为外部jar，更新系统环境变量Classpath，将tomcat-juli.jar文件复制到JRE的lib文件夹中，然后打开文件并确认LogFactory类确实存在。

编辑 - 此外，我可以通过运行startup.bat来运行Tomcat服务器并在浏览器中查看默认页面。非常感谢任何帮助。

Answer 1

确保您的tomcat启动配置中包含正确的juli jar 类路径。

Tomcat launch configuration

您的DBCP广告位于哪里？尝试将juli jar放入其中位置

JDK 1.8我在“jre \ lib \ ext”中跟随JAR。将所有其他jar移动到指定的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

Answer 2

这绝对可以帮助您找到原因。将以下内容附加到tomcat jvm启动参数

-verbose:class

如果您正在运行独立的Tomcat（通过运行startup.bat），您可以在catalina.bat

中添加以下行

set JAVA_OPTS=%JAVA_OPTS% -verbose:class

这样做是在控制台/日志上打印 - 从java引导程序开始加载它的类和jar文件位置，直到服务器引导程序和应用程序类。简而言之，成功运行应用程序所需的所有类。这些信息很冗长，但在确定挑选类的确切jar或者即使没有挑选jar时也非常有用。如果将信息输出到文件然后使用文本编辑器进行文本搜索，将会非常有用。

在我的Tomcat安装上，它显示了这样的信息

[Loaded java.lang.Void from C:\Program Files\Java\jdk1.7.0_51\jre\lib\rt.jar]
[Loaded org.apache.juli.logging.LogFactory from file:/D:/apache-tomcat-7.0.50/bin/tomcat-juli.jar]
[Loaded org.apache.juli.logging.Log from file:/D:/apache-tomcat-7.0.50/bin/tomcat-juli.jar]
[Loaded org.apache.juli.logging.DirectJDKLog from file:/D:/apache-tomcat-7.0.50/bin/tomcat-juli.jar]
[Loaded java.util.logging.Logger from C:\Program Files\Java\jdk1.7.0_51\jre\lib\rt.jar]
[Loaded java.util.logging.Handler from C:\Program Files\Java\jdk1.7.0_51\jre\lib\rt.jar]

您可以看到org.apache.juli.logging.LogFactory正在加载file:/D:/apache-tomcat-7.0.50/bin/tomcat-juli.jar

Answer 3

虽然之前发布的答案解决了问题，但这是一个肮脏的解决方案。

按照以下链接中的说明正确配置DBCP jar。同时将任何其他罐子移出到$ CATALINA_HOME /背书目录

JNDI Datasource HOW-TO

The Tomcat JDBC Connection Pool

Answer 4

这是清单： -

tomcat-juli.jar的相同副本出现在JRE \ lib，TOMCAT \ lib和eclipse的启动配置中，以确保使用的包含LogFactory。
您正在使用内置服务器配置工具中的Eclipse而不是插件。
可能是您正在使用的tomcat版本中的bug。

Eclipse Tomcat java.lang.NoClassDefFoundError LogFactory
