设置： Eclipse Juno R，Tomcat 7.0.8，tomcat 通过 eclipse 插件运行。来自 eclipse 的 Tomcat 启动配置有 VM 参数 -Djava.util.logging.config.file="C:\WS\Serverlogs\tomcat7\conf\logging .properties”（参考：在哪里可以查看 Eclipse 中的 Tomcat 日志文件？）出现以下错误。

Can't load log handler "1catalina.org.apache.juli.FileHandler"

“1catalina.org.apache.juli.FileHandler”、“2localhost.org.apache.juli.FileHandler”等也有类似的错误。我知道这些类来自 /bin 的 tomcat-juli.jar。我将此 jar 添加到服务器类路径中（Eclipse -> 服务器 -> 打开 -> 打开启动配置 -> 类路径 -> 用户条目），但得到了同样的错误。logging.properties 的内容是：

handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = C:\WS\Serverlogs\tomcat7/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.

2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = C:\WS\Serverlogs\tomcat7/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.

3manager.org.apache.juli.FileHandler.level = FINE
3manager.org.apache.juli.FileHandler.directory = C:\WS\Serverlogs\tomcat7/logs
3manager.org.apache.juli.FileHandler.prefix = manager.

4host-manager.org.apache.juli.FileHandler.level = FINE
4host-manager.org.apache.juli.FileHandler.directory = C:\WS\Serverlogs\tomcat7/logs
4host-manager.org.apache.juli.FileHandler.prefix = host-manager.

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = 3manager.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].handlers = 4host-manager.org.apache.juli.FileHandler

非常感谢任何输入/指导。找到了这些 How to configure Tomcat JULI logging to roll log files？ Local Tomcat Environment Not Starting ，但我的问题似乎有所不同。

Edit1 将“-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager”添加到服务器的 VM 参数并在 logging.properties 中将“\”更改为“/”就可以了。感谢 Robin 提供指向 Tomcat Logging FAQ 的指针

谢谢你，VJ

确保设置了以下系统属性，

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

正如在tomcat 用户邮件列表中看到的那样。

我在使用YAJSW而不是使用 tomcat 启动脚本启动 tomcat 时遇到了同样的问题。

您可以查看此特定问题的常见问题解答： http ://wiki.apache.org/tomcat/FAQ/Logging

或者您可以使用另一个 logging.properties，例如这个：

log4j.rootLogger=DEBUG, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout

# Print the date in ISO 8601 format
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

# Print only messages of level WARN or above in the package com.foo.
log4j.logger.com.foo=WARN
