使用本指南在我的Debian服务器上安装最新的Jetty 9：http://techtraits.com/jetty9install/
在没有任何webapps的情况下启动时运行完美，但是在运行webapps时启动：
# service jetty start
Starting Jetty: .
FAILED T juuli 8 17:13:24 EEST 2014
所以我检查了logs / start.log：
StartLog Establishing /opt/jetty/logs/start.log on Tue Jul 08 17:13:16 EEST 2014
和logs / 2014_07_08.stderrout.log：
2014-07-08 17:13:17.584:INFO:oejs.Server:main: jetty-9.2.0.v20140526
2014-07-08 17:13:17.657:INFO:oejdp.ScanningAppProvider:main: Deployment monitor [file:/opt/jetty/webapps/] at interval 1
我尝试修改resources / log4j.properties：
log4j.rootLogger=DEBUG, FILE
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
log4j.appender.FILE.File=lll.out
我的服务器上没有lll.out.
我尝试将其作为：
运行java -jar start.jar --daemon -DDEBUG=true -Dorg.eclipse.jetty.LEVEL=DEBUG
我得到的只是：
WARNING: System properties and/or JVM args set. Consider using --dry-run or --exec
System Property [DEBUG] has been deprecated! (Use org.eclipse.jetty.LEVEL=DEBUG instead)

在其他情况下，使用不同webapp的相同设置对我有用。如果我能想出某种类型的错误信息就好了，但是我一直在苦苦挣扎，没有运气，现在已经有一段时间了。如果有人有建议我会非常感激。
