tomcat in linux:java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

Question

when I startup tomcat in linux,I met a problem. Using CLASSPATH:/data/apache-tomcat-7.0.47/bin/bootstrap.jar:/data/apache-tomcat-7.0.47/bin/tomcat-juli.jar

`Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:60)
Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

I know that class can't be found,but the jar has been in the classpath. So why? I will be appreciated if you can answer my question.thank you.

Solution

In my case the error was in skiped quotes "" after --Classpath. The correct run script is

%CATALINA_HOME%\bin\tomcat7 //IS//Tomcat7 --DisplayName="Apache Tomcat 7" --Install="C:\tomcat-7.0\bin\tomcat7.exe" --Jvm=auto --StartMode=jvm --StopMode=jvm --Classpath="%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar;%CATALINA_HOME%\bin\tomcat-juli.jar" --StartClass=org.apache.catalina.startup.Bootstrap --StartParams=start --StopClass=org.apache.catalina.startup.Bootstrap --StopParams=stop
