Re: java.lang.NoClassDefFoundError: org/apache/catalina/loader/WebappClassLoader

Bad move. Each jar should only exist once. If it's in tomcat's common/lib, it can't exist in your webapp's WEB-INF/lib and vice-versa. I suspect this is more a spring question than a tomcat question as spring does some interesting things with the classloader. The class in question in particular seems to requre another jar named spring-tomcat-weaver.jar in tomcat's server/lib directory as well as a <Loader .../> element in your context.xml file.

I download the Tomcat 5.5.17 and I got the same exception.
I am not sure it is really the downloaded file is corrupt. The war I deploy is a spring application. At the beginning as I deploy it, I got exception like: java.lang.IllegalStateException: ContainerBase.addChild: start: LifecycleException: start: : java.lang.ClassNotFoundException: org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader 
...
Then I copy the spring.jar onto /tomcat_home/commond/lib and reploy my war again. Then I got the exception as mentioned earlier. ********************** Your download is most probably corrupted, redownload the file from server, and extract it to a fresh new folder. 
This kind of error can happen when one of the tomcat jar file is either

corrupted or just missing.

Hi all,
I just download and install the Tomcat 5.5.23. As I try to deploy 
my web application (a war file), I got exceptions as follow. Someone
knows why?
