问题
I am currently facing with a problem where I am running a Jasper report application.
After invoking a report generation request I am facing
java.lang.NoClassDefFoundError
for an application class e.g. com.abcd.framework.web.servicelocator.ServiceLocator
I verified that the class is present at the appropriate path under the tomcat/WEB-INF/classes folder.
I also enabled Tomcat classloader logs with
JAVA_OPTS = -XX:+TraceClassLoading -XX:+TraceClassUnloading
the relevant log:
[Loaded com.abcd.framework.web.servicelocator.ServiceLocator from file:/C:/3.0/tomcat-6.0-Jasper/webapps/jasperserver-pro/WEB-INF/classes/com/abcd/framework/web/servicelocator/ServiceLocator.class]
I am not able to figure out why, despite the class is successfully loaded, am getting error.
Appreciate your help
Thanks

回答1:
NoClassDefFound indicates, that everything was okay at compile time, but not at runtime. Maybe some of your .jars are missing on your tomcat. You have to add them to tomcat classpath or copy them to the JRE your tomcat is running on.
here Why am I getting a NoClassDefFoundError in Java? you may find some more information/explanation.
and here Jars not copied to Tomcat's lib folder is a thread about setting up eclipse to deploy dependencies automatically.
回答2:
Some clarifications:
NoClassDefFoundError!=ClassNotFoundExceptionNoClassDefFoundErrorusually means that the JVM once tried to instantiate that class but failed on doing it.
So, some tips:
- Look for the first exception with that class.
- Look for some
ExceptionInInitializerErrorbefore theNoClassDefFoundError - Probably the error is in the
staticblocks of your class.
