java.lang.NoClassDefFoundError :: Class present at the given path in Tomcat

Question

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

Most of the time java.lang.NoClassDefFoundError is not the actual problem. There should be another exception before that. You should be looking for an exception which happens during the static initialization of the class in the message. Any access to this class will trigger NoClassDefFound but it means only that the class fails to initialize. — jdb, Jan 25 '13 at 09:47
Actually there is no Exception before this exception. for debugging purpose I tried adding static block & printing statement inside static block But it never get executed — Harry K, Jan 25 '13 at 10:01
make sure you have your jasper related jars in tomcat classpath. — Sajan Chandran, Jan 25 '13 at 10:02
Are there any static fields in this class com.abcd.framework.web.servicelocator.ServiceLocator? — jdb, Jan 25 '13 at 10:09
Are the jasper jars in your webapp, under WEB-INF/lib, or are they in Tomcat's classpath? They should be in WEB-INF/lib. — JB Nizet, Jan 25 '13 at 10:25
All the Jasper related JARs are present in tomcat/WEb-INF/lib directory The ServiceLocator is singleton class ....so the Only static field is instance variable of ServiceLocator itself — Harry K, Jan 25 '13 at 10:57
You mean in your webapp's WEB-INF/lib? Tomcat doesn't have a WEB-INF directory. — JB Nizet, Jan 25 '13 at 11:01

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.

Some clarifications:

NoClassDefFoundError != ClassNotFoundException
NoClassDefFoundError usually 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 ExceptionInInitializerError before the NoClassDefFoundError
Probably the error is in the static blocks of your class.
