It worked! I have seen it a couple of times and spent quite a lot time initially to figure out what is wrong, which class is missing etc.

whereas the classes are being generated. For example, if we have a method call from a class or accessing any static member of a Class and that class is not available during run-time then JVM will throw The class is not in Classpath, there is no sure shot way of knowing it but many times you can just have a look to print System.getproperty("java.classpath")and it will print the i am having the same kind of problem when running jdbc with servlet......the error msg is...java.lang.NoClassDefFoundError: studentsCaused by: java.lang.ClassNotFoundException: HelloWorldat java.net.URLClassLoader$1.run(URLClassLoader.java:200)at java.security.AccessController.doPrivileged(Native Method)at java.net.URLClassLoader.findClass(URLClassLoader.java:188)at java.lang.ClassLoader.loadClass(ClassLoader.java:307)at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)at java.lang.ClassLoader.loadClass(ClassLoader.java:252)at java.lang.ClassLoader.loadClass Internal(ClassLoader.java:320Exception in thread
