It might be helpful for other's working on netbeans. [I am wondering if others facing similar issue would have to wait till next day to restart the computer.. :) just kidding.]Reply I have just tried to compile the .java file and it claims that it cannot find packages, even though the packages are there in same directory! 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
we also posted our problems on stackoverflow . And regarding the classpath: don't touch Websphere's classpath. It is possible that updates have been made to the original version after this document was translated and published. It still says Hello World!

Like in below code example, During class loading and initialization User class are throwing Exception from static initializer block, which trigger ExceptionInInitializerError during first time loading of User class in response http://internetmairie.com/servlet-error/servlet-error-java-lang-classnotfoundexception.html If you are running your Java program in a multi-user operating system like Linux then you should be using application user id for all your application resources like JAR files, libraries, Is cardinality a well defined function? Why are you suggesting to place libraries in JRE/lib?
I ran it to make sure everything works okay before I make changes to it and incorporate it into my project. This time, you will get java.lang.NoClassDefFoundError directly without java.lang.ExceptionInInitializerError and message for NoClassDefFoundError are also just printing the name of the class as testing/User i.e. asked 6 years ago viewed 55724 times active 11 months ago Linked 3 java.lang.NoClassDefFoundError: javax/servlet/http/HttpServletRequest 8 java.lang.NoClassDefFoundError: javax/servlet/http/HttpServletRequest 3 java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet 2 Exception : java.lang.ClassNotFoundException: javax.servlet.http.HttpServletRequest when running Servlet 0 java.lang.NoClassDefFoundError: check over here Your help would be appreciated.
