On my system, I do: JAVA6_HOME=c:\sdks\jdk1.6.0_18 JAVA_HOME=%JAVA6_HOME% PATH=%PATH%;%JAVA_HOME%\bin –Dilum Ranatunga Jun 13 '11 at 22:44 add a comment| 20 Answers 20 active oldest votes up vote 53 down vote I found one another common reason. If you create the java file inside a package using IDE like eclipse, you will find the package name on the top of your java file like "package pkgName". If you try to run this file from command prompt, you will get the NoClassDefFoundError error. Remove the package name from the java file and use the commands in the command prompt. Wasted 3 hours for this. -- Abhi share|improve this answer answered Nov 2 '13 at 15:57 Abhi 53142 3 But how can i run it from the command prompt without removing the package name, i need the package name

I've tried both the example in Oracle's Java Tutorials. They both compile fine, but at run-time, both come up with this error: Exception in thread "main" java.lang.NoClassDefFoundError: graphics/shapes/Square at Main.main(Main.java:7) Caused by: java.lang.ClassNotFoundException: graphics.shapes.Square at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 1 more I think I might have the Main.java file in the wrong folder.

This article is part 2 of our NoClassDefFoundError troubleshooting series. It will focus and describe the simplest type of NoClassDefFoundError problem. This article is ideal for Java beginners and I highly recommend that you compile and run the sample Java program yourself. The following writing format will be used going forward and will provide you with: - Description of the problem case and type of NoClassDefFoundError- Sample Java program “simulating” the problem case- ClassLoader chain view- Recommendations and resolution strategies NoClassDefFoundError problem case 1 – missing JAR file The first problem case we will cover is related to a Java program packaging and / or classpath problem. A typical Java program can include one or many JAR files created at compile time. NoClassDefFoundError can often be observed when you forget to add JAR file(s) containing Java classes referenced by your Java or Java EE application. This type of problem is normally not hard to resolve once you analyze the Java Exception and missing Java class name. Sample Java program The following simple Java program is split as per below: - The main Java program NoClassDefFoundErrorSimulator- The caller Java class CallerClassA- The referencing Java class ReferencingClassA- A util class for ClassLoader and logging related facilities JavaEETrainingUtil This program is simple
