exception when running jar, NoClassDefFoundError:org/springframework/context/ApplicationContext

Question

I have a spring project, it runs well in eclipse. But when i package it as a executable jar file and run it with command java -jar jar-name, it reports the following exception.

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/c
ontext/ApplicationContext
Caused by: java.lang.ClassNotFoundException: org.springframework.context.Applica
tionContext
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: cloud.ras.alert.RASAlertApp. Program will exit.

And even if i set the class-path value with springframework path, it still doesn't work. And can anyone give me a help? Many thanks.

It is failing to load Springs jar files, are you sure that you have all your external libraries included in the build path? — ObieMD5

do you mean that i should config the build path in manifest file? — Bryant

Yes, you need to set the classpath while compiling, and also while running. — nook

Can you elaborate on what you mean by "springframework path"? — Gus

Right click on project -> Export -> select Runnable Jar ->click Next in wizard -> Select "Copy Required Library into a sub folder next to the generated jar and click Finish.

Since the jar is not able to find your relevant jar as runnable jar, you are facing this issue.

IMP: Make sure you are using Eclipse JUNO.I am not sure with other versions of eclipse

I was using Eclipse Ganymede and it does not has the option to select "Library Handling" option in the wizard page.

Works for Eclispe Mars! The goal is to select 'Runnable Jar File' and not the first option 'JAR file'.

Why don't double check your classpath? And you could try to add the jar path to you command as below: java -cp .;jar_path_spring -jar jar-name
