I create a new jar file. when i run the jar using 

java -jar UpdateAvailable.jar com.dao.mysql.UpdateAvailable

I got the following exception.

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/jettison/json/JSONException
Caused by: java.lang.ClassNotFoundException: org.codehaus.jettison.json.JSONException
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

But I copied all the supporting jars inside the UpdateAvailable.jar. Now what my requirement is run the jar file with out specifying supporting jars, like

java -jar UpdateAvailable.jar com.dao.mysql.UpdateAvailable

    java -jar UpdateAvailable.jar com.dao.mysql.UpdateAvailable
