NoClassDefFoundError

The JVM is unable to find a class

in GUI application when i clik on run button

Can you describe this application and what it does when the "run" button is pressed?
Is it your program or an IDE?

Your posting has left off some of the information in the error message. Can you do it again and get ALL of the text of the error message?

the application is "screentemplate Xmlgenerator". so actually when i press run button it should generate a xml file.and msg also that xml is generated successfully. but as i press run button nothing hapens and in the cmd prompt it shows these exceptions.
actually this class is present in that desired location.

Is the application a java program that you are working with? Does it require libraries/jar files that you do not have?

no actually this is the only message.yes i m using java.and i have all the related jar files on the proper path.

Not until you learn to post a complete stack trace and adequate information about the code that produced it.
