No Class deffinition found jboss: java.lang.NoClassDefFoundError: org/jboss/kernel/Kernel

Hello I am having a probl开发者_StackOverflow社区em using jboss from command line, i get the following error:

ERROR [AbstractKernelController] Error installing to PreInstall: name=WSKernelLocator state=Real java.lang.NoClassDefFoundError: org/jboss/kernel/Kernel

Any reply will be appreciated. Thanks

Hmm, maybe JBoss archive was not unzipped properly? If you are working on Windows do not use built-in unzipper, it fails for larger archives. Use 7-Zip, WinRar, Total Commander, etc.
