Code:

/opt/jboss-5.1.0.GA/bin/twiddle.sh -s localhost get jboss.system:type=ServerInfo ActiveThreadCount

i get this error:

Code:

so the same error as here above?!
is it possible that my twiddle files (because i have also a twiddle.jar and twiddle.bat file) are corrupt or incomplete?

Help is much appreciated :p

Thanks in advance
