Re: Exception in thread "main" java.lang.NoClassDefFoundError: javax/jcr/Repository

Shouting will not help, it tends to distort your voice and no one can hear what you are saying :). fortunately I turned the volume down before opening your email (just this once). 

The you are having is a classpath problem.

IIRC
"java -cp ."

will remove $CLASSPATH from the classpath

try adding . to the start of the CLASSPATH.

If that fails read [1] or [2]

and what i have found is when i execute both the programs then bug is
coming
from javax package
javax/jcr/repository  and javax/jcr/credential
and both class files are within javax package and that package is within 
jcr-1.0.jar file

please please tell i'm waiting for your reply
and please tell me in detail


Thank you
