c:\lib is lib of groovy. c:\hello is a class hello world. [ July 07, 2008: Message edited by: Bro Fratello ]

Welcome to JavaRanch.
C:\>java -classpath c:\lib\ c:\hello
I don't know much about Groovy, but it probably needs to be
Replace GROOVY.JAR with the name of the Groovy library. Jar files need to be listed explicitly in the classpath; it's not sufficient to list their directory. [ July 07, 2008: Message edited by: Ulf Dittmer ]
Ulf is 99% right. You need more than the single groovy jar file. In one of the distributions there is a groovy-all.jar which can be used otherwise you'll need to have the classpath point to all the jar files under the $GROOVY_HOME/lib folder.
