  • You haven't put any part of the tool in your classpath, so of course the class won't be found. Please learn about -cp and classpaths and apply what you learn to this problem. – bmargulies Oct 11 '11 at 18:42
  • thats the thing that puzzle me i tried cp like this **/path-to-java/bin/java -cp /path-to-grinder/lib/grinder.jar** also i tried export **export CLASSPATH=$CLASSPATH:/path-to-grinder/lib/grinder.jar** but i still have this issue. – Jack Oct 11 '11 at 18:47
  • You didn't write that in the question. – bmargulies Oct 11 '11 at 18:53

Grinder has a much longer classpath than just 'grinder.jar'. You need all the dependencies on the classpath, too. (e.g. picocontainer)

If the grinder jar has a MANIFEST.MF, it might list them, in which case those jars just have to be sitting in the same directory as the grinder jar. If not, you need to set the classpath to include them.

The specific error message you are showing will be fixed by adding picocontainer-.jar to your classpath. But you will probably need to include everything in the grinder lib dir on your classpath to get things working properly.
