Answer 1

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.
