For debugging mismatched jars, first build a list of the jars in question, then run jwhich to discover the jar that provides a specific Java class. Put the jar and the script provided in the download in a directory on your PATH such as /usr/local/bin.

For *nix and Mac, build the list of jars under the current directory like this:

Shell

export CLASSPATH=$(find . -name \*.jar -printf %h/%p:)

For Cygwin, build the list of jars under the current directory like this:

Shell

export CLASSPATH=$(find . -name \*.jar -printf '%h/%p;')

Run the script like this:
