Cannot use supercsv while running a jar file in Java (windows)

Question

When I give the following command

java -Xmx500m -jar bc.jar %1 %2 %3 %4 %5 %6 %7 %8 %9

I am getting the following Exception

    Throwable Error: java.lang.NoClassDefFoundError: org/supercsv/prefs/CsvPreference

I guess that this is due to the improper inclusion of supercsv.

Can anybody help me fixing this?

Sounds like Super CSV isn't on the classpath, and as you're not supplying the classpath with -cp I would check the manifest in your jar to see where it expects the super-csv jar to be (probably in the same directory), then confirm that it's actually there.

This seems to be a fairly good overview of the different ways of configuring the classpath when running jars.
