Re: [Jython-users] new jython user stumped

The problem is you're passing a String (containing a space-separated
list of strings) into a method that expects a String array.

try:
...main( string.split( "10 100" ))

tuples or lists of strings should be coerced automatically to String
arrays.  For some complex cases involving arrays, you may need to
investigate the jarray module, but most of the time the automatic
coercion of sequences to arrays works fine.
