Re: [Jython-users] [Q] newbie's question on Jython

[Robert W. B. <rb...@di...>]

The example I sent has at least 2 errors that need corrected.

   error 1- The "embed.test()" line should read "embed.useInterp()".

   error 2- the initialize arguments are wrong

corrections noted below.

sorry about that.

          //CORRECTED initialize method here
          PythonInterpreter.initialize(System.getProperties(), props,
                                       new String[0]);
