[Jython-dev] jython exec problem

[J D <jam...@ho...>]

>Can anyone send back with a solution to the problem contained in

>TypeError: __xor__nor__rxor__ defined for these operands

>PythonInterpreter interp = new PythonInterpreter();
>interp.set( "math", new ExtraMath() );
>interp.exec( erpFormula2);

>String erpFormula1 = ("resultant = 10 * math.log10( TransmitPower)");
>String erpFormula2 = ("resultant = 10 ^( TransmitPower )");

>Also as I am new to jython, what is the deal with the __xxxx__ method

>Double newDouble = result.__tojava__( new Double( 0.0 ) ) without success.
