how to compile in jython 2.5b1??

[pellegrinodj]

I have to use jython 2.5b1 couse with the stable version it's not
possible to use sympy library for mathematic operation but the
"jythonc.bat" it's not included.
I look to this link: http://www.jython.org/Project/jythonc.html
"..jythonc is unmaintained and will not be present in its current form
in Jython 2.5..."
so what can I do??
thank you for the answer!!
