Re: [Jython-users] calling Jython in Windows7: difference between calling jython.exe and jython.jar

[Niemann, H. <har...@si...>]

Hi Jeff and Stefan,

THANKSALOT!

calling the interpreter class instead of it's jar file

	%java32% -cp %CLASSPATH% -Dpython.path=%CLASSPATH% org.python.util.jython diagtest.py

works perfectly.

The jython.exe --print helped me, too.

The class path ought to be ignored (by Java) if you supply -jar.

Stefan's solution of putting the Jython JAR on the path and invoking the main program looks good to me.

The jython.exe launcher takes a --print option that shows you fairly accurately what it would have launched had you not given that option, and this is a good way to get a prototype Java command line. It is not quite accurate for PowerShell: it seems more elements have to be protected by quoting (e.g. "-Dprop=val").
