[Jython-users] embedded Jython and capturing script output

[Hugh R. <rod...@ag...>]

Hello -

I have written a Java GUI that loads a Jython script and then attempts to run it
using an embedded Jython interpreter, i.e., the PythonInterpreter class and/or
the InteractiveInterpreter class.

I have been unable to capture the output of the script as it runs so I can
display its progress in my Java GUI. Using the InteractiveInterpreter I sent the
Jython script to the embedded interpreter line-by-line and caputer the output by
using the setOut() method with a StringWriter output stream. This worked for the
"topmost" Jython script, but when the executing script called my functions that
were defined in another Jython script (which it found), the output stopped being
retrieved until the entire script ran to completion. And I have yet to figure
out how to capture the output when I use the PythonInterpreter.exec(String s)
method.

Any ideas? I'm stumped.

Thanks!

Hugh
