Re: [staf-users] Debugging Jython In Stax

[Sharon L. <lu...@us...>]

I tried to recreate the problem but it worked fine for me.  I created a 
STAX job that called execfile to run a .py file within a <script> element. 
 The .py file's print statement appeared in the STAX Job User Log and in 
the STAX Monitor messages just like print statements that are contained 
directly within a <script> element.  If you doing something different, let 
me know.  Here's the STAX job and .py file that I ran:

Contents of C:\stax\testScriptFile.py:

print 'Printed by testScriptFile.py'

Contents of C:\stax\execFile.xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">

<stax>

  <defaultcall function="Main"/>

  <function name="Main" scope="local">
    <sequence>
      <script>
        print 'Printed by script element in job'
        execfile('C:/stax/testScriptFile.py')
      </script>
    </sequence>
  </function>
</stax>

Here's the STAX Job Log User file output: (these message also appeared in 
the STAX Monitor's Messages panel)

C:\>STAF local LOG QUERY MACHINE {STAF/Config/MachineNickname} LOGNAME

set to "JobUserLogAndMsg":

I'm not sure what you mean by the "jython routines".  Please provide a 
STAX job that provides an example of  printing from "jython routines".

Is the output being logged to the STAX JVM Log?  There's a link to view 
the STAX JVM Log via the STAX Job Monitor.

Hi Guys,
I have a jython file with several routines in it called from a stax xml 
file.   I think something is wrong with a string handler in the jython 
code, and would like to get some debug information about it.

I changed the stax service definition in the staf.cfg file to the 
following:

SERVICE STAX LIBRARY JSTAF EXECUTE 
{STAF/Config/STAFRoot}/services/stax/STAX.jar PARMS "PYTHONOUTPUT 
JobUserLogAndMsg CLEARLOGS Enabled PYTHONLOGLEVEL info" $

I am getting good debug data from print statements in the <script> areas 
of my XML code. *But*, I am not getting any output from "print" that is 
anywhere in the jython routines.

How can I get the jython code to print debug data?

Tks,
