Question regarding passing external commandline arguements

I am new to Jython . I have the following .py file . This has been created based on BEA’s doc. I used to create a weblogic domain. I want the py script to be more generic. I run now using

 

Java weblogic.WLST  filename.py

 

But I wanna do something like

 

Java –Denv=devconnect weblogic.WLST filename.py……How do you accomplish this?  This can be done in ant using similar concept like ${keyvalue}

 

Eager to see responses.

 

loadProperties('C:/beacases/627825/wlstoffline9/devconnect.properties')

 

loadProperties('C:/beacases/627825/wlstoffline9/stageconnect.properties')

 

 

loadProperties('C:/beacases/627825/wlstoffline9/prodconnect.properties')

 

import sys

from java.lang import Integer

from java.io import *

 

def storeFile(fileName,fileText):

  try:

    out = FileOutputStream(fileName)

    p = PrintStream(out)

    p.println(fileText);

    # p.println("password=" + password);

    p.close()

    print "File " + fileName + " was created."

  except:

    print "ERROR trying to create: " + fileName

    dumpStack()

   

readTemplate("c:/bea91/weblogic91/common/templates/domains/wls.jar")

 

loadProperties('C:/beacases/627825/wlstoffline9/connect.properties')

 

 

 

domain_home=domain_path+'/' + domainname

print "domain home value", domain_home

 

cd('Servers/AdminServer')

set('Name',dservername)

set('ListenPort',Integer(listenport).intValue())

 

create('AdminServer','SSL')
