Accessing wsadmin objects via Jython

Question

I'm trying to access the Admin objects via a Jython script in order to update a Maven app deployed to a WebSphere Application Server without having to march through the Integrated Solutions Console every time I make a change. My question is simple: I know how to invoke the commands once I access the Admin objects, but I'm having difficulty getting that far. Once I'm in the bin folder of my server profile, do I need to assign them to objects, or can I just call them directly? And how, specifically, would I do that? Here's the code I have now:

#!usr/bin/local/python

import sys
import os

try:
    serverPath = 'c:\IBM\WebSphere8\AppServerND\profiles\\WAS8\\bin\\'
    os.chdir(serverPath)
    print AdminApp.listModules('restreportscore-application')
except:
    e = sys.exc_info()[0]
    print( "Error: %s" % e )
    endSelect = raw_input("Press Enter to continue...")

But it's throwing an error of type 'exceptions.NameError.'

It doesn't work the way it looks like you think it works. The jython interface mirrors the cmd line actions, but isn't the same. You call a jython script like this:

sudo /opt/IBM/WebSphere/AppServer/bin/wsadmin.sh lang jython -f ./trecs-installer.py

So it already knows "where" it is. At that point you execute your commands through the AdminApp, AdminConfig and AdminTask APIs like this:

AdminApp.install(earDir + "trecs.ear", "[" + settings + ' -MapModulesToServers [' + mapModulesToServers + '] -MapRolesToUsers [' + mapRolesToUsers + "]")

or

# Add destinations and queues...
for item in trecsQueues:
    if isNetworkDeploy:
            AdminTask.createSIBDestination("[-bus " + trecsBus + " -name " + item + " -type Queue -reliability ASSURED_PERSISTENT -cluster " + clusterName + ']')
            AdminTask.createSIBJMSQueue(clusterLongName, "[-name " + item + " -jndiName queue/" + item + " -busName " + trecsBus + " -queueName "  + item + ']')
    else:
            AdminTask.createSIBDestination("[-bus " + trecsBus + " -name " + item + " -type Queue -reliability ASSURED_PERSISTENT -node " + nodeName + ' -server ' + serverName + ']')
            AdminTask.createSIBJMSQueue(serverLongName, "[-name " + item + " -jndiName queue/" + item + " -busName " + trecsBus + " -queueName "  + item + ']')
