I have a script in a Work Order Management System (Maximo) that performs a spatial query.

Details:

1. Takes the X&Y coordinates of a work order in Maximo
2. Generates a URL from the coordinates (including other spatial query information)
3. Executes the URL via a separate script/library (LIB_HTTPCLIENT)
4. Performs a spatial query in an ESRI REST feature service (in a separate GIS system)
5. JSON text is returned to Maximo with the attributes of the zone that the work order intersected
6. The zone number is parsed from the JSON text via a separate script/library (LIB_PARSE_JSON)
7. Inserts the zone number into the work order record

Jython main automation script

from psdi.mbo import MboConstants
from java.util import HashMap

#Get the y and x coordinates(UTM projection) from the WOSERVICEADDRESS table via the SERVICEADDRESS system relationship
#The datatype of the LatitydeY and LongitudeX is decimal: 1234567.8335815760, 123456.4075621164
#Convert the decimals to integers, and then strings, for the purpose of generating the URL (I don't think the URL can have decimal places)
laty = str(mbo.getInt("SERVICEADDRESS.LatitudeY"))
longx = str(mbo.getInt("SERVICEADDRESS.LONGITUDEX"))

#Verify if the numbers are legitimate UTM coordinates
if len(laty) == 7 and len(longx) == 6:
    #Assemble the URL (including the longx and the laty). Note: The coordinates are flipped in the url
    url="http://something.com/arcgis/rest/services/something/Zones/MapServer/15/query?geometry=" + longx + "%2C" + laty + "&geometryType=esriGeometryPoint&spatialRel=esriSpatialRelIntersects&outFields=*&returnGeometry=false&f=pjson"
    #Get the JSON text from the feature service (the JSON text contains the zone value)
    ctx = HashMap()
    ctx.put("url",url)
    service.invokeScript("LIB_HTTPCLIENT",ctx)
    json_text = str(ctx.get("response"))

    #Parse the zone value from the JSON text
    ctx = HashMap()
    ctx.put("json_text",json_text)
    service.invokeScript("LIB_PARSE_JSON",ctx)
    parsed_val = str(ctx.get("parsed_val"))

    #Enter the zone value into the zone field in the work order
    mbo.setValue("DESCRIPTION","Waste Zone: "+parsed_val,MboConstants.NOACCESSCHECK)

Jython library (LIB_HTTPCLIENT)

from psdi.iface.router import HTTPHandler
from java.util import HashMap
from java.lang import String
handler = HTTPHandler()
map = HashMap()
map.put("URL",url)
map.put("HTTPMETHOD","GET")
responseBytes = handler.invoke(map,None)
response = String(responseBytes,"utf-8")

JavaScript library (LIB_PARSE_JSON)

#The field name (ZONE) is hardcoded in the LIB_PARSE_JSON. I'm not sure if this is best practice or not.
var obj = JSON.parse(json_text);
parsed_val = obj.features[0].attributes.ZONE

How can this code be improved?
