I am having trouble importing from a JAR file in custom authentication. The name of the jar is ed.jar and below is a code snippet that works in Jython (tested by running in my system): ``` import os,glob,sys, site from org.python.util import jython for jar in glob.glob(os.path.join(directory,'*.jar')): #directory contains the ed.jar to import as well as its depencies sys.path.append(jar) import ed #ed is the JAR to import. ``` I added the same above lines to a custom script in Gluu: ``` from java.util import Arrays from org.apache.http.params import CoreConnectionPNames from org.xdi.service.cdi.util import CdiUtil from org.xdi.oxauth.security import Identity from org.xdi.model.custom.script.type.auth import PersonAuthenticationType from org.xdi.oxauth.model.config import ConfigurationFactory from org.xdi.oxauth.service import UserService, AuthenticationService, SessionIdService from org.xdi.oxauth.service.net import HttpService from org.xdi.oxauth.util import ServerUtil from org.xdi.util import StringHelper from org.xdi.oxauth.service import EncryptionService from java.util import Arrays, HashMap, IdentityHashMap import java import datetime import urllib import sys import json #code that I added starts here import os,glob,site from org.python.util import jython #the next few lines find the location of directory containing the jar files jar_location = jython().getClass().getProtectionDomain().getCodeSource().getLocation().getPath() jar_location = jar_location.rsplit("/",1)[0] directory = jar_location + '/external/' #add all the jars as done in previous code for jar in glob.glob(os.path.join(directory,'*.jar')): sys.path.append(jar) import ed class PersonAuthentication(PersonAuthenticationType): ``` I get the following error (in oxauth_script.log): ``` org.python.core.PyException: null at org.python.core.Py.ImportError(Py.java:334) ~[jython-standalone-2.7.1.jar:?] at org.python.core.imp.import_first(imp.java:879)
