Jython having issue importing weblogic modules for changing passwords

Question

I am trying to import some WLST modules into a Jython script as outline in the documentation at http://e-docs.bea.com/wls/docs92/config_scripting/config_WLS.html#wp1019971
The strange thing is that it says it is a WLST script, but it appears to be a Jython script. I tried performing this import using WLST interactive mode, but this did not work.
I am passing the passwords as encrypted strings while using the encrypt() function
Here is the script:
import sys
from weblogic.management.security.authentication import UserPasswordEditorMBean
#To be invoked by java -cp /usr/local/bea/wlserver_10.0/common/lib/jython.jar org.python.util.jython
#usage: wlst.sh ResetWLPassword.py <current_pass> <user> <new_pass> <adminServerURL>
#{3DES}/asdfadsf== -
#{3DES}asdfafdsadsf== -
myPass = sys.argv[1]
myUser = sys.argv[2]
newPass = sys.argv[3]
adminServerURL = sys.argv[4]
#Connect
try:
connect('weblogic',myPass,adminServerURL)
except:
print "Could not connect using supplied credentials"
dumpStack()
try:
print "Changing password ..."
atnr=cmo.getSecurityConfiguration().getDefaultRealm().lookupAuthenticationProvider("DefaultAuthenticator")
atnr.changeUserPassword(myUser,myuser,newPass)
print "Changed password successfully"
except:
print "Password change failed"
dumpStack()
I am receiving the following error message:
java -cp /usr/local/bea/wlserver_10.0/common/lib/jython.jar org.python.util.jython /tmp/ResetWLPassword.py "{3DES}/adsfadsfadsf==" weblogic "{3DES}asdfadsfasd== " t3://localhost:7003
sys-package-mgr: can't create package cache dir, '/usr/local/bea/wlserver_10.0/common/lib/cachedir/packages'

You are calling org.python.util.jython again instead of weblogic.WLST like I advised in my first post. Invoke WLST (not jython) and pass your values in cleartext. Like I said in my previous post, I was able to execute your script without issue when calling WLST and passing cleartext values (I did have to modify one line to due a bug in your script -- see my prior posts).This seems to work in terms of getting the code to run, but there is still a problem with passing the arguments to the changeUserPassword() method.
I entered the sequence of commands in the script manually into WLST and it works without issue. It even works without the import, which is strange that Oracle includes it in their documentation.
I am going to post the code here, perhaps there is something wrong syntax-wise with the way I am authenticating, but I can't put my finger on it.
import sys
from weblogic.management.security.authentication import UserPasswordEditorMBean
myPass = sys.argv[1]
myUser = sys.argv[2]
newPass = sys.argv[3]
adminServerURL = sys.argv[4]
#Connect
try:
connect(myUser,myPass,adminServerURL)
except:
print "Could not connect using supplied credentials"
dumpStack()
try:
print "Changing password ..."
atnr=cmo.getSecurityConfiguration().getDefaultRealm().lookupAuthenticationProvider("DefaultAuthenticator")
#atnr.changeUserPassword('weblogic','weblogic','12345678')
atnr.changeUserPassword(myUser,myPass,newPass)
print "Changed password successfully"
except:
print "Password change failed"
dumpStack()
throws:
