Calling wlst commands from utility script?

Question

Hi all,
I'm trying to write some utility functions to wrap things like create() and delete() with some error handling code. So I would have a module like utils.py and it would contain methods like myDelete(), myCreate(), etc. I would like them to then call WLST's delete() and create(). Then I would have a script that creates and deletes queues, for example, that would use utils.myDelete() etc. However this doesn't work and I can't figure out why.
If I just reference the wlst commands directly, I get "Name Error: cd."
If I import
from weblogic.management.scripting import WLScriptContext as wlst
WLST = wlst()
I get "... Unknown error...Use dumpStack()..." But dumpStack()'s output is empty.
If I extract wlstModule.py from the jar file and try importing it, I get "no module named wlstModule."
Suggestions?
thanks

Hello John,
Here are the steps you can follow to import wlst into other jython modules.
Extract wlstModule.py from the jar or you can also use the command writeIniFile(<file-path>) for WLST to write out the module file. Place wlstModule.py in the directory where you are going to invoke jython from or where you have your other utility scripts. In your utility script you should import the module as
import wlstModule
And in the script wherever you would like to call any wlst commands you should use wlstModule.<command>. Also use straight jython while invoking the scripts as
java org.python.util.jython instead of java weblogic.WLST.
