Initializing WebLogic Scripting Tool (WLST) ...

Problem invoking WLST - Traceback (innermost last):

Need to do the security configuration first!
The fix
Not sure what causes it; my first impression was that too many files, or a certain type of file upset jython, as the script finished without a glitch when called in another directory.Also, tarring, and subsequent cleaning of the directory where the script is executed (that is: started from) seemed to help. So, if you're in this situation, and switching directories cures the problem, clean out the directory you use when calling the script.
XML?
Later, a collegue of mine narrowed it down to the existance of an XML subdirectory. Renaming that cured the problem, too.Hope this helps someone.
Oh - and "dom" means dumb in Dutch - hence the title. And the cause for this error, of course...
