No WLST cachedir with python.cachedir.skip

Friday, September 11th, 2009

In one of my previous post I have talked about python.cachedir and how it may cause some errors during WLST/Jython initialization.
With WebLogic 11g Oracle has upgraded the Jython Version from 2.1 to 2.2 (see my post here), which opens up yet another way of getting rid of these errors. In fact you can get rid of the cachedir entirely by starting WLST with -Dpython.cachedir.skip=true, this will instruct Jython not to create the CacheDir.
I haven’t done extensive testing with this option but so far I haven’t seen any issues by not creating this cachedir.

Traceback (innermost last):
File “<iostream>”, line 12, in ?
ImportError: no module named java
