How could I solve this problem?

Answer 1

You can change the location of the cache directory to a place that you have read & write access to by setting the "python.cachedir" option when starting jython, e.g.:

jython -Dpython.cachedir=*your cachedir directory here*

or:

java -jar my_standalone_jython.jar -Dpython.cachedir=*your cachedir directory here*

You can read about the python.cachedir option here: http://www.jython.org/archive/21/docs/registry.html

Answer 2

1) By changing permissions to allow writing to the directory in the error message.

2) By setting python.cachedir.skip = true
