Inserting '.' in front of sys.path from java:

interpr.exec("sys.path[0:0] = ['.']");

Removing it afterwards:

interpr.exec("del sys.path[0]");

Basically write the wrapping code statements in jython
have your interpr execute these one by one.
Similar for sys.argv.

In case you want to make sure sys.path is the same afterwards
use try/finally in java:

interpr.exec("sys.path[0:0] = ['.']");
try {
interpr.exec('yourcode.py');
} finally {
interpr.exec("del sys.path[0]");
}

>Sorry for the newbie questions...I really appreciate your time taken to answer this.

It's not newbie stuff, but it keeps popping up. Embedding jython
seems to be popular these days.

Ype
