[1.0.1] Importing java only includes __name__ and io

I do not know ;-)

But why is this of relevance?

All Java imports work as expected

from java.lang import System as JSys
print JSys.getProperty("user.home")

Maybe just for convenience? :) Stand-alone jython works that way. Sikuli 1.0.0 also works the same way.

Also, I was trying to use zxJDBC and tried to follow what was discussed in https://answers.launchpad.net/sikuli/+question/135452.

Like to verify if the classpath is correct, do:

import java
java.lang.System.getProperty('java.class.path')

The usage of Sikuli with Jython standalone is easier now with sikuli-java.jar (setup option 4) from version 1.0.1.

This needs only to be on class path and does not contain the Jython interpreter (like sikuli-script.jar).

when you say in your main script:
import org.sikuli.basics.SikuliXforJython
from sikuli import *

it even sets the sys.path correctly on the fly at runtime.
