You gave too few information on your setting
(classpath vs python.path content etc)
but for sure the above should simply be

python.path = .;g:\\poi\\build\\poi.jar

I have not made my head around of the above
produce but anyway not something useful.

the warning I imagine refer to Python module and packages
access from jar, not to Java classes!

ask again if the above does not solve the issue,
in that case saying what is in classpath
and what is your cwd could help too.
