只需将您的jar添加到sys.path中，就像这样:

Just add your jar to sys.path, like this:

~ $ jython
Jython 2.5.0+ (trunk:6691, Aug 17 2009, 17:09:38) 
[Java HotSpot(TM) Client VM (Apple Computer, Inc.)] on java1.6.0-dp
Type "help", "copyright", "credits" or "license" for more information.
>>> from org.thobe.somepackage import SomeClass # not possible to import yet
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named thobe
>>> import sys
>>> sys.path.append("/var/javalib/some-thobe-package.jar") # add the jar to your path
>>> from org.thobe.somepackage import SomeClass # it's now possible to import the package
>>> some_object = SomeClass() # You can now use your java class

没有比这更简单的了:)

It couldn't get more simple than that :)

在您的情况下，您可能想使用包装的路径来找到罐子:

In your case you probably want to use the path of your package to find the jar:

# yourpackage/__init__.py

import sys, os
if 'java' in sys.platform.lower():
    sys.path.append(os.path.join(os.path.dirname(os.path.abspath(__file__)),
                                 "your-lib.jar"))
    from jython_implementation import library
else:
    from cpython_implementation import library

希望有帮助！
