java -jar 找不到引用类_java – pyjnius导入jar文件时“找不到类”

我正在尝试使用我从

java应用程序构建的jar文件使pyjnius工作,但我不断收到“找不到类”错误：

>>> import os

>>> os.environ['CLASSPATH'] = "~/workspace/myapp-Tools/Admin/Console/couchdb/myapp-web.jar"

>>> from jnius import autoclass

>>> bla = autoclass('com/myapp/webapp/server/helpers/licensee/CalculationHelper')

Traceback (most recent call last):

File "", line 1, in

File "/home/sam/workspace/myapp-Tools/Admin/Console/couchdb/virtualenv/local/lib/python2.7/site-packages/jnius/reflect.py", line 150, in autoclass

c = find_javaclass(clsname)

File "jnius_export_func.pxi", line 23, in jnius.find_javaclass (jnius/jnius.c:12815)

jnius.JavaException: Class not found 'com/myapp/webapp/server/helpers/licensee/CalculationHelper'

>>>

我当然检查过：

jar tf myapp-web.jar

和com / myapp / webapp / server / helpers / licensee / CalculationHelper.class就在那里

我也试过这样设置类路径：

import jnius_config

jnius_config.set_classpath('.', '~/workspace/myapp-Tools/Admin/Console/couchdb/')

#import jnius

from jnius import autoclass

但这给了我同样的结果.

我正在研究一个虚拟的btw.

我已经尝试过我可以在网上找到的所有方法,但它根本不起作用.我不得不手动安装pyjnius,因为使用pip让我得到了旧版本.

任何帮助将不胜感激.

编辑：尝试使用不是由我创建的jar,我看到一个不同的错误

这是jar上的jar tf的内容：

sam@lambda ~/workspace$jar tf ./someproject/postgresql-8.1-408.jdbc3.jar
