我正在尝试使用 Jconn4 和 jaydebeapi 包连接到 IBM OMNIBUS 对象服务器数据库，但是我不断收到

jpype._jexception.RuntimeExceptionPyRaisable：java.lang.RuntimeException：找不到类 com.sybase.jdbc4.jdbc.SybDriver

我尝试将 jconn4.jar 移动到安装 java 的位置并更改代码中的路径

import jaydebeapi
import os
import jpype                                                                                                                                                                                                                     
conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', ['jdbc:sybase:Tds:ip:4100/alerts','user','pass'],['/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar'])
curs = conn.cursor()

我的输出看起来像

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', ['jdbc:sybase:Tds:ip:4100/alerts','user','pass'],['/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar'])

我相信连接函数参数是：类名、URL、args、jar 路径。

你可以试试：

conn = jaydebeapi.connect('com.sybase.jdbc4.jdbc.SybDriver', 'jdbc:sybase:Tds:ip:4100/alerts', {'user': 'user', 'password': 'pass'}, '/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/lib/jconn4.jar')
