import java ImportError: No module named java

问题

I seemed to have hit a roadblock and can't figure this out at all, can anyone help me figure out why I am unable to import the java module?

Error:

Traceback (most recent call last):
  File "./datasource_config.py", line 3, in ?
    import java
ImportError: No module named java

java:

13:30:05 # which java
/usr/bin/java

beginning of script

#!/usr/bin/python
import sys
import java
from java.util import Properties
from java.io import FileInputStream
from org.python.modules import time
lineSep = java.lang.System.getProperty('line.separator')

def datasource(cluster,user,password,url,env,jdbc_driver,timeOut,maxConn,minConn,reapTime,unusdTimeout,agedTimeout):

    #Declare global variables 
    global    AdminConfig 
    global    AdminControl

Can someone help me determine what this means?

13:45:07 # ./jython -v /opt/websphere/datasource_config.py

回答1:

The error is misleading here. The problem is likely to be that you dont have permissions in directory /usr/lib/jython-25/cachedir/packages and possibly the parent directory cachedir too. If you look at the first line of the output when wsadmin.sh starts, it actually implies this.
