[Jython-users] jreload import problem

[Updike, C. <Cla...@jh...>]

I'm trying to load a JDBC driver programatically with jreload (without
putting it on the jvm's classpath when starting jython).  When I try to
import the driver class I get a ClassFormatError, possibly suggesting the
thing I'm actually importing isn't really a class:

>>> 	import sys, jreload
>>> 	from com.ziclix.python.sql import zxJDBC
>>> 	ls = jreload.makeLoadSet('oracleLS',['pathToJar/classes12.jar'])
>>> 	from oracleLS.oracle.jdbc.driver import OracleDriver
Traceback (most recent call last):
java.lang.ClassFormatError: java.lang.ClassFormatError:
oracle/jdbc/driver/OracleDriver (Illegal UTF8 string in constant pool)

But, if I do the following:

>>> 	from oracleLS.oracle.jdbc import driver
>>> 	dir(driver)

It shows me that the class is in the driver package:

['ArrayDataResultSet', 'ArrayLocatorResultSet', 'BaseResultSet',
   <snip>
'OracleDriver', 'OracleInputStream', 'OracleLog', 
   <snip>
'UpdatableResultSet', '__name__']

I have inspected this jar file and there truly is a OracleDriver.class in
the oracle.jdbc.driver package.

Any ideas what I'm doing wrong?

TIA,
