There is a bug in jreload where it doesn't load the entire class file,
thereby resulting in an invalid class/ClassFormatError. I have submitted
a patch which fixes this, and you can get it by browsing the bug database
for jython on sourceforge -

Subject: [Jython-users] jreload import problem
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,
Clark
