[Jython-users] Jython 2.0b1 imports failed (CNF), worked in JPython

[Brad C. <bk...@mu...>]

I'm writing a Console Snapin for Novell's Console One application.

I had this working in JPython (last rev), but recompiling with Jython 
2.0b1 produces a .class that fails to function. 

Unfortunately I did my earlier work using ConsoleOne 1.2c, but 
upgraded to 1.2d at the same time I switched to Jython. (stupid, I know).

I don't think the ConsoleOne upgrade is related to the failure.

Anyway, here's the scoop.

1. The Python code fragment:

from com.novell.application.console.snapin import Registration
from com.novell.application.console.snapin import RegistrationItem
from com.novell.application.console.snapin import scope
from com.novell.application.console.snapin import Shell

from com.novell.admin.ns.nds import NDSNamespace
from jarray import array

class   FTPDSnapin_Registration(Registration):
    def __init__(self):
        pass
    def getRegistration(self):
        "@sig public com.novell.application.console.snapin.RegistrationItem[] getRegistration()"
        myscope = scope.NamespaceTypeScope(Shell.SNAPIN_PAGE,NDSNamespace.name,"User")
        info = array([RegistrationItem(myscope,"com.MurkWorks.FTPD.FTPDSnapin_PageSnapin")],RegistrationItem)
        return info



2. The import that's failing is 

from com.novell.admin.ns.nds import NDSNamespace

This class is in ConsoleOne.jar, which is in my classpath.

Running jython interactively produces this:

Jython 2.0beta1 on java1.3.0 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from com.novell.admin.ns.nds import NDSNamespace
>>> NDSNamespace.name
'NDS'
>>>

So the import works interactively.

3. I use jythonc to create a deep .jar and have it loaded by ConsoleOne. 
ConsoleOne produces this diagnostic info:

Reordered classpath = 
..\ConsoleOne.jar;..\ConsoleOneCore.jar;..\ConsoleOneExt\collections.ja
r;..\ConsoleOneExt\jgl3.1.0.jar;..\ConsoleOneExt\jh.jar;..\ConsoleOneEx
t\Widgets.jar;..\help;..\ConsoleOneExt\njha.jar;..\ConsoleOneExt\jclient.j
ar;..\ConsoleOneExt\jndi.jar;..\ConsoleOneExt\njcl.jar;..\ConsoleOneExt\
NWFS.jar;..\ConsoleOneExt\JReportBeans.zip


(note that ConsoleOne.jar is in the classpath)

Then this exception:

4. I'm using jdk 1.3

Any suggestions?
