Newbie namespace question

[bcarlso at gmail.com]

Here's my situation, I've created some scripts to configure WebSphere
and the WAS scripting engine assigns the variable AdminConfig to a Java
object.  I have created classes that wrap the AdminConfig settings,
simplifying the interface for those who want to script their server
installs.

At the command line, I pass the main script in and AdminConfig is
automatically assigned and placed in the global namespace and control
is passed to the main script.

Therefore...

#configure_server_foo.py
from jdbc import DataSource

print globals()["AdminConfig"]  # Will print com.ibm.yada.yada.yada

# Create a couple of data sources
ds = DataSource("ServerName")
ds.create("dsname1", "connectionInfo", "etc")
ds.create("dsname2", "connectionInfo", "etc")

Now, in jdbc.py I have

#jdbc.py
class DataSource:
def __init__(self, servername):
self.servername = servername

def create(name, connectionInfo, etc):
#Call the IBM supplied WebSphere config object
AdminConfig.create('DataSource')

Run it and get a name error, which, makes sense.
If I try to use the standard import solution as deelan suggests I have
a circular reference on the imports and I get an error that it can't
import class DataSource (presumbably because it hasn't gotten far
enough through jdbc.py to realize that there's a DataSource class
defined.

Any insight would be greatly appreciated, and thanks to both deelan and
Steve for your help.
