[Jython-users] case sensitivity of object names & packages?

[Tom W. <to...@ss...>]

I've run into a situation where I want to:

from visad.data.mcidas import PointData

and there is an object named "visad.Data" which is confusing the class loader
somewhere along the line (big stack trace follows...sorry).

I cannot change the names in this library, so I'm hoping someone has a
suggestion as to how I can work around this.  I've tried some permutations, but
nothing seems to work via Jython.  I'm running Windoz and Jython 2.0.

Sorry if this has been answered before, but a bit of searching did not turn up
anything...

Thanks...
