NullPointerException during ORB

NullPointerException during ORB_init

I've spent ages searching on Google and several newsgroups for an
answer but sadly with no success.

I get an NPE when I try to create my ORB - I'm pretty sure its going
to be down to some config error but the exception isn't helpful at
all. Here is some logging from the app:

14:37:52,625 [MKVxjThread] ERROR MKVxj.AppTemplate - Application
initialise caused exception, error: null, application will now exit..
java.lang.NullPointerException

I'm using Orbix 6.1 on Linux.

Has anyone seen this before? Or have any ideas of where/how I could
find out more about why the exception is occurring?

Thanks all,

Perhaps I also ought to add that if I get a vanilla ORB, i.e.
ORB.init() I see no exceptions. But when calling ORB.init(args, prop)
where args is null and prop contains the properties (including domain
dirs etc) it fails.

Thanks,

I've not seen it before but a thought occurs (you may have tried this
already). How about passing an empty vector instead of null? Hopefully
that would make the problem go away.

It sounds like a configuration problem. Can you make sure you have
sourced your Orbix 6.1 domain environment script (this would have been
created by the itconfigure utility when you first created your
domain). If you run 'set | grep IT' you should see some IT_
environment variables.

Hope this helps,

Have you tried passing null for prop parameter?
Please post the properties that cause NPE.
