Re: Problems getting the calculator-distributed sample to work

Hi Simon,
I see exactly the same thing for ant runDomain.

However when I visit
http://localhost:9990/node-config/NodeB

I get a Null pointer exception,

java.lang.NullPointerException

Also from the UI when I click the composites tab, it shows
"Problem: Composite not found"
for all the Nodes.

Maybe thats whats causing it to fail.

Thanks,
