Hi!

Thank you for this useful plugin; could you please assist me with the
error I get?

I installed the SCTMExecutor plugin which enables integration of
Hudson and SilkCentral Test Manager (I am using SilkCentral Test
Manager 2009SP1).

When I configure an execution in Hudson as below...:

Build
SilkCentral Test Manager Execution
Execution Definition ID : 110
SCTM Project ID SCTM Project ID: 1

...and then press Save I get the following error...

HTTP Status 500 -
