ADK sample error

Hi Everyone,
I am running imdkSample, and I can successfully create alias and connection pool to Oracle9i database, and create insert transaction, and generate services.
But when I run the service from Developer and got the error message below.
Thanks!

Could not run the service ‘GenerateInsert1’.
