FDS can't find my destination.... how to trouble shoot?

Hello,

I am using the adobe DaoFlex to generate a flex application. Seemed to go well, but when I try to run the application it throws this error as soon as it trys to "fill" the grid:

"No destination 'Employee' exists in service flex.data.DataService"

HOW DO I TROUBLE SHOOT? What Can I check?

1) I looked in the application WEB-INF/flex directory

C:\bea\user_projects\applications\theriabook\WEB-INF\flex\data-managem ent-config.xml

and the destination employee is there!
