How to sign auto run application in blackberry

I've read the help of eclipse in blackberry development environment about the auto run application that 开发者_Python百科it requires signing.

From where can I get the sign to enable my application to be auto run?

I don't think you really need to sign application for autorun. But if you will need to, read:
