You may also want to look at the samples that are included with the JDK (there is an autostart sample) and at the multiple forum posts and guides to this solution on the official RIM site andelsewhere.

As an aside: I see you continue your trend of not accepting answers to any questions; this will soon make it difficult to get future answers.
