Java database application with Palm

Anyone developed a business data intensive application under Palm using Java? I wondered the performance is acceptable or not. My project is going to develop PDA (most likely Palm) solution and integrate to the existing Java database application. I want to use J2ME but I am afraid the performance cannot meet our user expectation. If we use C, our team need to pick up new skill and involve higher cost. Any suggestion?

Difficult to say... if the project involves using J2EE to provide the backend work and send the data to the PDA then J2ME will be fine. If you are the project involves wrting a DB that resides on the PDA itself, then you will up against the bottlenecks that a small memory device have. A good idea might be to go to and join one of there developer discussion groups. Try

I think you can find a helpful example about a bussines data app in the link below. I did only browse it, but I guess it might answer your question:

Thanks for your reply.
Actually, the main purpose of my application is to download the product catalog and price list to the palm during hotsync and let salesman bring those information to the customer site and provide a instant reference. I would say, my application require a store and forward (through hotsync) instead of wireless application because it didn't require real time quote and wireless is much expensive.
I am also a Palm developer and C is always the best answer to Palm application. But I cannot complete the project on my own, most of my team members are already progrmaming in Java. That's why I wonder if we can rely on Java on Palm platform.

I still find the PALM API for Java rather limited (I haven't checked for updates though) so I think you'd still be better off with C with what you're planning to do.
I agree. Here's the link:
