Development of a Java Application for PDAs

Hi everybody,

I�m thinking of creating a version for PDAs (using Java ME) of a Java Desktop application that I have.
This java desktop application has the following features:
- uses swing
- uses a C++ DLL, through JNI calls
- uses microsoft sql server as the DBMS


I�d like to know if I can make a light version of this desktop app for a handheld device, such as a PDA. I have two questions: which device is a good choice for my purpose and which OS is the best suited (considering I�ll have to use C++ with JNI).

Thanks in advance for any help or suggestion

You could probably manage this if you can find a decent implementation of java ME for the CDC-type devices, since they are really something of a subset of Java SE.

Device-wise, I suspect most PDA's would have sufficient screen size. The issue will be finding the environment to target - you might look to IBM's WEME/j9, which I believe makes a CDC flavor...

Good luck!

Thanks, but which OS is better or this does not matter?

To be honest, I don't know that it matters, in the sense of one being easier or harder. But I would also need to put in a caveat that I've only really developed mobile code for Windows Mobile if we're talking PDA's, since that's what I have at my disposal. I would suspect that there's more penetration in the marketplace at this point by Windows-powered devices, and that might make more sense to target, but I have no facts to back that feeling up.
 
I agree. Here's the link: http://aspose.com/file-tools
