Hi,

I have to do a j2me application under Windows CE 4.2. This application will have to generate a bar code and send it to a bluetooth printer.

I have some doubts:

Which Virtual Machine is the best choice to install under win ce 4.2? I know only the WEME of IBM. I need a JVM that supports jsr 82 (Bluetooth api).

Have I to buy a Bluetooth api? Or a api to print using a bluetooth printer?

Is there an api to generate bar code?

Should I use CDC? or CLDC?

Help,
Marcelo.

I feel your pain. WEME/j9 is kind of a pain about the fact that it has no support for JSR 82.

The quick answer, as I got a few months ago, is that it's not really possible, per se, to 'buy' a BT API to plug in to WEME. However, I believe there are some vendors who are selling modified versions of WEME or other CDC/CLDC environments that have integrated a JSR-82 compatible solution, so you might just do a search to see what you can find. (A quick google search turned up aventanaBlueTooth and avelink as promising-looking products.)

WRT generating a barcode - I imagine there has to be a way to generate the image, though I'm not, off the top of my head, coming up with any method. (I'd think you probably would want to lean towards a CDC implementation of Java ME if you're going to do this, though - I don't know, but I'd lean towards saying CLDC lacks the tools to handle this.)
 
It is sorta covered in the JavaRanch Style Guide.
