Barcode generation for J2me

[Melssj5]

Hi, This is a not jpct related question, but feeback says: ANYTHING THAT WONT FIT IN THE OTHER FORUMS.   


Does anybody know an API to generate barcode images from a given 13 digits number in j2me.

I have been reading with no luck.

Hello, i've had a similar task once. And my solution was not to search for apis, but to code it myself  It's not so hard, you just have to read UPC or EAN documentation, all algorhythms are described there.

I was reading but had no luck finding a good doc.  Now I downloaded a code 39 font and I am trying to get the images for each char and pass it to paint, but I am afraid it wont result. :S

Any recomended tutorial for it?

A font is a solution, i used it in j2se with success, but I haven't tried it in mobile java. And yes, i think it would be too expensive for a mobile device to store images for each char. I have a good document that describes EAN construction algorhythm at work. Besides, barcode construction algorhythms are quite similar for some groups of barcodes, so i can send this doc to you tommorow, if you need it.

Can I pass to your office so you can lend me the document? Or can you please post it!

I haven't tried it but might this do it?

check your mail, Melssj5

Hi, I checked JBars but it uses a servlet to generate the label and then just send it. Is not what I needed. I already checked the mail, and thanks a lot for that piece of code, I will use it later becausse the project is delayed by the customer so the emergency passed.

Not so! You can download and examine the sourcecode which gives you;

public static synchronized Image createImage (String codeType, String codeValue)
