How to send and receive an image from J2ME to a Java Web Service

Question

I've been spending the last 2-3 months trying to get this working. I'll try to be clear to what i want, i hope someone can help.

1. I have the image in an Image object in J2ME
2. I want to send the image to a Web Service
3. The Web Service is ONLY java code, i don't have access to the wsdl file. I'm writting the code in NetBeans, and i use TomCat.
4. I don't want to use anything else, like a servlet.
5. A complete example with the client and server code would be perfect :)
6. I don't want links to other sites unless they respect the 5 points above
7. I'll owe you my life if you can help me :D

PS: I already used Base64 to send the pixel data, but it's slow and i'm having problems when retrieving the image.

Thanks, Alex.
