Re: Web services and J2ME

Hi Emmanuel,

If you can deploy a servlet, it sounds like the J2ME Wireless Connection
Wizard will do what you need. It is a plug-in module for Sun ONE Studio
that generates client and server code for J2ME devices to connect to
servers. It is focussed on low client footprint and low network bandwidth.
