Hi all, Has anyone done any programming using j2me? I believe I have got everything set up correctly using eclipse and j2me. Unfortunately, the jar file that I am producing using the "package" option is invalid that is, my Nokia E51 tells me that the jar file that I am trying to install onto it is invalid. I have not been able to get the emulator to work either. Does anyone know what I could be doing wrong? I have used the setup instructions at the following link. http://www.javamidlet.com/2008/01/18/how-to-setup-eclipse-for-mobile-java-de velopment.html the application and Britain is a simple hello world programme. I have taken the source code from the following link. http://sprintdevelopers.com/node/9 Pranav __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind
