Try opening a socket, or use the JavaMail API and try to connect it to J2ME.However, you don't really activate hardware within Java, you create a network or device object and Java connects that to the native implementation and hands off to the OS which then drives the hardware.

so it means that Java Mail is also applicable in J2ME? and is there a possibility to filter the messages that u wil download to text only? thanks!
