Here is a classic Netmite application that blinks an LED and responds to a ping (ICMP). Note the absence of public static void main in the standard sense; Netmite uses a NetmiteApp base class.
Find a Netmite CMM (Compact Microcontroller Module) on eBay or surplus sites. These are typically 40-pin DIP modules containing an Atmega128 or similar, pre-flashed with the Netmite VM. netmite
Archivists are currently working on a to run the VM on FPGA cores of classic 8-bit computers (Commodore 64, Apple II). If successful, Netmite could become the bridge between retro computing and modern Java education. Final Verdict Netmite was either 20 years too early or exactly on time for a niche that never came. It is a testament to the fact that Java is not just for servers and smartphones; it can live in a lightbulb or a vibration sensor.

Netmite didn't rely on the host OS (because often there was no OS). It implemented its own lean TCP/IP stack directly on top of the MAC/PHY layer. While it didn't support all the bells and whistles of Linux (e.g., multicast routing), it did support ARP, ICMP (Ping), TCP, and UDP flawlessly. The Rise and Fall (And Why You Still See Netmite Today) If Netmite was so good, why isn't it as famous as Java ME or Android Things?
Because Netmite lacks a hardware breakpoint unit, debugging is done via serial traces. The System.out stream is redirected to UART0. These are typically 40-pin DIP modules containing an
