Your java program could be acting as a Greengrass Aware Device (GGAD) and connecting to Greengrass Core (GGC) using MQTT protocol. However, your java program will need to have a device certificate and be part of the group. An alternative is that you have a user lambda running inside your GGC and it opens a port for the external java program to connect to. The user lambda can be , for example, an HTTP server.
