B4J Question Send argument to running jar file

[darabon]

Assume you have a running jar file that is connected to Mysql and keep the connection.
I have a function (delete a record) in my jar file that deletes a user with PID.
Now, I need to send the argument to the jar file without reopening the jar file.
In Linux, We send a pulse to process
How do can I send an argument or request to process without reopening it?
Thanks

I would use UDPSocket for this. It is stateless and quite simple to implement. You can then have another program that sends the command to the main program.

What's the meaning of stateless?

TCP - server listens to incoming connections -> client connects to server -> communication is done between two sockets -> at some point the connection breaks and client needs to connect again.
There is a complex network state that needs to be managed.

UDP - server listens to incoming data -> client sends data.
No state to manage.

Like multiplayer games sending positions, etc. to players. You don't need to know the ip address of the receiver. It's like a broadcast. You may encrypt it if security is a must.
