B4J Question B4J Server Listen

[Declan]

I am sending a 12 byte string to my server.
Is there a very basic B4J example that will listen on a specific port?

So you are sending a string? Which instance is running on the server to receive that string? Apache, php, B4J-app?

If you run php you can use OKHttpUtils to send the string and get an answer back.

@KMatle
Yes, I am sending a String via the Sigfox network.
The Sigfox Callback sends to my server: "https://majorparallelogram1.dedicated.co.za:17178/id={device}&time={time}&key1={data}"
I can see my data arriving on the Sigfox Backend.
When I run the example in your above link on my server, I see the "Disconnected" changes to "Connected".
This tells me the Sigfox Callback is connecting to the B4J Example app running on my server.
I will have numerous devices sending data string to my server.
I am just concerned that if one device connects, no other devices will be accepted during that connection.

Try a second and third device at the same time. Should be no problem...

Eish, I haven't got the first one running :-(
