I was wondering if it's possible to send commands from a website to a java program being ran on a computer.
Basically what I'm doing is creating a robot, but I want control over it when I'm away from my computer. So what I was thinking, was that if I could send it commands (Like 'Stop' or 'Start') from a website, I could use my smartphone to control it.
If you know a way that might work or another method that's similar please let me know, thanks!
What I've done in the past is built the Java robot into a Java EE webapp, then deployed the webapp on Tomcat. Tomcat is a Java-based web server. It's a web server, but there's also no reason you can't run arbitrary code inside it, like a robot.
Another alternative is to embed a web server into the robot, and have the robot serve up pages itself. An example of an embedded HTTP server is JETTY.
Using the above two approaches, the web pages and Robot can communicate with each other directly through Java code. It's a single process and a single JVM running both.
A third alternative is to connect the Java robot process with the web server process via sockets or another form of IPC. This could be tricky, but decouples nicely.
I was wondering if it's possible to send commands from a website to a java program being ran on a computer.
This equivalent to asking if 2 programs can communicate via network.
The answer is yes. It is obvious, right? I mean how do you connect to your website in the first place? Eh?
