Hello I want write my own desktop sharing application in Java.
The application should have some very default features:
-
Capture screen;
-
Allow a remote connected user to click / edit fields.
I was thinking to use Java Robot class for mouse movements / key pressing.
The problem is i don’t know what screen capture strategy to use.
Should I make sequentially screen captures (on the hosting computer) every second, and send those captures with UDP via network, so that the clients can intercept the data-grams ? Isn’t this a little overkill for the network ?
What other strategies are available ? (Except trying an already existing app).
PS: If necessary I can even write native code using JNI (still that’s the last thing I planning to do).
Later edit:
After some investigation I’ve come to the conclusion of @Thorbjørn Ravn Andersen . Java is probably not the best choice for this kind of application. I can try to use JNI, but that code will cover 75%+ of my project.
I will try to find other alternatives.
Have a good long look at the Ultra VNC project on SourceForge. Great place to start.
