![]() ![]() Put the below dialog code in GUITest.java file, compile and execute it. Let's have a simple GUI java code built ( =false is already included in $JAVA_OPTS environment variable - you can also provide the switch in command line if you wish). You may also choose to replace Xvfb/x11vnc tandem with Xvnc (frame buffer + VNC server in one). You may later run x11vnc and connect it with Xvfb this way allowing for remote connection to the display with VNC protocol. ![]() ![]() If your code just requires graphical buffer then usual approach is to install Xvfb server (frame buffer emulator) then export DISPLAY=:0 and append =false to $JAVA_OPTS. Generating text-only output from a Java server or application is faster and uses less resources so it is preferred in general. We inform JVM about it with =true in $JAVA_OPTS environment variable or in Java command line. Read on.īy default there is no graphical display device support on VPSes. Java GUI can easily be used on a headless server via Xvnc or Xvfb and x11vnc. Published on in Dedicated Server Java VPS ![]()
