G GPN Member Licensed User Longtime User Aug 5, 2015 #1 I'm developing an UI application for Raspberry PI. I'm using B4J with the remote bridge. The application doesn't run cause of missing component on Raspberry PI. I've installed jdk-1.8.0_60 for ARM. What do I have to install on Raspberry? The same error occours when I try: sudo java - jar AsyncInput1 in tempjars. Thanks, regards.

G GPN Member Licensed User Longtime User Aug 5, 2015 #3 Thanks a lot for your reply. I've followed the steps shown at this link: http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/RaspberryPiFX/raspberryfx.html I've thought that it is the same for B4J. Why not? Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Aug 5, 2015 #4 Oracle removed support for JavaFX in the ARM distribution in version 8u33: https://jaxenter.com/jdk-arm-without-javafx-end-javafx-embedded-114212.html You can use Java 8u6. Another (better) option it to create a non-ui app. You can create a server app and access it from the browser. JavaFX apps run very slow on Raspberry Pi which makes them barely usable. Upvote 0

rwblinn Well-Known Member Licensed User Longtime User Aug 5, 2015 #8 Hi, I had a simliar dilemma. Beside a B4J Server App solution (a great B4J feature), I have developed kind of hybrid B4J apps (using Inline Java for the UI and B4J for the logic) which run pretty well on a RPi2. Look here for more info - but note, these apps have a real simple UI. For complex UIs it will take some effort. I found running JavaFX on RPi as not acceptable (very slow, full screen). Upvote 0
