But if placed to /jdk root - the same, not found. Any help ?

If you are using the Ubuntu Desktop, just drag out the folder using Archiver. Here is what I have in my Ubuntu 20.04.3 guess in Virtualbox. ~$ /home/aeric/jdk-11.0.1/bin/java -version yields: openjdk version "11.0.1" 2018-10-16 OpenJDK Runtime Environment 18.9 (build 11.0.1+13) OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode) Upvote 0

peacemaker Expert Licensed User Longtime User Oct 8, 2021 #10 I had to "apt install" Openjdk, to fix the possibility to work (again 11.0.11 was installed). Now the Bridge is OK, but only if to start it by "our Java 11.0.1" in unpacked folder. App is beginning to run under Linux from Win10 B4J PC (and i still do not know how to start my app Release on Linux manually). Thank you, @aeric, for help ! Now solving error of the dll lib: B4X: Copy Caused by: java.lang.UnsatisfiedLinkError: no b4jcv_344_01 in java.library.path: [/usr/java/packages/lib, /usr/lib64, /lib64, /lib, /usr/lib] Upvote 0

Do you want to run B4J UI or non-UI app? Non-UI -> just copy the Release jar to a directory and call the jar using java -jar myapp.jar or using nohup command and output a log UI -> You need to copy the Release jar and create a new/modify the packager.json file with path to the jar file then use B4JPackager11 to re-compile the jar and create some dependencies files. Once done, execute the run.command script. Upvote 0

R rspitzer Active Member Oct 8, 2021 #12 I had a similar problem, denoted by your first screen post. The issue is when the bridge is invoked, it needs to know where the JFX files reside. You need to set your PATH_TO_FX so the program will find the JFX files. When you turn on the terminal, it opens a bash script, it is called .bashrc, at the end of this file I placed both the JAVA_HOME and PATH_TO_FX - (Below are examples using paths on my system, yours will probably be different) export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-arm64/bin export PATH_TO_FX=/usr/lib/jvm/java-11-openjdk-arm64/javafx/lib Upvote 0
