Problems when trying to start the server about rcrs-server HOT 8 CLOSED

@charon-1-1
I tested running the simulator on my own computer and it does work fine. Can you please provide us further information about the environment (computer, OS, Java version, etc) where you are trying to run the simulator? Additionally, please share the log files that you can find on the logs directory, so we can help you solve the issue.

I think the problem is with the config of types.cfgwhich mentioned ../jars

Looking at the log files, the exception is related to Java. See the snippet I copied from kernel-out.log file.

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-17-openjdk-amd64/lib/libawt_xawt.so at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2393) at java.base/java.lang.Runtime.load0(Runtime.java:755) at java.base/java.lang.System.load(System.java:1953) at java.base/jdk.internal.loader.NativeLibraries.load(Native Method) at java.base/jdk.internal.loader.NativeLibraries$NativeLibraryImpl.open(NativeLibraries.java:388)

I have a similar configuration than yours. The only difference is the Ubuntu version, I am using version 20.04. But the Java and Gradle are the same. In my computer it does not cause any error.

I noticed, however, that you are probably using an older version of the simulator (v1.5) since you are launching the start.sh script from the boot directory while in the new version (v2.0) the script is launched from the scripts directory.

The older version of the simulator (v1.5) is not compatible with Java 17. You can switch back to Java 11 or you can update to the new version of the simulator. You can clone the new version of the simulator using git clone https://github.com/roborescue/rcrs-server.git.

Please let us know if the problem persists.

Thank you for your reply, actually we have tried the new server, we have tried many on Ubuntu20.04, but we ran into the same problem. It was strange that the team members could run the server successfully with the same operation in the same environment as us, but I and several other members had this problem and were bothered by it for a long time.
Here is the log file from the new server:

It seems it is something related to your environment setup.

Can you please install the OpenJDK 17 JDK as indicated below?
sudo apt install openjdk-17-jdk

You may have the headless, but not the JDK installed.

After installing, test on the new simulator since the old one is not tested with the Java 17.

Please let us know if the problem persists.

Wow, that should be the question. We reinstalled jdK17 according to your instructions and successfully started the server. Thank you very much! We have been using Ubuntu's prompts for JDK installation, which does have -headless.
Thank you again from the bottom of my heart.

Please let us know if you have any further problem.
