Issue/Introduction

WebApp will not start

Cause

Not all required Linux packages were installed. 

Troubleshooting:  

The following error is seen in the webswing.log file:

2024-10-21 16:29:06,138 ERROR [Webswing Process Handler] (SwingProcessImpl.java:217) [oneclickwebapp_anonym_90647cebdb15_1729528144506] Caused by: java.awt.AWTError: Can't connect to X11 window server using ':99' as the value of the DISPLAY variable.

When the WebApp is started, we should see the following Xvfb process running:

Xvfb :99 -screen 0 640x480x24 -nolisten tcp

In this case, we did not see this running.

We ran this from the command line, we see the following error:

/usr/bin/xkbcomp: error while loading shared libraries: libxkbfile.so.1: cannot open shared object file: No such file or directory.

Resolution

Installed  libxkbfile.so.1
