Do use this guide Troubleshooting - Common Errors to troubleshoot your issue. The joget log files are in "[JogetRootFolder]\apache-tomcat-8.5.65\logs".

Thanks Matthew,

Here is the log and it seems Error on initializing WebApplicationContext.

INFO 22 Jul 2021 16:23:22 org.joget.commons.util.SetupManager - Using base directory: ./wflow/

This is a new installation and nothing have been configure yet

The "Error initializing WebApplicationContext" error means that Joget could not connect to your database as defined in the ".\wflow\app_datasource-default.properties". It could also be caused by insufficient database user permission. With the correct database user permissions, Joget will have the full privileges to automatically create the system tables it needs to run Joget. Read Custom Database Configuration 

Thanks Matthew.

As i mention, this is a new installation and nothing have been configure include the database. According to the user installation guide, after download the installation file and install the application. MariaDB should be installed together as well. Nothing have been prompt to me during the installation stage.

Do you able to advise what step i have miss or i need to change the configuration of the DB connection?

You need to look into the log file for the answer. Then compare the error to the list in Troubleshooting - Common Errors. Or delete the Joget folder and try reinstalling everything again. Ensure no other Apache Tomcat is running on port 8080. Cheers.
