ERROR org.joget.commons.util.DynamicDataSourceManager - java.io.FileNotFoundException: .\wflow\app_datasource.properties (The system cannot find the file specified)

Reason: The .\wflow\app_datasource.properties file is missing but Joget will present option on browser screen to connect to a database and build the tables.

org.joget.commons.spring.web.CustomContextLoaderListener - ===== Error initializing WebApplicationContext ===== SEVERE [localhost-startStop-1] org.apache.tomcat.jdbc.pool.ConnectionPool.init Unable to create initial connections of pool. java.sql.SQLNonTransientConnectionException: Could not connect to address=(host=localhost)(port=3307)(type=master) : Connection refused: connect

Reason: Joget could not connect to the database, either the database is not running or the datasource values (db name, port, username, password) are wrong in .\wflow\app_datasource*.properties.

SEVERE [localhost-startStop-1] org.apache.tomcat.jdbc.pool.ConnectionPool.init Unable to create initial connections of pool. java.sql.SQLSyntaxErrorException: Could not connect: Access denied for user ''@'localhost' to database 'jwdb'

Reason: The database username is likely wrong.

SEVERE [localhost-startStop-1] org.apache.tomcat.jdbc.pool.ConnectionPool.init Unable to create initial connections of pool. java.sql.SQLInvalidAuthorizationSpecException: Could not connect: Access denied for user 'root'@'localhost' (using password: YES)

ERROR org.joget.commons.util.DynamicDataSourceManager - java.io.FileNotFoundException: C:\Users\Andrew\wflow\app_datasource.properties (The system cannot find the path specified) java.io.FileNotFoundException: C:\Users\Andrew\wflow\app_datasource.properties (The system cannot find the path specified)

Reason: The "joget-start.bat" file is missing the "set JAVA_OPTS=-Xmx512M -Dwflow.home=./wflow/ -javaagent:./wflow/aspectjweaver-1.8.5.jar" line. The missing "Dwflow.home=./wflow/" parameter will also cause Joget to think that the database datasource is missing and will present you with the setup database screen.

ERROR org.joget.commons.util.DynamicDataSourceManager - java.io.FileNotFoundException: .\wflowxx\app_datasource.properties (The system cannot find the path specified)

Reason: The "joget-start.bat" file has an incorrect "set JAVA_OPTS=-Dwflow.home=./wflow/" folder name or the folder does not exist or the folder has no read write permission.
