Hi! all
I run phpmyadmin and I can create table without problem.
I am starting a jdbc2 server. But I have not able to connect on mysql.

I use mysql jdbc driver : mysql-connector-java-8.0.17.jar in the additionnal library folder.
B4X:
#AdditionalJar: mysql-connector-java-8.0.17
In config.properties
B4X:
#DATABASE CONFIGURATION
DriverClass=com.mysql.cj.jdbc.Driver
JdbcUrl=jdbc:mysql://localhost/routemap?characterEncoding=utf8
User=root
Password=
#Java server port
ServerPort=17178
But I don't have connection to database named "routmap"
I mistake someting?

Thanks OliverA.

It SOLVED.

In wamp server (php.ini) I change timezone from UTC to America/New_York
B4X:
date.timezone ="America/New_York"
In config.properties file, I add timezone like this
B4X:
JdbcUrl=jdbc:mysql://localhost/routemap?characterEncoding=utf8&useTimezone=true&serverTimezone=America/New_York
And boom I have connection to database
RemoteServer is running (08/09/2019 06:45:15)
Connection successful.
