Hi,
Maybe this article can help you:
www.stambia.org/doc/57-stambia-di-softwa...iguring-jdbc-drivers

++¡SOLUTION!++

stambia show me the error message in the image below

this happens because the jar file is not in the right path

Stambia/runtime/lib

if you change your jar file into this path all going right

pd1* don't forget make again all the process of creation for the driver
pd2* don't forget restart your enviroment and your stambia designer

Hello
Did you restart the Runtime after installing Mysql's jar file into the lib/jdbc folder ?

each time I click on stop runtime and start runtime and tick off/ON the connect button.
Question: how can I restart the runtime?

Maybe the Runtime is already started as a Windows Service ? In this case, restart the Windows service.

I can have the windows service name of stambia

I was thinking of a Windows service because your Designer is connected to the Runtime "localhost:42000" but there is apparently no Console (windows command line) window in your task bar.
If someone installed the Runtime as a Service they may have specified a service name of their choice. If they did not specify the name then the default is "Stambia Runtime".

it's OK now
download the connector from the mysql site: downloads.mysql.com/archives/c-j/

put the connector at the folder StambiaRuntime / lib / jdbc

go to stambia level designer> windows> preference> SQL explorer> jdbc

search Mysql jdbc> Edit> extra path
add the connector
URL: jdbc: mysql: // localhost: 3306 / NAMEDATABASE? UseUnicode = true & useJDBCCompliantTimezoneShift = true & useLegacyDatetimeCode = false & serverTimezone = UTC

restart the runtime
