Hi,
Could you try changing the JDBC class drive name
From: com.mysql.jdbc.Driver
To: com.mysql.cj.jdbc.Driver
Recent versions of the JDBC driver use a different name for the driver
https://dev.mysql.com/doc/connector-j/8 ... anges.html
Let me know how you get on with this
Best regards
Neil

Hi,
protege does not scan for driver jars its installation directory at startup. By default, It expects these driver files to be called either driver.jar, driver1.jar, driver2.jar.
Did you rename the driver jar file when you copied it to the install dir ?
regards,
J.-M.
PS: Expected names (driverX.jar) come from a configuration line in the Protege.lax file, you may also check that this line exists in yours :
Code: Select all
lax.class.path=protege.jar:looks.jar:unicode_panel.jar:driver.jar:driver0.jar:driver1.jar:driver2.jar$:lax.jar

It's difficult to tell why the application is not starting withour error message.Just two guesses :
1) if it doesn't start *after* you just renamed your jdbc driver file to some driverX.jar' : there is a problem with this jdbc driver file;
1) in case you modified your lax file according to my previous post : I'm sorry but there is a typo in it : you should remove the '$' character :
Code: Select all
lax.class.path=protege.jar:looks.jar:unicode_panel.jar:driver.jar:driver0.jar:driver1.jar:driver2.jar:lax.jar
