Handler Name not opening

Hi, Im trying to connect to a mysql database, but Handler Name doesnt open any handler, I tryied to put .jar in the app\WEB-INF\lib and also in the plugin folder over Plugin menu on fess, but anyone worked.

Whats is wrong?

Thank you.

I can install csv and wiki plugin, for example, and it opens in the “Handler name”. But mysql is now showing. What can I be doing wrong?

Thank you.

Did you install the fess-ds-db plugin? MySQL is just a JDBC driver, not a plugin.

thank you. Didnt see that. Now its working fine.

Hello, can you add these questions to your document?
