Hi tomcat experts,
I'm having this problem with the mysql connection in tomcat using netbeans.
I'm always having a exclamation mark on the Blue World Globe in netbeans
project tabs.
I don't know what that means.

change it to abc_admin and press test connection button , it managed to
connect. When I press the finished button I always get Unable to add
connection. Connection already exist
