Look to database properties in gameserver. I mean u must have property like:
JdbcDriver=com.mysql.jdbc.jdbc2.optional.MysqlDataSource
U need correct it for c3p0 pool. Maybe jdbc v2 or jdbc v1. I think second variant.
I set the right server, did not miss anything, I'll call several server here Freya H5 ertheia, only this server that will not turn on, I do not know what the error is, I've set the right database java is right now someone here can I say what error?
