问题
I am using CentOS as Operating System, Mariadb as Database Server, and apache tomcat 8.5.xx as a web Server.
the Code of the Resource in Server.xml is as the following:
<Resource name="jdbc/HasanDB" auth="Container" type="javax.sql.DataSource"
maxTotal="50" maxIdle="15" minIdle="5" initialSize="2" maxWaitMillis="10000"
removeAbondend="true" removeAbondendTimeout="300"
validationQuery="select 1" testWhileIdle="true" timeBetweenEvictionRunsMillis="60000"
username="hasan" password="hasanpass" driverClassName="org.mariadb.jdbc.Driver"
url="jdbc:mariadb://localhost:3306/HasanDB"/>
I tried to connect using normal MySQL Driver but I get Access denied error for user hasan. I and when I try to connect using mariadbdriver, I get the following error in the logfile:
