However, when trying to access it through Tomcat 7, it fails with error: No suitable driver found for jdbc:mysql://localhost/dbname. I am using pooling. I put in mysql connector (5.1.15), dbcp (1.4) , and pool(1.4.5) libraries in WEB-INF/lib and in .classpath as well. I am using Eclipse IDE. My code for the database driver is: import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; import org.apache.tomcat.dbcp.dbcp.ConnectionFactory; import org.apache.tomcat.dbcp.dbcp.DriverManagerConnectionFactory; import org.apache.tomcat.dbcp.dbcp.PoolableConnectionFactory; import org.apache.tomcat.dbcp.dbcp.PoolingDriver; import org.apache.tomcat.dbcp.pool.impl.GenericObjectPool; public class DatabaseConnector { public static String DB_URI = "jdbc:mysql://localhost/dbname"; public static String DB_USER = "test"; public static String DB_PASS = "password"; // Singleton instance protected static DatabaseConnector _instance; protected String _uri; protected String _username; protected String _password; /** * Singleton, so no public constructor */ protected DatabaseConnector(String uri, String username, String password) { _uri = uri; _username = username; _password = password; GenericObjectPool connectionPool = new GenericObjectPool(null); ConnectionFactory connectionFactory = new DriverManagerConnectionFactory( _uri, _username, _password); PoolableConnectionFactory poolableConnectionFactory = new Poolable

This error comes when you are trying to connect to MySQL database from Java program using JDBC but either the JDBC driver for MySQL http://www.java67.com/2016/06/javasqlsqlexception-no-suitable-driver-found-jdbc-mysql-localhost-3306.html is not available in the classpath or it is not registered prior to calling the DriverManager.getConnection() method. In order to get the connection to the database, you must first register the driver using Class.forName() method. You should call this method with the correct the name of the JDBC driver "com.mysql.jdbc.Driver" and this will both load and no suitable register the driver with JDBC. The type 4 JDBC driverfor MySQL is bundled into MySQL connector JAR e.g. mysql-connector-java-5.1.18-bin.jar depending upon which version of MySQL database you are connecting. Make sure this JAR is available in classpath before running your Java program, otherwise Class.forName() will not be able to find and load the class and throw java.lang.ClassNotFoundException: no suitable driver com.mysql.jdbc.Driver, another dreaded JDBC error, which we have seen in the earlier post. Recently I have seen a common pattern of this error where a Java developer running his program Java SE 6 expects that JDBC driver's JAR will be automatically loaded by JVM because of autoloading of JDBC driver feature of JDBC 4.0 released in JDK 6 but misses the trick that the JDBC driver should also be JDBC 4.0 compliant e.g.mysql-connector-java-5.1.18-bin.jar will be automatically loaded but older version may not, even if you run on Java 6. See Core Java Volume 2 - Advanced Features to learn more about JDBC 4.0 features. So, make sure you have both JDK 6 and a JDBC 4.0 compliant driver to leverage the auto-loading feature of JDBC 4.0 specification. How to reproduce "No suitable driver found for 'jdbc:mysql://localhost:3306/" In order to better understand this error, let's first reproduce this error by executing following Java program. I expect this program to throw the"No suitable driver found for 'jdbc:mysql://localhost:3306/" error because
