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 connectionFactor

You actually forgot the JDBC driver specific URI prefix. For the MySQL JDBC driver this is jdbc:mysql://. The full connection URL should look like this: con = DriverManager.getConnection("jdbc:mysql://localhost/test", user, pass);
suitable driver found for jdbc:mysql://localhost:3306/test The error "java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test" occurs when you try to connect MySQL database running on your localhost, listening http://javarevisited.blogspot.com/2016/09/javasqlsqlexception-no-suitable-driver-mysql-jdbc-localhost.html on port 3306 port from Java program but either you don't have https://coderanch.com/t/599127/JDBC/databases/suitable-driver-jdbc-mysql-localhost MySQL JDBC driver in your classpath or driver is not registered before calling the getConnection() method. Since JDBC API is part of JDK itself, when you write a Java program to connect any database like MySQL, SQL Server or Oracle, everything compiles fine, as you only use classes from no suitable JDK but at runtime, when the JDBC driver which is required to connect to database is not available, JDBC API either throws this error or "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver". Most common reason of this error is missing MySQL JDBC Driver JAR e.g. mysql-connector-java-5.0.8.jar not available in classpath. Another common reason is you are not registering the driver before calling the getConnection() and no suitable driver you are running on Java version lower than 6 and not using a JDBC 4.0 compliant driver. We'll see these reasons in more detail in this article. JAR not available in Classpath If mysql-connector-java-5.0.8.jar is not available in classpath then you cannot connect to MySQL database from Java. Your program like below will compile fine but as soon as you will run it you will get the error "java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test" because of the JDBC URL format "jdbc:mysql" is not matching with any registered JDBC driver. Here is our Java program to demonstrate this error. This program reproduce this error by first leaving out the required JDBC JAR from classpath and also not explicitly registering the driver before use by not calling Class.forName() method. import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; import java.util.Properties; /* * Java Program to to connect to MySQL database and * fix java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306 * error which occur if JAR is missing or you fail to register driver. */ public class Main { public static void main(String[] args)

I seem to be having trouble with java finding the Connector/j Driver. I'm getting the following error message: "No suitable driver found for jdbc:mysql:3306//localhost/test". I've made sure the mysql-connector-java-5.1.22-bin.jar file is in the classpath on my laptop as well as in the Eclipse IDE, but I still have this error. Could you point me in the right dirrection? Keep in mind this not for a webserver, just a stand alone Java swing application. Here's a sample of my connection code: public Connection getDatabaseConnection() throws SQLException { String userName = "root"; String passWord = "apple04"; Connection conn = null; Properties connectionProps = new Properties(); connectionProps.put("user", userName); connectionProps.put("password", passWord); conn = DriverManager.getConnection("jdbc:mysql:3306//localhost/test", connectionProps); return conn; } Any advice at this point would be greatly appreciated. Nam Ha Minh Ranch Hand Posts: 506 I like... posted 3 years ago The database URL is incorrect: jdbc:mysql:3306//localhost/test" It should be: jdbc:mysql//localhost:3306/test See detailed explanation here.

Waldemar Macijewski Ranch Hand Posts: 32 posted 3 years ago In Eclipse, you can add various libraries to your project in Build Path panel. In Package explorer right click on your project's name, Buildpath->Configure Build Path->Libraries->Add external jars. Point this to driver's .jar file. Joe McTigue Ranch Hand Posts: 66 posted 3 years ago Hi Mark, thanks for the advice, but already did this using eclipse and still getting the same error. :-( Here's what I've done so far: 1.) installed java SDK 7 2.) installed Connector/j 5.1 3.) installed Eclipse Juno IDE
