Org.hibernate.exception.JDBCConnectionException

Я работал над проектом гибернации в eclipse. Я поместил все файлы jars, включая jar соединителя Mysql, в папку WEB-INF lib. Когда я пытаюсь запустить код, он выдает ошибку.

Исключение

org.hibernate.exception.JDBCConnectionException: Could not open connection org.hibernate.exception.internal.SQLStateConversionDelegate.convert(SQLStateConversionDelegate.java:131) org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:49) org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:125) org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:110) org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.obtainConnection(LogicalConnectionImpl.java:304) org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.getConnection(LogicalConnectionImpl.java:169) org.hibernate.engine.transaction.internal.jdbc.JdbcTransaction.doBegin(JdbcTransaction.java:67) org.hibernate.engine.transaction.spi.AbstractTransactionImpl.begin(AbstractTransactionImpl.java:160) org.hibernate.internal.SessionImpl.beginTransaction(SessionImpl.java:1363) first.doPost(first.java:37) javax.servlet.http.HttpServlet.service(HttpServlet.java:661) javax.servlet.http.HttpServlet.service(HttpServlet.java:742) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

Первопричина

java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/sample java.sql/java.sql.DriverManager.getConnection(Unknown Source) java.sql/java.sql.DriverManager.getConnection(Unknown Source) org.hibernate.service.jdbc.connections.internal.DriverManagerConnectionProviderImpl.getConnection(DriverManagerConnectionProviderImpl.java:192) org.hibernate.internal.AbstractSessionImpl$NonContextualJdbcConnectionAccess.obtainConnection(AbstractSessionImpl.java:278) org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.obtainConnection(LogicalConnectionImpl.java:297) org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.getConnection(LogicalConnectionImpl.java:169) org.hibernate.engine.transaction.internal.jdbc.JdbcTransaction.doBegin(JdbcTransaction.java:67) org.hibernate.engine.transaction.spi.AbstractTransactionImpl.begin(AbstractTransactionImpl.java:160) org.hibernate.internal.SessionImpl.beginTransaction(SessionImpl.java:1363) first.doPost(first.java:37) javax.servlet.http.HttpServlet.service(HttpServlet.java:661) javax.servlet.http.HttpServlet.service(HttpServlet.java:742) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52
