Hello everyone. I am trying to make my first database connection to a mysql database with Java. I am using jdk 1.5.0, MySQL 4.1.11 nt, and I think I have the freshly downloaded driver C:\jdk1.5.0\jre\lib\ext\mysql-connector-java-3.0.16-ga-bin.jar" installed in the right spot. When I try to run the following code...
package dbfinder;
import java.sql.*;
import javax.sql.*;
import com.sun.rowset.JdbcRowSetImpl;
import javax.sql.rowset.JdbcRowSet;
import java.sql.ResultSetMetaData;
/**

public class DatabaseConnector {
public DatabaseConnector() {
}
public static void main(String args[]){
Connection connection;
Statement statement;
// ResultSet resultSet;
// ResultSetMetaData metaData;
String DATABASE_DRIVER = "com.mysql.jdbc.Driver";
String DATABASE_URL = "jdbc:mysql://localhost/state_crime";
String USER = "cis695d";
String PASSWORD = "cis695d";
JdbcRowSet rowSet = new JdbcRowSetImpl();
try {
Class.forName(DATABASE_DRIVER); // load database driver
System.out.println("class loaded");
rowSet.setUrl("DATABASE_URL");
rowSet.setUsername(USER);
rowSet.setPassword(PASSWORD);
rowSet.setCommand("Select * FROM state_crime_rates");
rowSet.execute();
ResultSetMetaData metaData = rowSet.getMetaData();
int numberOfColumns;
numberOfColumns = metaData.getColumnCount();
System.out.println(numberOfColumns);
} catch(SQLException sqlException){
sqlException.printStackTrace();
System.exit(1);
}
catch(ClassNotFoundException classNotFound){
classNotFound.printStackTrace();
System.exit(1);
}
}
}
I get the following exception...
java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(DriverManager.java:545)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
at com.sun.rowset.JdbcRowSetImpl.connect(JdbcRowSetImpl.java:618)
at com.sun.rowset.JdbcRowSetImpl.prepare(JdbcRowSetImpl.java:630)
at com.sun.rowset.JdbcRowSetImpl.execute(JdbcRowSetImpl.java:526)
at dbfinder.DatabaseConnector.main(DatabaseConnector.java:44)
Does anyone have any ideas? Is it my code? Is there a different driver I should use? Any help would be greatly appreciated.
