Hi all members!
I tried to connect with MySQL in GWT but i couldn't there is this
exception:
The method forName(String) is undefined for the type Class
there are my codes:
FIRST WAY:
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //there is first
driver
String jdbc_name = "jdbc:odbc:mashhur"; //there is "mashhur" in
JDBC name
Connection conn=DriverManager.getConnection(jdbc_name);
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("select * from country");
System.out.println("HI");
} catch (Exception e){
System.out.println(e.getMessage());
rs.close();
conn.close();
}
SECOND WAY:
public void connecter() {
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "jdbctutorial";
String driver = "com.mysql.jdbc.Driver"; // second driver;
String userName = "root";
String password = "root";
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url
+dbName,userName,password);
System.out.println("Connected to the database");
conn.close();
System.out.println("Disconnected from database");
} catch (Exception e) {
e.printStackTrace();
}
}
