JDBC / MySQL
Here is my Java code:
Code:
import java.io.*;
import java.sql.*;
import java.util.*;
public class MySQL {
public static void main(String[] args) {
// The call to Class.forName explicitly loads the driver class
Class.forName("org.gjt.mm.mysql.Driver");
// the following url says that the protocol is jdbc, the
// subprotocol is mysql, and our database (thebookdemo) is installed on the machine
// anvil
String url = "jdbc:mysql://dnetv/darrendn";
// the method DriverManager.getConnection is the only method that a
// general programmer needs to use directly. This method establishes a
// connection to a database specified by a URL, loginID and password.
Connection con = DriverManager.getConnection(url, "root", "rajanator");
// Once a connection has been established we can create an instance
// of Statement, through which we will send queries to the database.
Statement stmt = con.createStatement();
// The method executeQuery executes a query on the database. The
// return result is of type ResultSet which is one or more rows in
// this case.
ResultSet rs = stmt.executeQuery("SELECT name FROM graffiti_wall");
}
}
even with simple code i get lots of errors! when I run it.
Code:
Exeption in thread "main" java.lang.Error: Unresolved compilation problem: out cannot be resolved
at sun.reflect.NativeConstructorAccessorImple.newInstance0(Native Method)
at sun.rat sun.reflect.NativeConstructorAccessorImple.newInstance(NativeConstrucotrImpl.java:39)
at sun.reflect.DelegatingConstructorAccessorImpl.newInstance0(DelegatingConstructorAccessorImpl.java:27 )
at java.lang.reflect.COnstructor.inewInstance(Constructor.java:274)
at MySQL.main(MySQL.java:35)
Does anyone have any idea what this cryptic error msg means?
I do PHP and MySQL development, so this java stuff is quite new to me.
Thanks in advance.
