Hey ,
I am working on a java program in eclipse (Window XP) where
in need to connect to remote mysql database with is installed
in linux machine (fedora 7) , and i am facing a error when java program
connect to mysql database :
import java.sql.*;

public class HelloWorld {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("Checking if Driver is registered with DriverManager.");
DatabaseMetaData dbm;
Statement sql;
ResultSet rsl;

try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException cnfe) {
System.out.println("Couldn't find the driver!");
System.out.println("Let's print a stack trace, and exit.");
cnfe.printStackTrace();
System.exit(1);
}
System.out.println("Registered and loading the driver ok, so let's make a connection.");
Connection c = null;

try {
c = DriverManager.getConnection("jdbc:mysql://192.168.1.20:3306/ZoneVAXIN",
"root", "vaxinpro");
dbm = c.getMetaData();

System.out.println("Connection to "+dbm.getDatabaseProductName()+" "+
dbm.getDatabaseProductVersion()+" "+dbm.getUserName()+" "+dbm.getDriverName()+" successful.\n");
sql = c.createStatement(); //create a statement that we can use later

String sqlText1 = "create table xml_demo (code int, text varchar(20))";
System.out.println("Executing this command: "+sqlText1+"\n");
sql.executeUpdate(sqlText1);

String sqlText = "insert into xml_demo values (700,'AVALANCHE')";
System.out.println("Executing this command: "+sqlText+"\n");
sql.executeUpdate(sqlText);


sqlText = "insert into xml_demo (text)values (1200,'rais')";
System.out.println("Executing this command twice: "+sqlText+"\n");
sql.executeUpdate(sqlText);
sqlText = "insert into xml_demo values (900,'WEBSUITE')";
System.out.println("Executing this command twice: "+sqlText+"\n");
sql.executeUpdate(sqlText);

rsl = sql.executeQuery("select * from xml_demo");
if (rsl != null)
{
while (rsl.next())
{
System.out.println("code ="+rsl.getString("code")+
"; text = "+rsl.getString("text")+"\n");
}
}
rsl.close();


} catch (SQLException se) {
System.out.println("Couldn't connect: print out a stack trace and exit.");
se.printStackTrace();
System.exit(1);
}
if (c != null)
System.out.println(" We connected to the database!");
else
System.out.println("We should never get here.");

}

}
Program output :

Checking if Driver is registered with DriverManager.
Registered and loading the driver ok, so let's make a connection.
Couldn't connect: print out a stack trace and exit.
