Hi all,
This is a really basic doubt that I am getting as this is the first time I am working on a DB.
Following is the error I am getting while trying to set up a JDBC in MS SQL Server 2005.
I am using windows authentication and following are the parameters:
private final String url = "jdbc:microsoft:sqlserver://";
private final String serverName= "localhost";
private final String portNumber = "1433";
private final String databaseName= "MAKHIJA\\Forecasting";
private final String userName = "MAKHIJA\\Tarun Makhija";
private final String password = "tarun123";
The error is the following.
java.sql.SQLException
: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)

The code is as follows:
package DB;
import java.*;
public class DBConnection{
private java.sql.Connection con = null;

private final String password = "tarun123";
// Informs the driver to use server a side-cursor,
// which permits more than one active statement
// on a connection.
private final String selectMethod = "cursor";
// Constructor
public DBConnection(){}
private String getConnectionUrl(){
return url+serverName+":"+portNumber+";databaseName="+databaseName+";selectMethod="+selectMethod+";";
}
private java.sql.Connection getConnection(){
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);
if(con!=null) System.out.println("Connection Successful!");
}catch(Exception e){
e.printStackTrace();
System.out.println("Error Trace in getConnection() : " + e.getMessage());
}
return con;
}
/*

*/
public void displayDbProperties(){
java.sql.DatabaseMetaData dm = null;
java.sql.ResultSet rs = null;
try{
con= this.getConnection();
if(con!=null){
dm = con.getMetaData();
System.out.println("Driver Information");
System.out.println("\tDriver Name: "+ dm.getDriverName());
System.out.println("\tDriver Version: "+ dm.getDriverVersion ());
System.out.println("\nDatabase Information ");
System.out.println("\tDatabase Name: "+ dm.getDatabaseProductName());
System.out.println("\tDatabase Version: "+ dm.getDatabaseProductVersion());
System.out.println("Avalilable Catalogs ");
rs = dm.getCatalogs();
while(rs.next()){
System.out.println("\tcatalog: "+ rs.getString(1));
}
rs.close();
rs = null;
closeConnection();
}else System.out.println("Error: No active Connection");
}catch(Exception e){
e.printStackTrace();
}
dm=null;
}
private void closeConnection(){
try{
if(con!=null)
con.close();
con=null;
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args) throws Exception
{
DBConnection myDbTest = new DBConnection();
myDbTest.displayDbProperties();
}
}
Thanks,
Looking forward to replies!
