Hi All,
I am getting this exception when i am trying to
run a simple java program from command line.

The database i am using Oracle8i Enterprise Edition.
Here is my source code.
import java.sql.*;
public class TestJdbc
{
public static void main (String[] args)
{
TestJdbc t1 = new TestJdbc();
if (args.length <= 0)
{
return;
}
int id = new Integer(args[0]).intValue();
String fname = args[1];
String lname = args[2];
System.out.println("rows inserted = " +
t1.putData(id, fname,lname));
}
public int putData(int id,
String fname,
String lname)
{
String url= "jdbc racle:thin:@naga";
String driver =
"oracle.jdbc.driver.OracleDriver";
int rowsInserted = 0;
Connection con = null;
try
{
Class.forName(driver);
con = DriverManager.getConnection
(url,"SYSTEM","MANAGER");
String sql = "INSERT INTO Emp
(id,fname,lname)
VALUES(?,?,?)";
PreparedStatement pstmt =
con.prepareStatement(sql);
pstmt.setInt(1,id);
pstmt.setString(2,fname);
pstmt.setString(3,lname);
rowsInserted = pstmt.executeUpdate();
}
catch (ClassNotFoundException e)
{
System.out.println("The Exception
is . " + e.getMessage());
}
catch (SQLException e)
{
System.out.println("The SQL
Exception is . " + e.toString());
}
catch (Exception e)
{
System.out.println("The Exception
is . " + e.toString());
}
return rowsInserted;
}
}
Any suggestions I am rattling with this issue for the last couple of hours.
Thanks,
Addanki

Which line of code is throwing the exception?
If it is the connection, then it may be your Connection URL:
you are missing the Oracle instance name and the port that instance is listening( make sure Oracle is listening at this port too! ).
Proper URL Format:

your code only specifies the server.
