Can someone help me identifying the error in following code. Its giving me some wierd error I dont understand that.

import java.sql.*;  
import java.sql.Types.*;

class CallProc
{

public static void main(String [] args)
  {
    try
    {
    Class.forName("oracle.jdbc.OracleDriver");
    Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "scott", "tiger");
                                                                                                   
    CallableStatement cal= con.prepareCall("{call getEmp( ? ? ?)}");

cal.setInt(1,Integer.parseInt(args[0]));
     cal.registerOutParameter(1,Types.INTEGER);
     cal.registerOutParameter(2,Types.VARCHAR);
     cal.registerOutParameter(3,Types.INTEGER);
    ResultSet rs =  cal.executeQuery();
     System.out.println("EMP Rec for Empno:"+ rs.getString(1));
     System.out.println("Empno  EName   Sal");
    
    if(rs.next())
     System.out.println(rs.getString(1)  + rs.getString(2) +  rs.getString(3));
    else
     System.out.println("No records retrieved");
  
                                                                                              
     cal.close();
     con.close();
     }   //try
  
  catch(Exception e)
  {
  System.out.println(e.getMessage());
  }
 }  //main
}//class

Error in line one column 18. encountered . when expecting some other character. I dont understand why this error is coming. Thank you in advance

In all the examples of CallableStatement I ever saw, they had commas separating the procedure's parameters. Your code doesn't. Perhaps that's the problem.
