    Default Insert into database from flat file

    Hi, I am trying to insert the contents of a flat file into table. To connect to database i am using JDBC driver. I the problem i am facing is the contents of flat file is being inserted into table only for the first time when i run the program, again when i try to insert into it( even though table is empty) i am getting an error message.
    Can anyone help me in this regard.
    Thanks in advance.

    program to insert into table:
     
    public void doWork (String s) throws Exception{
     
    		    String [] ar = s.split("\\-");
    		    try{
    		      Class.forName("oracle.jdbc.driver.OracleDriver");
    		      con = DriverManager.getConnection(url,userName,password);
    		      String queryString = "INSERT INTO feeds ( subject,time,creator) values('"+ar[0]+"','"+ar[1]+"','"+ar[2]+"')"; 
     
    		      stmt=con.createStatement();
    		      val = stmt.executeUpdate(queryString);
     
    		    }
    		    catch(Exception e)
    		    {
    		      System.out.println("e : " + e);
    		    }
    	  }

    Error message I am getting again when i run the program:

    e : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
    e : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
    e : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

    Are you sure you have the JDBC driver installed correctly? It doesn't look like it can find it..
