Invalid Handle Exception grr.

Question

I get this every time i try to update my database. not when i read from it, that goes error free but writing to it, ug. Here's whats goin on:
the setup for the table is:
Verb Type
String Integer
Con is the Connection that is always successful when used to read data
the Method FindData returns "Yes" if the verb exists in the table and "No" if it doesn't and yes i have my reasons for making it return a string instead of a boolean
Command is a Statement: Statement Command = Con.createStatement();
Update is a String
i is an int
if (FindData(Con, Verb).compareTo("No") == 0)
     Update = "insert into [Sheet1$] (Verb, Type) values('"+Verb+"', "+Integer.parseInt(Data)+")";
     System.out.println("Update: "+Update);
     i = Command.executeUpdate(Update);
     if (i == 1) System.out.println("Success!!!"); else System.out.println("Failed");
     Command.close();
     Con.close();
     System.out.println("EXISTS:: "+FindData(Con, Verb));                    
here's what i get as output:
----jGRASP exec: java UpdateData
Update: insert into [Sheet1$] (Verb, Type) values('Mentir', 1)
Invalid handle
----jGRASP: operation complete.
Which means it throws an exception at the i = Command.executeUpdate(Update); line and doesn't go further than that.
Does anyone know what this function even means?
Does anyone know how to fix this?
if you need more information pleas let me know
Thanks, Lateralus

Answer 1

yep it's an excel driver that allows you to connect to excel databases. here's my getConnection function:
public static Connection getConnection(String FilePath, String FileName)
     String Driver = "";
     String Url = "";
     String Username = "";
     String Password = "";
     Connection Con = null;
     try
          Driver = "sun.jdbc.odbc.JdbcOdbcDriver";
          Url = "jdbc:odbc:Excel Files;DBQ=";
          Url += FilePath+"\\"+FileName;
          Username = "";
          Password = "";
          Class.forName(Driver); // load JDBC-ODBC driver
          return DriverManager.getConnection(Url, Username, Password);
     catch (Exception e) {System.out.println("getConnection:  "+e.getMessage());}
     return(Con);
}
