Java Programming

Hi! I 've a code to read an excel file using JDBC-ODBC bridge. I can read the values, but any special characters is readed wrong, just symbols. The special characters are of spanish language. This is my code:

                Locale currentLocale;
		currentLocale = new Locale("es", "MX");
		Locale.setDefault(currentLocale);

			Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
			c = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=comisionesperfiles.xls");
			stmnt = c.createStatement();
			String query = "Select * from [Hoja1$]" ;
			ResultSet rs = stmnt.executeQuery( query );
			while( rs.next() ){
				String valor = rs.getString(2) ;

				if(valor != null && !"null".equalsIgnoreCase(valor)){
					if(!comisiones.contains(valor)){
						System.out.println(valor);
						comisiones.add( valor );
					}
				}
			}
			rs.close();
			stmnt.close();

As you can see, I've tried to set the locale, but it didn't work.
I'm using Excel 2003, Java Version 1.4.2_07 and Windows XP Professional (in latin american spanish).

Hope someone can help me!
