For future reference the topic title of Help does not help you but hurt you. Use a more detailed string of words!

Your error sounds like you are using the wrong type when you are passing parameters to your database. Using a double when it is looking for an integer or an integer when it is looking for a string.

Just an idea.

In the query, you have id has a string:
String query = "SELECT * from Product WHERE id = '" + item + "'" ;

but in the result set it is an int:
int id = rs.getInt("id") ;

One of these needs to be changed.
