Hello, and thank you for youre time,
I have a problem with my jsp application, when i try to get the values from the html form on the jsp page process.jsp, it sets the values of each element but then does not return them to the java page. It keeps checking the web page for more properties but when it reaches the bottom of the jsp page it terimates itsself and says source not found. Any help would be appriciated, Thanks
Here is the code for the process.jsp page
<%@ page import="java.util.ArrayList" %>
<%@ page import="scannerForm.DataAccess" %>
<%@ page import="java.util.Iterator" %>
