Property Description : (list bar)
Property Description : null
(submit button)
.............................................................................
As you can see from the above, i need to choose option from a list bar. after choose an option, it will automatically show at below replacing the null. when the statement is display, i can change it to replace with the more updated one. Then click submit button when property description is changed. the problem is my program can't automatically display statement when i choose option from list bar. i include some part of my code and hope to be corrected.i am using jsp
<%! String property_code, property_desc; %><% if (request.getParameter("hid_value") != null ) {
String property_code = request.getParameter("hid_value");
String property_desc = request.getParameter("property_desc");String update1 = "UPDATE fcprop SET fp_prop_desc='"+property_desc+"' "+
"WHERE fp_prop_desc = '"+property_desc+"' ";
PreparedStatement pstmt1 = conn.prepareStatement(update1);
pstmt1.executeUpdate();
pstmt1.close();response.sendRedirect("property_information.jsp");
