This bit of code is throwing an exception that does not allow me to complete the program:

exception

org.apache.jasper.JasperException: An exception occurred processing JSP page /SaleEntry1.jsp at line 39

36:     Integer.parseInt(discountString);
37: } catch(NumberFormatException nfe) {}
38: %>
39: <jsp:setProperty 
40:     name="entry" 
41:     property="discountCode"
42:     value="<%= discountCode %>" />

root cause

org.apache.jasper.JasperException: java.lang.IllegalArgumentException: argument type mismatch

I haven't researched a solution, but is there a quick fix to this aside from not using this type of code?

My guess is that the exception involves a string formatting problem where a string value is not being formatted properly before being parsed to an Integer value.
