Re: Servlet Exception While editing the values

Tue, 01 Apr 2008 04:05:48 -0700

The exception is the result of something in your JSP -- probably a bug in some of the embedded Java code. I would suggest:
1) wrapping the entire JSP with <% try{% > and <%} catch (Throwable t) { t.printStackTrace(); }%> to isolate the problem 


2) if that's not enough to solve it, start simplifying the JSP, until 
you figure out which portion is causing the error



You should also consider replacing all the scriptlet and runtime 
expression fragments with equivalent Struts or JSTL tags and/or moving 
logic into your action.
