Subject Re: Exception Thrown in a JSP
Date Wed, 18 Jul 2007 08:16:05 GMT
Or of course you could be using a Vector ... or something else that
extends AbstractList and a call to (Iterator).next() is causing the
problem.

Too many late nights.

one of my jsps. The line number from the exception trace is 259. If this is a line number
from the underlying jsp then the line is: <%@ include file="inc/footer.jsp" %> this
is also the last line in the jsp. If, on the, other hand the line is from the resulting servlet
code the line is: out.write("channel =\"460022903\";\n"); This also makes no sense. Here's
