No, there is probably and uncaught exception in your code. Instead of my
previous post - you can change:
> } catch( Exception e )
TO
> } catch( Throwable e )
NullPointerExceptions and other exceptions are not caught by Exception
but they are caught by Throwable, which is the lowest level.
Failing that - do wrap the entire page in the snippet I provided. If the
snippet you provided was the ENTIRE page - then my wrapping the entire
page suggestion is useless. (I am not accustomed to very short JSP pages)
