Confused: java.lang.NullPointerException CF9

[hofar...@houseoffusion.com]

Can anyone give me some pointers as to where to look for the source or
maybe the solution to this problem please?

I'm confused - I am getting java.lang.NullPointerException error on a site
on a shared server, but not getting the error on other sites on that same
server. So presumably the error is something to do with the code on that
site.

But the error isnt happening on my dev environment, so maybe it's not my
code after all.

I've looked at all the notes I can find about this and can't see anyone
with my environment who's reporting that same error so I can compare notes
- at least as far as I can tell.

Our setup is:

Windows2003
CF9: 9,0,2,282541 Enterprise
Database: MSSQLServer2005

Here's my stack trace if it helps:

Without seeing any code we're just grasping at straws. My first guess is
that you have a mapping that's not set correctly, and a call to a CFC (or
perhaps an include) is not finding its target.

Thanks Matt. I dont use mappings so that rules that out. So I'll
check all my CFC calls and see if that points me to it.

Thanks.

My confusion came because none of the googling i did led to that as the
source. It's all about drivers and server versions and JVM etc. But none
of the other sites on that same box exhibit the problem.

If anyone has any other ideas as to what I can examine I'd be grateful.

Mike,

Your confusion is understandable. A NullPointerException is a generic error
(in a way) that is too specific - or perhaps I should say "symptomatic"
instead of being "causal". It's rather like saying "the patient has a
fever". Sure it's technically correct but it doesn't give you much more than
that. Why does he have a fever? Is he in love? Does he have pneumonia?
Dyspepsia? Was he bitten by Tse tse fly? You almost always have to dig a
bit deeper to understand the source of this error. I've seen it cause by
Javacasting, Db driver errors, the cfimage tag etc.

I would look in your Application.cfc's onRequestStart event handler.

I'm thinking something with the Application.cfc, based in the stack. Maybe
posting that we can help a bit further.

Can your host take a look at the exception.log to see if any additional
errors are being logged.

One possibility in my Application.cfc onRequestStart method is
Timezone.cfc. I'm using that to convert time from UTC to my timezone.
But the timezone.cfc file I'm using is dated 2005. I seem to recall
there were changes made to the java related to time, and some people had
issues with timezone.cfc. But it's been rock solid for me and I'm using
it on lots of sites without problems.

Does anyone know if this could be the source of the problem? (Obviously
I'm going to get a new version and see if the problem goes away but I'd
rather know if there are still issues with timezone.cfc)

I'd try sticking a <cfabort> at the end of OnRequestStart to see if you
get that far and then place it in the middle, then the middle again up
or down depending on the error being there or not, rinse and repeat etc
to find what is causing the error.

Hey Kym!! I thought you were going to the beach to put your feet up and
watch the sunrise nowadays. What are you doing here??

But thanks for the suggestion. As always, giving me a sensible, workable
solution that I ought to have done myself. But too stupid to do it.

I'm only semi-retired and anyway writing code is my hobby :-)

I pack up and move north next weekend and for those folks living north
of the equator down here in Oz "moving north" means heading to the sun
and even hotter weather :-)

It looks like this problem is solved, because while it's been intermittent,
I haven't had the error for a couple of days.

So that means the problem was the timezone.cfc CFC by Paul Hastings. It's
an excellent component, but the version I had was old. It's been rock
solid for years and years, but something changed in the JVM and it gave
errors.

However the fix was easy - just download a current version and replace the
old version on the site.
The new version has updates from August 2010 and adds new methods too.

Problem apparently solved.
