RE: Null Pointers are another name for undefined values
Yes, we've had this same error popping up at times. It is most often in combination with MySQL. We got our hosting party to UNCHECK the 'maintain connections across client requests'. We then got a new error from time to time, namely that user 'dbuser' has exceeded the 'max_user_connections' resource (current value = 1). No idea where to look for this error, but at least it solved the Nullpointer exceptions errors. Maybe also our recent upgrade to the latest update of CF8 also has helped some.

Null Pointers are another name for undefined values
I have a friend who came to me a while ago with a site that wanted to change hosts and have a new look and feel. He would handle the look and feel and I'd take care of the backend. Originally he wanted to rewrite from CF to ASP, but I told him keep it CF and I can do it a lot faster and cheaper. That sold him. Unfortunately, his client pre-paid for 3 years of hosting at Network Solutions and is insisting on using their Coldfusion hosting. Even though I used to work for a hosting company that has really good CF hosting, cheaper than NSI, they're sold on the reliability of the big boys. Ugh - fine. Convert existing db from MySQL to Access, convert all SQL to be compatible, test locally and it works like a charm. Upload a test Application.cfc and index.cfm file to NSI (it took NSI 7 days to add a DSN for me) and immediately get an error as follows: The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code. Null Pointers are another name for undefined values. I've trimmed the Application.cfc file down to just: cfcomponent cfscript this.name = ihatenetworksolutions; this.applicationTimeout = createTimeSpan(1,0,0,0); this.sessionTimeout = createTimeSpan(0,0,20,0); this.sessionmanagement = yes; this.setClientCookies = yes; this.setDomainCookies = no; /cfscript cffunction name=onApplicationStart returntype=boolean output=false cfreturn this/ /cffunction cffunction name=onApplicationEnd returntype=void output=false cfargument name=applicationScope required=true /cffunction /cfcomponent If I don't upload an index.cfm file, I get a Directory Listing Denied error. As soon as I upload an index.cfm file - even just a hello world one, I get that null pointer error. I'm assuming their NSI's support will be useless if it took them a week to set a DSN. Some googling on this error took me to several forums where there error is there, but there seems to be a just a lot of ideas as to the cause (broke JVM), and no real concrete solutions. ~| Want to reach the ColdFusion community with something they want?

Re: Null Pointers are another name for undefined values
Can you upload just a hello world index.cfm without an Application.cfc (or Application.cfm)? Just curious as to whether or not the issue is definitely in the Application.cfc.

Re: Null Pointers are another name for undefined values
Yes - removing the application.cfc file and just putting up a simple index.cfm file works fine. I have literally stripped everything out of the application.cfc file and except for onApplicationStart and onApplicationEnd. I also changed the cfscriptthis.name=myapp/cfscript to cfset THIS.name = myapp/ and still getting that error. I've also loaded this application.cfc onto a CFMX7 server that I administer and it works fine there (development environment is CF8 as that's where I was anticipating hosting them until they insisted on NSI).

Re: Null Pointers are another name for undefined values
... and you're sure that the hosting environment is CF7? does an Application.cfm work? can you dump the server scope to verify the CF version?

Application.cfm DOES work.

Re: Null Pointers are another name for undefined values
Not a clue... but I'm wondering if it has anything to do with restrictions enforced by NSI. Can you manually instantiate any other CFCs?

Re: Null Pointers are another name for undefined values
Nope. Both CreateObject and cfinvoke both throw the same null pointer errors. Dammit! I can hear it now I KNEW we should have just rewritten it from scratch in ASP - which is EXACTLY what they're going to say even though the site ran fine for years on the old host (that was charging them $200 / mo. for shared hosting), and at my host (which would be $200 / yr for CF8 + MySQL on a low volume shared server).

Re: Null Pointers are another name for undefined values
Might want to ping NSI and see if they can do anything for you. I had a shared host once that disabled createObject() by default, but upon request they would enable it for whatever sandbox your site is in.
