500 Null Error Revisited By Ben Nadel on July 14, 2006 Tags: ColdFusion I recently got a 500 Null error half way through the output of a ColdFusion page. I have rarely ever coldfusion 8 500 error seen this before. If you have read my other post about 500 null errors coldfusion 500 error iis7 in ColdFusion, it's usually an error before any data reaches the browser. But half way through the page? This is

Coldfusion Administrator 500 Error
dance, I narrowed it down to this line:#REQUEST.UDFLib.Text.ToAsciiString( .... )#This line worked on the development server, but not on the live server (where the 500 null was showing up). The problem was instantly obvious to me (as I wrote the code). The method ToAsciiString() was a new method that I had written in the Text User Defined Library (UDFLib.Text). I had uploaded the code that referenced it, but I coldfusion null date had forgotten to upload the updated UDFLib.Text file. On the live site, I was attempting to reference a function that was not there. Ordinarily, this sort of problem would throw this sort of an error:The method 'ToAsciiString' could not be found in component D:\....\Text.cfc. Check to ensure that the method is defined, and that it is spelled correctly.
The error occurred on line 40.In fact, that IS the error that get's thrown on the development server when trying to duplicate the error for research. Not sure why it gives 500 null on the live server. Maybe it has something to do with the debugging settings.

Most likely you already have 1.5 installed and ColdFusion picked it up during installation, but we do not yet support it for CF7. Like Show 0 Likes(0) Actions 2. Re: ColdFusion 500 null error cfahan Dec 20, 2006 10:50 AM (in response to hello-lawrence) The answer is easy: Go to Coldfusionmx7/lib/adminconfig.xml Change the value for runsetupwizard from true to false.

The JVM is your friend License Articles ColdFusion "null, null" errors - CFInterface another possible reason by kai on 24/12/2011 Tweet Just recently I was hunting a "null, null" error in a large ColdFusion application. It started occurring all of a sudden under decent load and it was unfortunately rather hard to reproduce. Some basics: If you're getting a "null, null" error in ColdFusion (and yes, this still does occur in ColdFusion 8 and 9 occasionally, even though there was a certain known issue in CFMX 6/6.1 that was fixed with a hotfix), that almost always points to a Null Pointer Exception somewhere in the Java application that ColdFusion is nowadays. You will also see an HTTP status code of 500 and not necessarily any log output in the ColdFusion logs. Note: double check the JRun log files, you might get some additional information from them. The reason why you're getting a "null, null" error in the first place is essentially because you'd be using a CFERROR tag or any other global error handler while your application ran into that Null Pointer Exception. This has been very well explained by Steven Erat and is also noted in an Adobe technote. The best way to find out more about the issue is to actually remove all of those and then have a look into what the error is really about. That might prove tricky if the error just happens sporadically, seems to be impossible to reproduce and "obviously" just hits you on production, never on dev/test or under any artificial load test scenarios. Doh. When our instance of the "null, null" error happened it was usually during night time and hard for us to debug and get into it. Just the other week though, the error happened during day time while I was working on-site at the client's premises and we had a chance to jump on the production system, isolated the particular CF instance from the production cluster and started digging. After switching off all the error handling we found the following error messages per occurrence of the "null, null" error: 22:41:39.039 - java.lang.NullPointerException - in {filename} : line 247 22:41:39.039 - coldfusion.util.RuntimeWrapper Exception - in {filename}: line 247 22:41:39.039 - java.lang.NullPointerException - in {filename} : line 247 That's something to work with. The application is actually a large-scale Fusebox 5.5 application therefore {filename} pointed to a FB-parsed .cfm file. So - we were looking into the mentioned lines (there were a few other versions of this NPE in different areas of the site) and they all had in common that they were calling out to CFC instances in CF's application scope (let's call that A.cfc from now on - or better: appli
