Running ColdFusion Under a Service Account on Windows Server and Null Pointer Errors

I was installing ColdFusion 8.01 on a new Windows Server 2003 VM yesterday, and since the application that will be running on this box needs access to network shares I had our network admins create a new domain service account under which to run ColdFusion. This is pretty commonplace for a lot of our apps, but for some reason when I switched the CF service to run under the service account I started getting a 500 error with the following details when any .cfm page was hit:


 



java.lang.NullPointerExceptionat jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:285)at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543)at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203)at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:428)at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)



This was even after I had assigned "full control" rights to the service account user to the application directory.


I asked around a bit since I'd never seen this before, and Dave Watts came up with the solution. (Thanks Dave!) In this case I logged onto the server via remote desktop using the service account, at which point I was forced to change my password. After I changed my password, the remote desktop login didn't proceed because that user didn't have RDP rights on the server. I didn't think that was an issue, but Dave suggested that there might be a problem if the service account didn't have a local profile created on the server, which of course happens the first time a user logs in.

I gave the service account RDP rights, logged in as that user, the local profile was created, and everything works now. So if you see null pointer errors when trying to run CF using a service account, this might be your problem.

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Setting Up Django On a Raspberry Pi

This past weekend I finally got a chance to set up one of my two Raspberry Pis to use as a Django server so I thought I'd share the steps I went through both to save someone else attempting to do this some time as well as get any feedback in case there are different/better ways to do any of this.

I'm running this from my house (URL forthcoming once I get the real Django app finalized and put on the Raspberry Pi) using dyndns.org. I don't cover that aspect of things in this post but I'm happy to write that up as well if people are interested.
