Naturally as Murphy's law states, our main guy left and I am still pretty new with CF as the sys admin, and we are looking to upgrade our servers. So on my development box, I have CF8 loaded, pages were working, and on an update, not sure as I don't think it was an apache one I am getting the following 500 error on the page;

java.lang.NullPointerException
at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:283)
at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543)
at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203)
at jrunx.scheduler.ThreadPool$DownstreamMetrics.invokeRunnable(ThreadPool.java:320)

at jrunx.scheduler.ThreadPool$UpstreamMetrics.invokeRunnable(ThreadPool.java:266)
at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)

Nothing in the apache logs, but the cfserver log shows the following;
Server coldfusion ready (startup time: 7 seconds)
java.lang.NullPointerException
at coldfusion.CfmServlet.init(CfmServlet.java:74)

[1]java.lang.NullPointerException

I am not sure if that helps, if not let me know what to post and I will as well.

thanks for any/all suggestions.

    xkaliburx, I would recommend you look at other logs, not just the server.log (and I assume you meant that, not cfserver.log). Besides others in the [cf]\logs\ directory, see also those in the [cf]\runtime\logs (or [jrun4]\logs, if using the multiserver/multiple instance mode of CF deployment.

    Often those other logs have much more info on what's gone wrong. I don't recognize anything from what you've offered, though perhaps someone else here may.
