Configuring FusionReactor to show "real ip address" when behind a load balancer or other proxy

If your server is behind a load balancer or other sort of proxy, you may have noticed that when you view information about requests in FusionReactor, they all have the same (or nearly the same) IP address. This can be easily fixed, and I show you how in this post.

New Oracle JVM update released, July 16 2019

Just a heads-up for folks using CF, Lucee, and other Java-based apps and app servers: Oracle has released today a new JVM update, for Java 8 and 11. It's update 221 for Java 8 (1.8.0_221), and update 4 for Java 11 (11.0.4).

For some, that's all they need to know. For most, they will probably want to read on.

My 4-part webinar series, "Troubleshooting with FusionReactor", starts Jan 30

Tomorrow (Jan 30, 2019) I am beginning a planned 4-part series of new FusionReactor webinars (to add to the 13 topics I've already done, as listed at the FusionReactor Webinars page).

These all-new ones will focus on Troubleshooting with FusionReactor and are geared toward helping folks new to FR--or perhaps experienced but a bit bemused by its many features--to better understand how to use it to troubleshoot problems in your app server (CF, Lucee, or any Java server).

The parts in the new series (with links here to register directly to attend) will be:

Having issues with the popup calendar feature in CF11 or 2016? There's a fix

If you're using the cfinput type="datefield" feature to popup a calendar and are finding that it's a) not working *at all* in ColdFusion 2016 or b) it showing up but not *correctly* after ColdFusion 11 update 12 or ColdFusion 2016 update 4, there's a fix for both.

The first problem was introduced in the CF2016 installer released in Dec 2016, and any after that, where Adobe has literally removed the library used for the calendaring, but you can add it back, as I discuss below. (If you install or installed CF 2016 from the original installer in Feb 2016, you won't see this problem as it wasn't removed then.)

The second problem was introduced in those two named updates, and was fixed in the very next updates (CF11 update 13 or CF2016 update 5). And of course, this could also happen if you're moving to CF11 or 2016 for the first time, and someone else had "fully updated" those to that update level before you started testing against it.

If you'd like to know more, read on.

VisualVM failing to find plugins/updates? Solving the 503 error with an updated URL

Have you tried to update or simply see the available plugins for VisualVM (the Java monitoring tool built into the JDK), and found that it fails to respond right away (the progress bar will show "checking") and then it reports:

Unable to connect to the Java VisualVM Plugins Center because of Server returned HTTP response code: 503 for URL: http://www.oracle.com/splash/java.net/maintenance/index.html

There is a solution.

TLDR: the quick answer is to change the URL used by the tool (Tools>Plugins>Settings) to use a new URL, such as https://visualvm.github.io/uc/8u131/updates.xml.gz.


For those who'd appreciate more detail, read on.

The 100 most interesting posts on the Adobe ColdFusion blog, the past 3 years

The Adobe ColdFusion team blog often has really some interesting content, but I find that some people are either not aware of the blog or just don't keep up on it, or perhaps they have trouble finding something they saw before or maybe heard was there.

So here I present what I feel are the 100 (technically, 105) most interesting/useful posts made there over the past 3 years (2014-16), offering information about CF and CFML which should be valuable to readers for years to come.
