A fix for the error: ColdFusion was unable to create an image from the specified source file

How to solve a problem that may not be obvious: the CFML image tags and functions that accept a URL won’t follow a redirect, but instead fail with this cryptic error.

ColdFusion now supports Java 12, which is already EOL. Should you use it? Java 13? 11?

Even though Adobe just added support for Java 12 to CF2018 and CF2016, I will propose you should not use that, but instead should use the latest version of Java 11. Read on for more.

Beware that Adobe forum content created between Aug 22 and Sep 12 will be LOST

Wow, I just noticed some news today, Sep 3, which–to me–is tragic. (This is about the CF Forums, though, not this CF portal where you are reading this.) If you visit the front page of any of the Adobe CF forums or subforums (like for CF Administration), as well as several other non-ColdFusion Adobe forums, you will see a message stating that: We are excited to announce we will be delivering a modern community experience to you in the very near […]

Filing issues for things like ColdFusion docs, Docker images, PMT, CFFiddle, and even the bug tracker itself

Did you know you can file bug reports or feature requests not only against CF or CFBuilder, but also for things related to CF like the CF docs, the CF2018 PMT, the CF Docker images, the API Manager, the CFFiddle.org site, and even Tracker itself? Read on.

Note: you only need to apply the latest of many CF updates

If you see multiple available updates in the CF Admin “server updates” UI, you need only apply the latest (if it’s what you want). You can “skip” the others, though note that you should study their technotes for what they added.

When you may need to refreshwsdl for calls to web services

Have you ever found that calls to web services from CF suddenly fail? when nothing has changed on your end? (No change of your CF version, no change of CF admin settings, nor any change regarding SSL/TLS on the host–all of which can cause their own problems.) What may have happened is that the owner of the web service may have changed something about their definition of that web service (in terms of methods or properties or return types). And […]

Solving problems calling out of CF via https, by updating JVM

If you’re getting errors in calling out to https urls from CF, especially if it was working and now is not, you may NOT need to import a certificate, nor modify any jvm args. You may simply need to update the JVM that CF uses, as discussed in this post.
