Update: 3 days after this update, Adobe released yet another, and then 4 days after that they released yet another, both p1 security updates. While I have posts on each of the two subsequent updates, the one on Jul 14 and then the one on Jul 19, the information below is still important and has details that I do not repeat in the later post.

For more resources as well as some additional thoughts on the updates, read on.

What if you want it back? In this post, I explain what changed, why, and how to get the functionality back--albeit at your own risk. For more, read on.

Update Jul 2023: Before considering what I share in this post, note that if you have updated your CF to use the Java update from Jul 2023, the cause of this error may be due to a totally different issue. See my post from July 2023 on that matter.

Update Feb 2023: In mid-February 2023, Adobe did re-sign their jars and placed them on the uploads site so that either the CF Admin update download or anyone performing a manual download after that date WOULD get the newly signed jars, and the problem below then no longer happens. (They are now signed as "SHA256withRSA, 4096-bit key".) I leave the rest here still for those who would want to understand what DID happen and why the update jars that were in place then DID change (slightly) for this reason.

I've seen the problem raised often enough that when I saw someone raising it this weekend, I decided to solve it by creating a new folder in the cfmlrepo.com site, at least for CF2021 and CF2018 (for now), offering there the initial versions of all the neo-*.xml files for those two editions.

For more information, see what I shared (including more background on the issue, where I got the files, where I put the files, and more) in my reply about all this to the CF Community thread where the user raised the need this weekend.

And for the sake of those who may "just want the files" without any need of explanation or warnings:

• cfmlrepo folder of neo-*.xml files for CF2021
• cfmlrepo folder of neo-*.xml files for CF2018

I welcome thoughts, feedback, or suggestions.

• release notes for java 11.0.9
• release notes for java 8.0_271

For some, that's all they need to hear.

And I could (and probably should) leave it at that. But there are other questions which folks will have, including more on getting those binaries/installers (from Oracle or Adobe), on the difference between those LTS versions and "more recent" Java versions, as well as non-Oracle JVMs, and on licensing matters and more. For those, read on. Perhaps I will split this other stuff out into its own post at some point, so I can just point to it from news of these Java updates.

Migrating or Comparing CF Admin Settings, between instances, versions, and engines

You can learn more (including the description, the online meeting URL, where the recording will be posted, and more) at the meetup event page. FWIW, the session name had to be shortened a bit as presented on the meetup site there and even in the title here. :-)

As a bonus for you, my blog readers, I'll note that I'll be covering the CF migration and CAR features, the Commandbox CFConfig tool (which can be used for more than just "box" instances) and the CF2020 cfsetup tool (which has been shown publicly already), and more.

I'll also have a special surprise for people who "just want to compare the Admin settings of two instances without resorting to command-line tools, or hopping back and forth between browser tabs", using a free cross-platform GUI compare tool (and a simple trick in the CF Admin) which has delighted nearly everyone I've ever shown it to. And the tool can benefit you for far more than this one task. :-)

This question, "How can I keep CF Admin settings in sync between multiple servers or instances?" was asked today on the Adobe CF forums. The person had CF instances on multiple servers and lamented having to login to each CF admin to make changes that would apply equally to all instances, in particular creating or changing datasources.

They wondered if in fact there was a feature in the CF Admin to "cluster" datasource definitions, like there is (since CF2016 Enterprise) the feature to "cluster" scheduled tasks.

While I explained that there was not such a "feature" to sync CF admin settings generally across instances, I added that there WERE at least a couple of options one could consider using to achieve the goal. (And as an update after I wrote this in Apr 2020, note that CF2021 came out a few months later offering still one more.) My answer elaborating things (as is my wont) was long enough that I should have probably created a blog post instead. After submitting it, I decided to do just that, here (and I have tweaked here what I said, with some more elaboration and links).

Short answer: there are different tools that might be considered to help with this task (especially automating it), and a couple more that some may consider:

• the CFConfig tool within CommandBox, a powerful and automatable command line tool which uses json files and could allow you to sync things, even across CF versions and between CF and Lucee
• the CF2021 cfsetup tool, a new command line tool which also uses json files and could allow you to sync things, for CF2021 and even earlier version
• the CF Admin API (minimalist and manual), which you'd have to code to sync settings or set them in a synced manner
• the CF CAR file feature deserves a mention also, though its use can't be automated (it seems)
• I would advise AGAINST the seeming "shortcut" of copying neo xml files, especially between different servers or CF versions (same with using symlinks, etc.)
