Having issues with the popup calendar feature after CF11 update 12 or CF2016 update 4? There's a fix

If you're using the cfinput type="datefield" feature to popup an calendar and are finding that it's not working correctly after ColdFusion 11 update 12 or ColdFusion 2016 update 4, there's a fix for it. (This could also happen if you're moving to CF11 or 2016 for the first time and someone else fully updated it before you started testing against it.)

The issue is discussed in a CF bug entry, CF-4198570, but since I've had a couple of customers recently ask for help on it, I thought I'd bring it up in a blog post here.

TLDR: you just need to obtain a special hotfix jar file, either the one for CF11 or the one for CF2016. (If you find that just clicking the link shows you gibberish in your browser, right-click the link and save the file instead.)

Put that saved jar in the lib\updates folder for your instance(s), and restart CF, and the problem will go away.

For more on the matter, as always, see below. :-)

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.

Long-time CFer needing to find new non-CF work? You may know more than you realize

Hey CFers: if you're thinking of getting (or are being forced) out of CF, and feel you can't find work, do you feel stuck? You probably know a lot more in terms of marketable skills than you may think.

This is a follow-up to my last post, Looking for CF people, or CF work? What can you do?.

In that one, I focused mostly on helping someone who WANTS to stay in CF, or as important, those who HAVE WORK TO OFFER in CF but have a hard time finding people.

Now this is for someone on the other side of the fence, who is now out of work in CF (by choice or circumstance) and needing to find work OUTSIDE of CF, and can't wait to develop new skills.

Looking for CF people, or CF work? What can you do?

I'm often asked by clients or folks in the community about whether I know anyone who could do some CF development work (or how they can find someone), or whether I know of any jobs/gigs available (or how they can find them).

I do have a pretty standard answer, and it's not what I think most would expect to hear in reply (if they thought I could just propose some possible specific people looking/available).

Recordings for nearly a dozen recent FusionReactor webinars I've done

I've been doing a series of one-hour webinars about FusionReactor over the past several months. They've covered nearly a dozen different topics (all with live demos), with more to come, including one just last week, "Making the Most of FusionReactor's Logs".

You can learn more about that and the previous ones and find their recordings at fusion-reactor.com/webinars. I also list all the webinars below, with links to each webinar's page with its recording.

(Note that sometimes the description offered on the main webinars page is a truncated variant, but click on the session link there or my links below which take you to the recording and the full description.)

Of course you'll find future webinars on the FR webinars page as their dates are posted, and you can register for them then (all free). By attending live of course you can ask questions as we go.

Some of the webinars are geared more toward folks who've been using FR (though maybe not to its maximum potential) though I try to make even them accessible to newcomers, while others are more well-suited to newcomers. (To be clear, I don't work for the company that makes the product, but I've been a huge fan for over 10 years.)

Easily finding cached versions of a site/page when it's down or gone

Have you ever had a web site "go dark" on you? or found that a given page on a site somehow disappeared? Maybe it's only temporary (there may even be a "we're down" message, though the site or server may just fail to respond at all), or maybe the failure of the page or site will be permanent.

The good news is that there are at least two easy ways that you may well still be able to see that content you may be missing: the Google cache (to at least see the last version which Google may have cached), and the internet archive "wayback machine", which often lets you see YEARS back in the history of a page or entire site, including one that may be long-gone.

In this post I share tips (and gotchas) on using both tools.

They aren't GUARANTEED to have the page you're looking for, but I find that they do about 99% of the time I try them (and I use them a lot, because I'm often mining gold in old blog posts or articles which have gone away across many sites I have visited).

My upcoming presentations for spring/summer 2017: some on CF, some on other topics

I'm going to be speaking several times in the coming weeks and months (on several topics, some on ColdFusion and/or CFML, some on generic topics applying to any server, and one on SQL Server 2016 SP1 specifically). I thought I ought to post that fact here (I have often failed to think to do that here over the years).

I offer below first the events at which I'll be speaking, and then the preso titles and descriptions for any readers interested. (As an update, I was informed on 5/16/17 that I'd been selected to speak at NCDevCon. While it's not in "spring/summer" per the subject above, I've added it to the info below.)

Dates announced for all six remaining ColdFusion/CFML conferences, and more Adobe CF Roadshow events

Did you know there will again be 6 CF/CFML-related conferences this year? (An update: I should have said "six remaining", as there was also Muracon which happened last month. I've modified the title to be more clear.)

I had posted last month about the upcoming CF/CFML-related conferences and some other events which had BY THEN announced their dates (3 of them). I mentioned the other 3 that would typically happen, and indeed since then, those 3 have also announced their dates. And Adobe has announced still more CF Roadshow events.

So here's all the current detail on all 6 remaining CF/CFML conferences (their name, description, date, location, link, and info on call for speakers).
