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. :-)

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.

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.

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).

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.)

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).

[Updated June 9 in a variety of ways, mostly minor, but with some additions in the "trip down memory lane" discussion.)

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.)
