Description MackSix 2015-08-18 04:07:35 UTC
Featured Demo: Error while loading content


Product Version: NetBeans IDE 8.1 Beta (Build 201508041349)
Java: 1.8.0_51; Java HotSpot(TM) 64-Bit Server VM 25.51-b03
Runtime: Java(TM) SE Runtime Environment 1.8.0_51-b16
System: Windows 7 version 6.1 running on amd64; Cp1252; en_US (nb)

Works now.

Product Version: NetBeans IDE Dev (Build 201509170002)
Java: 1.8.0_60; Java HotSpot(TM) 64-Bit Server VM 25.60-b23
Runtime: Java(TM) SE Runtime Environment 1.8.0_60-b27

Thanks for the update. Verifying then.
Comment 3 ericjs 2016-01-06 19:47:30 UTC
Apparently broken again. I'm seeing this with

Product Version: NetBeans IDE 8.1 (Build 201510222201)
Java: 1.8.0_66; Java HotSpot(TM) 64-Bit Server VM 25.66-b17
Runtime: Java(TM) SE Runtime Environment 1.8.0_66-b17
System: Linux version 4.2.6-1-CHAKRA running on amd64; UTF-8; en_US (nb)

The "blogs" side has content, but the "News & Tutorials" is empty except for "Error while loading content"
Comment 4 ericjs 2016-01-13 16:32:55 UTC
I've seen this break several times over the few years I've used NetBeans, which suggests to me that there is something about the design or process for keeping this working that is fragile and needs addressing.

I'd also comment that it surprises me that this isn't taken more seriously. Not that it breaks "real" functionality, but it is such a high profile flaw. This is the page that is in every user's face every time they open the application (if they haven't turned it off). It's not uncommon for a person using this to be using it in a shop with other developers using, say, the more dominant Eclipse, and it is a very poor advertisement for Netbeans that something so visible is simply broken.

FWIW, still an irritating problem NB 8.1 / Windows 8.1.

I second comments by ericjs.

Both News & Tutorials and Blogs Worked for me in 8.1 but neither does in 8.2

The proxy is turned off and I can reach the pages in firefox.

The IDE log reports :

SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Line number:1
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Column number:1
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Public ID:null

Comment 7 cwhjones 2016-10-22 03:41:22 UTC
The org.netbeans.modules.welcome.content.RSSFeed error messages from the log in my earlier message seem unrelated to the failure to communicate. On reopening the UI I still get the 'Error while loading content' messages in the UI but can not see any errors in the log.
Comment 8 clartaq 2017-01-03 16:00:32 UTC
This also happened when I updated to 8.2 on Ubuntu 16.04 (64 bit).

Initially neither the "News & Tutorials" or "Blogs" pane would populate.

I added:

JAVA_OPTS=-Djava.net.preferIPv4Stack=true

to the system environment. Now the "Blogs" pane populates correctly.

The "News & Tutorials" pane still displays "Cannot connect to internet". When reviewing the proxy settings ("No proxy" in my case), pressing the "Test Connection" button results in a green checkmark, but still doesn't populate the pane.
Comment 9 clartaq 2017-01-07 15:07:04 UTC
This could be a complete red herring, but the problem disappeared on Windows 10 64-bit NB 8.2 after I deleted the "NetBeansProjects" folder from my user document directory.

Both the "News & Tutorials" pane and the "Featured Demo" pane are populating as expected.

Nothing to do with Java/Project.
