-------------------------------
Summary: Welcome module (RSS) feed broken in donation
Key: NETBEANS-112
URL: https://issues.apache.org/jira/browse/NETBEANS-112
Project: NetBeans
Issue Type: Bug
Components: ide - Welcome
Reporter: lbruun
Priority: Minor
Attachments: NB-2017.png

In Apache NetBeans the RSS feeds in Welcome Page no longer works. Works on
current hg main-silver and works in NB 8.2.
The problem occurs when the downloaded XML has a doctype declaration:
{code:xml}
<!DOCTYPE rss PUBLIC "-//Netscape Communications//DTD RSS 0.91//EN"
"http://my.netscape.com/publish/formats/rss-0.91.dtd";>
{code}
There used to be a "registered" DTD for this in the Welcome module but it was
removed as part of Oracle's cleanup prior to donation. This is why it works on
current hg main-silver, but not on the donated code.
See:
http://hg.netbeans.org/releases/rev/66633aaa2811
http://hg.netbeans.org/releases/rev/00ff3249694f
Because of the removal, the XML Reader will - in the absence of a registered
DTD - attempt to download the DTD from the Internet, i.e. it will attempt to
download http://my.netscape.com/publish/formats/rss-0.91.dtd, which will fail
because it redirects to {{aol.com}} and there isn't a DTD at that location.
(duh!, I'm actually surprised that {{netscape.com}} still exists and forwards
to {{aol.com}}, it's been 18 years since the acquisition !)
The RSS feed from planetnetbeans.org (right side of screenshot) doesn't have a
DOCTYPE declaration which is why it works.
