I need to add some fields and a namespace to an existing RSS feed built in ROME. A rather simple operation in theory, but I'm struggling. I figured all I'd have to do is extend SyndEntry/SyndEntryImpl and SyndFeed/SyndFeedImpl, putting the new fields in those new classes/interfaces. But apparently not?
This is a legacy application and it only does generation not consuming.
Define a custom module for you namespace, see this tutorial or this old answer: How to create entries with image element in the RSS Feed using the java ROME API?
