Yes you are right, you need to do this.

Thanks for this great post. I followed your description and now my tool produces valid RSS feeds. Have a look at http://www.feederator.org. It cost me some time to figure out that I had to add the new module myself:
List modules = feed.getModules();
AtomNSModuleImpl module = new AtomNSModuleImpl();
module.setLink(req.getRequestURL().toString());
modules.add(module);
feed.setModules(modules);

Was that the intention or did I do something wrong and this step wouldn’t have been necessary?

Thanks jettro for the code. I found it usefull as an entry point to the API but imho it has some errors.

If you like, have a look at my solution: http://info.michael-simons.eu/2011/02/14/all-roads-lead-to-rome/

Have a nice day,
Michael.

I am using Rome 1.0 to generate an Atom 1.0 feed. I found I did not need to extend Rome to get a valid feed, here is the appropriate Rome API usage:

SyndFeed techFeed = new SyndFeedImpl();

feed.setUri(myFeedURI);
feed.setLink(myFeedLink);

SyndLink linkRelSelf = new SyndLinkImpl();
linkRelSelf.setHref(feedURL);
linkRelSelf.setRel(“self”);
linkRelSelf.setType(“application/rss+xml”);
feed.getLinks().add(linkRelSelf);

feed.setTitle(“your title”);
feed.setDescription(“your description”);
// use greatest entry date
feed.setPublishedDate(new Date());

… add entries …

Hi Andreea, sorry for the delay, just back from vacation. I put it in /src/java directory. I’m using NetBeans which seems to find it in that location. I also have a log4j properties file there. I should have noticed that and put the Rome file there in the first place!

Hi. I am trying to create custom modules in order to add some elements to the ROME generated feeds and feed item, and I am having the problem of ROME not finding the rome.properties file, although I have tried to place it in several paths. Any information that helped you get over this step that you can share, Bill?

Prop file is finally getting read. Breaking in generate() now and see additional namespaces being added to root.additionalNamespaces[] via addNamespaceDeclaration(). There are 6 in that array before I add mine. None of the additional namespaces appear in the XML output. Getting closer!

I do not have the source code with me. Will respond after the week-end.

Hi Jettro, thanks for the post! I’m trying to do almost exactly the same thing – add additional namespace(s) to the feed. I’ve copied your code from above and modified the URI link for a different namespace. But I must be missing some important step as when I run the code, I don’t get anything new in the output.

My rome.properties file looks like:
atom_1.0.feed.ModuleGenerator.classes=com.foo.Rome.aggregator.AtomNSModuleGenerator

and is located in:
/source/trunk/com.foo.Rome.aggregator/rome.properties (I also tried putting a copy in the folder with my jar files)

I’ve added the following to my main java file as I’d see other samples which did so:

feed.getModules().add(new AtomNSModuleImpl());

This does break at the AtomNSModuleImpl constructor, but I get no other breakpoints hit in any methods in the Impl or Generator classes.

Not surprisingly, when I generate the output, I don’t see the updated namespace.

Is there an additional call needed in the main java file? Is something wrong with the rome.properties contents/location such that it isn’t finding/calling the Generator class? Getting the Generator called seems to be the missing link.

I’m a java/unix newbie after doing Win32 for years so I am probably doing something horribly stupid, but I haven’t spotted it yet despite reading all the samples I can find. But I’ll keep banging my head against the wall cause I’m too ignorant to stop!

Any thoughts?

Cheers!
Bill
