RESTful

[Kalaiyarasi Ramachandran]

Hi,

My mini project is to develop RESTful web services for corporate updated news like i google. i have to fetch data from RSS feed in differnt corpaorates web sites. i plan to use Java. Please help me how to build , what are the processes, what are the tools are required. i refered developerworks. they given details in spring framework. I used DOM parser used to fetch RSS feed into java code. i dont know how to fetch data from mulitiple rss feeds.
i don't know the clear idea. please help me.



Thank You

I'm stumped (and curious) - how does one build a "RESTful WS using RSS"? Or rather, how would it work? What does a REST WS have to do with RSS? I've never heard of that.

I'd say it largely depends on the environment where your application should run. Should it be a Java standalone application? Running inside a Servlet container? Inside an application server? OSGi container?

There are many frameworks and tools to support the implementation of REST webservices. Depending on the mentioned environments or platforms there may be out-of-the-box support for REST. For standalone applications JBoss RESTEasy or the Restlet framework may be good candidates. Many web frameworks allow to implement REST services without additional frameworks. The JEE platform has built-in support in the form of the JAX-RS API. There are more than enough tools and frameworks. I think the bigger challenge is how to design a good web API which is really RESTful.

@Ulf: It's not uncommon to use the Atom format or something like that as a media type for REST resources. I guess that's what the OP meant.

I guess you could think of an RSS feed as a read-only RESTful resource. Interesting, that had never occurred to me.

Are you sure you really need RESTful webservices for this problem? Just because you are consuming and publishing XML via HTTP doesn't mean that it is a REST architecture (and maybe you don't really need one).

To parse some XML feeds and compose other XML feeds with the aggregated content you probably don't have to worry too much about REST principles and tools. Of course a handful of RSS feeds CAN be designed with a REST API but don't make the solution more complex than it has to be. Maybe a simple HTTP client library and a Servlet container will do fine.

There is no "REST API" - REST is an architecture for strict use of HTTP methods.

Individual REST toolkits may have an API but you don't need a toolkit to make a RESTful service, just pay attention to the architectural principles.

Thanks for hint! Maybe my wording was rather unfortunate. What I really meant was that it would be possible to expose some RSS feeds as a web API which adheres to REST principles. Of course there isn't such a thing like a REST API.

Hi,
My idea is to use REST architecture when i invoke back end from front end via get,post,put methods.
