Defining RSSBus Services in SharePoint

You can define and serve RSSBus Simple Services directly in SharePoint, and store them in Document Libraries. You can use these libraries as a Service Registry, and you can set SharePoint permissions on the libraries and services.

To use this feature,

• Activate the RSSBus SharePoint HTTP Handler feature.
• Install RSSBus Connectors for the data sources you plan to access. You don't need to install any connectors if you only plan to access and re-serve RSS feeds.
• Create or find your service. The best place to learn about Simple Services is the RSBScript Quick Start Guide. Services on SharePoint are very similar to services as described in the Quick Start Guide, except:
  • You must import the connector at the top of the script. For example, if your Simple Service used the sqlSelect operation from the SqlOps connector, you must include this statement at the beginning of the Simple Service definition:
    

    <rsb:import lib="RSSBus.SqlOps"/> 

  • Here is a Simple Service definition you can use for practice. It does not require you to install any connectors or use the import statement because it just calls a news feed:

    <rsb:info title="Sample News Service">
        <input name="type" values="topstories, us, world, business" default="us" />
    </rsb:info>
    
    <rsb:call op="http://rss.news.yahoo.com/rss/[type]">
        <rsb:push/>
    </rsb:call>
    

• Use a text editor such as Notepad to write your RSBScript Service. Or, copy and paste the above code into a text document.
• Save the service as a .rsb file, or save it as Plain Text (.txt) and rename the file to .rsb.
• Create a SharePoint Document Library to store services in such as "Simple Services". Or, use an existing library.
• Click on the file. The HTTP Handler will display the feed in your browser.
• Copy the URL displayed in your browser. This is the URL you will use to call the service from other browsers and/or from the RSSBus SharePoint Web Part.

You can now use the URL to directly access the service, access it from the Web Part, or from another SharePoint server.
