This sample demonstrates the use of the TIBCO StreamBase® RSS Reader for reading RSS data from a website. The RSS Reader is
configured to connect to two popular RSS feeds from nytimes.com
. You must be connected to the Internet for this sample to function properly.
-
In the Package Explorer, double-click to open the
RSSReader.sbapp
application. Make sure the application is the currently active tab in the EventFlow Editor. -
Click the
Run button. This opens the SB Test/Debug perspective and starts the application. The RSS input adapter instance in this application does not start when the application starts.
-
Start the RSS Reader adapter. To do so, open a terminal windows on UNIX, or a StreamBase Command Prompt on Windows, and type the following command:
sbadmin resume default.RSSFeedAggregator
-
As the RSS server sends lines of input to the application, they appear in the Application Output pane.
-
When done, press F9 or click the
Stop Running Application button.
This section describes how to run the sample in UNIX terminal windows or Windows command prompt windows. On Windows, be sure to use the StreamBase Command Prompt from the Start menu as described in the Test/Debug Guide, not the default command prompt.
-
Open three terminal windows on UNIX, or three StreamBase Command Prompts on Windows. In each window, navigate to the directory where the sample is installed, or to your workspace copy of the sample, as described above.
-
In window 1, type:
sbd RSSReader.sbapp
-
In window 2, type:
sbc dequeue RSSFeedOutput
-
In window 3, type:
sbadmin resume default.RSSFeedAggregator
-
Look for the processed tuples containing RSS feed information being output in window 2.
-
In window 3, type the following command to terminate the server and dequeuer:
sbadmin shutdown
In StreamBase Studio, import this sample with the following steps:
-
From the top menu, click

StreamBase Studio creates a single project containing the sample files.
When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.
Important
Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.
Using the workspace copy of the sample avoids the permission problems that can occur when trying to work with the initially installed location of the sample. The default workspace location for this sample is:
studio-workspace
/sample_adapter_embedded_rssreader
See Default Installation Directories for the location of studio-workspace
on your system.
In the default TIBCO StreamBase installation, this sample's files are initially installed in:
streambase-install-dir
/sample/adapter/embedded/rssreader
See Default Installation Directories for the default location of studio-workspace
on your system.
