This sample demonstrates how to use the TIBCO StreamBase® Input Adapter for IP/HTTP.
Note
This adapter uses the WinPcap libraries for Windows to tap into the IP packet stream. Before using this adapter with real-time data, you must install and configure these libraries on the system that will host the adapter.
Download and install the latest WinPcap MSI from http://www.winpcap.org. Use all the default settings for the installation. This adapter is not supported on Mac OS X or Linux.
-
In the Package Explorer, double-click to open the
httpReader.sbappapplication. Make sure the application is the currently active tab in the EventFlow Editor. -
Click the
Run StreamBase Application button. (Not the Run button.) This opens the SB Test/Debug perspective and starts the application.
-
Use a web browser to generate traffic on HTTP port 80.
-
In the Application Output view, observe that one or more tuples is emitted through the HTTPReaderOutput stream.
-
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 two terminal windows on UNIX, or two 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 httpReader.sbapp. -
In window 2, start a dequeuer by typing:
sbc dequeue HTTPReaderOutput. -
Use a web browser to generate traffic on HTTP port 80.
-
One or more tuples representing the HTTP request and response messages appear in the dequeuer terminal.
-
In window 2, type: Ctrl+C to exit the sbc session.
-
In window 2, type the following command to terminate the server:
sbadmin shutdown
In StreamBase Studio, import this sample with the following steps:
-
From the top menu, click → .
-
Select this sample from the Embedded Input Adapters list.
-
Click OK.
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 permission problems. The default workspace location for this sample is:
studio-workspace/sample_httpreaderSee Default Installation Directories for the default 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/httpreaderSee Default Installation Directories for the default location of studio-workspace on your system.
