This sample demonstrates the use of the Spotfire Streaming CSV Socket Reader to read CSV
data from a TCP socket. The CSV Socket Reader is configured to connect to a server running on
port 9000 of the local computer to read CSV data. The sample comes with a very simple server
written in Java. The source code and compiled JAR of this server can be found in the sample's
directory. The server simply listens on port 9000 and serves the contents of a file at one
line per second to any connections. The default input file is
but you can specify a different file on the command line that starts the server.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, click> .
csv socketto narrow the list of options.
Select CSV socket input adapter from the StreamBase Standard Adapters category.
StreamBase Studio creates a project for the sample.
In the Project Explorer view, open the sample you just loaded.
If you see red marks on a project folder, wait a moment for the project to load its features.
If the red marks do not resolve themselves after a minute, select the project, right-click, and select> from the context menu.
First, run the Simple Server, which is provided as a Java source file. To do this:
Navigate to the
SimpleServer.javaand select > .
Look for a message in the Console view that reports the server is running.
(To change the name of the output text file or the port the server uses by editing values at the top of the Java file.)
CSVSocketReader.sbappfile and click the Run button. This opens the SB Test/Debug perspective and starts the module.
As the server sends lines of the input file to the module, they appear in the Output Streams view.
Press F9 or click the Terminate EventFlow Fragment button. This halts both the EventFlow fragment and the server.
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.
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:
