Sample Overview

This topic describes how to run the Spotfire Streaming for CME MDP3 Adapter sample application, which illustrates how to use the adapter to access CME MDP feeds. For more information on this adapter, see CME MDP3 Adapter.

This sample includes a CME MDP3 adapter, which by default connects to channel 311 of CME's NRCert testing environment and is assumed to already be running and accessible from your machine. Once launched, use the sample to access market data messages from that channel.

Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

  • From the top-level menu, select File>Import Samples and Community Content.

  • Enter cme to narrow the list of options.

  • Select CME Market Data MDP3 from the Market Data Adapters category.

  • Click Import Now.

StreamBase Studio creates a project for the adapter in your current Studio workspace.

Running This Sample in StreamBase Studio

The steps to run this sample in Studio are as follows:

  1. In order run, the adapter requires that the open-source Java Market Data Handler for CME Market Data (MDP 3.0) from EPAM Systems be installed on development and deployment machines that are expected to run StreamBase applications that call this adapter. You can obtain the Data Handler software from public.tibco.com.

    Once you download the above zip file, extract its contents to a temporary location and Maven install the following JAR files to your Maven repository:

    • Install the b2bits-jmdp3-2.0.2-mbp-with-mbo/b2bits-jmdp3-2.0.2.jar file to the local Maven repository with a mvn command like the following: 

      mvn install:install-file 
  -Dfile=b2bits-jmdp3-2.0.2-mbp-with-mbo/b2bits-jmdp3-2.0.2.jar 
  -DgroupId=com.epam.cme.mdp3
  -DartifactId=b2bits-jmdp3 -Dversion=2.0.2 -Dpackaging=jar

    • Install the b2bits-jmdp3-2.0.2-mbp-with-mbo/lib/b2bits-jmdp3-core-2.0.2.jar file to the local Maven repository with a mvn command like the following: 

      mvn install:install-file 
  -Dfile=b2bits-jmdp3-2.0.2-mbp-with-mbo/lib/b2bits-jmdp3-core-2.0.2 
  -DgroupId=com.epam.cme.mdp3 
  -DartifactId=b2bits-jmdp3-core -Dversion=2.0.2 -Dpackaging=jar

  2. Add these JAR files as Maven dependencies with steps similar to the ones described in 2. Add a Dependency.

  3. 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 Maven>Update Project from the context menu.

  4. You must also download config.xml and templates_FixBinary.xml files from CME's publicly-accessible FTP site (see https://www.cmegroup.com/confluence/display/EPICSANDBOX/MDP+3.0+-+FTP+Site+Information) and place both files in your project's src/main/resources directory.

  5. After copying the two .xml files to your project src/main/resources folder, right-click and run Maven>Update Project to clear the red marks from the project folder in the Project Explorer view.

  6. In the Project Explorer view, double-click to open the mdp3.sbapp application.

  7. Make sure the application is the currently active tab in the EventFlow Editor, then click the Run button. This opens the SB Test/Debug perspective and starts the module.

  8. The adapter is expected to connect to the channel's various feeds and the data should start flowing.

  9. When done, press F9 or click the Terminate EventFlow Fragment button.

This Sample's Files

This sample contains the following files:

  • The sample EventFlow application, mdp3.sbapp.

  • subscriptions.csv, an optional file containing the IDs and names of instruments to which to subscribe upon connection.

Sample Location

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_cme-mdp3

See Default Installation Directories for the default location of studio-workspace on your system.
