This is the Refinitiv Real-Time SDK. This SDK encompasses these Real-Time APIs: Enterprise Message API (EMA) and the Enterprise Transport API (ETA).
The Enterprise Message API (EMA) is an ease of use, open source, OMM API. EMA is designed to provide clients rapid development of applications, minimizing lines of code and providing a broad range of flexibility. It provides flexible configuration with default values to simplify use and deployment. EMA is written on top of the Enterprise Transport API (ETA) utilizing the Value Added Reactor and Watchlist.
The Enterprise Transport API (ETA) is an open source Refinitiv low-level Transport and OMM encoder/decoder API. It is used by the Refinitiv Real-Time Distribution Systems and Refinitiv Real-Time for the optimal distribution of OMM/RWF data and allows applications to achieve the highest performance, highest throughput, and lowest latency. ETA fully supports all OMM constructs and messages. Applications may be written to core ETA, to ValueAdd/Reactor layer or to Watchlist layer.

The Refinitiv Real-Time-SDK supports Oracle JDK 1.8 & 1.11, OpenJDK 1.8 & 1.11.
NOTE: RRT Viewer requires JavaFX which is bundled with open/JDK 1.11 and must be explicitly downloaded if using open/JDK 1.8.
Refinitiv fully supports the use of the EMA Java Edition developers kit on the core linux and windows platforms listed below.
Refinitiv will extend support to other platforms based on the following criteria:
- EMA Java is used with a J2SE 8 compliant JVM
- All problems must be reproducible on one of the core platforms listed below. Refinitiv support teams will only be able to reproduce problems on the core platforms.
The Refinitiv Real-Time-SDK provides support for multicast connections using JNI libraries. Also included are closed source libraries for reliable multicast support and value add cache. These libraries are available for the following platform and compiler combinations:
Platforms:
Windows Server 2012 Enterprise Edition or later 64-bit
Windows Server 2016 Enterprise Edition or later 64-bit
Microsoft Windows 8.1 Professional or later 64-bit
Microsoft Windows 10 Professional 64-bit
Compilers (only on OSs supported by Microsoft):
Microsoft Visual Studio 14.0 (2015) 64-bit (JNI Libraries)
Microsoft Visual Studio 14.1 (2017) 64-bit (JNI Libraries)
Microsoft Visual Studio 14.2 (2019) 64-bit (JNI Libraries)
NOTE: To obtain JNI Libraries for deprecated versions, VS 2013 and VS 2012, please use a BinaryPack from a version prior to Real-Time-SDK-2.0.3.L1 at your own risk as changes to BinaryPacks will not be availble for deprecated compilers.
Platforms:
Red Hat Enterprise Linux 6.X Release 64bit, GCC 4.4.4 (JNI Libraries)
Oracle Linux Server 7.X 64-bit, GCC 4.8.2 (JNI Libraries)
Red Hat Enterprise Server 8.X Release 64-bit, GCC 8.3.1 (JNI Libraries)
CentOS 7.X Release 64-bit Qualification
CentOS 8.X Release 64-bit Qualification
This release has been tested with the following:
Oracle Java SE 8 (JDK1.8)
Oracle Java SE 11 (JDK1.11)
Oracle Open JDK (1.8) -- Linux-only
Oracle Open JDK (1.11)
Proxies:
- Microsoft's Forefront
- Free Proxy
Authentication Schemes:
- Basic
- NTLM
- NEGOTIATE/Kerberos
This release supports encryption for TLS 1.2.
The keystore file is used to contain your own private keys and public key certificates which is used for SSL/TLS handshake with server certificates to create an encrypted connection type. If you do not need to include your own private keys, the API will automatically use the cacerts file as your keystore file. The cacerts file comes with your java installation. If you do need to create your own keystore file, please follow industry standard instructions.
RTSDK Java supports connectivity to the following platforms:
- Refinitiv Real-Time Distribution System (RSSL/RWF connections): ADS version 2.6 and higher, ADH version 2.6 and higher.
- Refinitiv Real-Time: Refinitiv Real-Time Deployed, Refinitiv Real-Time Hosted, Refinitiv Real-Time - Optimized, Refinitiv Direct Feed
NOTE: Connectivity to RDF-Direct is supported for Level 1 and Level 2 data.
This release has been tested with the following:
- ADS 3.5.3
- ADH 3.5.3
- DACS 7.6
Please refer to top level README.md and to Java/Eta/README.md or Java/Ema/README.md files to find more information. In this directory, please find the test plan with test results: RTSDK-Java-Edition_Test_Plan.xlsx
Please refer to Installation Guides for ETA and EMA for detailed instructions. In this section are some basic details.
This section shows the required setup needed before you can build any of the Java APIs.
Obtain the source from this repository on GitHub. It will contain all of the required source to build RTSDK as detailed below. In addition, this repository depends on a Binary Pack found in the release assets section that is auto pulled by a build. The BinaryPack contains libraries for the closed source portions of the product, permitting users to build and link all dependent libraries to have a fully functional product.
Refinitiv Real-Time SDK package may also be downloaded from Refinitiv Developer Portal.
Refinitiv Real-Time SDK package is also available on MyRefinitiv.com.
Using Gradle:
Gradle is now used to build RTSDK. Gradle can be downloaded from https://gradle.org NOTE: Starting with SDK version 1.3.1, please use Gradle version 5.X which supports JDK1.11 and no longer supports JDK1.7.
Refer to the RTSDK Java Installation Guide for more detailed Gradle build instructions than what is described below.
Navigate to RTSDK/Java and issue the appropriate Gradle command as follows:
Windows: gradlew.bat jar
Linux: ./gradlew jar
This command builds the jar files.
To run an example, issue the appropriate command as follows:
Windows: gradlew.bat runExampleName --args='<arguments>'
Linux: ./gradlew runExampleName --args='<arguments>'
Issue the following command to get a list of all example names.
ETA Windows: gradlew.bat Eta:Applications:Examples:tasks --all
ETA Linux: ./gradlew Eta:Applications:Examples:tasks --all
EMA Windows: gradlew.bat Ema:Examples:tasks --all
EMA Linux: ./gradlew Ema:Examples:tasks --all
ETA example, the following command runs the VAConsumer example.
Windows: gradlew.bat runVaConsumer --args='-c localhost:14002 DIRECT_FEED mp:TRI'
Linux: ./gradlew runVaConsumer --args='-c localhost:14002 DIRECT_FEED mp:TRI'
EMA example, the following command runs the example270__SymbolList example.
Windows: gradlew.bat runconsumer270
Linux: ./gradlew runconsumer270
To debug a encrypted consumer connection, you can add the following JVM argument:
-Djavax.net.debug=all
This provides SSL/TLS details that can be useful if SSL/TLS handshake failed
The Refinitiv RDMFieldDictionary and enumtype.def files are present in this GitHub repo under Java/etc. In addition, the most current version can be downloaded from MyRefinitiv.com. Search for "Service Pack" and choose the latest version of Refinitiv Template Service Pack.
For ease of product use, as of the RTSDK 1.2 release, Refinitiv maintains its RTSDK Jar files on Maven Central.
You can download RTSDK libraries and dependencies from Maven Central using several different tools, specific procedural instructions are not included here. Maven uses the following syntax to specify RTSDK dependencies (this is sample code) :
<dependency>
