I’m developing a Java application to publish market data to TREP. After reading some documentation, I found that I need to use the following JAR files: ema-3.8.3.0.jar, logback-classic-1.2.11.jar, eta-3.8.3.0.jar, logback-core-1.2.11.jar, slf4j-api-2.0.16.jar, and json-20240303.jar. The documentation also mentions that I need ema.so and eta.so files. Do I need to manually compile RTSDK-2.2.3.E1.linux.rrg to generate these two .so files?
Additionally, I’m using OpenJDK version “11.0.26.” Is this version compatible, or do I need a higher version of the JDK?

    Hello @ianzhu

    The OpenJDK version 11 is supported by RTSDK Java edition. You can check the API Compatibility Matrix and RTSDK README.md file (also available in the SDK package - download here).

    About "publishing market data to RTDS", how are you going to do that? Are you using the

    Based on my understanding, the EMA Java does not require ema.so and eta.so files for the RSSL connection contribution, publication. Which document that mention it?

    However, if you really need those files, you can download the RTSDK C/C++ SDK and BinaryPack packages from RTSDK C/C++ Download link.

    Hello @ianzhu

    Cherry picking the JAR files from the package is not a good idea. I would suggest that you download the whole RTSDK package which includes all the binary pack files as well.

    Once SDK is installed, you can start from the Quickstart and move on to the tutorial section to learn about publishing.

    The SDK and binary assets are also available on the GitHub.

    I don't see a dependency on ema.so mentioned anywhere.
