Hello @geoffrey.laurens

You can start with:

• Quick Start - It explains setup and configuration, build and run the consumer example application in EMA package.
• EMA Consumer Tutorials - It explains how to establish an EMA build environment, develop EMA application to consume data step by step with the example source code.

For account/server information that your EMA application should connect to, please contact Thomson Reuters account team/representative.

Ok, i will try it first. Thanks Pimchaya.Wongrukun

Hello @geoffrey.laurens

I can reproduce the problem by connecting to TREP which does not provide component version. After EMA connects to TREP, it tries to get TREP component version. If it fails, the exception is thrown.

According to EMA README, it requires TREP 2.4 or higher. Hence, your TREP should be upgraded or you should connect to another TREP which version is 2.4 or higher.

Hi,

If documentation(README) said this that it means no problem right if i am using this downloaded EMA api to connect to TREP 2.4?

---------------------------------------------------------
Enterprise Platform for Real-Time - RSSL/RWF connections
---------------------------------------------------------
- ADS 2.4 or higher
- ADH 2.4 or higher

Thanks.

Hello @geoffrey.laurens

Yes. I can use EMA to connect to TREP 2.4 and get data. EMA can get ADS version and data:

You can check ADS version by running adsmon on ADS machine. Then, select "Process Statistics", the releaseVersion which EMA get is shown:

However, if ADS version is lower than 2.4 which EMA does not support.

"Process Statistics" of ADS does not have the releaseVersion:
