Hi,
The company where i'm working on are using E.T 2.0 application. my user what to get rates just like what they see in ET 2.0 application. After we discus with thomsonereuters representative in my country they suggest you can connect to TREP using EMA.
I have already download this Elektron-SDK1.0.8.java_0.zip, how to start new EMA project? what lib to include to create new java project? and how do i have to manage my project folder structure?
Thanks in advance.

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.
Hello @geoffrey.laurens
No. All EMA versions require TREP 2.4 or higher. I have checked TREP product and found that TREP2.4 has been end of life(no longer supported) as well. Hence, you should upgrade your TREP to version 2.5 or higher.
I already ask thomsonereuters representative in my country about the TREP version, he said that my company using TREP 2.4. It means, i even can't downgrade the EMA library to lower version? If that so, then i will discuss it first with them...
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:
Sorry Pimchaya.Wongrukun,
I just get an update from thomsonereuters representative in my country, he said that my company are using TREP version 2.2. So i can't test this example. He said they will upgrade TREP to 2.6. Sorry for the mistake. Thanks by the way.
