[EMA]How to build "Article.EMA.Java.ChainExpander" with Elektron-SDK1.2.2.java

luxiangyuan · November 2018

hello

I want to build "Article.EMA.Java.ChainExpander" with "Elektron-SDK1.2.2.java".

"Elektron-SDK1.2.2.java" has been build successfully.

But I get errors when I build "Article.EMA.Java.ChainExpander".

I set the JAVA_PATH as follows:

set ELEKTRON_JAVA_HOME=E:\srcRefer\Elektron-SDK1.2.2.java\setup\Elektron-SDK1.2.2.java.rrg\Java

it looks that there are some errors of the ema.jar version

errors:

You can modify the scripts in this question to support SDK1.2.2.

Three files must be modified with the version number of SDK.

1. Article.EMA.Java.ChainExpander\build322.bat

2. Article.EMA.Java.ChainExpander\ValueAddObjectsForEMA\build322.bat

3. Article.EMA.Java.ChainExpander\ValueAddObjectsForEMA\Manifest322.txt

Class-Path: ema-3.2.2.0.jar upa-3.2.2.0.jar upaValueAdd-3.2.2.0.jar commons-configuration-1.10.jar commons-lang-2.6.jar commons-logging-1.2.jar commons-collections-3.2.2.jar slf4j-api-1.7.12.jar slf4j-jdk14-1.7.12.jar

Hi @luxiangyuan,

The version of the ChainExpander was built and tested with Elektron-SDK1.1.x. The Elektron-SDK1.2.x package has changed it's structure and modules which is why the build fails. I have contacted the owner and the package will be updated in the future. I would encourage you to post this as an issue here: https://github.com/TR-API-Samples/Article.EMA.Java.ChainExpander/issues

To move forward, I would suggest one of two things. You can try/test the example with an older version of Elektron-SDK (version 1.1.x) or modify one of the build scripts to work with the version of Elektron you have installed. I was able to modify the build.bat script within the ValueAddObjectsForEMA subdirectory to look like this:

After these modifications, the script will complain about the copying of some files which you can ignore. I was able to follow the instructions and successfully run the example.

Hope this helps.

Hi @luxiangyuan,

I see a few mistakes in your attached 'build.txt' file. Please refer to my changes above and ensure they are the same. This is what I found:

Hi @luxiangyuan

Did you add the ELEKTRON_JAVA_HOME environmental variable to point to your SDK installation?

I set mine to

set ELEKTRON_JAVA_HOME=C:\Reuters\ElektronJ1.2.2

Please find attached the batch file I used to build using 3.2.2 sucessfully.

Thanks Umer, I will mention this to Olivier. The git project links to the older version of the ValueAddObjectsforEMA which is why I (and most people) would miss it. Let me instruct the user to refer to the updated submodule.

Hi @luxiangyuan,

If you are still having troubles getting this to work, there was a recent patch uploaded to the ValueAddObjectsForEMA submodule. In there is a patch named: build321.bat that will work with SDK1.2.1 but @umer.nalla attached a modified version of this file so it works with your version SDK1.2.2.

This should allow you to move forward.

thanks.
