I got the same error if the syntax in the EmaConfig.xml is incorrect.

[Fatal Error] EmaConfig.xml:13:1: XML document structures must start and end within the same entity.
could not construct configuration from file [c:\windows\/EmaConfig.xml]; working directory was [C:\D_DRIVE\temp\Real-Time-SDK-2.1.2.L1.java\Real-Time-SDK-2.1.2.L1.java\setup\RTSDK-2.1.2.L1.java.rrg\RTSDK-2.1.2.L1.java.rrg\Java\Ema\Examples\src\main\java]

It can happen when the application calls the EmaFactory.createOmmConsumerConfig method.

Please share the /tmp/EmaConfig.xml file from the machine that cause this error.

I will test it on my machine.

Thank you for reaching out to us.

According to the error, the API was unable to load the EMA configuration file at /tmp/EmaConfig.xml.

You may check the content in that file or verify the permission of that file.

What is EMA ID? Is it a DACS username or RTO account(client id/username and client secret/password).

If it is a DACS username, it depends on DACS settings. If it is a RTO account, please refer to this Account authorization V1 to V2 migration cheat sheet account article.

hi Jirapongse,

thanks for your feedback!

I have checked the file and not found any problem, this issue not happened for each publication, in fact, this issue occurs for the first time. however it resume normally after this time.

so if the file is invalid or not have permission, it should always throw this issue, right?

according to your explanation, i think it is not RTO account, should be DACS username
