How do I go about setting up a TREP RFA API environment in java?

You can refer to Creating a barebones RFA application in Java to help you set up an API environment to build RFA Java applications. In addition, the RFA Java Dev kit contains examples which will also assist in understanding what is required to build your applications.

Hello @josa

To setup RFAJ Configuration, please refer to Tutorial 2 - Understanding RFA Java Configurations

Thanks @nick.zincone.1 and @Pimchaya.Wongrukun.

I followed the instructions and tried running Tutorial_06 and I could not get Login Successful message. Am running Java 8 example. Is there anything am doing wrong?

Hi josa,

There are 2 key items you need to confirm are correct:

1. Server (ADS) hostname/IP
2. Login user name

I can see from above you are likely using the packaged 'RunConsumer.bat' script which uses the username: 'user'. You may need to change this if your market data environment has permissions enabled. Secondly, confirm your ADS host name, i.e. 'serverList' defined within your RFAJava_Config.xml is correct.

If you are looking to create a market data consumer application in Java and are not restricted to using RFA, I would highly encourage you to consider using the Elektron Message API (EMA).

Hello josa,

You should confirm ADS host/port and login user name if they are correct with:

-Thomson Reuters Account team if you connect to Thomson Reuters Server

or

-Your ADS admin if you connect to your company server

If all are correct:

a) Check if the server and
port is available using telnet <server> <port>

b) Check with your
network admin if the firewall allows your machine sends/receives messages to/from the server.

Hi @nick.zincone and @Pimchaya.Wongrukun, the problem am having in the first place is that we don't have a company server set up for TREP RFA data. Question is how do we set this up? I have been using my development machine for this hence am having this problem. Could you help please provide info on how to set this up?

Thanks @nick.zincone.1 and @Pimchaya.Wongrukun.

Hello @josa

The overall system that RFA gets data:

a feed -> TREP -> RFA

Now you have RFA but you need a feed and TREP to be able to consume data.

You should contact Account team,Andrew Forman(andrew.forman@thomsonreuters.com) who can provide you with the solution which serve your requirements. e.g. the proper feed, TREP components that you need to install or use Thomson Reuters's TREP.

josa

Thanks @Pimchaya.Wongrukun. Will contact Andrew and let you know if am still having issues setting this up.

Hi @josa,

Alternatively, if your goal is to test connectivity and see data coming through, you may be able to use the interactive Provider example within the RFA package. In general, a Consumer connects to a Provider. In the typical case, when you write an RFA Consumer, you connect into TREP, specifically the ADS component which acts as a Provider of data. So in theory, you can try to build both the Consumer and Interactive Provider examples and wire them up to see data flowing through. Something to consider.
