RFA Jar upgrade from version 5.2 to 8.2 for JAVA technology/API

Hi @wasin.w ,

Thank you for your detailed feedback on my question. Based on your input, I understand that we need to use EMA (Open-source Message Level API) JAR, but it is not an option for my project at this time, and that I have to implement the solution using RFA version 8.2.4.

Additionally, in your previous explanation, you did not cover TibMsg and TibField. We have to implement alternatives to these fields as well. We are using this fields to retrieve data in String or Double format. But Now we can get it in OMM layer?

Existing Implementation:

TibMsg tibMsg = new TibMsg();
tibMsg.UnPack(data);


TibField tibField = tibMsg.Get("string");

String resData = tibField.StringData();

Sorry for late replay but due to some enhancement on LSEG Community website, I'm not able to post new comment or post.

Thank You

Again, Thanks @wasin.w for your quick and detailed answer, it's helping me a lot.

I have implemented code to successfully connect to Reuters and send requests. However, I am currently facing challenges in decoding the response data.

Previously, we used TibMsg for decoding, but as suggested, I am now working with OMMFieldList and OMMFieldEntry. Unfortunately, I am unable to retrieve the correct data.

When parsing the message using GenericOMMParser, I receive the following response:

I need assistance in decoding the following fields:

• ASK
• BSK
• TRAD_DATE
• Q

While debugging, I observe the following:

• OMMFieldEntry.getDataType() always returns 0 (UNKNOWN).
• OMMFieldEntry.getType() always returns 257 (FIELD_ENTRY).

I suspect this might be due to the absence of a Field Dictionary. Could you confirm:

1. Do I need to initialize and load a Field Dictionary to decode these responses?
2. If yes, where can I obtain the dictionary files (e.g., RDMFieldDictionary and enumtype.def)?
3. Are there any specific configurations or steps I need to follow to use these dictionaries in my code?

Your guidance on how to decode the FIELD_ENTRY data and retrieve the required fields will be greatly appreciated.

Thank you for your support.

Note - RFA Version: 8.2.4.L2.all

Hi @wasin.w Thank you for clearing my doubts.

And yes, I’m glad to confirm that I’ve successfully connected to Reuters and decoded the data using the RDMDictionary files and able to get the MARKET_PRICE.

Now @Minh_Hoang let's start with your queries.
Here are the key details and additional information regarding the RFA upgrade:

Key Points to Note:

1. SSL to RSSL Connection Migration:
   • The updated version does not support SSL connections.
   • You must configure an RSSL connection, which requires the following:
     • Provider's HOST
     • Provider's PORT
2. OMM Layer Data Decoding:
   • To decode data in the OMM layer, you need to use RDMDictionary Files.
   • Additional details and implementation references can be found in above comments.
3. Event Handling in processEvent Method:
   • My Implemented events:
     • CONNECTION_EVENTS
     • OMMITEM_EVENTS
   • Within OMMItemEvents, my logic focuses on handling the following MsgType values:
     • REFRESH_MSG
     • UPDATE_MSG
4. Reference Resources:
   • I have implemented the upgradation by following tutorial class/code provided by RFA team only.
   • Key reference java files:
     • StartConsumer
     • LoginClient
     • ItemManager
