Message Translator CBPR+ Demo

The project is here to demonstrate how our SDK for CBPR+ Message Translator works. For our demonstration we are going to use the demo SDK which can translate MT to CBPR+ messages.

This documentation describes how to incorporate the CBPR+ Translator Library into your project. The SDK is written in Java.
By following this guide you will be able to translate MT(ISO 15022) messages to CBPR+ messages and vice versa according to CBPR+ guidelines.

It's a simple maven project, you can download it and run it, with Java 1.8 or above.

SDK setup

Incorporate the SDK jar into your project by the regular IDE means.
This process will vary depending upon your specific IDE and you should consult your documentation on how to deploy a bean.
For example in Intellij all that needs to be done is to import the jar files into a project. Alternatively, you can import it as a Maven or Gradle dependency.

Instructions

Auto Translation

You have the option to provide the MT or CBPR+ message and the library auto translates it to its equivalent.
Input should be in text format.
Output could be either in text format or an Object.
You need to call the following static methods of CbprTranslator class.
In case of no error of the input message, you will get the translated message.
Translated message is not validated.

public static String translateMtToMx(String mtMessage) throws InvalidMtMessageException, StopTranslationException, TranslationUnhandledException

public static CbprMessage translateMtToMxObject(String mtMessage) throws InvalidMtMessageException, StopTranslationException, TranslationUnhandledException

public static String translateMxToMt(String mxMessage) throws InvalidMxMessageException, StopTranslationException, TranslationUnhandledException

public static SwiftMessage translateMxToMtObject(String mxMessage) throws InvalidMxMessageException, StopTranslationException, TranslationUnhandledException

In case you want to get a full truncation report, you need to call the following static method of CbprTranslator class.

public TranslationResult<SwiftMessage> translateMxToMtFull(String mxMessage, String direction) throws InvalidMxMessageException, StopTranslationException, TranslationUnhandledException

public static TranslationResult<CbprMessage> translateMtToMxFull(String mtMessage) throws InvalidMtMessageException, StopTranslationException, TranslationUnhandledException

TranslationResult has the following methods:

• getMessage() - Returns the translated message in text format.
• getErrorList() - Returns the list of TranslationError objects.

Explicit Translation

If you do not want to use the auto-translation functionality, you can call directly the Translator you want.
In this case you need to know the exact translation mapping.
Translator classes implement the MtToCbprTranslator or CbprToMtTranslator interface.
The translate(Object), does not validate the message.
The translate(String), validates the message.
Translated message is not validated.

MtToCbprTranslator interface provides the following methods for both text and object format translations.

String translate(String swiftMtMessageText) throws InvalidMtMessageException, StopTranslationException, TranslationUnhandledException;

CbprMessage translate(SwiftMessage swiftMtMessage) throws StopTranslationException, TranslationUnhandledException;

CbprToMtTranslator interface provides the following methods.

String translate(String cbprMessageText) throws InvalidMxMessageException, StopTranslationException, TranslationUnhandledException;

SwiftMessage translate(CbprMessage cbprMessage) throws StopTranslationException, TranslationUnhandledException;

SwiftMessage[] translateMultipleMt(CbprMessage cbprMessage) throws StopTranslationException, TranslationUnhandledException;

The method translateMultipleMt translates a CBPR+ message to multiple MT messages. Until now, no translation uses this method.

Both MtToCbprTranslator and CbprToMtTranslator interfaces provide a method to get the translation error list.

List<TranslationError> getTranslationErrorList();

For the structure of TranslationError see Error Handling.

In case that a translation uses this logic, the translation in text format will return the MT messages splitted with $.
For example:

:56A:INTERBIC
-}${1:F01TESTBICAXXXX1111111111}

Specifically for Pacs009 to Mt205 and Pacs009COV to Mt205Cov, Translators Pacs009ToMt202Mt205 and Pacs009ToMt202Mt205COV respectively, you need to use setters Pacs009ToMt202Mt205.setTranslateTo(String translateTo) and Pacs009ToMt202Mt205COV.setTranslateTo(String translateTo) to specify that you want to translate a Pacs009 to an Mt205 or it will always be translated to an Mt202.

Pacs009ToMt202Mt205.setTranslateTo("205");
Pacs009ToMt202Mt205COV.setTranslateTo("205");

Message Validation

In order to validate the translated MT message, you can use MtMessageValidationUtils.validateMtMessage(SwiftMessage mtMessage), MtMessageValidationUtils.parseAndValidateMtMessage(String message) or any other way you prefer.
In order to validate the translated CBPR+ message, you can use CbprMessageValidationUtils.parseAndValidateCbprMessage(A appHdr, D documentMessage, CbprMessage.CbprMsgType cbprXsd) where CbprMsgType can be retrieved from CbprMessage.extractCbprMsgType(), CbprMessageValidationUtils.autoParseAndValidateCbprMessage(String message) or any other way you prefer.

Error Handling

InvalidMtMessageException & InvalidMxMessageException

When you translate a message, input message is validated. For example, in a MT→MX translation, the first step is to validate the MT message and we proceed to translation only if the message is valid.
This is the reason why this direction throws InvalidMtMessageException.
The other direction throws InvalidMxMessageException.
Both Exceptions contain a validationErrorList attribute which contains a description of the errors occurred.

StopTranslationException

When there is a condition in input message that obstructs the translation, a StopTranslationException is thrown which contains a translationErrorList. The TranslationError has the structure:

• errorCode
• errorCategory
• errorDescription

TranslationUnhandledException

When there is an exception that is not known, like NullPointerException, an TranslationUnhandledException is thrown the actual exception is attached as the cause.

Translation Error List

Each Translator class has a translationErrorList attribute which contains a list of TranslationError objects. You can access this list by calling the getTranslationErrorList() method of each Translator.
The TranslationError has the below structure:

• errorCode
  • errorText - Mandatory field which contains the error code - e.g. T0000T
  • errorCategory Mandatory field that contains the error category - e.g. TRUNC_N
  • errorDescription - Mandatory field that contains a more detailed description for the error - e.g. Field content has been truncated.
• originalFieldPath - Optional field which contains the path of the original message - e.g. NtryDtls/TxDtls/Refs/EndToEndId
• targetFieldPath - Optional fields that contains the path of the translated message - e.g. Tag61
• originalValue - Optional field that contains the original value - e.g. MUELL/FINP/RA12345
• alteredValue - Optional field that contains the altered value e.g. MUELL/FINP/RA12+

Modify the generated message

Once you have the translated message in text format, you can use our other Financial Messaging Libraries (Other Resources) in order to create a Java Object and make any changes you want.

In order to create an CBPR+ Java Object from text use the below code. The class FIToFICustomerCreditTransfer08 may vary depending on the ISO20022 Message Type.
Other message types are available here

CbprMessage<BusinessApplicationHeader02, FIToFICustomerCreditTransfer08> cbprMessage = new CbprMessage(new BusinessApplicationHeader02(), new FIToFICustomerCreditTransfer08());
cbprMessage.

parseXml(translatedMessageText);

BusinessApplicationHeader02 businessApplicationHeader02 = cbprMessage.getAppHdr();
FIToFICustomerCreditTransfer08 fiToFICustomerCreditTransfer = cbprMessage.getDocument();

//In case you want to enclose the CBPR+ message under another Root Element, use the code below
cbprMessage.

encloseCbprMessage("RequestPayload"); //In case you want RequestPayload

In order to create an MT Java Object use the below code.

SwiftMessage swiftMessage = new SwiftMsgProcessor().ParseMsgStringToObject(translatedMessageText);

Code Samples

In this project you can see code for all the basic manipulation of an MT or CBPR+ message, like:

• Translate MT to MX
• Translate MX to MT
