JAVA TO SWIFT CONVERTER ONLINE CODE
This API is the base foundation of the high level Sequences API.Your question isn't really directly related to MQ, as MQ is just carrying whatever data format your applications are using, and doesn't have the ability to transform messages other than to translate code sets. At this API level the message body can be think of as a text string, where instead of characters we found message fields and we can get for example all Tags before a given one, Tags between boundaries, etc. The SwiftBlock4 object basically contains an ordered List of fields found content body of the SWIFT message and provides several API to manipulate and get the tags individually or by sub blocks. The "val32a" String will contain the value "050902JPY3520000," and "list71" will contains a list of Strings with values "EUR12,00" and "EUR2,34". String list71 = m.getBlock4().getTagValues("71F") //get a repeated value tag
Reading fields like simple tuples of name and value makes the parser very efficient, while additional content parsing can be done with the message model in a following step.įor the example, the following code can be use to gather some fields of the parsed message using the generic low level model: String val32a = m.getBlock4().getTagValue("32A") //get a simple value tag So the parser will basically split the message content into the three primary elements that defines an MT message the message itself, it's blocks, and the tag (or fields) inside each block. The result of the parser is the backbone model implemented by the SwiftMessage class. SwiftMessage m = (new SwiftParser()).parse(fin) ĭirect usage of the SwiftParser class is discouraged but in may be useful on certain conditions where the lenient mode of the parser must be explicitly controlled by your application. Direct usage of the SwiftParserįinally, the actual parser implementation class is another option to translate a raw message in its Java model object.
Sm = SwiftMessage.parse(sm.getUnparsedTexts().getAsFINString()) Īt this point the sm variable will contain the actual user to user message, regardless if it was preceded by and ACK.įor more information on the ACK/NAK structure see Processing ACK/NAK. The following example will parse the FIN content, check for the service id, and if it is a system message it will then gather the actual MT from the unparsed content: SwiftMessage sm = SwiftMessage.parse(fin) However if this is the way you receive the messages from the SWIFT interface and you need the actual user message following the ACK, then you have to do something else. If you are trying to match and process the ACK/NAK notifications you may be interested on the service message. When dealing with this scenario it is the user responsibility to check whether the message is a service message or not, and proceed accordingly, depending on the particular use case and application needs. This is just fine when reading plain user to user messages, but when the message is preceded by a service message as in the example, the resulting parsed object may not be the expected one. If you pass the above content to the parse method, by default the parser will get the first FIN message found in the file (the ACK service message), leaving the rest of the text into the UnparsedTextList structure. This class provides static methods to parse an unknown message from a String, File or InputStream.įor example consider the following SWIFT message example: In situations where the message type is unknown, the easiest and recommended way to read and parse messages is by means of the abstract class AbstractMT. The parser functionality has different entry point depending on the use case: Generic processing of unknown messages All the information is read and put in a suitable object of the message model regardless of the message being SWIFT compliant. The parser always performs a best effort heuristic to parse the message even if it is not well formed. The parser provides functionality to convert SWIFT messages FIN text into the Java message modelīy doing this, you can work with SWIFT messages focusing on the data and not having to deal with low level syntax details.
