Implement it in java and other questions - prowide iso 20022?

[anderson-indiano]

Is there any material (free document) available from PROWIDE ISO 20022 explaining how we can implement it in the JAVA/ MAVEN?

[pauljohe-dnb]

It's available in maven central already (as explained in the readme). Here is the code though to the most recent version:

<dependency>
  <groupId>com.prowidesoftware</groupId>
  <artifactId>pw-iso20022</artifactId>
  <version>SRU2021-9.2.4</version>
</dependency>

[anderson-indiano]

Thanks. Please have any example application using this dependency(pw-iso20022) in maven? I only found applications with gradle.

Hi,

You have some use case examples at https://github.com/prowide/prowide-iso20022-examples/tree/main/src/main/java/com/prowidesoftware/swift/samples

The example project uses Gradle, but you can create a typical Maven project including the dependency as Paul mentioned. There are no particular Gradle/Maven requirements. This is a standard Java library.

Hi, Thanks.

Hi. Please, there are some examples where you get the ISO 20022 message through an MQ queue and turn this message into a standard .TXT file SWIFT FIN.

[zubri]

Hi,

Notice this open source library provides the model, parser and builder API For ISO 20022 messages.

MQ integration and translation between ISO 20022 and MT are out of scope.
You could contact www.prowidesoftware.com for that, to explore commercial product options.

Hi,

I'm trying to add the values ​​of an mx message (default pacs.0800.001.08) to the fields of an mt103.
Could you please tell me what are the xml methods to get their values ​​and assign to the fields: Field32A, Field50F, Field52A, Field57A, Field59F, Field70,Field71A?

Example: mt103.addField(new Field20().setReference(pacs.getFIToFICstmrCdtTrf().getGrpHdr().getMsgId()));

[zubri]

Conversion of pacs.008 into MT103 is not straight-forward. There are many things to considered because both the MX and the MT have more than one option for the business content.

For the reference in field 20 as in your example is simple, but then for instance the value date that goes into 32A you could find it in the group header and also in the credit transfer within the pacs. So you have to check which one is present and set it accordingly.

Then things are more complex for the orderer, beneficiary, intermediaries, etc... You could have the name and address in the MX or the BIC code, or even a clearing system code. And you have to create the specific field in the MT depending on what content you have found in the MX.

It is not a 1 to 1 simple list we could provide here.

[anderson-indiano]

Thank you Zubri!

[anderson-indiano]

Hi,

Please, can you help me?

How can I validate if it has the field(tag 23B, 32A) in the mx file?

Example:
MxPacs00800108 mxPacs00800108 = (MxPacs00800108) mx;
Field32A field32a = new Field32A();
if (field32a.asTag() ???)) {
System.out.println("test");
}

[zubri]

You appear to have some confusions regarding the MT and ISO 20022 (MX) standards. Field 32A is an MT field. It has an equivalent element in the pacs.008 XML structure. But there is no "field 32A in the MX".

Also, this "GitHub Issues" is intended for reporting specific bugs of the open source ISO 20022 library. Not general consultancy questions for the standards.

Notice you would need a much more deep understanding of the standards to code a translation from scratch. You might be interested on this commercial library: https://www.prowidesoftware.com/products/integrator/translations

Hi,
Can you please answer me a question?
Does the Prowide library parse all fields coming from an xml message? For example, if I receive an xml message with 5,000 fields, can the Prowide library parse all the fields from the xml message?

[zubri]

If the XML elements match the message schema yes. There is no size limitation in the model/parser.
If the elements do not match the model, they are simply discarded by the parser.

[anderson-indiano]

Hi,
Got it, there is no limitation of parse in xml with prowide.
And, if the message contains any fields other than the classes mapped in the library, the parser will not run.
Only those that are the same in the classes mapped in the library. Right?

[zubri]

Elements not contained in the mapped model are silently ignored. The parser will load the rest. The provided parse methods are just a facade on top of the Java jaxb unmarshaller.

[anderson-indiano]

Thanks Zubri!

[anderson-indiano]

Hi,

Can you please answer me a question? Do you have a prowide ISO 20022 library available, but can XSDs also be available?

[zubri]

You can get ISO 20022 schemas from the ISO 20022 org web site.
Or from swift.com if you are a member.
We are not allowed to distribute ISO schemas in an open source library.

[anderson-indiano]

Thanks!

This indicates you are missing the prowide code library dependency. Or if you are using Java 9+ modules, maybe you need to enable the core module explicitly: Automatic-Module-Name: com.prowidesoftware.core
