Java SWIFT Library

Have you looked at WIFE? We use that in our application which translates SWIFT messages to an internal XML format and back again. We haven't had any problems with it. Also, it's licensed under the LGPL, so you can hack it up if you need to. Check it out.

You can combine the open source implementation WIFE with the commercial validation component from http://www.prowidesoftware.com. It validates that the messages you create with the model or XML representation are good through SWIFT network validation rules.

SWIFT is releasing a "Standards Developer Kit" which includes an "MT/XML Schema Library".

From the doc: "The MT/XML Schema Library is a complete set of XML schema definitions for MT messages, and software which shows how to convert messages from an MT format to an MT XML representation and back. This approach allows XML integration between applications while the MT (FIN) format will continue to be transported over the SWIFT network."

Java source code will also be made available, again from the doc: "Working sample Java source code that converts a message in MT format to an XML instance and from an XML instance to a message in MT format."

See: http://www.swift.com/support/drc/develop/standards.page

This can be a great aid in dealing with FIN messages in XML syntax.
