Calling the Validation Methods in your Collaboration (SWIFT Integration Projects)

Calling the Validation Methods in your Collaboration

The validation methods are available at the OTD level, and can be called after the OTD is populated with it’s values. This usually occurs after a message is unmarshaled in the OTD.

The following fragment of code demonstrates the use of the validate method within a Collaboration. In this example, validate() is called and either “message OK’ or the exception error String is written to the log.
