When updating the MT940 Nuclet (from an older version to a newer one), there is a risk that the adjustments in the Java rules are overwritten.

To avoid this, the following steps are recommended should the MT940 Nuclet be updated to a newer version:

Java classJava packagenecessary work steps
CurrencyWrapperorg.nuclet.mt940.wrapper
  1. clone the class
  2. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.wrapper)
  3. hook the cloned class into the target Nuclet via Nuclet Management
CurrencyFacadeorg.nuclet.mt940.facade
  1. clone the class
  2. adapt the import of the CurrencyWrapper class to the cloned wrapper class
  3. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.facade)
  4. hook the cloned class into the target Nuclet via Nuclet Management
CurrencyFacadeFactoryorg.nuclet.mt940.facadeafter the Nuclet update, enter the cloned CurrencyFacade (in the method getInstance)
   
ReferenceWrapperorg.nuclet.mt940.wrapper
  1. clone the class
  2. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.wrapper)
  3. hook the cloned class into the target Nuclet via Nuclet Management
ReferenceFacadeorg.nuclet.mt940.facade
  1. clone the class
  2. adapt the import of the ReferenceWrapper class to the cloned wrapper class
  3. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.facade)
  4. hook the cloned class into the target Nuclet via Nuclet Management
ReferenceFacadeFactoryorg.nuclet.mt940.facadeafter the Nuclet update, enter the cloned ReferenceFacade (in the method getInstance)
   
ConditionsOfPaymentWrapperorg.nuclet.mt940.wrapper
  1. clone the class
  2. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.wrapper)
  3. hook the cloned class into the target Nuclet via Nuclet Management
ConditionsOfPaymentFacadeorg.nuclet.mt940.facade
  1. clone the class
  2. adapt the import of the ConditionsOfPaymentWrapper class to the cloned wrapper class
  3. Place the class in a Java package of the target Nuclet (e.g. ihr.nuclet.mt940.facade)
  4. hook the cloned class into the target Nuclet via Nuclet Management
ConditionsOfPaymentFacadeFactoryorg.nuclet.mt940.facadeafter the Nuclet update, enter the cloned ConditionsOfPaymentFacade (in the method getInstance)

The cloning only has to be carried out once, i.e. this step is not required on every further update of the MT940 Nuclet.

On a further update it might, under certain circumstances, only be necessary to adapt the wrapper and facade classes to the current specifications from the abstract classes.
