One abstract bean is defined for each available bean class, named after the class's simple name prefixed by "mda.". For example, class="net.shibboleth.metadata.dom.XMLSignatureValidationStage" can be replaced by parent="mda.XMLSignatureValidationStage"; this The definition will also include the init-method and destroy-method properties for the bean when appropriate.

For example:

<bean ... parent="mda.XMLSignatureValidationStage">
    ...
</bean>

Migration assistance

The following beans are defined to assist with migration from previous versions of the MDA framework:

• mda.RelocatedBeanFactoryPostProcessor is an abstract bean providing access to the Shibboleth support class implementing the migration assistance functionality.

• mda.MigrationClassMapis a <util:map> from old class names to new class names.

• mda.MigrationBeanMapis a <util:map> from old bean names to new bean names.

• mda.MigrationAssistanceBean is instantiated in every configuration and references the maps above; if it encounters one of the “old” names it logs a warning message and (where) changes your configuration on-the-fly to refer to the replacement name.

For example:

WARN  - Java class 'net.shibboleth.utilities.java.support.xml.SimpleNamespaceContext',
(Bean ID: commonNamespaces):
This will be removed in the next major version of this software;
replacement is net.shibboleth.metadata.dom.SimpleNamespaceContext

Acting on these warnings is strongly recommended.

If you need to disable this functionality, you can define a mda.MigrationAssistanceBeanof your own after the <include> of the resource; this can be of any type as its only purpose is to override the standard definition.
