Retrieving Connection Metadata
When a user of the adapter creates or edits a connection node, Integration Server interrogates the connection factory implementation to retrieve the metadata as follows:
1. Gets the adapter name, version, and JCA version, as shown in steps 1 to 3 in the figure.
2. Instantiates the connection factory if it is not already cached, and introspects the connection factory for the metadata parameters, as shown in step 4 in the figure. Integration Server retrieves the set accessor methods.
3. Calls the get method for each metadata parameter (if present) and retrieves any default values that may be provided for those parameters, as shown in steps 5-6 in the figure. While get methods may have other uses in the implementation, this is their only use from the ADK's perspective.
4. Calls the fillWmDescriptor method of the connection factory, as shown in step 7 in the figure. The fillWmDescriptor method can specify the order in which the parameters must appear on the adapter's administrative interface, set display names, and constrain input of the users of the adapter.
