Hi all, I'm currently working on the $subject and ran into a blocker while tackling serialization with injected environmental variables.
In earlier applications of parameter injection (eg: WSDLEndpoint, AddressEndpoint) how I achieved injection is by modifying a particular setter method in the respective endpoint to ingest an environment variable value while preserving the original variable name. Latter was done to make serialization possible. An example is included herewith: [image: Selection_558.png] While working on RecipientList endpoints I've identified 2 parameters that are candidates for injection; httpPort and httpsPort. The XML value extraction happens in the factory in the method linked herewith: https://github.com/apache/synapse/blob/610baef00b1824d7d1341491ecc7f7d9b15485d3/modules/core/src/main/java/org/apache/synapse/config/xml/endpoints/RecipientListEndpointFactory.java#L147 The issue I'm facing is that the extracted parameters are populating a class named *Member* which is provided by Axios2 which I cannot edit. While performing the injection in the factory works for deserialization, it doesn't work for serialization, which requires preserving the original environmental variable name, ideally in the Member class. I suppose extending Member and creating a new class for this purpose is a solution, however, I'm unsure if that would have cascading issues with other components of Synapse. Looking forward to hearing your feedback on this as well as alternative solutions. Best -- *Nuwan Jayawardene* https://www.linkedin.com/m/in/nuwanjaya
