[Adding Azeez] Hi,
In relation to the offline discussion we had, it was clear that the above functionality is not sufficient for your requirement. As per the offline discussion, the suggested approach was to use custom contexts. [1] </>, [2] <https://www.blackpepper.co.uk/blog/custom-context-providers-for-cxf-with-the-context-annotation> describes an Apache CXF example of using custom contexts. Currently in MSF4J using @Context annotation we can inject the Request, Response, HttpStreamer, FormParamIterator and MultivaluedMap instances. However, these are not accessible via interceptors as per the current implementation. The approach we were using to inject values is by using the approach I have explained in the previous email. Therefore to solve the above problem, there are 2 solutions we can introduce to MSF4J. 1. *Introduce custom injection and lifecycle management [1] <https://jersey.java.net/documentation/latest/ioc.html>, [2] <https://www.blackpepper.co.uk/blog/custom-context-providers-for-cxf-with-the-context-annotation> to MSF4J.* Using this approach what you should basically do is: - Write a custom context provider of your own which will describe how the injected value is generated by implementing a certain interface. - Register the custom context provider to the MSF4J - Inject the value using @Context annotation (Ex:- @Context(String key) Object[] arguments) 1. *Have a Map<String, Object> map that could be injected using @Context annotation* Using this approach what you basically do is: - Add the arguments you need to inject using the @Context annotation using @SetContext(String key, Object value). This can be done inside interceptors or HTTP methods - Inject the value to using @Context(String key) WDYT?
