We have a servlet written in java which create http post requests, we need something to manages server responses.
1. About five requests
2. About 20 erros types
We have three actors:
Client - Servlet - External service
The servlet is the one we are going to work on.
1. An external client calls via http the servlet specifying in parameters the kind of request to do and its data.
2. The servlet builds the corresponding new http post message, attaches digital signature and send it to an external service
3. The servlet waits for a response from the external service
4. In case of positive response, parse response content and send xml data to client
5. In case of error the servlet writes text logs, manages eventul retries and send xml data to client
