Good morning. I have a web application made with symfony2 (php), in which I have a form with some data, which I want to send to my other web application made with spring (java). What technology and / or technologies should I use to achieve this communication?
Note: In the application that I have with spring I have REST services, I can not create another service for communication, since all those services I have protected, and if I create one to achieve the connection that I mentioned, the application would be vulnerable, since I would have to make a protection exception for that service. For which I need another way to achieve this communication.
Thank you in advance.
