Hi,
which RAP version are you using. RAP application can't be started with a
POST request - see:
416445: Adding ability to start RAP application with HTTP POST request
https://bugs.eclipse.org/bugs/show_bug.cgi?id=416445
Currently, all POST request to RAP application *must* contain JSON
protocol message [1].
Since RAP 2.1.1 (including 2.2) POST request that have a content-type
different than "application/json" will lead to HTTP 400 response. See:
413668: Cross Site Request Forgery vulnerability (aka CSRF/XSRF)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=413668

Best,
Ivan
