If you have ideas please help me.

Answer 1

Finally i found answer according to Balaji V answer. I changed my request,

multiMap.set("grant_type", "password ");

I removed space of "password " as "password". Also changed multiMap.set("scope ", "PRODUCTION"); line. "scope " as "scope".

But again came another error.I had to change "TokenResponse " method data type as String. And return String.
