Question

This question is in reference of the question:

Setting the response content-type without using HttpServletResponse

with the following code:

@RequestMapping("handle.htm")
        public ResponseEntity<String> handle() {
        HttpHeaders responseHeaders = new HttpHeaders();
        responseHeaders.setContentType(new MediaType("text", "plain"));
        //responseHeaders.set("myheader","xyz");
        return new ResponseEntity<String>("Hello World", responseHeaders, HttpStatus.CREATED);
        }

I am getting following error:

java.lang.NoSuchMethodError: org.springframework.http.HttpHeaders.readOnlyHttpHeaders(Lorg/springframework/http/HttpHeaders;)Lorg/springframework/http/HttpHeaders;
    org.springframework.http.HttpEntity.<init>(HttpEntity.java:100)
    org.springframework.http.HttpEntity.<init>(HttpEntity.java:70)
    org.springframework.http.HttpEntity.<clinit>(HttpEntity.java:58)
    ...

But in spring API docs there is a static method:

static HttpHeaders  readOnlyHttpHeaders(HttpHeaders headers) 

Then why it is giving such error?

Thanks…

I have had a look in the code, and it must work. Double check everything that you do not use different (old) versions of that jar.
