How i can i get header from response?

Answer 1

getHeaders(...) methods HttpServletResponse are supported since Servlet 3.0., Before this version you can find only setHeader(...) methods.

For earlier version you can try wrapping the response and implement storing the headers in your wrapper class.

Answer 2

Maybe you are using the earlier version of Java. getHeader(String) has been added since its version 3.0. If you want to add it, upgrade your Java version.

Answer 3

http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletResponse.html#getHeader(java.lang.String) says:

Since: Servlet 3.0

setHeader was added in Servlet 3.0. Perhaps your Eclipse instance is using documentation for an earlier version.

Answer 4

HttpServletResponse.getHeader() function is available in HttpServletResponse class.
