Spring MVC gives HTTP 406 for application/octet-stream -


i using spring web mvc , have written controller shall return binary data plugin in web-page show 3d content. plugin uses stk files it's models, have set-up webapp produce kind of contents *.stk urls

the springdispatcherservlet setup handle *.stk requests in web.xml

<servlet-mapping>     <servlet-name>springdispatcherservlet</servlet-name>     <url-pattern>*.stk</url-pattern> </servlet-mapping>

my controller looks this:

@controller @requestmapping(value="/3dobject", produces="application/octet-stream") public class object3dcontroller {      @autowired     private designerservice designerservice;      @requestmapping(value="/{article}.stk", method=requestmethod.get, headers="accept: application/octet-stream")     public void getobject3dforarticle(httpservletresponse response, @pathvariable string article) throws ioexception {         response.setcontenttype("application/octet-stream");         object3d object = designerservice.get3dmodelforarticlenumber(article, languagecode.norwegian);         byte[] content = object.getcontent();         response.setcontentlength(content.length);         ioutils.write(content, response.getoutputstream());     } }

when try access data through browser, following error:

http status 406 - resource identified request capable of generating responses characteristics not acceptable according request "accept" headers.

i have deployed app tomcat server on localhost.

any ideas of must make browser download binary data?

ps! changed *.3do (3d object) *.stk. 3do worked expected, plugin fails error (which hard interpret), have experiment in order verify wether or not url extension matters...

the requestmapping.produces() narrows request , therefore is

only mapped if accept matches 1 of these media types

so need set corresponding accept header in request plugin. cannot done making http request typing in url browser. 1 plugin find useful chrome advanced rest client. there plenty of others offer similar functionality. alternatively try using curl make request correct header.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
