angular - Tomcat 7 server is not sending CORS headers -


i writing angular 4 application makes authenticated connection tomcat 7 server. webapp on tomcat server has rest api. have local copy of server on 1 of machines, using request url this:

http://xyz.local:8080/poolparty/api/projects

i using safari request , if check disable cross-origin restrictions menu item json package returned , can display in browser. if don't check menu item error:

failed load resource: preflight response not successful

i have checked cors filter configuration in server, , looks this:

<filter>   <filter-name>corsfilter</filter-name>   <filter-class>org.apache.catalina.filters.corsfilter</filter-class>   <init-param>       <param-name>cors.allowed.origins</param-name>       <param-value>*</param-value>   </init-param>   <init-param>       <param-name>cors.allowed.methods</param-name>       <param-value>get,post,head,options,put</param-value>   </init-param> </filter> <filter-mapping>   <filter-name>corsfilter</filter-name>   <url-pattern>/*</url-pattern> </filter-mapping>

which think correct other cases i've seen here , on other sites.

my angular request looks this:

   private sendrequest(verb: requestmethod, url: string, body?: product): observable<product> {       let headers = new headers();       headers.set("withcredentials", "true");       headers.set("authorization", "basic ***********");       headers.set("access-control-allow-origin", "*");       headers.set("access-control-allow-headers", "origin, x-requested-with, content-type, accept");       headers.set("content-type", "text/plain");        return this.http.request(new request({         method: verb,         url: url,         body: body,         headers: headers       })).map(response => response.json());     }

so have couple of questions:

  1. what else have in configuring tomcat server send cors headers?
  2. am doing right things in request i'm sending?

update on thursday 24 august:

here headers , responses in web inspector network window (safari) when select row options method:

request & response: ==================== method:      options cached:      no status:      ___ code:        ___ encoded:     ___ decoded:     ___ compressed:  no  request headers: ================ name                            value user-agent                      mozilla/5.0 (macintosh; intel mac os x 10_12_5) applewebkit/603.2.4 (khtml, gecko) version/10.1.1 safari/603.2.4 cache-control                   max-age=0 referer                         http://localhost:4200/  origin                          http://localhost:4200 access-control-request-method   access-control-request-headers  authorization accept                          */*  response headers     no response headers

i've attached couple of screenshots. first shows request , response. second shows "preflight" error messages console i've mentioned above.

request , response details browser devtools

error messages logged preflight:

error messages preflight
