tomcat - getting error when making a post request in ionic angular -


i new ionic3 , jaxrs guide me in correct way learn

    @post     @path("example1")     @consumes(mediatype.application_json)     @produces(mediatype.application_json)     public list<dairydto> gettodaydairyforparents(employeedto employee) {         emplist = employeedao.getrecords(employee.getname());       return emplist ;     }

this working fine in postman

but when made post request

let employee = new urlsearchparams(); employee.set('name', "ram");  this.http.post('http://localhost:8080/sms/webapi/test/example1', employee, {             headers: headers         }).map(res => res.json())       .subscribe(data => {         // we've got raw data, generate core schedule data         // , save data later reference         this.data = data;         resolve(this.data);       });  getting errors

xmlhttprequest cannot load localhost:8080/restexample/webapi/test/example1. response preflight request doesn't pass access control check: no 'access-control-allow-origin' header present on requested resource. origin localhost:8100' therefore not allowed access. response had http status code 403.

filters used in tomcat

<filter>   <filter-name>corsfilter</filter-name>   <filter-class>org.apache.catalina.filters.corsfilter</filter-class> </filter> <filter-mapping>   <filter-name>corsfilter</filter-name>   <url-pattern>/*</url-pattern> </filter-mapping>

you trying communicate http://localhost:8080/ using xmlhttprequest localhost:8100 not allowed default. server should trust localhost:8100 adding access-control-allow-origin response header:

access-control-allow-origin: http://localhost:8100

you should configure apache corsfilter parameters according access policy need.
