I’m making jira API calls in javascript  and  I’m getting CORS errors due to origin null.I added below filters to web.xml but it’s not working.

<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>

Here is error :

Access to XMLHttpRequest at 'http://Host:8080/ url' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
