JasperServer blocked by CORS policy: No 'Access-Control-Allow-Origin' - apache

Question

I'm trying to enable CORS policy in the jasperserver.
I'm using angular HTTPClient to call the API coming from the jasperserver.
Things that I have tried so far.
Modifying the apache-tomcat apache-tomcat\conf\web.xml file
and addding the code below.
<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.headers</param-name>
<param-value>Content-Type,X-Requested-With,Accept,Authorization,Origin,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
</init-param>
<init-param>
<param-name>cors.exposed.headers</param-name>
<param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>
which is from the apache-tomcat site.
Also tried to modify the jasperserver\WEB-INF\Web.xml file
and adding the code below
<filter>
<filter-name>CorsFilter2</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>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
And still no luck and encountering this error.

After struggling for a couple of hours with this, i have it figured out.
You have to disable Jasper's built in CorsFilter altogether, along with adding/mapping your own filter in your tomcat's /webapps/jasperserver/WEB-INF/web.xml. No intervention is needed in the global tomcat web.xml.
<!-- Comment the built-in filter out.
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>com.jaspersoft.jasperserver.api.security.csrf.CorsFilter</filter-class>
</filter>
-->
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.origins</param-name>
<!-- Tomcat 8.5+ doesn't allow '*' any longer in conjuction with 'cors.support.credentials' set to true.
Instead, a specific comma separated list has to be set here. See https://bz.apache.org/bugzilla/show_bug.cgi?id=62343 -->
<param-value>http://localhost:9000</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.headers</param-name>
<!--- If requests contain an authorization header, it has to be added here as well -->
<param-value>
Content-Type,X-Requested-With,Accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers,X-Remote-Domain,Authorization

<!-- Ensure your newly introduced mapping is first in line -->
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>

<!-- Also comment out any existing mappings for the built-in filter -->
