How to define CORS in Websphere Application Server Liberty Profile V8.5

Question

Is it possible to apply cross-origin resource sharing (CORS) in a Websphere Application Server Liberty Profile V8.5 ?

I searched the redbook but couldn't find IBM mention anything about it. (http://www.redbooks.ibm.com/abstracts/sg248076.html?Open)

It's not possibility for me to set the headers programmatically like this:

Access-Control-Allow-Origin: *

You have to add following jars to your WEB-INF/lib folder:

• cors-filter-1.8.jar
• java-property-utils-1.9.jar

In your web.xml you have to add following rules:

<filter>
    <filter-name>CORS</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
</filter>
<filter-mapping>
        <filter-name>CORS</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
