Setting Access-Control-Allow-Origin Header

Setting the Access-Control-Allow-Origin header value allows browsers to get responses from the origin and access it for the request codes sent.

The following is the procedure to set Access-Control-Allow-Origin header:

1. Open the web.xml file in an editor.
2. Search for the following tag:
   <filter>
   <filter-name>FilterServlet</filter-name>
   <filter-class>com.iflex.fic.filters.FilterServlet</filter-class>
   </filter>
3. Add the <init-param> tag values within the filterservlet tag as shown in the following:
   <filter>
   <filter-name>FilterServletAllowFrom</filter-name>
   <filter-class>com.iflex.fic.filters.FilterServlet</filter-class>
   <init-param>
   <param-name>AllowOrigin</param-name>
   <param-value><origin></param-value>
   </init-param>
   </filter>
4. Replace <origin> in the preceding tag with the URL of your website. This allows the request of code from the origin.
