Tomcat中的CORS支持通过过滤器提供。您需要将此过滤器添加到您的web.xml文件并配置它以满足您的要求。有关可用配置选项的完整详细信息，请参见 Tomcat文档。 / p>

I am trying to consume some web services which are cross domain. When I disable chrome's web-security it is working fine. I want it to work without this so I have tried adding cross-domain.xml and still it didnt work. When i searched more, came to know about CORS enabling in tomcat.

from www.w3/wiki/CORS_Enabled

For Apache Apache can be configured to expose this header using mod_headers. This is enabled by default in Apache, however you may want to ensure it's enabled in your deployment by running the following command:

a2enmod headers

To expose the header, you can add the following line inside , , and sections, or within an .htaccess file.

<IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" </IfModule>

Can anyone please let me know where to add these configurations in TOMCAT and in which files exactly. I am using tomcat from eclipse.

Appreciate any help.

CORS support in Tomcat is provided via a filter. You need to add this filter to your web.xml file and configure it to match your requirements. Full details on the configuration options available can be found in the Tomcat Documentation.
