Jetty Cross Origin Filter

Aloha,

I fought this for awhile as well, and found that the final node needs to be:

<filter-mapping>    <filter-name>cross-origin</filter-name>    <url-pattern>/*</url-pattern></filter-mapping>

NOT

<filter-mapping>     <filter-name>cross-origin</filter-name>     <filter-pattern>/*</filter-pattern></filter-mapping>

Here is the link I found to help me: wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter

After I updated my web.xml file and restarted the jetty server, I was able to make cross domain request using jQuery ajax calls.

I ran into this when doing crossdomain calls to web apps deployed to GAE. You can add an explicit header to your Servlet(s) responses, like:

public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {    res.addHeader("Access-Control-Allow-Origin", "*");    ...}

and also make sure you have a crossdomain.xml policy file in the root of your WAR, like:

<cross-domain-policy xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:noNamespaceSchemaLocation="http://www.adobe.com/xml/schemas/PolicyFile.xsd"><allow-access-from domain="*"/></cross-domain-policy> 

HTH.

I had the same Problem with ActiveMQ Ajax within Jetty Web Server. My Problem was, that the allowed headers field is not accepting a wildcard in form of "*".

For getting ActiveMQ Ajax to work, i also have to add the "Options" Method to the allowedMethods.

Cross-Origin Filter from web.xml:

<filter>   <filter-name>cross-origin</filter-name>   <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>   <init-param>       <param-name>allowedOrigins</param-name>       <param-value>*</param-value>   </init-param>   <init-param>       <param-name>allowedMethods</param-name>       <param-value>GET,POST,OPTIONS,DELETE,PUT,HEAD</param-value>   </init-param>   <init-param>       <param-name>allowedHeaders</param-name>       <param-value>origin, content-type, accept, authorization</param-value>   </init-param> </filter> <filter-mapping>     <filter-name>cross-origin</filter-name>     <url-pattern>*</url-pattern> </filter-mapping>
