Cross BrowserError.txt

Sample Code:


@Path("/messages")
public class MyMessage {
	@GET
	@Produces(MediaType.APPLICATION_JSON)
	public Response NewMethod() {
		String output = "Hello World";
		 return Response.ok(output) //200
				.header("Access-Control-Allow-Origin", "*")
				.header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT")
				.allow("OPTIONS").build();
			  }
}

Where,
/messages represts url like: http://localhost:8080/Jersey/webapi/messages


ReturnType should be response of the method and the string that we need to output is stored in the output variable/
.header is required and inseted of * we can also speccify the path like url as above other things will remain same

Alternate Way:

INCLUDE THIS CLASS:

@Provider
public class CORSFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext request,
            ContainerResponseContext response) throws IOException {
        response.getHeaders().add("Access-Control-Allow-Origin", "*");
        response.getHeaders().add("Access-Control-Allow-Headers",
                "origin, content-type, accept, authorization");
        response.getHeaders().add("Access-Control-Allow-Credentials", "true");
        response.getHeaders().add("Access-Control-Allow-Methods",
                "GET, POST, PUT, DELETE, OPTIONS, HEAD");
    }
}
And in the web.xml add the following lines

		<init-param>
  			<param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
  			<param-value>com.message.data.CORSFilter</param-value>
		</init-param>
