Re: MLHttpRequest cannot load

[Shashank Dutt Jha]

I added following code: Still facing issue

@CrossOriginResourceSharing(
        allowOrigins = {
           "http://localhost:56696";
        },
        allowCredentials = true,
        maxAge = 1,
        allowHeaders = {
           "X-custom-1", "X-custom-2"
        },
        exposeHeaders = {
           "X-custom-3", "X-custom-4"
        }
)

@Path("/office/")
public class OfficeOffice {
int count = 0;
Object obj = new Object();
@Context
private HttpHeaders headers;

@GET
@CrossOriginResourceSharing(allowOrigins = { "http://localhost:56696"; },
allowCredentials = false, exposeHeaders = {
"X-custom-3", "X-custom-4" })
@Path("/offices/{id}/")
@Produces("text/plain")
public String getCustomer(@PathParam("id") String id) {
synchronized (obj) {
++count;
System.out.println("----invoking getCustomer, Customer id is: " + count);
}
return "Systems";
// return Response.status(Status.OK).entity("works").build();
}

// This method will do a preflight check itself
    @OPTIONS
    @Path("/")
    @LocalPreflight
    public Response options() {
        String origin = headers.getRequestHeader("Origin").get(0);
        if ("http://localhost:56696".equals(origin)) {
            return Response.ok()

 .header(CorsHeaderConstants.HEADER_AC_ALLOW_METHODS, "DELETE PUT")

 .header(CorsHeaderConstants.HEADER_AC_ALLOW_CREDENTIALS, "false")

 .header(CorsHeaderConstants.HEADER_AC_ALLOW_ORIGIN, "http://localhost:56696
")
                           .build();
        } else {
            return Response.ok().build();
        }
    }

    @GET
    @CrossOriginResourceSharing(
         allowOrigins = { "http://localhost:56696"; },
         allowCredentials = true,
         exposeHeaders = { "X-custom-3", "X-custom-4" }
    )
    @Produces("text/plain")
    @Path("/annotatedGet/{echo}")
    public String annotatedGet(@PathParam("echo") String echo) {
        return echo;
    }
