Hello,
I try to execute Spark-submit from Angular post http and given problem CROS:

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://185.28.5.2:4200' is therefore not allowed access.

Any help plaise

@JavaSparker no problem with the following configuration

            BasicConfigurator.configure();
	
	Spark.staticFiles.location("/assets");
	Spark.staticFiles.header("Access-Control-Allow-Origin", "*");
	
	options("/*", (req, res) -> {
		String accessControlRequestHeaders = req.headers("Access-Control-Request-Headers");
		if (accessControlRequestHeaders != null) {
			res.header("Access-Control-Allow-Headers", accessControlRequestHeaders);
		}

		String accessControlRequestMethod = req.headers("Access-Control-Request-Method");
		if (accessControlRequestMethod != null) {
			res.header("Access-Control-Allow-Methods", accessControlRequestMethod);
		}

        return "OK";
	});

	before((req, res) -> {
		res.header("Access-Control-Allow-Origin", "*");
		res.header("Access-Control-Allow-Headers", "*");
		res.type("application/json");
	});
