Thank you, Solution 1: index.html page inside public, Solution 2: index.html page inside static. As you know, Java methods live in classes, so first create a Java class called WatchlistController.java underwatchlistpackage and add the @Controller annotation on top of it. This is all great, until you want to do some more advanced things. Parser So we like to request that if you can donate a small amount then will be more valuable to us.
