Java - 404 after deploying servlet to Glassfish

I'm pretty new to servlets in Java and i was trying to deploy the following servlet with this GET method:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    response.setContentType("text/html");
    out.println("");
    out.println("
Welcome!
");
    out.println("");
}

I checked the console and it was deployed successfully, no errors. However, when i open my browser and go to:

http://localhost:8080/web1/AddPassenger

I get the HTTP Status 404 - Not Found error.

What could be the problem?

EDIT: Content of glassfish-web.xml:





    /Web1

Solved

I'm not sure what was the problem, but i installed a new version of Eclipse (Oxygen, i used Mars before that) and it worked!

Many thanks to everyone for their help!

How to declare a custom class in google scripts?

I want to create a class inside my script. Google Apps Script language is based on javaScript, so I took an example from a javaScript manual: class Polygon { constructor(height, width) { this.height = height; this.width = width; } } However, this doesn't work. I get this error message: Missing ; before statement. (line 1, file "Code") Does that mean it's not possible to create new classes in google scripts? Or is there a different syntax I'm supposed to use? Solved Historically Javascript is a "classless" language, classes are a newer feature which haven't been widely adopted yet, and apparently are not yet supported by Apps Script. Here's an example of how you can imitate class behaviour in Apps Script: var Polygon = function(height, width){ this.height = height; this.width = width; this.logDimension = function(){ Logger.log(this.height); Logger.log(this.width); } }; function testPoly(){ v...

Does Instance Variables of a module shared between class with the mixin?

I want to know how the instance variables of a Ruby module behaves across multiple classes which 'mix' it 'in'. I wrote a sample code to test it: # Here is a module I created with one instance variable and two instance methods. module SharedVar @color = 'red' def change_color(new_color) @color = new_color end def show_color puts @color end end class Example1 include SharedVar def initialize(name) @name = name end end class Example2 include SharedVar def initialize(name) @name = name end end ex1 = Example1.new("Bicylops") ex2 = Example2.new("Cool") # There is neither output or complains about the following method call. ex1.show_color ex1.change_color('black') ex2.show_color Why it doesn't work? And Could someone explain what will the actual behavior of @color across multiple Example$ instances? Solved In Ruby modules and classes are objects, so it's possible to se...
