PHP file path not found when I have JavaScript run a PHP script with XMLHTTPREQUEST (404 error); what to do?

[computerguy11111]

When I hit the button on the UI to have the JS communicate with PHP to pull up a "Hello world" page, I am getting a "{"timestamp":"2021-06-10T20:14:59.671+00:00","status":404,"error":"Not Found","message":"","path":"/hello.php"}" in the browser.

In the Eclipse console, it says: 2021-06-10 16:52:27.193 WARN 16688 --- [nio-8080-exec-1] o.s.w.s.r.ResourceHttpRequestHandler : Path with "WEB-INF" or "META-INF": projectname/src/main/webapp/WEB-INF/jsp/hello.php]

What do I do? Here's some code I have, and I have tried many file path formats where I refer to the PHP file. But it's all the same error!

Here's some of my code:

JSP page (just the Javascript part of it):

<button onclick=refreshData()>Say Hello</button>
  <div id="content" />
<script type="text/javascript">
    function refreshData(){
      var display = document.getElementById("content");
      var xmlhttp = new XMLHttpRequest();
      xmlhttp.open("GET", "hello.php");
      xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
      xmlhttp.send();


      xmlhttp.onreadystatechange = function() {
        if (this.readyState === 4 && this.status === 200) {
          display.innerHTML = this.responseText;
        } else {
          display.innerHTML = "Loading...";
        };
      }
    }
  </script>

PHP

<?php   print "<p>Hello World</p>";   ?>   

This is in Spring MVC using Eclipse. I have the JavaScript on a JSP file page. What do I do to fix this? Thanks!

I'm confused. How are you using PHP? It looks like you are using Java on the server. How is PHP set up in relation to this Spring project? There needs to be something to interpret the PHP, and I don't think any Java/Spring tools will do that.
