How to call a method on a ServletContext object?

Question

Java

Hello, in many examples I saw how the following code is present for the authentication filter settings

   private static boolean hasUrlPattern(ServletContext servletContext, String urlPattern) {
 
      Map<String, ? extends ServletRegistration> map = servletContext.getServletRegistrations();

But for some reason, when I create an object of the ServletContext class, I cannot find the given getServletRegistrations() method for it; , do not tell me how to get the necessary map, thank you

Answer 1

Solution found, I used too old versions

javaee-api

and

javax.servlet-api

the first one had a version below 8th and the second one had a version below 3rd,
if you change the dependencies in pom.xml to the following, then all functions will be found

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
        </dependency>
<dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-api</artifactId>
            <version>8.0</version>
            <scope>provided</scope>
        </dependency>
