DispatcherServlet Class Not Found Exception Again and Again

I have created a Spring MVC project where I used: jakarta 6.0 and spring-webmvc 6.2 in pom.xml Dynamic Web Module 5 JDK 23 I configured the Dispatcher Servlet in web.xml, then set up the View Resolver in spring-servlet.xml. After that, I created a Controller and placed index.jsp inside the WEB-INF/views/ folder. The server starts successfully, but I always get a 404 error: "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." Here is my console Output Attached too

So you are using Servlet 6 - then you'd probably want to use Dynamic Web Module 6 that should normally correspond to your servlet version check your web.xml for that - is there a verssion=5 maybe? that wouldn't solve your problem but it would be something off

Mohd Waqar Ahemed | ContributerOP•10mo ago

this is my web xml where the version is 6

dan1st•10mo ago

then you should use version 6 for Dynamic Web Module

dan1st•10mo ago

Anyway for your specific problem: https://stackoverflow.com/q/11227395/10871900 Note: The non Maven answers are probably not relevant

Stack Overflow

java.lang.ClassNotFoundException: org.springframework.web.servlet.D...

i am using spring 3.1.0.RELEASE, and my servlet container is tomcat 7 and my IDE is eclipse indigo and the jar spring-webmvc-3.1.0.RELEASE.jar which contains the DispatcherServlet exists in the lib

dan1st•10mo ago

For example one answer suggests adding Spring Context:

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>6.2.0</version>
    </dependency>

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>6.2.0</version>
    </dependency>

Mohd Waqar Ahemed | ContributerOP•10mo ago

okay i am adding it

dan1st•10mo ago

and make sure your dependencies are actually invluded with tomcat

dan1st•10mo ago

see https://stackoverflow.com/a/58838266/10871900
