ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet. Having the required jars

Question

I know this question has been asked already, but none of the solutions actually helped me. I'm still getting this exception. I've tried everything, checked Maven Dependencies in "Deployment Assembly", did Maven clean and install, moved my project from user directory to another directory, re-installed the tomcat server, re-created the project. The class "DispatcherServlet" is inside Spring-webmvc, which I've included in my Pom.xml.

Here are my files:

Dependency scope is mentioned as provided . Check this question to understand the difference between compile and provided. You might have to use compile scope, if your tomcat installation doesn't have the required spring jars.

Adding spring-webmvc should be enough!

spring-beans content is also in the spring.jar. spring-webflow you only need if you also use/intend to use Spring Web Flow, if you didn't need it before then you shouldn't need it now....

spring-beans - 2.5.2
spring-webmvc - 2.5.2
spring-webflow - 1.0.5
spring - 2.5.2

As you can see in the pom.xml, the dependency is there. It's there in the build path too, I've verified. Still clueless what is the cause for that. – Amrit Kr Lama Apr 10 '18 at 07:19
Most probably the necessary Spring MVC related jar files are not loaded and deployed on tomcat startup. But note: these files are in your classpath and hence you are not getting any error in Eclipse IDE during development time. Happens only during runtime – Mahendra Sri Dayarathna Apr 10 '18 at 10:22
And the probable solution would be? – Amrit Kr Lama Apr 10 '18 at 11:12
You can see DispatcherServlet declaration in deployment descriptor or web.xml file as below: – Mahendra Sri Dayarathna Apr 11 '18 at 18:19

For Spring mvc and hibernate only spring-mvc ,hibernate-core and hibernate-entity dependencies are enough. I Believe, you are using Hibernate ORM framework in this project. Spring framework provides support to integrate with third-party ORM frameworks like hibernate ORM.

<!-- Spring ORM support -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-orm</artifactId>
        <version>${spring-framework.version}</version>
    </dependency>

If you are performing transaction then spring provide below dependecies to achieve same.

<!-- Spring and Transactions -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring-framework.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>${spring-framework.version}</version>
    </dependency>

Please try adding these dependencies in your pom.xml

<properties>
    <java-version>1.6</java-version>

Actually, I've not reached till any Transaction part. I've created just 2 jsp pages and I'm trying to move from one to another. While running the project itself, this Exception is coming up. — Amrit Kr Lama, Apr 10 '18 at 07:43
I think you can try with dependencies that I have provided, at least you can test issue remains same or it resolved right. If it is not then provide me link from where you got code so that i can have a look. — Ramesh Fadatare, Apr 10 '18 at 08:20
