Spring Dispatcher Servlet Not Found Problem

Question

I'm trying to build a simple spring web application but I get the following error when I run it on Apache Tomcat 6.0

Class Not Found Exception org.springframework.web.servlet.DispatcherServlet

I'm using maven to handle libraries. At first I thought it was maven's fault but it adds spring and other libraries succesfully.

I tried to import "org.springframework.web.servlet.DispatcherServlet" in a source file and my project has the right package and classes.

My development environment :

Ubuntu 10.4 Eclipse IDE Tomcat 6.0

I'd appreciate any help

Answer 1

Make sure that your pom.xml is having compile time dependency like bellow

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>2.5.6</version>
            <scope>compile</scope>
</dependency>

Once project is build unzip your war file see it has required dependencies packaged properly or not in WEB-INF/lib

Answer 2

当我复制所有springwebmvc罐并粘贴在WEB-INF / lib文件夹中时效果很好.....

Answer 3

Check the deployment assembly from project properties. If maven dependecies is missing add that. Your deployment assembly should look like this

Answer 4

I added external jars thru java build path which were not reflected in web-inf/lib folder.so,the error occured.

I copied all those jars and pasted in the web-inf/lib folder and then my prob got solved.

Hope it helps.

Answer 5

If you can't find that class in WEB-INF/lib, the classloader won't either. Believe the JVM and assume that you (or Maven) has packaged or deployed it incorrectly.

Answer 6

您可能需要将spring下载的dist /内容和所需的链接包复制到web-inf / lib，然后再次尝试启动服务器
