The error java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
is going to be covered in today’s post on Java.
What Is the java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
You may see this exception while implementing a Spring
MVC application to Servlet
containers because of the java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
, often in the spring-webmvc.jar
file, cannot be found.
In the Spring
MVC framework, the DispatcherServlet
intercepts all HTTP requests and routes them to the appropriate controllers based on URL mapping, which is the heart of the FrontController
pattern.
The Servlet
container and Spring
MVC framework rely on DispatcherServlet
to communicate. Servlet
containers must deliver or route all HTTP requests to the specified DispatcherServlet
, which has to be declared in your web.xml
and given a URL pattern.
Causes of java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
The following are examples of possible reasons for the exception.
-
Check to see whether the configuration file can be opened. If it cannot, you need to update the correct package name in the line that reads
<servlet-class></servlet-class>
in theweb.xml
file. -
At the time of Tomcat’s initialization, the required
Spring
MVC related.jar
files are not loaded and implemented. However, given these files are already in yourclasspath
, we’ll not experience any errors when using the Eclipse IDE to create the program.This only occurs when the program is executing.
Solution of java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
Although the right path to the package is opened, the path is not imported into the WEB-INF/lib
directory. The following is the particular solution to the problem.
-
To start, open the Eclipse IDE application and create a new project by the below steps.
From the left upper corner select
File
>New
>Java Project
, to create a new project.After creating a new project, name it.
-
Next, select
Properties
from the drop-down list that appears when we right-click on the project that we just created.
-
After that, select
Deployment Assembly
from the panel on the left of the screen. If you’re working onSpring
MVC, you will seeDeployment Assembly
.Otherwise, it will not appear on the list.
-
To specify the packing structure, click the
OK
button. -
There will appear a new window. Click
Add
and then chooseJava Build Path Entries
from the list. -
After selecting all of the
libraries
, click theFinish
button to complete the process. -
Click on
Maven Dependencies
on the new window to include all Maven’s.jar
files. -
You can now test your application by running it on Tomcat.
