How to fix HTTP Status 404 Error while running Spring MVC project?
I have been running Spring MVC projects since last ~8 years and created numerous professional and personal project in Java and Spring MVC combination.
On Crunchify we have more than ~50 Spring MVC tutorial for you to use for free. Today while running my old Hello World Spring MVC tutorial I got below error message while starting Tomcat in Eclipse IDE.
Jul 20, 2016 2:12:20 PM org.apache.catalina.core.StandardContext loadOnStartup SEVERE: Servlet [crunchify] in web application [/CrunchifySpringMVCTutorial] threw load() exception java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1308) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1142) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:518) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:499) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:118) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1102) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:1038) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4997) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5289) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:147) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1408) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1398) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
Why this exception happened:
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.
How to fix this?
Step-1
- Right click on project
- Click on
Properties
Step-2
- Click on
Deployment AssemblyTab in the left - Click
Add...
Step-3
Click on Java Build Path Entries
Step-4
- Click on
Maven Dependencies - Click
Finishbutton
Step-5
- Redeploy Spring MVC application to Tomcat again
- Restart Tomcat
- Try accessing URL again and you shouldn’t see any error now
Sao tui add thư viện maven rồi nhưng lỗi vẫn xảy ra ?

Hi Ravip – did you try cleaning your worksspace and building your project again? Try following this tutorial: https://crunchify.com/mavenmvn-clean-install-update-project-and-project-clean-options-in-eclipse-ide-to-fix-any-dependency-issue/
After i tried this way, got this exception.
Please help my issue. Thank u in advance.
Hi Sarjita – are you using Java9? You may face this issue with Java SE9. Also, try adding below dependencies to your project in pom.xml file.
javax.xml.bind jaxb-api 2.2.11 com.sun.xml.bind jaxb-core 2.2.11 com.sun.xml.bind jaxb-impl 2.2.11Let me know your result when you get a chance.
Really nice article.
Could you, please, help me in case of Gradle use? When I see the window “Java Build Path References”, it’s totally empty and there is nothing to apply.
How to proceed?
Hi Julia –
Can you please share your screenshot? I would like to debug it further.
Hello! Thanks for your tutorial and this post.
I implemented it and fixed my initial error with ClassNotFound,
but in the console there is still this warning:
Sep 23, 2017 8:17:14 PM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/CrunchifySpringMVCTutorial/] in DispatcherServlet with name ‘crunchify’
and my application keeps throwing 404 🙁
Could you help me?
Hi Sabrina Perardt –
Error shows you have some conflict with servlet-name and servlet-class. Make sure to take a look at Spring MVC tutorial.
I tried all things but I can not succeed.
Hi Harsh – it’s complaining about nDMS. What is it?
Thanks
You are most welcome Krishna.
Thank you soo much!!!!!!
You are welcome Mansi. Happy coding.
When I click on Java Build Path Entries and click Next, it does not show Maven dependencies. It just shows a empty box where there is nothing to select. How can I fix this?
Thanks.
Hi Kumar – is your project a Maven Project? If yes, you could see maven dependency. If not, you could convert it by following this tutorial: https://crunchify.com/how-to-convert-existing-java-project-to-maven-in-eclipse/
Also, would be nice if you share your Eclipse project structure screenshot.
Hope that helps.
Yes my project is Maven Project but I cannot see the Maven dependencies. My project structure is as follows. Screenshot.
Thanks for sharing screenshot Kumar. Dependencies should be under /target folder.
try following this tutorial and errors should go away: https://crunchify.com/mavenmvn-clean-install-update-project-and-project-clean-options-in-eclipse-ide-to-fix-any-dependency-issue/
thanks
