I have been struggling with this problem for a few days now (That is why I am providing GitHub link). Here is the stack trace:

    SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoadListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoadListener

I will point only, that I use Tomcat 7 and I run the server from Servers tab in Eclipse.

I have read everything in the Internet about it. The most common solution provided was:

"Go to project properties -> Deployment Assembley, click Add... , select Java Build Path Entries and add the Maven Dependencies to the Web Deployment Assembly."

And it does not work for me, same as other solutions in the Internet I have seen so far. I am hopeless.

I am providing GitHub link to my project: https://github.com/wiewioraseb/beer-blog-hiccup.git I already tried to export it to another computer, I still get the same error while running it on the other machine.

  • Sometimes cleaning tomcat resolves the Issue. And Do you see "Maven Dependencies" folder in your project libraries? Commented Mar 3, 2015 at 16:20
  • @SRy I have done that already unfortunately. I see Maven Dependencies in my project library. Commented Mar 3, 2015 at 16:38
  • can you post your project structure here? Commented Mar 3, 2015 at 16:42

  • For me your deployment assembly looks wrong. Maven project structure should be src/main/java. Check your deployment assembly looking like this google.com/imgres?imgurl=https://i.sstatic.net/…. And remove tomcat 7 library from classpath. Commented Mar 3, 2015 at 16:57

The correct listener class to bootstrap Spring root context is ContextLoaderListener, not ContextLoadListener! So in web.xml should be:

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

The link says: In deployment environment, just make sure your server classpath has included the Spring jar library (e.g spring-2.5.6.jar).

For Spring3, ContextLoaderListener is moved to spring-web.jar, you can get the library from Maven central repository.

<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-web</artifactId>
		<version>3.0.5.RELEASE</version>
</dependency>

Do you mean to copy spring-2.5.6.jar (or spring-web-4.1.5.RELEASE.jar) to C:\something\Tomcat7\lib directory? If not, where can I find server classpath?
But If OP exactly used the POM.xml whatever he copied from github link, he doesn't need to do anything. I suspect OP is missing some configuration.

Are you sure your build path (within eclipse) actually includes all the dependencies (in this case specifically spring-web und spring-webmvc)? If you build a *.war file, using mvn clean install, the libraries will probably be included in it, if you unpack it.

However, this is not the same as Eclipse. Therefore I suggest running mvn clean install eclipse:clean eclipse:eclipse within your directory. Then refresh the project in Eclipse and clean it as well (Project -> Clean).

To see if libraries are deployed properly, double click on your server and go to this location (in your workspace folder):

tomcat eclipse directory

and check for the dependencies (*.jar files) inside your WEB-INF/lib folder.

Generally this fixes the problem for me. You should:

  • close the server in Eclipse
  • rightclick -> clean -> clean Tomcat Work Directory
  • run the commands above
  • start the server

I made a .war file and unpacked it to check if the libraries are there. Everything is fine with it. I have already cleaned the directory, didn`t help ;(
I checked if the libraries are there: C:\something\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\beer-blog-hiccup\WEB-INF\lib and they are all in place. @Schaka
