I received the same error, I added to my pom.xml file the following lines and worked fine after maven install:

<dependencies>

        <!-- commons lang dependency -->
        <dependency>
            <groupId>commons-lang</groupId>
            <artifactId>commons-lang</artifactId>
            <version>2.6</version>
        </dependency>

</dependencies>

  • In my situation, my pom.xml already has `commons-lang` dependency, but the tomcat server in Eclipse still fails to start. I checked the "tomcat server's lib directory" and found no `dozer` jar there. So I copy a `dozer` jar from `.m2` directory to there, and the problem solved. – Hong Jul 28 '15 at 08:10
  • for sbt use: libraryDependencies += "org.apache.commons" % "commons-lang3" % "3.4" – Avision Sep 12 '16 at 10:33

In case you use maven and Ubuntu 14.04:

This can be caused by the maven version included in Ubuntu 14.04, and the workaround is to download the maven tarball from http://maven.apache.org/download.cgi and use that version instead of the default version provided by the distribution.

More information: https://github.com/airbnb/chronos/issues/211

EDIT: You can also add a symlink to commons-lang.jar to avoid having to do a custom install (Source and @Shoham in the comments)

cd /usr/share/maven/lib
sudo ln -s ../../java/commons-lang.jar .

Verify that the paths are correct on your system before attempting. They should work for Ubuntu 14.04 OOTB, but always verify.

    Thanks! Can also be fixed by 'cd /usr/share/maven/lib sudo ln -s ../../java/commons-lang.jar .' – Shoham Jul 27 '15 at 08:58
  • Wasted hours trying to fix all sorts of maven problems. Finally saw this answer. Removed my `~/.m2` directory, removed Ubuntu's `mvn` that I had installed via `apt` and then installed mvn afresh from http://mvn.apache.org. Everything works now! – nonbeing Aug 24 '18 at 17:50

Your code seems to be using apace-commons-lang package . Do add the jar from here http://mvnrepository.com/artifact/commons-lang/commons-lang/2.6. Chek for the version you are using. Add the jar to your lib folder/classpath.

Add the commons-lang jar either into WEB-INF/lib or server/lib

  • Hi,I have added commons-lang3-3.1, and Dozer jars to class path. But i'm still getting below exception: 15:22:52,730 SEVERE [ContainerResponse] The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container java.lang.NoClassDefFoundError: Could not initialize class org.dozer.DozerBeanMapper at com.ingenico.atlas.b2b.helper.DozerHelper.map(DozerHelper.java:13) – Amit Kumar Jul 22 '13 at 09:56
  • @AmitKumar Looks like you are missing something on the classpath. Seems a dependency of com.ingenico.atlas.b2b.helper.DozerHelper.map is missing, class org.dozer.DozerBeanMapper – mel3kings Jul 23 '13 at 01:15

I faced the same issue in latest version of IntelliJ Community Edition (idea-IC-13.224.1 or version 14) along with apache-maven 3.2.3.

Adding missing jar (commons-lang-2.6.jar) in $IDEA_HOME/plugins/maven/lib/maven3 folder seems to fix it.
