Solution
You can download the library here – http://sourceforge.net/projects/dom4j/files/dom4j/
Or
Add the dependency in Maven’s pom.xml
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>
What is Maven’s pom.xml?
You mean it web.xml.
I dont have any pom.xml in my project
Would somebody get in touch with whoever makes the maven packages and tell them to get their dependency act in gear?
