java.lang.NoClassDefFoundError on Maven multi module project using Spring

Question

I work on a maven multi module project with submodules. I use Spring and Spring MVC

 <modules>
   <module>web</module>
   <module>business</module>
   <module>integration</module>
   <module>persistence</module>
   <module>common</module>
   <module>logging</module>
</modules>

I want to get data from my view to controller using Jackson

@RequestMapping(value = "registerAgency", method = RequestMethod.POST)
public final String 
registerAgency(@RequestBody final RealEstateAgency realEstateAgency) {

//doSmth();
return "index";
}

My controller is in my web module and my RealEstateAgency class is in common module When I run my project I get the following errors

javax.servlet.ServletException: Servlet.init() for servlet dispatcher threw exception

You probably just need to add a dependency on your common module to your pom.xml in your web module

It is done. There are dependencies between modules. The problem is in @RequestBody. When I don't use it there are no exceptions – Oleh K Feb 03 '16 at 16:15
Maybe you have some static initialization in your `RealEstateAgency` class that is throwing an Exception? – heenenee Feb 03 '16 at 16:18
Also, when you build, make sure you're doing a `mvn clean install` from your top level project to ensure that your `web` module is pulling the most recent version of your class from the `common` module. – heenenee Feb 03 '16 at 16:20
