No ClassDefFound Error while maven project is added as dependency to a non-maven in java

am trying to develop a Axis2 webservice. I created a dynamic web project to generate my webservice classes from WSDL. Once I implemented my logic in Skelton which has code to query to database.

All this database access logic is in another Maven built Project. I added this Maven build project as dependency in my webservice projectBuildPathto my webservice project which is not a maven built.

When I run this webservice and hit the service from Soap UI , I am getting No ClassDef Found Error as below.

[ERROR] com/sample/test/common/dao/PersonDAO
java.lang.NoClassDefFoundError: com/sample/test/common/dao/PersonDAO

My Webservice Code

     public class EnrollmentServiceSkeleton implements EnrollmentServiceSkeletonInterface{

            @Autowired
            PersonDAO personDao;   // Getters and Setters.

        public EnrollmentServiceRespMessage enrollmentServiceProfile (EnrollmentServiceReqMessage enrollmentService) {

// My WebService Logic
}

Is it the correct way that keeping a maven project as dependency to another non-maven directly in the build path of non-maven project?

Maven works by building a project but not building its dependencies into the package. Therfore the project that uses the library has the option to overide or exclude the maven depedencies.

When included in a non maven project you need to build it including dependencies.

See How can I create an executable JAR with dependencies using Maven? with details on how to do that.
