Creating Web Service Using Axis2(Servlet.init() fir servlet AxisServlet threw exception)

When i tried to create Web Service using Axis2, i successfully get the Apache welcome page. But when i click the Services i got error like below,

I solve this by downloading xmlschema-core-2.2.1  and copy the xmlschema-core-2.2.1.jar file inside the lib folder and paste it to the project WebContent/WEB-INF/lib. Then right click --> Build path --> Configure Build Path

Then the Servlet.init is gone.
