[news.eclipse.technology.cosmos] How to creating a Data Manager

["Jennifer" <zengjin3664@xxxxxxx>]

Hello£¬
I am trying to follow the instructions of creating a Data Manager in the
Developer's Guide. I also read COSMOS Installation Guide and COSMOS User's 
Guide.But here are some problems.

When I point my web browser to display the COSMOS Web User Interface,the 
Data Manager Navigator is loading Data Managers all the time.At the same 
time,the Console displays the error information as follows:
Serious: Servlet.service() for servlet json threw exception
java.lang.ClassNotFoundException: org.apache.axis2.AxisFault
