Last night, I figure out what the problem is. In Eclipse, I define a user library named axis2 including all the jar's in the bin directory. An option for the user defined lib is the "system library (add to the boot class path)". I am not sure how this system library works. When I create the axis2 lib as a system library, the exceptions will come out. However, if the axis2 lib is not a system library, all the thing are OK. It seems that it is related to class loading as you said.
Thank you,
Don
