Certainly not. The effort is to implement the axis2 architecture in C.

I am definitely +1 to move current 1.x C++ code to more OO and cleaner 
C++. However, if we are to convert current Axis C++ architecture into 
Axis2 architecture, it will be a nightmare, given the amount of changes, 
hence a re-write in C to realize Axis2 in C.
Axis C++ 1.x family would continue to live and be improved independent 
of this Axis2 effort.

Your comments are taken positive and are very much valuable. We 
certainly value the contributions you made by taking time to review C++ 
code and comming up with fixes. Many thanks for that.
