Apache CXF Helpful materials for NewBie / Because org.springframework.beans.factory.BeanCreationException:
Error creating bean with name
Dear All,
I have recently started the development of Restful web services with Apache
CXF/Spring. Its a little bit difficult for me to configure the requisite
config files even for a *HelloWorld Program*.
*Here is my Dir Structure*
src/main/java/com.esumit.all/SimpleQAImpl.Java
resources - empty

---------------------------------
- I totally understand that this program is doing even basic mistakes, may
you please suggest me how to understand teh basic concepts and apply here
to make this even basic 'helloworld' program work ?
Questions -
1. Do we need to add the Spring ApplicationContext file ?
Thanks for everything,

I figured out the problem, thanks for reading it , Its kind of solved, I
would write additional question if any soon. Certain changes in
ApplciaitonContext.xml, URL Patten, and annotations on Service helped.
This Link actually helped :

Thanks
