I just presented my paper at WEB2013, The International Conference on Building and Exploring Web Based Environments, January 27 - February 1, 2013 - Seville, Spain
I found it very easy to be used especially for SoA. It makes it easy to build and deployed your projects to the server without any problems regarding to the configuration of the server. So, the benefits that I found are as following:
1- No needs to confiure the Weblogic server and SoA suite.
2- Fast start of the server.
