Enunciate framework - Not working with Spring Restful project

I have integrated enunciate framework to generate the API document for the Spring RESTful project. I have followed the steps from https://github.com/stoicflame/enunciate/wiki/Executables and deployed the war created from the enunciate configuration in the tomcat server(http://localhost:8080/sample_enunciate) but its displaying the empty document. Here I have provided the configuration details used in the sample project.

NOTE: But the similar configuration is working with Jersey restful project. I really stuck here. Please let me know, is this bug with the enunciate framework integration with Spring project. Thanks in advance.

Project configuration:

java       -1.7.0
tomcat     -6.0 &7.0
ant        -1.9.4
spring     -4.0.5
enunciate  -1.30

jars:
