Hi all,
I was trapped in many error when i tried to create a new project used shindig's 
code.
There are many classes that my eclipse doesn't resolve such as:
org.json.JSONObject
com.google.common.collect.Multimap
org.apache.commons.io.IOUtils
...
I don't know what I miss.
Could you give some solutions, pls?
Thanks
