The example for updating Data Extensions in "[Developing ExactTarget app in JAVA SDK](https://salesforce.stackexchange.com/questions/34088/developing-exact-target-app-in-java-sdk)" was what I have been looking for. Unfortunately, I'm not able to get it work for Shared Data Extensions.

I've tried using the `ENT.` prefix on the name with no luck. I've tried including the folder name beneath the Shared Data Extension folder in the name (Like `ENT.subfoldername.deName`) with no luck.

Is there a trick I am missing?
