exact target web service error for data extension

I am hav开发者_JAVA技巧ing a problem when trying to connect to EXACTTARGET web service and upload the data from the database to the DataExtension. That is what I have, I do have a method called getData() this works fine. I have bolded the line that brings back an error in the string uStatus.

I solved it. I needed a primary key on my data extension to match the information i was sending over.
