mapping user and home folder

Hi all,

In PI 7.0 - in graphical mapping, i am writing a UDF and java class to write a file in PI file server. In the code for writing the file i have not mentioned any path.

My understanding is - the file will be written in the home folder of PIISUSER as PIISUSER is the user that XI uses to access mapping runtime. Is my understanding clear...if not please clarify
