How to list all the folders in BO 4.1 using java SDK ?

Hi,

     I have to list all the folders of Universes and Reports in the repository. I have found that all the reports in BO will store under Report folder 23 and Universes will store under Root folder 95. I don't know how to loop through all the folders. Can anyone help me to achieve this. Thanks in Advance !!

Thanks,

Kamalessh.
