Here is how you can make a call to a server for a set of folders and display them in a window.
1. Define a named dataset pointing the http xml service you have
2. Get a window with width
3. Write multiple lines with each line representing a folder
1. Datapath
2. Dataset
3. Simplelayout
4. Repeated views based on a datapath setting
<canvas height="120">
<dataset type="http" name="foldersDataSet"
request="true"
src="http://216.187.231.34//akc/display"
querystring="url=ShowFiledReportsViewJSPURL&ownerUserId=satya&aspire_output_format=object-xml"/>
<window width="200">
<simplelayout spacing="5" axis="y"/>
<view datapath="foldersDataSet:/AspireDataSet/FoldersLoop1/row">
<simplelayout spacing="2" axis="x"/>
<text>+</text>
<text datapath="folder_name/text()"/>
</view>
</window>
</canvas>
