The functionality to show a (nested) list of models is available through
http://[machine]:[port]/itp/app/[application]/listmodels.aspx
(http://[machine]:[port]/itp/app/[application]/listmodels)
A call to listmodels will result in two HTML pages, one automatically loading the other. The first page shows a nested list of folders. The latter is loaded in the Model List Frame and shows a list of models for a selected folder in the list of folders.
Because of this it is wise to provide a frameset, which contains a frame with the name configured as the Model List Frame. This can be done in the modelselect page, which is available through:
http://[machine]:[port]/itp/app/[application]/modelselect.aspx
(http://[machine]:[port]/itp/app/[application]/modelselect.jsp)
See ITP/Server: OnLine exit points for more information on the way the list of models is retrieved from ITP/Server.
