Displays a preview frame for report defined in the file specified by urlname. The contents of the url are parsed and the report is fed into a new PreviewPane. The given TableModel is assigned to the report as report data source.

If the report contains external references in specified in relative urls, the urls are loaded using the reports parent directory as content base.
