rdoc“e5ntxô›´Êd Error - Not a viewable document

This is a Tango application file.

It is usable only by the Tango Application Server.

You are probably seeing this message for one of the following reasons:

You are trying to load the application file directly instead of specifying it as a path argument to Tango.
Use the correct URL syntax.
You are using the <@INCLUDE> tag to include it in result HTML.
You cannot do that because this is not an HTML document.
(Macintosh only) Your WebSTAR action for Tango is set up incorrectly.
Consult your WebSTAR documentation.
