An error occurred: An error occurred while trying to view the document

Now my partner meet a trouble about opendocument API.

There are 2 servers : one is partner’s web server ,which partner’s application run in; other is BO server.

The above servers are running on different servers.

There is a web page A , which is running in partner’s web server.

Page A includes a iframe, whose source is BO documents running in BO server via opendocument API.

In Chrome, the page A work.

But in IE, the page A don’t work, then get the error “An error occurred: An error occurred while trying to view the document”

You can see error.jpg

I have written the sample page to re-produce this error.

You can change 1.txt to 1.jsp

Welcome your advice.
