Hi,

I am wrote a programm which analyses websites. I extended the project
to support javascript as well. For that I included the rhino library.
My HTML Parser is able to get the javascript code out of the html code
and can execute that code using rhino. But most javascripts are
throwing an error each time they use code like:
--------------------------------------------------------------------------
                if ((top.window.opener == null) ||
                        (top.window.opener.closed==true) ||
                        (top.window.opener.su == null)){
                        top.su = su;
                } else {
                        top.window.opener.su = su;
                }
--------------------------------------------------------------------------
It seems that the Object "top" is not defined and "top" is something
like an allways accessable object for IE/NETSCAPE/... but not for
rhino

Now my question. How can I manage, that all of such scripts are
working? Yes I now, that setting object like window/top and so on does
not change anything at my application.

Here is the complete java stacktrace:
--------------------------------------------------------------------------
