Content type Issue

I have a JSP page with content type set to
<%@ page contentType="application/vnd.ms-excel"%>. I also have some javascript code in it, but seems it is not working. Can I have script inside a JSP page of this kind?

Since i have set the content type, the page asks for "open or save dialog". I want to close the parent window (the IE) on clicking "save". However, the "open" option is working fine. Is it also possible to prevent the dialog-from getting displayed, and simply bypass to "open" option.

Please do not crosspost. Thank you
