It looks like there is the RemoteServiceServlet being called by
the RequestBuilder. That can't work you have to call the original
servlet or do that inside a RemoteServiceServlet and pass the data
through. BTW:
response.setContentType("application/ms-excel");
response.setContentLength(8100);
PrintWriter out = response.getWriter();
String htmlString = new String("<HTML>" +
"<TABLE cellspacing=1 cellpadding=1 border=1> " +
This is not an Excel-format.

My favorite way is define an Iframe on the base-page of the
GWT-application that I access inside the java-class and set
the source of the iframe using DOM. That way you can call
the servlet directly and the browser should behave the same
way like you're used to in the good old JSP-times.
