Jari,
thanks for looking at my problem.
I have looked at the servlet API and it doesn't really help me
identify a clear offender in my code.
I don't set the "type" more than once in my responses, at least
I don't think that I do...
I will show you the flow of events that lead up to the problem:
1. JSP page renders to a browser. The resulting HTML page
contains links that point to another JSP page in the
following manner:
<a href="test2.jsp?objectID=123">Attachment one</a>
2. The user clicks on one of the links to initiate the download
process.
3. The "test2.jsp" page takes the passed object ID and pulls
the EJB object out of the database and puts the object in
the user's session. After this is done in the "test2.jsp"
page it sends a redirect, response.sendRedirect(), to my
servlet.
4. The servlet actually performs the getOutputStream() command,
and streams the binary content of the object to the browser.
I am under the impression that since I did a
response.sendRedirect() in step 3, that step 4 is dealing
with a completely new response.
5. The download actually works, but the hourglass keeps twirling
in my original window, leading me to the conclusion that something
went awry. Additionally, there is no error generated by my compiled
JSP servlet leading me to believe that the JSP engine, JRun in my
case, is calling a getOutputStream() or a getWriter() outside of my
compiled JSP page, and after my servlet has executed...
6. Finally, the compiled JSP page does perform a
JspWriter out = pageContext.getOut();
but that shouldn't cause any problems.
Thank you for taking the time to look at this, I look forward to
hearing from you again.

Cor,
have you checked the servlet documentation for a lead on this?
I had this problem writing servlets - basically you can only call
getOutputStream and set it's "type" once - if it gets set to "text/html"
before you want to write binary data to it, then you're screwed (to use
the technical term ;)
Have a look in the servlet api at the getOutputStream call, then try
looking at any generated java code for your jsp pages.
