JSP XML output to file system

Question

I hava a JSP application that uses the XDK to query the database and display XML rowset data to a JSP. This rowset data can be a few hundred rows or up to 50,000 rows,
as we publish technical manuals, parts manuals and wiring manuals for aircraft.
Getting the data to display within the JSP is not a problem. The problem is
that the XML rowset data shares two purposes:
1. Query by Example, returning
XML formatted data for display within a browser.
2. Use of the XML formatted
data as an external entity file for our SGML authoring software to print the
paper publication.
The JSP I developed (I'm not sure I should take credit for it) uses the XMLData bean and it will open the browser File/SaveAs dialog in both Netscape (Unix) and IE5.5 (Windows). HOWEVER, when I create a second JSP to perform the same task on a different table the JSP errorpage shows with no error and no errors within the JDeveloper console. This has been kicking my butt for some time, and would very much appreciate a workable solution. I will share whatever I can share with the provider. Here is the JSP code.
=============================================
<?xml version="1.0"?>
<%@ page language = "java" errorPage="errorpage.jsp" import = "java.io.*, java.util.*, oracle.jbo.*, javax.naming.*, oracle.jdeveloper.html.*, oracle.jbo.html.databeans.*" contentType="text/html;charset=ISO-8859-1" %>
<jsp:useBean class="oracle.jbo.html.databeans.XmlData" id="h25EqXml" scope="request" >
<%
h25EqXml.setResultElement("equiptbl");
h25EqXml.setReleaseApplicationResources(true);
h25EqXml.setDisplayAttributes("Ein,Pnr,Nomen,Cage,Diagnbr,Sht,Effect");
h25EqXml.initialize(pageContext,"h25Wires_JspApp_h25Wires_be_H25Wires_beModule.HU25A_Equipment");
response.setContentType("text/sgml");
response.setHeader("Content-location","attachment;filename="+"equiptbl.sgm");
ServletOutputStream sos = response.getOutputStream();
BufferedInputStream bis = new BufferedInputStream (new FileInputStream("equiptbl.sgm"));
int data;
while((data = bis.read()) != -1)
sos.write(data);
bis.close();
sos.flush();
sos.close();
%>
<jsp:forward page= "HU5A_Equipment_Browse.jsp" />
</jsp:useBean>
============================================
The code for the other pages is the same with the exception of the filename xxx.sgm and the bean id.
I very much appreciate your help. Thanks!

Hello Paulo,
thank you for your answer, but i'm using type 04 XML for SEPA.
when i select Type XML, the fields "output to file system" and "filename" are hidden.
i dont understand why ...
