IE hangs trying to open Excel

hello -
The resultset only has 6-700 rows that is displayed on the JSP, still, IE 
just hangs when it's trying to open up Excel (there is plenty of memory 
available). Anybody has any idea why...? Thanks a lot in advance.

It is likely that you need to do something like this:

             response.setContentType("application/vnd.ms-excel" );
             response.setHeader("Content-disposition",  
"inline;filename="+filename);

before streaming out your file.

Also make sure your JSP has not output whitespace in front of your  
Excel.

This is easy to do.

Here is the proper way.

<%@ page language="java" session="false" import="java.lang.*"  %><%
             response.setContentType("application/vnd.ms-excel" );
             response.setHeader("Content-disposition",  
"inline;filename="+filename);
// your code
  %>

And here is the accidental whitespace way:

<%@ page language="java" session="false" import="java.lang.*"  %>
  <%
             response.setContentType("application/vnd.ms-excel" );
             response.setHeader("Content-disposition",  
"inline;filename="+filename);
// your code
  %>

If either of these clues fail you then you'll need get help from  
someone who knows OC4J and/or struts. We use Tomcat and rolled our own  
framework.

HTH,
Dave

Re: IE hangs trying to open Excel

The problem is that the dialog box that would ask you if you wanted to 
open it or save it, never appears. so you can't save it either.
Unless in the code I'd force the file to be saved - I will actually test 
that, thanks. Then it narrows down the problem a bit.

Are there any problems opening the file if you have
the web app save the file, and then open it manually
using Excel or IE?

We're using OC4J, unfortunately (not the best behaving container). And 
yes, we're using POI to generate the workbook; also using Struts for 
framework, so a custom action is doing all that. So what is to blame...?

thank you!

Re: IE hangs trying to open Excel






Hi -

This sounds more like a web server issue. What is your servlet 
container? Are you using POI to create the workbook from within a JSP? 
If so that can be trouble because Excel is a binary format and JSP is 
text.

In our experience we served up Excel OK with a JSP until we upgraded 
our Tomcat from 4.1.29 to 4.1.31. At that point the catalina connector 
for Tomcat got more strict and we had to take a servlet approach. I 
can share some servlet code if this is correct.

Regards,
Dave

Is that just happening on some files and not others.  I've had problems
with an Altiris Agent that cause Excel to open very slowly but not hang.
