download a file from jsp

Thread view: 
prado - 15 Jun 2006 11:55 GMT
Hi,

 I have a jsp where I show a table. I am trying to download this jsp
like excel file. To do this I put this code in my jsp:
<%
    response.setBufferSize(65536);

    response.setHeader("Content-type","application/vnd.ms-excel");

     String nombre = "fichero_excel.xls";

     response.setHeader("Content-Disposition","attachment;
filename=\"" + nombre + "\"");

    response.setHeader("Pragma","no-cache");
%>

It works fine if I use only one browser.

The problem is when I try to do this but from 2 browsers at the same
time. From each browser I can download a part of the file but not the
complete file.
It seems the browsers are sharing the bandwidth and when it starts to
download a file the other stops.

Can you help me please?

Thanks.

this code is not complete. How do you write into the jsp?
I appreciate the shortness, but try to post a complete example
Also, if the only purpose of the jsp is to download a file, you should
use a servlet

they are not sharing bandwidth, they are sharing your jsp, or better,
the servlet generated from your jsp. Try to put some log messages in
your jsp at the begin and the end, to see how it goes

you are downlading an html as xls? And that works? Wow
This looks a bit confusing. If you use a jsp with html then don't set
the content-type. If you need an excel file I don't see how you can
write html in it. Again, you should use a servlet
Are you by chance trying to open an HTML file with Excel?

are you sure the values you get in this attribute are correct? How about
logging them?

Hi,

  Yes I am downloading the html as xls and it works.

 You ask me if this attribute are corect, the answer is yes, i have to
checked with the database and the attribute is correct. is not correct
for you?

String[][] astrRdoAnalisis = (String[][])
request.getAttribute("astrRdoAnalisis");

interesting

> for you?

what I meant is: are you sure that the value of the attribute is correct
when the page is loaded? In othe words: maybe the page is working
correctly, it simply gets the wrong values.
For the rest it look basically okay, except the strange html/xls mix. I
just wouldn't mix html and java code like that, but that's a minor problem.
Even if you have more threads accessing the page that shouldn't bother you.
prado - 15 Jun 2006 16:31 GMT
I send the array from a servlet to the jsp.

I am going to make a file and download from a servlet. I believe you
have reason. It is better.

 have you an example of a servlet that it makes the download?

Thanks.
Andrea Desole - 15 Jun 2006 17:14 GMT
> I send the array from a servlet to the jsp.

Right. But how do you make it? Is it possible that, when I download the
second time, the application modifies the same attribute that is used to
download the first time?

>  I am going to make a file and download from a servlet. I believe you

You want to write the html to a file?
To download a file a servlet is usually the solution (unless of course
you have a static file somewhere on the server). In this case, however,
you have a special situation where you want to open with Excel a file
with html content. Quite unusual. In this situation your solution,
although a bit weird, might be not so bad.
Also, I'm afraid that a servlet won't solve your problem.
Besides, if you really want to do it there is no point in writing
everything to a file first.

What I would suggest is to try with only that jsp, no servlet before it
and no fancy request attributes. Just take the content for your table
from a static file, or make it directly in the JSP. And then see what
happens

By the way: what application server are you using?

>   have you an example of a servlet that it makes the download?

It's not very different from what you put in the JSP: set the content
type, add the disposition header, and write to the writer.
Loads of examples on the internet. Just google it. For example

I have a sneaking suspicion that I know what's wrong here. Is it
possible that the array you're sending from the servlet is an instance
variable? If so, you need to be aware that multiple requests to the
servlet will all share the same array. You need to make it a
method-local variable, and pass it as an argument if you need to access
it in more than one method of the servlet, or possibly to instantiate a
new array for each request and place it in the session to share it.

Just a quick note to Andrea: The HTML/XLS thing is actually quite
useful. Google 'excel "web connectivity kit"' if you want to know more
about this.

this is an option. But it's also possible that, without using instance
variables in the servlet, this attribute is made in a way (via
session/static variables, for example) such that different calls to the
servlet actually put the same object (intended as reference) in the
request. We cannot know if we don't know how this attribute is built.

has been a while since I made my last MS application :-)
I can imagine that someone wants to open a page directly with Excel. I
actually have never thought of it. This must be the reason why I think
that changing the content type of an HTML page looks a bit strange.

Too true, but my money is on the instance variable. It's one of those
mistakes that's just too easy to make, forgetting that you don't get an
instance per request.

Yeah, yeah. Showoff. ;^)

If you think that's strange, you should see the CSS extensions for
handling dates and numbers. <g>

CSS? As in Cascading Style Sheets? I think I'll trust you :-)

Does that compile? I can't see where you've declared your variable
"conn". If you're sharing a single connection between requests, that
could well be your problem.

Luke

Hi,

Yes, the servlet calls to jsp. The servlet read the database and it
stores the information in astrRdoAnalisis variable and then send this
variable to the jsp. is correct?

the connection declaration is before the try.

solve it.
I have to trace the file and apparently it send the paremeter well but
the files are incorrects. The files are incomplets.

It does look a bit strange. I can't see anything bad in the code.
I have one more question. I can see there is another request attribute,
analysis, that you read in your servlet. Do you have another servlet
that is called?

What do you mean? The results from the database are incorrect?

the steps is the next:

(analyz.jsp)

I have look the logs and the file has downloaded to the computer and
while the the jsp is working. I don't undestand why the file has
finished to download and while the jsp is still executing.

okay. So I think you posted the servlet and the second jsp. Can you post
the first jsp, so the picture is complete?

Date fecha = new Date();

java.sql.Date fechaSQL = new java.sql.Date(fecha.getTime());

Calendar calendario = Calendar.getInstance();
calendario.setTime(fecha); // fecha es el Date de antes.
String strHour = String.valueOf( calendario.get(Calendar.HOUR) );
String strMinute = String.valueOf( calendario.get(Calendar.MINUTE) );
String strSecond = String.valueOf( calendario.get(Calendar.SECOND) );

String nombre =  "FILE" + strHour + strMinute + strSecond + ".xls";

System.out.println(  " IN OF  " + nombre );

    response.setContentType( "application/x-download" );
