How to fetch dynamically generated text file

Caveat: I'm actually using CSP, not JSP, but the scripting methods are very similar. A JSP answer will probably apply to CSP as well.
Currently, I have a dynamic content page that which I fetch on a submit action using response->getRedirectURL("xxx") where xxx is the URL of the dynamic page. The page displays fine in the browser, but what I would like to have it do is cause a file save dialog to appear so that the user can save the page as a text file.

Set the MIME/ content type to "text/plain"
You then need to tell the browser to not try and render the contents but to treat it as an attachment.
Set the header "Content-Disposition" with the value "attachment; filename="yourFilenameHere".
And you do realize, posting about CSP here might get you flamed :)

How to save dynamically generated PDF files with proper file name?

Hi,
I need to save the pdf file with default name which generated by
dinamically.
this is the code i am trying to save by default
protected void processRequest (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
OutputStream bos = response.getOutputStream ();
// this returns pdf byte array
byte ios[] = callReport ( reportId_param , fullyQualifiedReportClassName , paramHashMap ) ;
response.setContentType ("application/pdf");
// reportId_param and reportName_param supplied from some where
String docName = reportId_param + "_" + reportName_param ;
if( fromDate_req != null && toDate_req != null )
                String dateStr = fromDate_req + "_to_" + toDate_req ;
                dateStr = dateStr.replaceAll ( "/" , "_" ) ;
                docName = docName + "_" + dateStr ;
// here docName would be like "RP_COM_COLL_01_Message_Details_03_09_2008_to_03_09_2008"
response.setHeader ("Content-Disposition","inline; filename=" + docName ) ;
bos.write (ios);
bos.flush ();
}the above code produces pdf in browser when calling this URL
http://localhost:8080/DAD01TN0801027/RWReportServlet
In browser we can save this PDF by using two ways
1. File -> Save As
2. By using Save Icon within the PDF toolBar
both the actions uses the file name "RWReportServlet" as default instead of using docName
Can any one help me please
Regards
Sakthivel.

That said, your code is not very efficient. You're storing the complete PDF file in memory. What if the PDF file is fairly large? And what if multiple users download multiple large PDF files simultaneously? Your server would run out of memory. Rather use InputStream instead of a raw byte[]. And preferably buffer it.
You should also be setting the content-length header by the way.

Problem in dynamically generating the file upload field

Hello all
I am using netbeans 5.5 and visualwebpack for my jsf project.
i have a problem in dynamically generating the file upload field and using it.
I have a panel say "panelA" which holds file upload fields.
Depending upon the count value i generate the file upload field using following code snippet:
Upload upload1 = new Upload();
upload1.setId("upload1");
getPanelA.getChildren().add(upload1);
The page successfully shows up the file upload fields. While the user clicks the submit button, i have used following logic to perform upload:
List components = getPanelA().getChildren();
for(int i = 0; i<components.size(); i++){
if(components.get(i) instanceof Upload){
UploadedFile uploadedFile = ((Upload)components.get(i)).getUploadedFile();
I am getting this UploadedFile object null.
How can i solve this problem.

Anyway,
I solved the problem.
Actually i was using label property of the upload field due to which i got null pointer exception.
I removed the label property of the upload field and things worked as i wanted.

Generating Text files from PL/SQL

To generate Text files from PL/SQL on SERVER, i can use UTL_FILE
package, but how do i create text files on client ( i.e., on the
C: drive ) by executing anonymous PL/SQL blocks.
Thanks in advance.

You can use DBMS_OUTPUT to display stuff to the screen and the
SQL*Plus SPOOL command to write screen output to a file on your
local drive.

Generating Text file from table using Shell script

MALLIK_ACCT ...17-SEP-11 .... 909570766
I put dots(.) for illustration purpose.
column data length may icrease some times . it shoudl automatically adjust column and data so that they are in alignment. thanks in advance.

How to read a whole text file into a pl/sql variable?

I want to read the whole text file in one shot, not just one line at a time. Shoud I use Utl_File.Get_Raw or is there another more appropriate way to do this?

How to scan/ read a text file, pick up only lines you wanted.

I'm new to Labview, I trying to wire a VI which can read a text file
example below:
Example: My Text File:
1 abcd
2 efgh
8 aaaa
1 uuuu
and pick out only any line which start with number 1 (i.e 1 abcd)
then output these 2 lines out to a a new text file?
Thanks,
Palmtree

Hi,
How do you creat your text files? Depending on the programm, there is added characters in the beginning and at the and of the file. So here you will find a VI to creat "raw" text files.
To debug your VIs, use the probs and breakpoints, so you can solve the problem by your self or give an more accurate description of it.
There is also the VI that read a integer and two strings (%d %s %s)

How do I open a text file to sort using bubble sort?

Hi,
I have a text file, which is a list of #'s.. ex)
0.001121
0.313313
0.001334
how do you open a text file and read a list? I have the bubble sort code which sorts.. thanks

I wrote this, but am getting a couple errors:
import java.util.*;
import java.io.*;
public class sort
     public static void main(String[] args)
          String fileName = "numsRandom1024.txt";
          Scanner fromFile = null;
          int index = 0;
          double[] a = new double[1024];Don't use double. You should use something that implements Comparable, like java.lang.Double.
          try
               fromFile = new Scanner(new File(fileName));
          catch (FileNotFoundException e)
System.out.println("Error opening the file " +
" + fileName);
               System.exit(0);
          while (fromFile.hasNextLine())
               String line = fromFile.nextLine();
               a[index] = Double.parseDouble(line);Don't parse to a double, create a java.lang.Double instead.
               System.out.println(a[index]);
               index++;
          fromFile.close();
          bubbleSort( a, 0, a.length-1 );No. Don't use a.length-1: from index to a.length-1 all values will be null (if you use Double's). Call it like this:bubbleSort(a, 0, index);
public static <T extends Comparable<? super T>> void
d bubbleSort( T[] a, int first, int last )
          for(int counter = 0 ; counter < 1024 ; counter++)
for(int counter2 = 1 ; counter2 < (1024-counter) ;
) ; counter2++)Don't let those counter loop to 1024. The max should be last .
                    if(a[counter2-1] > a[counter2])No. Use the compareTo(...) method:if(a[counter2-1].compareTo(a[counter2]) > 0) {
                         double temp = a[counter2];No, your array contains Comparable's of type T, use that type then:T temp = a[counter2];
// ...Good luck.
