How to download file with Save As dialog

I am trying to download files with a Save As dialog, according to Jason Hunter's instructions in Jave Enterprise Best Practices.
String filename = "content.txt";
// set the headers
res.setContentType( "application/x-download" );
res.setHeader( "Content-Disposition", "attachment; filename=" + filename);
// send the file
OutputStream out = res.getOutputStream();
returnFile( filename, out);
The file content.txt is in the root directory of my webapp. But I get this stack:
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
java.io.FileNotFoundException: content.txt (The system cannot find the file specified)

The root of the webservers changes from server to server and
sometimes it depends on the path you run webserver exe.
The best i have found to overcome this kind of problems is by
using getResourceAstream() method which basically looks at classpath locations only, but still this has some problems like it should kept at the
specified classpath becoz the getResourceAsStrem() method is not static
method and it always associated with the class object and the file
accessing also should be in the same package/classpath.
by using getResourceastream you cannot look at other places (except classpaths)
and this should be used only if you looking for .properites definitions.
the Second best method is
see you have a file called "context.txt" right
before you create a file, first create a directory at the root, let say
"\tmp"
and then create a file \tmp\context.txt
and then open an output stream to it either using fileoutputstreamm...
and then write all output content to servlet/client output stream.
this will be the best becoz you are specifying the "\" the root
and this is common for all operating systems and definitely it will create at the root directory either serverroot or harddiskdrives root
so you will never missout and the exceptin will also not comes along the way
cheers..
if you get new thing , let me know

Thank you very much by any help.

Sql loader how import a file with save the actual row number in a db field

Hey,
how can i save the row number for each row in a file into a database field i the same table with the sql loader (sqlldr)?
test data:
john doe
joe meier
table:
name surname line_number_in_file
john doe 1
joe meier 2
and so on ... an if an line is discarded because it is empty for example it should be as this:

but if one of the when clause faild or some rows are
rejectet the sequence is not right.Did you read the link?
"If a record is rejected (that is, it has a format error or causes an Oracle error), the generated sequence numbers are not reshuffled to mask this. If four rows are assigned sequence numbers 10, 12, 14, and 16 in a particular column, and the row with 12 is rejected, the three rows inserted are numbered 10, 14, and 16, not 10, 12, and 14. This allows the sequence of inserts to be preserved despite data errors. When you correct the rejected data and reinsert it, you can manually set the columns to agree with the sequence."
also if you read multiple lines and they inserted in
the wrong order the number from the sequence is not
the line number...what do you mean with "reading multiple lines and wrong order?"

How do I call browser Save As dialog box before downloading pdf files?

How do I call browser Save As dialog box before downloading pdf files?
Here's my favorite scenario:
1. User clicks button
2. Save As dialog displays
3. User chooses location
4. A set of PDF files download to that location OR a single zip file downloads
Background:
I want to ensure the user sees that files are being downloaded. I'm delivering content to users who may not be Web savvy.
Concern:
1. User has no clue how to find downloaded files or that files have even downloaded.
2. I'd like to deliver the set as zip files. Not sure if self-opening zip files still exist.
FYI:
I'm using jQuery UI buttons. Not sure if that factors into response.

Just for clarity, I'm not forcing a download. The user will click a button.
Click a button or click a link, either way you're technically executing a script to force a download.
I'm assuming that's the php file resident on the server.
Yes but that's only part of it. Once the contact form executes, another script is called up which opens the browser's download dialogue.
Is there a php script for simply calling the Open/Save dialog box?
Yes.
<?php
/* This short script forces a file download.
   For simplicity, it's intended to be used for a single file.
   You can use multiple copies of this file (with unique names)
   with different variable values to use it with multiple files.
   Use of this script has a side-effect of hiding the location of the
   file on your server.
// full server path to file to be downloaded (including filename)
$Path2File = "path/to-file-on-server.zip";
// the filename
$theFileName = "name-of-file.zip";
//the work gets done here
header ("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header ("Content-Type: application/octet-stream");
header ("Content-Length: " . filesize($Path2File));
header ("Content-Disposition: attachment; filename=$theFileName");
readfile($Path2File);
?>
Name this file zip2download.php.
Add a link to your HTML page:
<a href="zip2download.php">Download Zip</a>

How can I upload and download files with uiXML?

I want to implement upload and download files with uiXML. In some previouse topic I got answare to look in AbstractPageBroker class in JavaDOC. I did it but this is a very-very little resolution description for this problem. I think for developers YOU (UIX Team) must in very quick time to put some examples on the NET because this is a nice technology but with adecvate samplase and developers guide it will be dead very soon. I digging this forum for information. I see many many people have same problems about this technology. They like it and want to use and try but documentation is very very poor.
WE WANT EXAMPLES and separate forum for UIX. I think it deserve this.
If You have any more detailed documentation would be nice to put on the net. I have uixdemo.zip file but this is in very early fase of development. I downloaded it before fwe months. And now I can't find it anymore on youre site. What happend?

Attila -
I went back and re-read the JavaDoc for AbstractPageBroker and MultipartFormItem and put together the following sample PageBroker based on the description from the JavaDoc:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import oracle.cabo.servlet.BajaContext;
import oracle.cabo.servlet.Page;
import oracle.cabo.share.util.MultipartFormItem;
import oracle.cabo.servlet.xml.UIXPageBroker;
* An extension of UIXPageBroker which stores all uploaded
* files in the temporary directory.
public class UploadingPageBroker extends UIXPageBroker
* Override of AbstractPageBroker.doUploadFile() which saves
* all files to the temporary directory.
protected String doUploadFile(
BajaContext context,
Page page,
MultipartFormItem item) throws IOException
// Get the location of the file to create in the temp directory.
// Of course a real application probably wouldn't upload files to
// the temp directory - just using this contrived example to
// demonstrate basic uploading support.
File file = _getFile(context, item);
if (file != null)
// Create a FileOutputStream. Of course, a real application would
// probably want to buffer the output
FileOutputStream out = new FileOutputStream(file);
// Write out the file
item.writeFile(out);
// Close up the output stream
out.close();
// We can return a value here to add to the PageEvent
// if so desired.
return null;
// Gets the File for the item that we are uploading
private File _getFile(
BajaContext context,
MultipartFormItem item
// Get the file name
String name = item.getFilename();
// If we don't have a file, bail...
if (name == null)
return null;
// Get the path to the temporary directory
File dir = _getTempDir();
// Return the File object
return new File(dir, name);
// Returns the path to the temprary directory
private File _getTempDir()
// Get the temporary directory from the ServletContext
ServletConfig sConfig = getServlet().getServletConfig();
ServletContext sContext = sConfig.getServletContext();
return (File)sContext.getAttribute("javax.servlet.context.tempdir");
In this sample, each uploaded file is simply saved in the temporary directory. You'll want to replace the code that creates the FileOutputStream for the uploaded file to use whatever OutputStream makes sense for your application.
BTW - I used the following UIX page to test this out:
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://xmlns.oracle.com/uix/controller">
<content>
<pageLayout xmlns="http://xmlns.oracle.com/uix/ui">
<contents>
<form name="uploadForm" usesUpload="true">
<contents>
<fileUpload name="uploadedFile"/>
<submitButton name="upload" text="Upload"/>
</contents>
</form>
</contents>
</pageLayout>
</content>
</page>
Hope this sample helps with the uploading part of your question. I'll see if I can provide a download sample in a later post.

How do I move the 'save as' dialog out of my way in Preview?

I have a stack of pdf files to rename, for which I need to read the contents. The filenames are composed from the authors, title and date which are inside the documents. The trouble is that I can't save them without the 'save as' dialog occluding the document, which I need to see in order to fish out the authors, title and date.
How can I move the 'save as' dialog off the document view?
Is there another way around this problem?
I'm using Snow Leopard's version of Preview, in case it matters.

Yes, that makes it pretty much impossible if you need to grab text from various places first and assemble it into the file name you want.
I can copy/paste text out of a PDF with the Adobe Reader into a Save As dialogue box, but then run into your same issue with Preview. I can't move back to the document to get another snippet of text.

If you look around the forum for a bit, you will see that there is no notion of file systems on JavaCards (lexdabear posted this information less than two hours ago :-)). To store files, you will have to write an applet to hold byte arrays of the required size and handle receiving and sending of these.
As for documentation, you should have a look at the GP (General Platform) specification at http://www.globalplatform.org/, which defines communication between smart cards and other devices, as well as Sun's own JavaCard pages (http://java.sun.com/products/javacard/), which contain several useful resources on JavaCards.

Just drag the file from the Download folder to the folder of your choice in Finder. If you are using Safari you can designate a new default download destination in Safari>Preferences>General tab, 'Save Downloads to...'. Other browsers should have a similar option in their preferences.

Sum Encrypt does not recognize a copy of a file through linux. How decrypt this file with Sum Encrypt?

Sum Encrypt does not recognize a copy of a file through linux to Mac 0S9. How decrypt this file with Sum Encrypt?

Hello, and welcome to Apple Support Communities!
I am not familiar with the program that you list, however files in OS 9 use things called Resource Forks (rather than file extensions) for filetype and creator.
If you sent a file through Linux these resource forks probably got stripped and now the file is nothing to your Macintosh.
It is best to BinHex your files (.hqx) before leaving the HFS file system so that their resource forks are preserved.

How Merge Temp File With Photoshop File

Hi Friends,
I Deleted Temp File, And Now get A Error when open photoshop file " Could Not Complet ... is not a valid photoshop format " and my file size is 60mb
and i have temp file that size is 2.50GB but How Merge Temp File With Photoshop File?
Thank you So Much

You can search for recovery programs but most likely if it a temp file is not an image file. You could also try renaming the file to have an image file type and try to open with Photoshop. Again its most likely not an image file. Photoshop only supports some image files formats.
