FileReference.upload in JSP problem

Help !!!
We've succesfully implemented file upload via flash in jsp
tomcat (using FileReference.upload() in actionscript 2.0 ), but for
some reason, parameters posted in the url to the file upload
handling script (ej. "uploadScript.jsp?id=1") are lost, ie: the
id=1 is lost.
To double check flash correctly sending params , we've
implemented the same flash object in php and parameters are posted
fine.
Any Ideas, I'm desperate.
thanks.

Therefore, can anyone tell me what have happened?The problem is in the scope. Request objects are local to jspService() method (Sorry, i forgot the name). So it's life is not long enough to be found in other pages. For your case, session is the perfect scope.
session.setAttribute() is the smartest. u can use pageContext.setAttribute method also. I do not have any idea about other solutions.

FileReference.upload() not working in Firefox

Hi,
i have a strange problem - my Flex application uses the FileReference.upload() to upload images to the server. ServerSideScript ist pure PHP.
It is working in IE but not in FF
Any help is really appreciated since i'm running out of ideas...
<?php
$target_path = "../xml/akten/dokumente/";
$target_path = $target_path . basename( $_FILES['file']['name']);
if(move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {
    echo "The file ". basename( $_FILES['file']['name']).
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
?>

I am facing the same problem.
Has anyone any solution on this.
Thanks

Antivirus software breaks FileReference.upload() method...

Hi there,
I'm a Flash developer who's run into an interesting problem since upgrading to AVG 9 (free antivirus software).
I use Flash to facilitate large uploads to websites (eg. video). I've built plently of upload widgets that use Flash's FileReference.upload() method to send a file from a users computer to a webserver.
It seems that since upgrading to AVG 9, the bytesLoaded property of a ProgressEvent is being updated at warp speed - a 30mb file appears sent to a server in less than a second! Which is ridiculous. So in an instant, the bytesLoaded property equals the bytesTotal property. Seemingly an arbitrarily time later, the Event.COMPLETE event fires (I think this arbitrarial illusion is caused by the upload continuing in the background). If everything was running as it's supposed to, this should generally be followed by a DataEvent.UPLOAD_COMPLETE_DATA event firing. But now, because of all this weirdness, no DataEvent.UPLOAD_COMPLETE_DATA event is firing.
After a bit of websurfing I found other developers having problems with this because of virus software - so I've uninstalled AVG and "voila!", Flash now works as it is supposed to when uploading a file again.
I guess I could build a polling timer into my uploader to continually ping the server to check that my upload had complete and grab my upload complete data that way, but that'd be annoying as heck.
Any ideas what's going on? This is kind of a massive problem, ProgressEvent returning bogus bytesLoaded data, isn't it?
Kind regards,
James.

I agree in disabling the LinkScanner. Open AVG User Interface, Dbl click on the LinkScanner and Untick the "Enable AVG Search-Shield" and the "Enable Active Surf-Shield" then SAVE the changes made.

Filereference.upload ... works on localserver but not on webserver

hello;
I'm uploading images via filereference.upload ... works fine when testing on local machine with apache. once I port everything to my web-based server ( shared server with a webhosting company ), the upload fails.
- do not get any errors such as SECURITY_ERROR , HTTP_STATUS , IO_ERROR
- do get 1 PROGRESS event - only 1 - but it already shows 100%
- do get COMPLETE event after a couple of seconds
- do not get UPLOAD_COMPLETE_DATA, but do get it on localhost
- do not get the image on the remote server
- my local php is 5.2 ... webserver php is 4.4 ...
- I have tried setting 757 as file permissions for image directory
- all php, swf, image directories are in the same domain, though in different directories.
- I have tried uploading the image to the same directory as php directory itself
any thoughts?
thanks,
dsdsdsdsd

not exactly what was not working, but my webhost updated my php module to php 5.2, and my uploader works.

Flex 3 - CF9 filereference.upload test

Hi
i run a filereference.upload test flex application which uploads a file through a coldfusion server.
i’m using flex 3 and coldfusion 9.
i’m also passing parameters in the URLRequest that points to the upload cfm file.
when i run my test using the built-in web server (Jrun) all seems to work just fine
when i run the same test on a coldfusion instance that runs on Apache web server, it throws a I/O Error…
i suspect i’m missing some kind of a configuration i need to perform when moving to a production setup rather then a development environment…
can anyone guide me through this?
does it have to do with security? on the client? on the server?
i’m still running on localhost…
summery...
attached are the mxml file and the cfm file
works great on built-in server
throws a I/O error when runs through Apache
cheers

If you want to test against another implementation, I wrote a Flex Upload component and CFML script a while back. I've used it regularly on IIS and Apache server (and my localhost) without having to modify the configuration at all. Speaking of the config, Daverns could be totally right ... and this post is not to refute or argue the point about Mod_Security; rather, its only meant as another options to test, since you were having trouble with it on the production server.
The attached Zip archive contains three files: FileUpload.mxml, SampleUsage.mxml, and fileUpload.cfm. The files are heavily commented but feel free to ping me if you have any issues with it.
Good luck!

FileReference.upload response is truncated on Mac

I have flash as3 code that will upload a file to my server using FileReference.upload but when receiving the DataEvent.UPLOAD_COMPLETE_DATA event * on MAC only *, I find that event.data will get truncated after a certain number of bytes/characters (looks to be about 2400 Bytes). I know that my server is returning more data than this because I can see the raw response using an HTTP sniffer program. Is there a reason my response data is getting truncated on macs and is there anything I can do to avoid this truncation?
My server side code is running on ASP.NET and IIS if that is relevant. The Content-Length HTTP Header value also appears to be set correctly. This looks to work on windows (firefox 3.6, chrome, and IE) but fails consistently on mac (firefox, chrome, safari).
Any ideas?

Upload file form problem in JSP portlet !!!

Hi!
I use "OrdHttpUploadFile" class for upload file in JSP portlet to database!
Problem is that this class must use FORM ENCTYPE="multipart/form-data" whis I suppose dont work in portlet!?
Which FORM ENCTYPE should I use in portlet! Or there is some other solution for upload file in JSP portlet!?
Thanks!
Kristjan

Thanks for u r reply Mr.Prasad.
Sorry for the delay for reply.
My scenario is in 2 phases
Phase 1. I am taking input from the front end using jsp and writing the contents in to a file and then downloading that file on to my desktop.(Now let us say this one as file downloading)
Phase 2. Now I had designed a page,which locates the downloaded file by using the following tag.
<td><input type ="file" name ="xmlFileName"></td>
In the downloaded xml file I am having applicationid. I am checking whether the application id already xists in the database (or)not.
If already exists in the database , the end user will get one confirmation msg,saying application already exists in the database.
If the user clicks ok again the request has to go to the servlet.
Now the actual problems are
1. When I locate the file on the desktop let us say c:\desktop\krish and click on submit button, it is locating to the file that is present in the server(this is the case for the first time means before checking the application id in the database).
2. when the end user clicks "ok" on the confirmation box , I am not getting the file name,that has to be submitted to the servlet.
Can u plz help me how to resolve this issue.
regards,
Krish

FileReference upload failure

Hi, I got a FileRefrence instance for a simple upload and it did work for some time in the past, but now I just can't discover what made it stop woking. Can anyone help me find it out? To simplify, I took only the necessary code (not working as the full version). Here are some details:
1. I'm using Flash Player 9 (this can't change because it is a part of a bigger project). My current host machine is a Windows Vista one. The sandbox is set to network access.
2. The FileReference calls a simple php script hosted at an Apache server (Linux). The script permissions are set to 644 (it works for file uploads coming from plain html pages) and I set the folder permission to 777 just to avoid any other source of errors. Here is the simple code for the php script:
<?php
// receiving variables
$uid = trim($_POST['uid']); // just to check for a post variable that I must send while uploading (won't work even if I revome it)
// a file to check if the script is really called
$myfile = fopen("upload.txt", "wb");
fputs($myfile, "file upload for uid $uid\n");
// receiving the file and saving it
if ($_FILES['Filedata']['name'] != "") {
    $newName = preg_replace('/[^a-z0-9_\-\.]/i', "_", $_FILES['Filedata']['name']);
    $newName = preg_replace('[ \f\r\t\n]', "_", $newName);
    @move_uploaded_file($_FILES['Filedata']['tmp_name'], $newName);
    fputs($myfile, ("new received filename: " . $newName . "\n"));
} else {
    fputs($myfile, ("no file received\n"));
fclose($myfile);
?>
This script writes a file named "upload.txt" so I know it was really called. If I run it directly from the browser, everything is ok.
3. My AS3 code just starts the browsing for a file (I'm using a 500k mp3 to test). By following the program trace I see that the upload actually happens, but when it finishes, I get an IO error (I'm using the very same url address for the script that I use at the browser). When I check the server, I see that no "upload.txt" file is written, so the script was really not found. Here is some of the AS3 code I'm using:
private var urlSend:URLRequest = new URLRequest("my address to the php script (http)");
private var urlData:URLVariables = new URLVariables();
private var fileTansfer:FileReference = new FileReference();
private function uploadFile():void { // call by a button click
     this.urlData.uid = "1";
     this.urlSend.method = URLRequestMethod.POST;
     this.urlSend.data = this.urlData;
     this.configureListeners(this.fileTansfer); // all listeners are correctly set
     this.fileTansfer.browse(new Array(new FileFilter("Audio files", "*.mp3")));
// listeners set here
private function selectHandler(event:Event):void {
     var file:FileReference = FileReference(event.target);
     trace("selectHandler: name=" + file.name + " URL=" + this.urlSend.url); // prints correclty
     file.upload(this.urlSend);
As I said before, I get traces from progress handler and when it reaches the end, I get the IO error message:
ioErrorHandler: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2038: Erro do arquivo de E/S. URL: (my correct url here)"]
Just for checking I add a Loader instance and used its "load" method with the same "urlSend" variable. It worked and the php script generated the output file...
Does anyone know what's happening? Could it be some permission problem? Why can't the FileReference find my script assuming its url is ok?
Thank you in advance!

How did you resolve the above error ? Thanks.

File upload with jsp

I am trying to upload a file to a mysql database (using a jsp tomcat 4.1 container) for each new member of my website (typically a cv which is a .rtf word file). I have used the example on the oreilly page and have managed to get the image of the file I have uploaded. Now I am trying to save this into my database for each member so that they can enter all of their details on the one page i.e. name age etc and also a browse for file button which will store the path of their file on their computer. When they click the submit button, all of their details are then stored into the database by the resultant page which outputs wehter they have been successful or not.
The upload bean code (from the oreilly site):
package com.idhcitip;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.ServletInputStream;
import java.util.Dictionary;
import java.util.Hashtable;

this.savePath = savePath;

return null;
return (String) fields.get(fieldName);
private void setFilename(String s) {
if (s==null)
return;
int pos = s.indexOf("filename=\"");
if (pos != -1) {
filepath = s.substring(pos+10, s.length()-1);
// Windows browsers include the full path on the client
// But Linux/Unix and Mac browsers only send the filename
// test if this is from a Windows browser
pos = filepath.lastIndexOf("\\");
if (pos != -1)
filename = filepath.substring(pos + 1);
else
filename = filepath;
private void setContentType(String s) {
if (s==null)
return;
int pos = s.indexOf(": ");
if (pos != -1)
contentType = s.substring(pos+2, s.length());
public void doUpload(HttpServletRequest request) throws IOException {
ServletInputStream in = request.getInputStream();
byte[] line = new byte[128];
int i = in.readLine(line, 0, 128);
if (i < 3)
return;
int boundaryLength = i - 2;
String boundary = new String(line, 0, boundaryLength); //-2 discards the newline character
fields = new Hashtable();
while (i != -1) {
String newLine = new String(line, 0, i);
if (newLine.startsWith("Content-Disposition: form-data; name=\"")) {
if (newLine.indexOf("filename=\"") != -1) {
setFilename(new String(line, 0, i-2));
if (filename==null)
return;
//this is the file content
i = in.readLine(line, 0, 128);
setContentType(new String(line, 0, i-2));
i = in.readLine(line, 0, 128);
// blank line
i = in.readLine(line, 0, 128);
newLine = new String(line, 0, i);
PrintWriter pw = new PrintWriter(new BufferedWriter(new
FileWriter((savePath==null? "" : savePath) + filename)));
while (i != -1 && !newLine.startsWith(boundary)) {
// the problem is the last line of the file content
// contains the new line character.
// So, we need to check if the current line is
// the last line.
i = in.readLine(line, 0, 128);
if ((i==boundaryLength+2 || i==boundaryLength+4) // + 4 is eof
&& (new String(line, 0, i).startsWith(boundary)))
pw.print(newLine.substring(0, newLine.length()-2));
else
pw.print(newLine);
newLine = new String(line, 0, i);
pw.close();
else {
//this is a field
// get the field name
int pos = newLine.indexOf("name=\"");
String fieldName = newLine.substring(pos+6, newLine.length()-3);
//System.out.println("fieldName:" + fieldName);
// blank line
i = in.readLine(line, 0, 128);
i = in.readLine(line, 0, 128);
newLine = new String(line, 0, i);
StringBuffer fieldValue = new StringBuffer(128);
while (i != -1 && !newLine.startsWith(boundary)) {
// The last line of the field
// contains the new line character.
// So, we need to check if the current line is
// the last line.
i = in.readLine(line, 0, 128);
if ((i==boundaryLength+2 || i==boundaryLength+4) // + 4 is eof
&& (new String(line, 0, i).startsWith(boundary)))
fieldValue.append(newLine.substring(0, newLine.length()-2));
else
fieldValue.append(newLine);
newLine = new String(line, 0, i);
//System.out.println("fieldValue:" + fieldValue.toString());
fields.put(fieldName, fieldValue.toString());
i = in.readLine(line, 0, 128);
} // end while
This works fine and I can access the image name of the file by using the commands in my jsp code(on the resultant page of the new member form):
<%@ page import="java.sql.*, com.idhcitip.*"%>
<jsp:useBean id="TheBean" scope="page" class="com.idhcitip.FileUploadBean" />
<%
TheBean.doUpload(request);
out.println("Filename:" + TheBean.getFilename());
So I am wondering how can I then store this image into a text blob in the database?
I found some code on the java.sun forum, but am not entirely sure how I am meant to use it?
package com.idhcitip;
import java.sql.*;
import java.io.*;
class BlobTest {
public static void main(String args[]) {
try {
//File to be created. Original file is duke.gif.
//DriverManager.registerDriver( new org.gjt.mm.mysql.Driver());
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String host="localhost";
String user="root";
String pass="";
String db="idhcitip";
String conn;
// create connection string
conn = "jdbc:mysql://" + host + "/" + db + "?user=" + user + "&password=" +
pass;
// pass database parameters to JDBC driver
Connection Conn = DriverManager.getConnection(conn);
// query statement
Statement SQLStatement = Conn.createStatement();
/*PreparedStatement pstmt = conn.prepareStatement("INSERT INTO BlobTest VALUES( ?, ? )" );
pstmt.setString( 1, "photo1");
File imageFile = new File("duke.gif");
InputStream is = new FileInputStream(imageFile);
pstmt.setBinaryStream( 2, is, (int)(imageFile.length()));
pstmt.executeUpdate();
PreparedStatement pstmt = Conn.prepareStatement("SELECT image FROM testblob WHERE Name = ?");
pstmt.setString(1, args[0]);
RandomAccessFile raf = new RandomAccessFile(args[0],"rw");
ResultSet rs = pstmt.executeQuery();
if(rs.next()) {
Blob blob = rs.getBlob(1);
int length = (int)blob.length();
byte [] _blob = blob.getBytes(1, length);
raf.write(_blob);
System.out.println("Completed...");
} catch(Exception e) {
System.out.println(e);
Once I have managed to store the file, I would just like people to be able to view each members profile and then to click on a link that will have their stored c.v.
Thanks for a reply anyone

You could do this one of two ways..
using a prepaired statment, you could read in a byte array...
String sql="INSERT INTO BlobTest VALUES( ? )";
PreparedStatement ps=con.prepareStatement(sql);
ps.setBytes(1, byte[]); //Your byte array buffer from your FileUploadBean
ps.executeUpdate();or you could just use the input stream..
String sql="INSERT INTO BlobTest VALUES( ? )";
PreparedStatement ps=con.prepareStatement(sql);
ps.setBinaryStream(1, InputStream, length); //You'll have to do some work to get length
ps.executeUpdate();

Error in File uploading using jsp

I am tring to upload files to a mysql database using jsp.I have used BLOB type to store files.Iam using the JDBC driver mysql-connector-java-2.0-14-bin to connect the database with the jsp API.My problem is when i try to transfer a file of size which is less than the possible capacity through blob ,which is 1048576 bytes ( for example when a file of size 916KB is attempted to transfer) the following error is being generated.

Please help .I thank You in advance for any help .

Have you tried increasing the BLOB field greater than 1048576 or using a smaller file of say 1 or 2k as a test? There is no guarantee that the database will store the file with exactly the same size as the file on the filesystem, so the file might be more than 916k in the database.
Using BLOBs is a great way to destroy the performance of your database by the way :)

Filereference Upload - A script in this movie is causing Adobe Flash...

This appears to be a sore topic these days. I have searched and found a large number of postings with this flash player message (A script in this move is causing Adobe Flash Player -n- to run slowly. If it continues...) But I haven't found a posting where it is resolved. I am trying to provide my client with an upload script. What I have so far works on small files but results in the aforementioned error message on large files. I saw a message a few days ago that talked about writing an onEnterFrame routine in a dummy movie clip that increments a counter, but there were no details about what that code might look like. I have tried several iterations of that logic to no avail. I know I am not the only one with this problem, and I do need to find a solution. I don't think that the server php settings are the problem. Does anyone have any ideas?
Thanks in advance,
GW

Thank you, your answer was helpful. The problem was occuring before I entered the the code you referred to. But your response made me realize that the problem did, indeed, have to do with code that was running during the upload. I isolated the problem to the progress bar logic, which I suspect is not a coding error, but just too many cycles for the player to put up with during a long upload. I am now searching for another method of displaying upload status without a tight piece of code that loops a lot.
Thank you again kglad!

Upload file jsp code doesn't work? How can I debug

Hi Everyone,
I have the following jsp code that simply adds a new product to the backend database when 'Continue' button is pressed.
if( "Continue".equals(fp.getParameter("Submit")) ) {
     fp.setParameters(prodForm);
     prodForm.setCreateBy(currentUser.getUserID());
     prodForm.save();
     String filename = fp.getFilename("file");
          if( filename != null ) {
          // a file was uploaded
          // set the path to save it
          fp.setFilePath(PHYSICAL_PATH + "uploads\\");
          // we will change the filename to make sure it is unique
          // need to keep the file type
          String fileType = "";
          try { fileType = filename.substring( filename.lastIndexOf(".") ).toLowerCase(); }
          catch( Exception e ) { fileType = ""; }
          fp.saveFile("file", "POS_" + prodForm.getProductID() + fileType);
          prodForm.setSketch("POS_" + prodForm.getProductID() + fileType);
          prodForm.save();
     db.close();
     response.sendRedirect("index.jsp");
     return;
}The code works fine but the upload doesn't work. This is the upload part of the above code:
String filename = fp.getFilename("file");
          if( filename != null ) {
          // a file was uploaded
          // set the path to save it
          fp.setFilePath(PHYSICAL_PATH + "uploads\\");
          // we will change the filename to make sure it is unique
          // need to keep the file type
          String fileType = "";
          try { fileType = filename.substring( filename.lastIndexOf(".") ).toLowerCase(); }
          catch( Exception e ) { fileType = ""; }
          fp.saveFile("file", "POS_" + prodForm.getProductID() + fileType);
          prodForm.setSketch("POS_" + prodForm.getProductID() + fileType);
          prodForm.save();
     db.close();
     response.sendRedirect("index.jsp");So if the file browser, <input type="file" name="file">, has a file, then it saves the file in the upload folder and saves the filename in the database. But it doesn't work, it doesn't save the file in the upload folder nor it saves the filename in the database. I am new to java and jsp so could you tell me what error checking or deguging I can do in jsp to spot the problem.
Thanks,
Zub

where u write the code to upload the file
to server end?

Multiple file upload in jsp with out using �FILE� type filed.

I have an applet that is used for multiple file selection, It allows drag and drop functionality also. The problem is once the user selects multiple files it has to get uploaded to the server. Since it�s not part of a file type component while submitting the form we won�t get the file contents.
We can use multipart api for uploading files, but if the file selected by the user is not by the file type filed the file contents won�t come as part in the jsp submission and I can�t assign the file names selected by the user through the applet to any FILE (hidden ) type in jsp .
Please give a solution�

We can use multipart api for uploading files, but if the file selected by the user is not by the file type filed the file contents wont come as part in the jsp submission and I cant assign the file names selected by the user through the applet to any FILE (hidden ) type in jsp .Well i think thats a wrong notion which you have...
you can very well get non-file type field data & file item data from a multipart form.
Anyways,Letz checkout a simple example(refer to the below Code-snippet down below) which can do that task for us and it uses commons-fileupload & commons-io libraries.

NOTE:* Do not forget to add latest versions of commons-fileupload.jar & commons-io.jar in your classpath.You might get few warings due some issues with regards to generics please neglect them.
and it is not certain that you ought to use commons libraries for this there are many other alternative solutions available by which you can implement a similar functionality.
Hope this might help !!! if that does do not forget to assign/share duke dollars which you have promised :)
