File upload in Linux Platform

Hi,
I have a web application with file upload , which is working fine in my local machine(Windows platform). But when I deploy the .war file in Linux based system, the file upload option is not working. I have used the following in my jsp
page.
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="org.apache.commons.fileupload.DiskFileUpload"%>
<%@ page import="org.apache.commons.fileupload.FileItem"%>

I have given all (rwx) the permissions to the folder
to which i am uploading the files.it's having a problem with the TEMP dir.

File getName on Linux platform

Hello, I am trying to utilize the Jakarta commons upload component. When I try to run the following locally, it works:
while(i.hasNext()) {
     FileItem item = (FileItem)i.next();
     File fullFile = new File(item.getName());
     logger.info("Name is " + item.getName());
     File savedFile = new File(getServletContext().getRealPath("/"), fullFile.getName());
     logger.info("SavedFile is " + savedFile.toString());
     item.write(savedFile);
}However, when I deploy this to a Linux server, it doesn't work properly since the fullFile.getName() line is returning the full path and not just extracting the file name. I read that is because Linux allows the '\' and such in filenames. Is there a way around this?

Not sure if you got an answer but I just ran into this issue too. The issue is that the \ character is valid in a file name on Linux.
What I ended up doing is translating the \ character to / in the path. To get the name then you have to create a File object with the translated name then us the getName() method.
while(i.hasNext()) {
     FileItem item = (FileItem)i.next();
     File fullFile = new File(item.getName());
     logger.info("Name is " + item.getName());
// I added these three lines and changed the object in the savedFile instantiation to tempFile
String tempName = fullFile.getName();
tempName = tempName.replace('\\','/');
FIle tempFile = new File(tempName);
     File savedFile = new File(getServletContext().getRealPath("/"), tempFile.getName());
     logger.info("SavedFile is " + savedFile.toString());
     item.write(savedFile);
}

11.3 File Upload Extension

Since upgrading to 11.3 we're unable to install the file upload extension for firefox (ESR 24.5) on OS X (tried 10.8 and 10.9 - the extension works fine in win7). The link "Install the Novell File Upload extension to upload directories" is there but clicking doesn't do anything. It was working under 11.2.4, but hasn't worked since we upgraded to 11.3. Has anyone else run into this and found a solution?

Whilst I think you're correct the documentation needs updating since it
currently implies that whilst IE is supported on Windows (well duh!) and
Firefox 26.0 and 27.0 on Windows and Linux, Firefox ESR 17.0 and 24.0
are supported on all platforms due to absence of Windows and/or Linux
qualifiers.
From
https://www.novell.com/documentation...uirements.html
--begin--
The following web browsers are supported:
* Internet Explorer 8 (32-bit only) on Windows Vista, Windows 7, Windows
Server 2003, Windows XP, Windows Server 2008, and Windows Server 2008 R2
* Internet Explorer 9 (32-bit only) on Windows Vista, Windows 7, Windows

Windows Server 2003, Windows XP, Windows Server 2008, Windows Server
2008 R2, Windows 8, and Windows Server 2012
IMPORTANT:
* Internet Explorer versions prior to version 8 are not supported.
* Internet Explorer 11 is not supported; there are a few known issues
related to the support of this version of Internet Explorer in ZENworks.
* Firefox ESR version 17.0 and 24.0
* Firefox version 26.0 and 27.0 (including any patches) on Windows and
Linux devices

I'll report it (along with missing CSS formatting and some broken links
I just found).

JSP Uploader on Linux Issue

Hi.
I have a JSP uploader. This works fine on Windows platforms. The linux version works well too, but only with text files. Any other file (.gpeg, .odt, .pdf etc) get corrupted in some way or another on uploading.
Kindly look at the code involved and help me out. Thanks.

Error on File upload. Error processing wwv_flow.accept.

Hi,
I'm developing an application to upload and download files using Oracle XE 10g and APEX 3.2.0.00.27 on OS Windows XP.
The file upload page is very simple: one file browse item, a submit button and a report based on the wwv_flow_files table.... and an extra button to save the uploaded files in the DB.
Sometimes (almost everytime) when I press the submit button, the wwv_flow.accept process fails and I'm redirected to a page saying Internet Explorer cannot display the webpage.
I'm forced to refresh the page and then I get the following message:
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
Error ERR-7621 Could not determine workspace for application (:) on application accept.
I recreated the same page in the apex.oracle.com environment and it works, but it fails in my local environment.
I have read some posts int his forum, but I haven't found an answer yet.
Please help!!!

Can anyone point me to a standalone version of OHS for linux x86-64? I'm having troubles finding this, it doesn't appear to have installed with 11g Enterprise Edition and I cannot find it in the available packages when I re-run the installer. I'm running 11g EPG now and want to convert to Apache.

Running a perl shell command through a java program on linux platform

p.waitFor();
BufferedReader in=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line=in.readLine())!=null)
System.out.println(line);
but it doesn't output anything even if i tried to print the output to a file
i'm trying to execute this program on linux platform but its working properly on a windows platform
thx

String[] cmd={"perl","AraMorph.pl"," </home/ahmed/in.txt"," >/home/ahmed/ast.txt"};

p.waitFor();
String str2=p.getInputStream().toString();
System.out.println("==================================="+str2);
and it still outputs nothing but goes in something like infinite loop or as assumed in the article u suggested a deadlock but even all solutions to all pitfalls didn't succeed

File Upload problem: JSF, IBM WPS and Portlet - Please HELP Vey Very Urgent

I want to upload a file from the front end using JSF and Portlets deployed on IBM WebSphere Portal.
I have used Apache's commons file upload functionality as the file upload provided in JSF doesnot work with portlets and the action event is not invoked If I keep enctype="multipart/form-data". So I included 3 forms in my Faces JSP file.
1) h:form = For displyign error message on screen
2) html:form = Include the enctype="multipart/form-data" and the input type file for uploading. And a submit button
3) h:form: Here I have a command link which is remotely excuted on click of sumit button in my html form. This is to invoke the action event in the pagecode to get the bean value from the context.
Now in the my doView method in the portlet, isMultipartContent(httpservletrequest) always returns null as the content type is text/html and not multipart. Onclick of the submit button in the the html form I am calling a javascript function which sets the __LINK_TARGET__ to the command link in the 3rd h:form which will call the page code.
The problem here is action is invoked only when I return false from the above javascript else it will trigger for the first time and from second time onwards it will not invoke the action event in the pagecode method. Whent the javascript function returns false, the content type is always text/html. However if I return "true" from the javascript the content type is multipart/form-data, but the action is not triggered for the second time. So basically when the javascript functions returns true, for the first click everything works perfectly. When it returns false, the content type is text/html, but the action is invoked in the page code every time.
Returning always true would solve my problem with the content type, but the action with the command link will not get invoked always as its some type of problem with h:commanLink :(.
I guess I gave too much info. Heres my code stepby step.
Can somebody please tell me , how I should also invoke the action in the page code and get the content type as "multipart/form-data" at the same time.

one more question. Is there a way where I can submit two forms ?
Thats is submit 2nd form only when the first form is submitted.
I tried this it works.
function formSubmit(){
document.form1.submit();
alert();
document.form2.submit();
But If I dont put an alert(basically it disables the parent page) in between, only the second form is submitted.
If I put a delay of say 3 seconds in between then it will throw a SOCKET CLOSED error in the code triggered due to first form submit.
Thus disabling the paresnt page for a few seconds is reolving my problem.
Any ideas ?
Well Basically when the Alert pop's up the parent page "STALLS" and thus the form2 does not submit till I click on OK, Is there a way I can stall the browser/Parent JSP page using JAVA SCRIPT ??

Reliable file upload using JDev, AS and other

Hello,
I'm not sure this is the right place to post this message, sorry if I was wrong to put it here.
The question is our company is developing software, for active data exchange with other systems. We decided to exchange in xml format, by means of both web services and web interface (so that exchange could happen both automatically and on user request). We use JDev to develop, Oracle AS to deploy application. Systems we exchange can use various platforms, in fact, it doesn't matter what exactly they use. The question is we need a reliable way to exchange large (sometimes small, but can be 1Gb or, for example, 10Gb) files, maybe with appropriate security, so that it could continue if something happens with network connection.
One simple decision is to have a web service that accepts, for example, 100K at a time, and another service continuously calls it until file is transfered. So it can check response code. But are there better decisions? I think, there are libraries or smth like this?
Thanks in advance, believe, it's a right place to get help.

Another, simpler (we think), such package is Jenkov HTTP Multipart File Upload. It's a servlet filter which can work in front of both servlets and JSP's. The servlet filter parses the uploaded file and stores it temporarily on the servers disk. When the servlet or JSP executes afterwards, it can obtain all the information about the file, from the request attributes. There is a decent manual for HTTP Multipart File Upload on the website.
Just search for "Jenkov HTTP Multipart" on Google and you'll find it. HTTP Multipart is free, open source, Apache Licsense.

File Upload issues

There is a file upload that I have and I am getting an
error...
Notice: Undefined variable: file_list in
C:\vhosts\mysite\upload\index.php on line 20
On line 20 in my php page happens to be the following code
that is giving an error...$file_list .= "<option value=\"$file\"
>$file</option>";
<?php
#for windows...
$dirname = $_SERVER['DOCUMENT_ROOT'].'/_assets/professor/';
//$dirname = "C:\\wamp\\www";
#(for Linux... $dirname = "user/local/apache/bin";)
$dir = opendir($dirname);
while(false != ($file = readdir($dir))){
if(($file != ".") and ($file != "..")){
$file_list .= "<option value=\"$file\"
>$file</option>";
closedir($dir);
?>
This is what is in the body...

What that's telling you is that you're adding a value to a
variable that
doesn't yet exist. In your case, it probably doesn't matter,
but using
undefined variables is a potential security risk. To
eliminate the
warning - and the risk - declare $file_list before using it:
$file_list = '';

File Uploads using stored procedures

Hello, I'm quite new here, but I have a question that I've been butting my head against for the past day. Here goes.
We need to upload a file using a stored procedure (PL/SQL procedure.)
The two things I have found that work are
1) Having oracle do the file handling (using bfiles) in the procedure
2) using an insert statement directly to upload the file contents into a blob.
The platform is php (Oracle instant client) and I will show some code examples.
1) is unworkable because Oracle will not have direct access to any files.
2) is fine, but we would prefer to use a procedure so as to abstract what exactly goes on and possibly other operations away from the php and the framework.
What worked:
1)
CREATE OR REPLACE PROCEDURE php_upload_file (file_name in varchar2, canonical_name in varchar2, owner in number, file_id IN OUT number)
AS
src_loc bfile:= bfilename('DOC_LOC',php_upload_file.file_name);
dest_loc BLOB;
begin
insert into files values(owner,canonical_name,empty_blob(),files_seq.nextval) returning files.data, files.file_id
into dest_loc, file_id;
dbms_lob.open(src_loc,DBMS_LOB.LOB_READONLY);
DBMS_LOB.OPEN(dest_loc, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.LOADFROMFILE(
dest_lob => dest_loc
,src_lob => src_loc
,amount => DBMS_LOB.getLength(src_loc));
DBMS_LOB.CLOSE(dest_loc);
DBMS_LOB.CLOSE(src_loc);
COMMIT;
end;
'DOC_LOC' is a directory I've set up that the user has access to.
Interfacing with PHP this just looks like
oci_parse($conn,"BEGIN php_upload_file('{$uploadfilename}','{$propername}',{$ownerid},:file_id); END;");
Dead simple, right?
I also do a bind command to pull out 'file_id' so I know the id that was just inserted.
The other solution is
$contents = file_get_contents($_FILES["uploadedfile"]["tmp_name"]);
$lob = oci_new_descriptor($conn, OCI_D_LOB);
$stmt = oci_parse($conn,
"INSERT INTO files (employee_id, filename, data, file_id) VALUES(175,'"
.$_FILES["uploadedfile"]["name"].
"', empty_blob(), files_seq.nextval) RETURNING file_id, files.data INTO :file_id, :src_contents");
where :src_contents is binded to a lob and :file_id as before is binded to an INT:
oci_bind_by_name($stmt, ':src_contents', $lob, -1, OCI_B_BLOB);
oci_bind_by_name($stmt, ':file_id', $insert_id, -1, SQLT_INT);
oci_execute($stmt,OCI_DEFAULT);
In this case the last thing I do before the commit is
$lob->save($contents);
Both work fine, but what I need is this
$contents = file_get_contents($_FILES["uploadedfile"]["tmp_name"]);
$lob = oci_new_descriptor($conn, OCI_D_LOB);
$stmt = oci_parse($conn,"BEGIN do_upload_file(:src_contents,'{$propername}',{$ownerid},:file_id); END;");
oci_bind_by_name($stmt, ':src_contents', $lob, -1, OCI_B_BLOB);
oci_bind_by_name($stmt, ':file_id', $insert_id, -1, SQLT_INT);
oci_execute($stmt,OCI_DEFAULT);
$lob->save($contents);
oci_commit($conn);
this omits error conditions (such as on $lob->save ... etc.) it is simplified.
The content of the procedure I changed as follows, but it seems untestable.
CREATE OR REPLACE PROCEDURE do_upload_file (src_contents IN OUT blob, canonical_name in varchar2, owner in number, file_id IN OUT number)
AS
dest_loc BLOB;
begin
insert into files values(owner,canonical_name,empty_blob(),files_seq.nextval) returning files.data, files.file_id
into dest_loc, file_id;
dbms_lob.open(src_contents,DBMS_LOB.LOB_READONLY);
DBMS_LOB.OPEN(dest_loc, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.COPY(dest_lob => dest_loc,
src_lob => src_contents
,amount => DBMS_LOB.getLength(src_contents));
DBMS_LOB.CLOSE(dest_loc);
DBMS_LOB.CLOSE(src_contents);
COMMIT;
end;
I don't get errors because I cannot figure out a way to run this procedure in my PL/SQL environment with valid data. (I can run it with a blank blob.)
But when I work out the order of what's going on, it doesn't make sense; the commit in the procedure is before the $lob->save(...) and thus it would never save the data... nonetheless it should at least create a record with an empty blob but it does not. What is wrong is beyond the error level that seems to be supported by PHP's oci_error function (unless I have not discovered how to turn all errors on?)
In any case I think the logic is wrong here, but I'm not experienced enough to figure out how.
To test it I would need to create a driver that loads an external file into a blob, and passes that blob into the procedure. Trouble is, even if I make a blob and initialize it with empty_blob() it treats it as an invalid blob for the purposes of the dbms_lob.copy procedure.
If someone has solved this problem, please let me know. I would love to be able to do the file upload with just a single procedure.

Thanks. In my estimation that is exactly the issue. But that doesn't help with a resolution.

Issues with file upload in flex mobile application (sharepoint as backend)

Hello,
I am working on flex mobile application for android platform for which we are having sharepoint as a backend.
(Flex SDK 4.6 and AIR 3.9)
Issue which we are facing is as follows:
We are communicating with the backend server using webservices: example:
<s:WebService id="kWebService" wsdl="http://www.kservice.net/kdatabaseservice.asmx?WSDL" >
            <s:operation name="AddPost"
                         resultFormat="object"
                         result="addPostResult(event)"
                         fault="postsfaulterr(event)" />
</s:WebService>
Above services are working fine but we are facing issue with one service which is related to file upload.
File upload for <10 MB is working fine but when we try to upload larger file on server it fails to process.
We are sending bytearray to the backend and backend code is writing those bytearray into file.
We have tried many ways to overcome from this situation. like we have checked configuration for file upload size on server , we have tried wcf services as well. Please help us on this criticle point as soon as possible
Thanks

What do you mean that my video saves the contents int he server and not in transparent table? I save the data into a temporary database table so it can be accessed by the parent WDA session. From there the WDA session can do whatever it wants with it. What do you mean by transparent table - that would be a database table. Do you actually mean internal table? if so, just read the data from the temporary database table into memory.

File.upload on Air SDK for iOS devices failed to send http request to server.

I am trying to use ActionScript's File.upload to upload a file on Air SDK for iOS8 environment, but the File.upload does not work properly. No handler about the file upload is executed after File.upload is invoked, and no exception is caught. When I check the network traffic of the server side, I found that no http request even hit the server after File.upload is executed. The code snippet here is very simple.
private var file:File;
private var dir:File;
//This method is executed to create a file and upload it when the Upload Button is pressed.
protected function OnUploadButtonPressed(event:MouseEvent):void{
var str:String = 'This is test';
var imageBytes:ByteArray = new ByteArray();
for ( var i:int = 0; i < str.length; i++ ) {
imageBytes.writeByte( str.charCodeAt(i) );
try{
dir = File.applicationStorageDirectory
var now:Date = new Date();
var filename:String = "test" + now.seconds + now.milliseconds + ".txt";
file = dir.resolvePath( filename );
var stream:FileStream = new FileStream();
stream.open( file, FileMode.WRITE );
stream.writeBytes( imageBytes );
stream.close();
file.addEventListener( Event.COMPLETE, uploadComplete );
file.addEventListener( IOErrorEvent.IO_ERROR, ioError );
file.addEventListener( SecurityErrorEvent.SECURITY_ERROR, securityError );
file.addEventListener(ErrorEvent.ERROR, someError);
file.addEventListener(ProgressEvent.PROGRESS, onProgress);
file.upload( new URLRequest("http://10.60.99.31/MyPath/fileUploadTest.do"));//This line does not work. No handler is executed. No http request hit the server side.
} catch( e:Error ) {
trace( e );
//Complete Handler
private function uploadComplete( event:Event ):void
trace( "Upload successful." );
//IOError handler
private function ioError( error:IOErrorEvent ):void
trace( "Upload failed: " + error.text );
//SecurityError handler
private function securityError(error:SecurityErrorEvent):void{
trace( "Security error:" + error.text );
//Other handler
private function someError(error:ErrorEvent):void{
trace("some error" + error.text);
//Progress handler
private function onProgress(event:ProgressEvent):void{
trace("progressHandler");
When executed on Air Simulator, it works fine as expected, and the file is successfully uploaded to the server. But When executed on iOS devices(in my case, iPad), as I explain early, no handler about the file upload is executed, and no the http request even hit the server. So I think the problem may be in the client side. It seems that the Air SDK for iOS just failed to send the http request for some reason.
To make my problem more clear, I list my environment below:
Development Environment: Windows7 (64bit) / Mac os 10.9.4 (Tested on OS platforms.)
IDE: Flash Builder 4.7
Air SDK: 3.8 / 16.0.0 (After I updated to the lastest Air SDK 16.0.0 , the problem still exists.)
Application Server: Tomcat7 + Spring
Target OS: iOS 8
I have been struggling for this for days. So I really appreciate it if anyone has any idea about this.
Thanks in advance.

Hi bluewindice ,
As you have quoted ( ActionScript's File.upload does not work on Air SDK for iOS devices ) , this issue has been replicated at our end, and our team will be working on it.
Thanks,

When I use FTPFire the .htaccess file uploads as hidden. How do I unhide it once it is uploaded?

My .htaccess file shows live on my c drive... When I upload it to my web host, it loads as hidden...
How can I unhide it once it is uploaded?

That is the purpose of that file. On Linux a file that start with a dot is a hidden file and there is no need to see that file anyway because it is meant for controlling the server behavior. I assume that FireFTP has a setting to show hidden files that you need to enable if you do not see the file.

Tomcat file upload

Hi, I'm having a problem with file upload.
I've try to use oReilly classes, but I've had problems.
So I've try to use a small package from com.bigfoot ( he's probably a student) for multipart form.
All works well with tomcat 4.0 on win2k.
When I deploy the application under Linux 7.2, Tomcat 4 and Apache ... problems begins :-(((((
During ServletInputStream reading, I think, something goes wrong. Some bytes are read ... then the stream seems to empty ... and the reading process crashes.
What can I do ????

I'm sorry I've change my account so look the newer message from alexdonato.
