Upload file in unix

Hi Everyone
Mukul, in your blog, i was following the code to Upload file to Application server using OAFileUploadBean instead of Database. What exactly are we doing here?
1) Are we taking a file from one location in the unix box and copying into another location?
2) What is fileuploadBeanId in the following syntax.
DataObject fileUploadData = (DataObject) pageContext.getNamedDataObject(fileuploadBeanId);
3) What needs to be given for UPLOAD_FILE_NAME in the below syntax.
String uFileName = (String) fileUploadData.selectValue(null, "UPLOAD_FILE_NAME");
It would be great if you can answer me these questions. Thanks a lot in advance.

Hi,
I havn't gonr through this article so I can reply only first two questions:
1. We will take the file from client machine and then this will be uploaded to Unix box.
2. This is the Handle for the File Upload bean which you may be using to browse the file.
I will check this article and update the thread for third point.

Uploaded Files stored in Oracle 10G database or in Unix File system

Hey All,
I am trying to understand best practices on storing uploaded files. Should you store within the database itself (this is the current method we are using by leveraging BLOB storage) or use a BFILE locator to use the files system storage (we have our DB's on UNIX) . . .or is there another method I should be entertaining? I have read arguments on both sides of this question. I wanted to see what answers forum readers could provide!! I understand there are quite a few factors but the situation I am in is as follows:
1) Storing text and pdf documents.
2) File sizes range from a few Kb to up to 15MB in size
3) uploaded files can be deleted and updated / replaced quite frequently
Right now we have an Oracle stored procedure that is uploading the files binary data into a BLOB column on our table. We have no real "performance" problems with this method but are entertaining the idea of using the UNIX file system for storage instead of the database.
Thanks for the insight!!
Anthony Roeder

Anthony,
First word you must learn here in this forum is RESPECT.
If you require any further explanation, just say so.
BLOB compared with BFILE
Security:
BFILEs are inherently insecure, as insecure as your operating system (OS).
Features:
BFILEs are not writable from typical database APIs whereas BLOBs are.
One of the most important features is that BLOBs can participate in transactions and are recoverable. Not so for BFILEs.
Performance:
Roughly the same.
Upping the size of your buffer cache can make a BIG improvement in BLOB performance.
BLOBs can be configured to exist in Oracle's cache which should make repeated/multiple reads faster.
Piece wise/non-sequential access of a BLOB is known to be faster than a that of a BFILE.
Manageability:
Only the BFILE locator is stored in an Oracle BACKUP. One needs to do a separate backup to save the OS file that the BFILE locator points to. The BLOB data is backed up along with the rest of the database data.
Storage:
The amount of table space required to store file data in a BLOB will be larger than that of the file itself due to LOB index which is the reason for better BLOB performance for piece wise random access of the BLOB value.

Upload the file in Unix at some specified directory

Hi,
I have to store some file in Unix Box at some specified location through OAF Page.
I have seen all the threads, they work for storing the file in Database. I have done that previously and that works fine.
Please let me know the approach and the way I should follow to store the file in Unix.
Appriciate for an early reply.
Thanks
Anoop

Anoop,
What do you mean by the link has nothing? Do you mean that the link doesn't work?
FIle Upload
I can see it.
If it still doesn't, try searching the forumns for the thread with subject "FIle Upload" posted by "user526196".

Interface Mngr: Option for Uploading file from presentation or unix server

Hi all,
I want to upload file through interface manager where the file can be on the presentaion server or the unix server. How do i achieve the same? I need to create parameters for 'Filename' and 'Unix Filename'. Either of the 2 will be chosen at a time. But how do i retrieve the respective file?

Hi!
For handling a file on the apllication server (unix), you have to use the OPEN DATASET, CLOSE DATASET commands.
For handling the files on the presentation server (local PC), you have to use the upload/download method (GUI_UPLOAD, GUI_DOWNLOAD function elements).
You can make 2 parameters in your ABAP program like this:
PARAMETERS: p_f_app LIKE rlgrap-filename.
PARAMETERS: p_f_pre LIKE rlgrap-filename.
both is filled - error
IF NOT p_f_app IS INITIAL AND
NOT p_f_pre IS INITIAL.
MESSAGE E001(ZERROR).
ENDIF.
both is empty - error
IF p_f_app IS INITIAL AND
p_f_pre IS INITIAL.
MESSAGE E002(ZERROR).
ENDIF.
IF NOT p_f_app IS INITIAL. "application server
open dataset...
ENDIF.
IF NOT p_f_pre IS INITIAL. "presentation server
call function 'gui_upload'...
ENDIF.

How to SCAN uploaded files for VIRUS in APEX

part 1:
Goal:
Do a virus scan of the uploaded file from APEX application prior to storing the file in custom tables.
The process:
Followed the document from www.developer.com:
Implementing an Anti-Virus File Scan in JEE Applications
By Vlad Kofman
Go to page: 1 2 3 Next
This article will discuss one of the ways to implement antivirus file scanning in Java, particular in the JEE applications. Viruses, Trojan Horses, and different malware and spyware are a real problem for current computer environments, and especially for the Windows operating system. If you are designing any application in Java that has a requirement to be able to upload external files, you have a potential security risk. By uploading, I mean any way to get the external file inside of the corporate firewall be it via HTTP protocol or any other means. It is quite common to have this type of requirement in an enterprise application and with Java being one of the most popular web development platforms, it is unfortunate that this type of gaping security risk is quite often overlooked.
Java's Development Kit (JDK) does not have any means to do the antivirus scan right out of the box. This is primarily because Java is a programming language, and does not have any virus scanning packages. Furthermore, anti-virus software is not Sun's area of expertise or business model. Developing this type of software (or Java package), and more importantly maintaining it, would be a huge task for Sun. Mainly because viruses are constantly evolving and keeping virus definitions up-to-date is a daunting task. Large companies such as McAffee, Symantec, or Zone Labs develop virus detecting and combating products and spend a lot of resources to maintain them.
Application Environment
To implement a virus file scan in Java, a third-party package needs to be used. For the purposes of this article, I will use Symantec Scan Engine (SSE) package, which comes with Java APIs. This package is an application that serves as a TCP/IP server and has a programming interface and enables Java applications to incorporate support for content scanning technologies. For this article, I used Symantec Scan Engine 5.1, which is available as a Unix or Windows install.
If you are using an anti-virus package from the different vendor, you will need to investigate what kind of APIs are available; however, the general approach should be similar. Also, note that my implementation can be used with JEE technology and any modern MVC framework such as Struts or Spring.
The architecture is as follows: A server machine needs to have SSE running at all times. This can be the same machine that hosts your Application Server, but in an enterprise environment this should be a different machine. The Default Port needs to be open through the firewall to allow communication with the scan engine. All JEE applications that need to do file scanning can talk to the SSE server machine through a default port. Also, multiple applications running on different application servers can re-use the same scanning server. For more information, you should refer to the Symantec Scan Engine (SSE) Installation Guide, available on the Symantec web site.
When an external file that needs to be scanned is sent to the SSE via its programming interface (Java APIs using the default port), before any other operation on the file is performed, the SSE returns a result code. For instance, a file is uploaded by an external user into the web email type application as an attachment; then, the SSE API is invoked by the application and the return code of pass or fail determines the outcome of the upload and whether that email can actually be sent. If you have an account on Yahoo mail, you probably have seen that Yahoo is using Norton Antivirus to scan all attachments, although no Java.
Click here for a larger image.
Figure 1: Screen shot from Yahoo
For details on the Scan Engine Server Installationm please see the Symantec Scan Engine (SSE) Implementation Guide from Symantec.
Here are some key things to remember about SSE:
•     Java 2 SE Runtime (JRE) 5.0 Update 6.0 or later must be installed on the server before the SSE installation is done.
•     After installation, verify that the Symantec Scan Engine daemon is running. At the Unix command prompt (if it's a Unix install), type the following command:
ps –ea | grep sym.
A list of processes similar to the following should appear:
o     5358 ? 0:00 symscan
o     5359 ? 0:00 symscan
If nothing is displayed the SSE process did not start.
If the SSE process did not start, type the following command to restart SSE:
/etc/init.d/symscan restart
•     Keeping the virus definition up to date is the most important task and if new updates are not installed, the whole scan becomes ineffective. Symantec automatically downloads the most current file definitions through LiveUpdate. Please make sure that firewall rules are in place to allow the host server to connect to the Symantec update service.
Project Setup
For the purposes of this article, I included a wrapper for the Symantec SSE APIs, av.jar, which has Symantec Java APIs and serves as a client to the SSE server and takes care of all communications with the server. Please refer to the download source section. The av.jar should be included in the Java CLASSPATH to work with the SSE. This jar contains a class called AVClient that takes care of actually sending the files to SSE as byte arrays and returning the result.
In my project setting, I added three variables to be accessed via the System.getProperty mechanism. For example:
AV_SERVER_HOST=192.168.1.150
AV_SERVER_PORT=1344
AV_SERVER_MODE=SCAN
The AV_SERVER_HOST is the host name or IP of the machine where Scan Engine is installed.
The AV_SERVER_PORT is the port where Scan Engine listens for incoming files.
The AV_SERVER_MODE is the scan mode which can be:
•     NOSCAN: No scanning will be done (any keyword that does not start with "SCAN" will result in ignoring the call to the Scan Engine and no files will be transferred for scanning).
•     SCAN: Files or the byte stream will be scanned, but the scan engine will not try to repair infections.
•     SCANREPAIR: Files will be scanned, the scan engine will try to repair infections, but nothing else will be done.
•     SCANREPAIRDELETE: Files will be scanned, the scan engine will try to repair infections, and irreparable files will be deleted.
Note: For the file stream (byte array) scanning, the only meaning full values are "SCAN" and "NOSCAN".
Using the SSE Scanning Java APIs
In any class where scan is required, call the scanning API provided in the AVClient object located in the av.jar. The AVClient object will establish connection to the Scan Engine server and has the following APIs:
Figure 2: The significant APIs for the communication with to the Scan Engine Server.
If scanning a file on the file system, in SCAN only mode, use the call that accepts filename only.
If scanning a file on the file system, with SCANREPAIR or SCANREPAIRDELETE, use the call that accepts input and output file names.
If scanning an in-memory file (byte array), use the call accepting byte array.
For example:
import com.av.*;
Initialize setup parameters:
static String avMode =
(System.getProperty("AV_SERVER_MODE") != null)
? (String) System.getProperty("AV_SERVER_MODE") : "NOSCAN";
static boolean scan = avMode.startsWith("SCAN");
static String avServer =
(String) System.getProperty("AV_SERVER_HOST");
static int avPort =
Integer.parseInt( (String) System.getProperty("AV_SERVER_PORT"));
Scan check example for an in-memory file byte array:
public void scanFile(byte[] fileBytes, String fileName)
throws IOException, Exception {
if (scan) {
AVClient avc = new AVClient(avServer, avPort, avMode);
if (avc.scanfile(fileName, fileBytes) == -1) {
throw new VirusException("WARNING: A virus was detected in
your attachment: " + fileName + "<br>Please scan
your system with the latest antivirus software with
updated virus definitions and try again.");
Note that if you are using this code inside of the MVC handler, you can throw a custom VirusException and check for it in the calling method and perform any necessary cleanup. I have included the class in the AV Jar as well.
For example:
catch (Exception ex) {
logger.error(ex);
if (ex instanceof VirusException) {
// do something here
else {
// there was some other error – handle it

d)     my2.java – This is the class file I wrote to test that I am able to send a file and scan it and see the output in the JDEVELOPER. In this case the file is stored on the filesystem of the client machine. JDEVELOPER should be able to see the file.
NOTE:
“EICAR.com” is the test file downloaded from Symantec site to test a non malicious virus file. I n order to be able to test it like this, the Antivirus program running on your machine should be disabled, or else Antivirus will kick in and delete the file. In the first place you will not be able to download the test virus file either with anti virus running on the machine you are downloading to.
package com.av;
import java.io.*;
public class my2 {
static int my_return = 0;
* @param fileBytes

public static int scanfile(String fileName){

int avPort = 1344;
int the_return = 0;
if (scan) {

e)     Then finally we have my1.JAVA, which takes the filename, and it’s contents in the bytes form and scans the file. The reason for this method is we are not storing the file on the filesystem, it is read into the memory and only if it is clean, it is put into the database or else notify the user.

public static byte[] getBytesFromFile(File file) throws IOException {

// Get the size of the file
long length = file.length();
// You cannot create an array using a long type.
// It needs to be an int type.
// Before converting to an int type, check

if (length > Integer.MAX_VALUE) {
// File is too large
// Create the byte array to hold the data
byte[] bytes = new byte[(int)length];
// Read in the bytes
int offset = 0;
int numRead = 0;
while (offset < bytes.length
&& (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
offset += numRead;
// Ensure all the bytes have been read in

throw new IOException("Could not completely read file "+file.getName());
// Close the input stream and return bytes
is.close();
return bytes;
// public static void main(String[] args) throws Exception {
//System.out.println("Hi there in Main");
// File file = new File() ;
// byte[] b1 = getBytesFromFile(file);
//System.out.println(b1);
// my_return = scanfile(,b1);
//System.out.println(my_return); }
Finally , you have the exceptions file,
e) package com.av;
public class VirusException
extends Exception {
public VirusException() {
super();
public VirusException(String text) {
super(text);
Once you have all these classes, you can use JDEVELOPER , to load these classes into the database: This is as follows:
Right click on the project, which has all these classes.
NEW -> deployment profiles -> load java and stored procedures.
When you are created deployment profile, you have to specify,
Loadjava options.
-f, -v (check the check boxes)
Under privileges:
-s – specify database schema these classes are loaded into
-s – create sysnonym check box
-g – grant to public or any specific users per your policy.
Under Resolver,
-r and –o (check the check boxes)
I accepted the default name storedproc1. Then you right click on the storedproc1.deploy, deploy to whichever database connection you created.
And then, In order to access this java class we need a pl/sql wrapper as follows:
create or replace package my1 is
function mycheck (pfilename in varchar2, psize in number)
return number;
end my1;
create or replace package body my1 is
     function mycheck (pfilename in varchar2, psize in number)
return number is
language java
     name 'com.av.my1.scanfile(java.lang.String, byte[]) return int';
     end my1;
And the code is invoked from sql plus as follows:
Select my1.mycheck(“filename”, “filebytes”) from dual;
One important catch in the above method is to send the filename and filecontents in bytes form. In order to send the file contents as filebytes, you will need another java class and load into the data base as described above.

And you create the pl/sql wrapper again as follows:
create or replace FUNCTION TOBY (pfilename in varchar2) RETURN VARCHAR2 iS
language java name
'ReadFileIntoByteArray.chk_file(java.lang.String) return byte[]';
And you call the function from sqlplus as follows:
Sql>Set serveroutput on size 20000;
Sql> call dbms_java.set_output(20000);
Sql> Select toby(“filename”) from dual; --
this file should be accessible, I mean you will not be able to send a file on your pc, from sql plus as sql/plus is running on your db server.
You will be able to see the output in sql plus:
If you are running it from the APEX:
When we use file browser widget from APEX, the file is stored in APEX_APPLICATION_FILES table. And we retrieve that into a variable and pass this variable to the function as follows:
DECLARE
scan_failed EXCEPTION;
x varchar2(400);
z number;
BEGIN
select filename into x from wwv_flow_files where name = :P1_FILE_NAME;
select my1.mycheck(x,toby(x)) into z from dual;
if z = 0 then
:P1_SUBJECT:= 'PASSED';
else
:P1_SUBJECT:= 'FAILED';
end if;
:P1_SCAN_RESULT := '** Scanning File **';
IF UPPER(:P1_SUBJECT) = 'PASSED' THEN
BEGIN
:P1_SCAN_FLAG := 'PASSED';
:P1_SCAN_RESULT := :P1_SCAN_RESULT || ' ** File passed scan **';
END;
ELSIF UPPER(:P1_SUBJECT) = 'FAILED' THEN
BEGIN
:P1_SCAN_FLAG := 'FAILED';
:P1_SCAN_RESULT := :P1_SCAN_RESULT || ' ** File failed scan **';
END;
ELSE
BEGIN
:P1_SCAN_FLAG := 'UNKNOWN';
:P1_SCAN_RESULT := :P1_SCAN_RESULT || ' ** Scan Is Not Conclussive **';
END;
END IF;
--IF :P1_SCAN_FLAG = 'FAILED'
-- THEN RAISE scan_failed;
--END IF;
EXCEPTION
WHEN OTHERS THEN
DELETE from APEX_APPLICATION_FILES WHERE name = :P1_FILE_NAME;
RAISE_APPLICATION_ERROR (-20000, 'seb OTHERS error encountered - file upload not allowed. Possible virus detected !');
raise;
END;

java.io.FileNotFoundException: 07ics01/jsp/C:\Documents and Settings\s9sharma\Desktop\tt\commons-digester-1.8\commons-digester-1.8.jar (No such file or directory) where C:\Documents and Settings\s9sharma\Desktop\tt\commons-digester-1.8\commons-digester-1.8.jar is the file i am trying to upload to the directory 07ics01/jsp which is a unix directory.
Can anyone please help..

So you've copypasted this code from somwhere and are expecting our support on the code, instead of the author's support? That's sad.
I recommend you to look to the Apache Commons FileUpload API [1]. Then you don't need to write (or copypaste) a multipart parser yourself. Putting business logic in JSP files is also bad practice by the way. Use Java classes for it instead (Servlets, Filters, Beans, Utilityclasses, etc).
[1] http://commons.apache.org/fileupload/
To understand the actual code, it might help a lot to first read and understand the HTML spec about multipart request data and read the API documentations of the Java classes involved, e.g. the java.io API.

"\n" problem while downloading the file in unix environment

Hi folks,
I have some problem in uploading and downloading the file in unix environment..
This is my sample code i am using.
File userDataFile = new File("xyz".csv");
out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(userDataFile),"UNICODE"));
out.write("Name"+"\t");
out.write("Age"+"\t");
out.write("Dob"+"\t");
out.write("Contact"+"\n");
for(int i=0;i<retList.size;i++){
out.write("xyz"+"\t");
out.write("22"+"\t");
out.write("300399"+"\t");
out.write("xyzzz"+"\n");
as per this i wrote code for generating the reports. Its contains some 7k records.
Its works in Windows environment.
Some times in Windows environment if the contents size is 7000 records means
i got only the headers..
I am not getting any real records.
I am not sure.. my client is using may be an unix environment..
Please give the solutions for this..
Very thanks in advance.

Hi Jothi,
This is not an answer to your question. It is a question for you instead. I have tried to reach you on several forums regarding the HAP_DOCUMENT documentation you have.
Again, I am really sorry to contact you through a differente forum, but I really need the HAP_DOCUMENT documentation for my project.
Please send me a message to [email protected]
Thanks again.

Can i development program with EDK for uploading file to server?

Can I development program with EDK for uploading file to server?How to avoid same name of files?
Thanks!

Hi ,
thanks for the quick response.
but the problem is supppose i have a excel sheet with 16 rows and 13 columns(so data).
i am placing this file contents to appserver USING ABOVE fm.
after that i am reading the file from appserver to create SO(idoc),i need 1row-3column data and 2row-2c data.like that.
in unix we will get row data(after uploading to app server) as #mprn#2345# like this so easy to separate when reading.but in MS NT OS 1row data getting stored in different rows in Appserver.so difficult to read.
so the above mentioned FM is OS dependent or is there any way (any other FM) to get same kind of data in different OS.
PLEASE SUGGEST OTHER WISE I NEED TO CODE BASED ON OS.

Can you use command lines to copy files in UNIX to Oracle Apps

Hi! We have installed the oracle apps 11.5.0 to a unix operating system. And we use ftps to upload the rtf and xml files to the unix server. Is there any command lines we can use to copy all the rft and xml files in the server to the real location of where the report files stored without going through the XML Publisher font end through the internet explorer? Thanks for your help!

Hi,
From what you have mentioned, I believe you are writing custom xml pub report
1) Storing all your template and sample xml data file on Unix box by FTPing it. This step is not required as XML publisher picks template from XDO tables (where it is stored in CLOB), unless you are explicitly Coding to use templates from a fixed location like <CUST_TOP>/<xml_templates>
2) As part of XML setup, you need to define the template and datasource using the front end. This causes the Template and XML data (sample) to be stored in XDO tables (as clobs). This step is basically required and unavaoidable.This step can be automated using FNDLOAD tool (not sure).
Hope it helps somewhat.

UPLOAD FILE

Hi.. i did some research on loading the csv file, and its pretty cool. But I ran into this problem, I was uploading test.csv file as given here
Re: Loading a CSV file into a table(Vikas Plz)
and mainly the demo provided by Vikas.
and it works pretty well. But when my csv file gets bigger in size, although i can see the data is getting inserted into the table, but the front end session is timing out.
So I thought if i can upload test.csv to wwv_flow_files and then using UTL_FILE, i can transfer it to the unix box and then run some scripts. WHY? bcos our team is already doing this kind of thing.. load csv file to unix box and insert data of csv file to the tables. So its pretty much done.. only thing is to provide capability to upload the file to unix box.
Does it make sense? If yes.. then how can i upload file to wwv_flow_files using File browse item.
Suggestions / Ideas?

Hi Prashant,
Did you already have a look here: http://download-west.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32469/up_dn_files.htm
This provides you pretty good information how to create an upload/download application in APEX.

I cannot upload files from my macbook pro via email, etc

When I click on insert file all I see is the main menu with the folders when I select the folder it does not give me the option to open to select and upload files.
How can I rectify this?
In all honesty I am sarting to regret buying a mac, all I have been expericing is trouble. they are not major but very annoying.
I fixed it one month ago for slow boot up time, it was fixed yet it is progressively heading doen that road again helpp.
I am a university student and this thing is really annoying
Thank you for the help

Welcome to the Apple Support Communities
You can only write in NTFS drives in Windows, not OS X or Linux or any other UNIX-based system. If you want to write in NTFS drives, you have to use a third-party application as Paragon NTFS.
Another possibility you have is to format the external drive in a format that OS X can read and write in it, like HFS+ (Mac OS Extended (Journaled)), FAT32 (MS-DOS (FAT)) or exFAT, but this is longer and you need a lot of time to back up your external drive files

Online program to create a flat file on Unix

Hi All,
Good day.
I got one requirement, where I need to write a Online program that will create a flat file on Unix. The probable Unix file will be send from the selection screen, where the user selects that with a fixed length & format.
Do I need to do it with the Datasets? or is it possible to go with Upload function modules?
Please, send one example program of such kind.
Thanks,
Kal Chand

Hi,
You are going to create a flat file in the Unix Operating system which is nothing but the application server.
There are no standard function modules to write the file in the application server, so you need to use the DATA SET concept only.
1. Open Data Set file name
2. Transfer Data Set file name
3. close Data set file name
I believe this will help you to finish your requirement.
Thanks,
Mahesh.

Adobe Muse won't publish (Error uploading file)

After making simple animations using Adobe Edge Animate it seems as though none of the assets will publish with my site after importing them into Muse.
In Edge animate I saved for "web animation" and published. Then I went to muse and hit "place". I went to preview and everything works fine. When I go to publish there are always errors in uploading my assets with '.png' extensions.
Any help is much appreciated. I have completely scrapped my website and created another, reinstalled Animate and have renamed all my files, I'm not sure whats wrong here.
I got one animation working, and that can be seen here under the Photography section, but I have multiples that will be shown on my page at one time.
http://chasebodydesign.businesscatalyst.com

I get the error uploading file everytime I try publishing the animation.
