Upload file PL\SQL

Hi,
I'm writing a web application using PL\SQL procedure.
I've got one problem, how can I upload file in the database blob field?
I've found some articles (like this: http://www.acs.ilstu.edu/docs/oracle9ias/web.902/a90855/feature.htm
) that present this example,but its doesn't work:
-----------------------------FILE.HTML----------------------------------------------------------
<html>
<head>
<title>test upload</title>
</head>
<body>
<FORM enctype="multipart/form-data"
action="pls/mydad/write_info"
method="POST">
<p>Author's Name:<INPUT type="text" name="who">
<p>Description:<INPUT type="text" name="description"><br>
<p>File to upload:<INPUT type="file" name="file"><br>
<p><INPUT type="submit">
</FORM>
</body>
</html>
----------------------------------PROC PL\SQL---------------------------------------------
procedure write_info (
who in varchar2,
description in varchar2,
file in varchar2) as
begin
insert into myTable values (who, description, file);
htp.htmlopen;
htp.headopen;
htp.title('File Uploaded');
htp.headclose;
htp.bodyopen;
htp.header(1, 'Upload Status');
htp.print('Uploaded ' || file || ' successfully');
htp.bodyclose;
htp.htmlclose;
end;
--------------------------------------------END-----------------------------------------------
Any ideas?

SQL*Loader and unzipping with uploaded file

hi, everybody
i was trying to integrate some functionalities, today separated. i made a simple Apex page that uploads a file, and now i need to process that file.
is there any way to process that uploaded file and load it onto a table, just like i'd do with Sql*Loader?
in the same way, can i unzip an uploaded zip file, just like Oracle Portal 3.0.9 used to do in its contect areas with zip itens?
thanks

Hi, Ivo
about ult_compress, ok. i'll check it out.
talking about uploaded files, the only thing i've found were:
a) download an uploaded file
b) use an uploaded image to integrate in a web application.
unfortunately, i didn't find anything that could help me process an uploaded text file the way i do with SQL*Loader.
i'll keep on trying
thanx

Upload Multiple files in SQL * Loader in one session

Dear all,
I want to upload multiple files using SQL*Loader in one go. In Unix its very easy as I have a quite experience of that. Could any body tell what is a way in Windows to upload multiple files in one go while using SQL * Loader. I want to run that using DOS's Batch file.
Thanks
Ghulam

In Unix its very easy like we are putting $ sign.
sqlldr userid=?????/?????
control="/u12/cad_delta.ctl",log="/u12/full_extract/$1",data="/u12/$1",bad="/u12//full_extract/$1",errors=500,silent=feedback
Suggest for Windows? It should read all .DAT files of the Windows Folder.
Thanks

File upload use pl/sql with OAS 4082 and 8i/EE

is there any way to upload/download files (any format) from web browser use FORM and above env. Don't mention samples in OAS document, it simply doesn't work. thanks.

It says:
"+The semantics of these HTTP(S) methods is in accordance with WebDAV. Servlets and *Web services may support additional HTTP(S) methods*, such as POST.+" (my emphasis - so yes, it is supported).
Today we are using an Appserver with HTTP mod_plsql, the code for the form looks like:
htp.formopen (
curl => 'FileUpload',
cmethod => 'POST',
cenctype => 'multipart/form-data');
the "FileUpload" takes care of the file and inserts it in the dbThe question is how does it do it? A file upload via mod_plsql/EPG is done via the PLSQL document table. It, mod_plsql/EPG, takes cares of the actual upload part - reading the Mime stream of the upload from the browser and inserting it into the document table.
Unfortunately, seems that the 11g documentation lacks details in this regard. Please consult the Oracle® HTTP Server mod_plsql User's Guide (10g).
<li>section 1.7.1 describes the format of the upload table you need to define
<li>section 1.7.4 shows a sample HTML form doing a HTTP post, and the post-process upload PL/SQL procedure that needs to be written to process the contents of the row just created for the uploaded file in the document table

Questions about OAS Portal Forms to upload files

Hello,
I have quetions, about uploading files, see I need to creat a form that will be used by other people to upload information that later will be presented as downloads in the portal...
so I created a form in my provider with a file (binary) field, and it mimes to my table in the DB, to the field "Archivo", then what I do is use a omniportlet and using HTML format I present like a link using the info in the field Archivo
and when I clic on it it takes me to this link
http://desarrollo06:7778/pls/portal/38173.PDF
but the file I uploaded does not appear
can aniyone help me to solve this?
thanks in advances for the suggestions and your time ^_^

The method you used to setup upload of file seems fine. I suppose you would have used a blob type to save the file in your db table.
basically, you can develop a report offering a link calling perhaps a procedure which would query from the table and download the file.
In that procedure, you would look for the file (vblob) and the mime_type from that table using a sql-query. then use them to setup the mime type for the http protocol, and download the file as follows.
owa_util.mime_header(mime_type);
owa_util.http_header_close;
wpg_docload.Download_File(vblob);
hope that helps!

Itunes Producer Problems Uploading - File not saving - file does not Exist.

Can someone please help me out, this problem is killing me. I've uploaded over 200 UPC Albums using Old G3 and Elderly ITunes Producer, but apple asked me to upgrade, so new machine to me Macmini maverics 10.9.? ITunes Producer 3.1.
So I click open ITunes producer 3.1. Click on make project from Audio
Files. Name and Save the project in Music-ITunes Producer-Playlists.
Plug in my external Flash drive and import the 40 Audio files for the
project. I am using an external flash drive as I can’t get ITunes Producer to
see my internal hard disk, I do not know if this is normal??
Go through the process of saving the project to Music – ITunes Producer –
Playlists – in this case 5060101121313
I then go through name all Tracks and make sure that all Data is correct.
Then when I finally go to either save the document or send it to you I get the
first Screen shot saying
"The Document "5060101121313" COULD NOT BE SAVED. The File does not exist".
As I say I have delivered 200 UPC’s to you with the old software and never
had any problems, I am in urgent need of making significant delivery to you so
would appreciate you help ASAP.

How to SCAN uploaded files for VIRUS in APEX

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
For more details on the Scan Engine Client API, please see Symantec Scan Engine Software Developers Guide.

public static void main(String[] args) {
clienttester g = new clienttester();
g.display();
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
* @param fileName
* @return
public static int scanfile(String fileName){
String avMode = "SCAN";
boolean scan = avMode.startsWith("SCAN");
String avServer = "xx";--avserver ip address
int avPort = 1344;
int the_return = 0;
if (scan) {
AVClient avc = new AVClient(avServer,avPort,avMode);
the_return = avc.scanfile(fileName);
if (the_return == -1) {
return (the_return);
} else

//my_return = the_return;

byte[] b1 = new byte[4];
b1[1] = 68;
my_return = scanfile("c:\\eicar.com");
System.out.println(my_return);
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.
package com.av;
import java.io.*;
public class my1 {
static int my_return = 0;

int the_return = 0;
if (scan) {
AVClient avc = new AVClient(avServer,avPort,avMode);
// File file = new File(fileName) ;
//byte[] fBytes = getBytesFromFile(file);
the_return = avc.scanfile(fileName, fileBytes);
if (the_return == -1) {
return (the_return);
} else
{return (the_return);}
my_return = the_return;
return (the_return);
// Returns the contents of the file in a byte array.
* @param file
* @return
* @throws IOException
public static byte[] getBytesFromFile(File file) throws IOException {
InputStream is = new FileInputStream(file);
// 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
// to ensure that file is not larger than Integer.MAX_VALUE.
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
if (offset < bytes.length) {
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.

Having main method helps you to run the file in JDEVELOPER or using JAVA.
DO not forget to load this class into the database.
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;

How to specify the directory in which we want to store the uploaded files

Hello !!
I am using apache commonfile upload for uploading my files.I followed the user guide and tried to run a program,but my problem is I am not able to understand as to how to mention the directory in which the uploaded file will be saved..My code is given below :
package r;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
import java.util.*;
import org.apache.commons.fileupload.*;
import org.apache.commons.fileupload.servlet.*;

import java.lang.Exception;
public class fileupload extends HttpServlet
     public void doGet(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException
               // Check that we have a file upload request
              boolean isMultipart = ServletFileUpload.isMultipartContent(request);
             System.out.println(isMultipart);
             if (ServletFileUpload.isMultipartContent(request))
             // Create a factory for disk-based file items
               FileItemFactory factory = new DiskFileItemFactory();
               // Create a new file upload handler
               ServletFileUpload upload = new ServletFileUpload(factory);
               // Parse the request
               try {
                         List items= upload.parseRequest(request);
                         Iterator iter = items.iterator();
                         while (iter.hasNext())
                               FileItem item = (FileItem) iter.next();
                             if (item.isFormField()) //NORMAL FORM FIELD
                             String name = item.getFieldName();
                              String value = item.getString();
                              System.out.println(value);
                              else
                             String fileName = item.getName();
                             System.out.println(fileName);
                                String contentType = item.getContentType();
                              File saveTo = new File("/info/upload_files/myFile.jpeg");
                         try
                                   item.write(saveTo);
                                   System.out.println("File written" );
                         catch(Exception e)
                                     System.out.println("File not written");
                               // InputStream fs= item.getInputStream();
                               fileName = FilenameUtils.getName(fileName);
                                System.out.println(fileName);
                    }//end of try
          catch (Exception e) { }
     public void doPost(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
             doGet(request,response);
The problem is that the control doesn't reach the try statement and I get " File not written" on the console because it enters catch everytime..Please tell me how the path to the directory should be given...Rest of the code is working fine

No, the problem is that when an Exception is thrown, you ignore it completely and throw away all the information associated with it. That leaves you to guess at what the problem is. So instead of answering your guess at a good question, I'm going to suggest that in all of your catch blocks you put this code:e.printStackTrace();Then you can look at the output in the log file and see what the problem is. Start from there.

Upload file to a particular folder in UCM

I want to upload file to a particular folder location in UCM.
When I am uploading it is going to the default location though i programmatically have set the folder path
I am using Adf application in Jdev 11.1.1.3
As i am new to UCM i do not have idea of whether to define the location at ucm level or in our program
Below is my code like this
public void checkInContent(TransferFile file){
UploadContentVORowImpl row=(UploadContentVORowImpl)this.getUploadContentVO1().getCurrentRow();
IdcClient client= UCMRepositoryOperations.getIdcClient();
DataBinder binder= client.createBinder();
binder.putLocal ("IdcService", "CHECKIN_UNIVERSAL");
binder.addFile("primaryFile", file);
String fileType=file.getContentType().substring(0,file.getContentType().indexOf("/"));
int contentId= new SequenceImpl("UCM_CONTENT_ID_SEQUENCE",getDBTransaction()).getSequenceNumber().intValue();
binder.putLocal("dDocID", contentId+"");
binder.putLocal("dDocName", file.getFileName());
binder.putLocal("dDocTitle", file.getFileName());
binder.putLocal("dDocType","DigitalMedia");
SimpleDateFormat sdf=new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
binder.putLocal("dInDate",sdf.format(row.getFromDate().dateValue()));
binder.putLocal("dOutDate",sdf.format(row.getToDate().dateValue()));
binder.putLocal("xScope",row.getScope());
if(row.getStateId()!=null){
binder.putLocal("xState", row.getStateId().toString());
if(row.getDistrictId()!=null){
binder.putLocal("xDistrict",row.getDistrictId().toString());
binder.putLocal("dLocation", "/Contribution Folders/sahaj/content/loginPageNews");
binder.putLocal("dAuthor", "Test");
binder.putLocal("dSecurityGroup", "public");
binder.putLocal("blDateFormat", "dd-MM-yyyy HH:mm:ss");
ServiceResponse resp=null;
String response=null;
try {
resp = client.sendRequest(UCMRepositoryOperations.getContext(), binder);
} catch (IdcClientException e) {
ucmAMLogger.severe(e);
try {
response=resp.getResponseAsString();
resp.close();
} catch (IOException e) {
ucmAMLogger.severe(response);
ucmAMLogger.info(response);
}

The xContributionFolder should be an ID, not a file path.
To determine the correct ID, this PL/SQL function may be useful :
function f_get_folder_id ( p_folder_path in VARCHAR2)
return NUMBER
is
v_parent_folder_id NUMBER := 429910249369000002 ; -- ID of 'Contribution Folders/Root' collection
v_folder_name VARCHAR2(255);
v_folder_path VARCHAR2(32000);
pos_next_separator NUMBER;
CURSOR c_get_folder_id ( p_parent_folder_id in number, p_folder_name in varchar2 )
is
SELECT dcollectionid
FROM collections
WHERE dcollectionname = p_folder_name
AND dparentcollectionid = p_parent_folder_id;
begin
v_folder_path := p_folder_path ;
-- strip first '/'
if ( substr(v_folder_path,1,1) = C_FOLDER_SEPARATOR ) then v_folder_path := substr(v_folder_path,2); end if;
pos_next_separator := instr(v_folder_path,C_FOLDER_SEPARATOR) ;
while ( pos_next_separator > 0 )
loop
v_folder_name := substr(v_folder_path,1, pos_next_separator - 1);
v_folder_path := substr(v_folder_path,pos_next_separator+ 1);
open c_get_folder_id ( p_parent_folder_id => v_parent_folder_id , p_folder_name => v_folder_name );
fetch c_get_folder_id into v_parent_folder_id;
close c_get_folder_id ;
pos_next_separator := instr(v_folder_path,C_FOLDER_SEPARATOR) ;
end loop;
v_folder_name := v_folder_path;
open c_get_folder_id ( p_parent_folder_id => v_parent_folder_id , p_folder_name => v_folder_name );
fetch c_get_folder_id into v_parent_folder_id;
close c_get_folder_id ;
dbms_output.put_line('Found :' ||v_folder_name||' id '||v_parent_folder_id);
return v_parent_folder_id;
end f_get_folder_id;

How to upload file to server physical directory

Dear Sir,
My Software Details:
Oracle9i Release 1
Oracle9iAS 1.0.2.2.2
Solaris 8
I have a web application developed using PL/SQL.
How do i upload a file from user to a server physical directory through Oracle9iAS without storing in database?
I can do this if file is uploaded to a 9ias upload table.
But i'm looking for solution on uploading file straight to the physical server directory.
Please advise.
Thanks.
Regards,
Jap Boon Churn

Hi Jap,
You won't be able to do this with modplsql if that is what you are asking. modplsql only uploads file into the database.
With that said, however, you can write your own CGI/Servlet/Perl program that does the uploading of files into the server physical directory. In your program, you will need to handle HTTP POST requests so that you can parse out the file contents and write it out onto the file system.
I am sure there is already some CGI/Servlet/Perl program out there that does this. If you search on Google, you should be able to find some and modify it to your needs. Hope that helps. Thanks.
Eric.

Upload file without asking user for the file

Hi,
I need to upload a file to server, but from my code, not using the file upload from page.
I have created a xml file and I need to upload to server when user open a web browser (without asking user to select a file).
How do I proceed??, or what kind of libraries do I must use?
thanks

Hi,
thanks for answer.
Let me try to explain again (I think its very simple).Simple, yes. But not very thorough.
I have developed a web application using JSF.So all the code is running on the server, right? There are no Applets, Applications or WebStart applications involved. Right?
My application has a splash screen where I show data. I have developed a bean to connect to my database (sql server), extract this data and create an xml (using DOM) file like:
<news>
<simplenews id="1"> Value </simplenews>
</news>And that bean runs ... where? Server again?
(important step) Once I have created the xml file in my bean I want to upload to the server to a place like /WEB-INF/news.
If the code is running on the server, then "uploading" is the wrong term, as there's nowhere to upload to, since you're already on the server.
This may sound like nit-picking, but you're sending us on a wrong trail with this phrase.
Once the file is on the server with another bean I read the xml fileWhy don't you simply store it in the application scope and let everyone access it from there? It doesn't sound as if the XML is huge.
As you can see I haven't a web page where to show an upload file componetYou also don't want to "upload" anything from the client, from the sound of it.
You simply want to transfer data between to server-side components, if I understood you correctly.

Uploading file to the servelet and write directly into database

i want client to upload file to the server (using servlet for that) and i just don't want to store it to the hard disk, but i want to write it
into the the ms sql database (that i m using).
TIA

Here is a good site for learning how to upload a file using a servlet:
http://www.servlets.com/cos/index.html
Once you get the file in the servlet you shouldn't have any problem storing it to a DB.

How to change name of uploaded file

I am using the a multi-part form and the pl/sql gateway to enable users to upload files to portal. The files automatically get stored in the wwdoc_document$ table. The key to the file is a column called "name" which consists of a sequence number and the file type e.g. 4747.gif.. I want to change this name to a different value.
When I change it using the standard sql Update statement, none of the pdk apis work on the record; they all return errors. I am able to change this value as long as I use a unique value, I just can't run any of the wwdoc apis against the row after that.
Does anyone know how to change this value for a given row???
