Need Tutorial about file upload

Hi folks!
Have anybody a link or something else to a tutorial for uploading files with JSF?
And i mean with the "plain" JSF RI 1.2 from Sun. Google gives me a lot of Websites with Apache myFaces and myfaces extensions, but i use facelets.
So i have to bring all the the packages together and to mutch action for my little app.
Greetings, cpt.crispy

Using plain JSF RI 1.2 is not possible to do what you want.That's a pity!
So, you need to use an additional component library
like apache tomahawk.I know that. But what does the "additional component library" do?
Don't misunderstand me please. I want to learn how file uploads works in JSF and J2EE, not to learn some "magic" libraries.
For most Java problems you can get "additional libraries", but sometimes it's better you make it on your own to learn how it works.
Thanks for your reply, cpt.crispy

I Need Information Regarding File Upload?

Where can I get information regarding the File uploading packages in Portal. Is there a specification I can get a hold of. I know such a package exists, as it is used by portal itself. I just need to know where I can get hold of information as to what it is called and how to invoke it.

Suraj,
The APIs to do file upload are not public as of yet. We are looking into the feature right now. Currently, the only supported method of file upload is using the Web Interface.
You may find more information about this in the 9iAs Portal forum

i am giving you example for Change Vendor you practice for ur tcode
For our example, we will use the Change Vendor transaction (FK02) to add a street address to an already existing vendor.
Step #1
Use SystemStatus menu path to determine online program name (SAPMF02K), screen number (0110)
Step #2
Use F1 key and Technical Info pushbutton in each screen field to be filled to determine the field name.
Step #3
Determine how to proceed in the transaction
(save the record by clicking on the Save pushbutton or pressing the F11 key).
BDC Table Contents
After researching the transaction we can determine the contents of the BDC table.

Batch Input Methods
CALL TRANSACTION USING
STATEMENT
Call transaction - for data transferProcessing batch input data with CALL TRANSACTION USING is the faster of the two recommended data transfer methods. In this method, legacy data is processed inline in your data transfer program.
Syntax:
CALL TRANSACTION <tcode>
USING <bdc_tab>
MODE <mode>
UPDATE <update>
A Display all
E Display errors only
N No display
S Synchronous
A Asynchronous
L Local update
The process flow of CALL TRANSACTION
A program that uses CALL TRANSACTION USING to process legacy data should execute thefollowing steps:
Prepare a BDCDATA structure for the transaction that you wish to run.
Prepare a internal table to store error messages Tab_Mess like structure of BDCMSGCOLL.
With a CALL TRANSACTION USING statement, call the transaction and prepare the BDCDATA structure. For example:
CALL TRANSACTION MM01' USING BDCDATA MODE 'A' UPDATE 'S'. MESSAGES INTO TAB_MESS.
IF SY-SUBRC <> 0.

Overview of Batch Input Session
The first batch input method is to create a batch input session. It is the processing of this batch input session that updates the database, not the execution of the batch input program.

HI Masters , I need information for file upload program in web dynpro java

Hi masters,
i need some inforamtion and documentation on file upload program in web dynpro java

Hi surya,
You can follow this procedure to upload the file
i) Take One Context Attribute named as "D1" of Type "binary".
ii) Take one FileUpload UI Element in the Layout Tab.
iii) Bind FileUpload UI Element's data Property to the taken Context Attribute. Here it is "D1".
iv) Take one Button UI Element in the Layout Tab named "Upload" and in the Action of that Button write the following Code.
v) The following code Generates one Folder in the Server & inside that Folder given file is Uploaded.
File ff=new File("FolderXYZ"); // Creates One Folder with the given Name ( Here Folder name is "FolderXYZ")
ff.mkdir();
try
byte b[]=null;
IWDAttributeInfo objAttinfo=null;
IWDModifiableBinaryType binType=null;
File f=null;
FileOutputStream fos=null;
if(wdContext.currentContextElement().getD1()!=null)
b=wdContext.currentContextElement().getD1();
objAttinfo=wdContext.getNodeInfo().getAttribute(IPrivateAttachView.IContextElement.D1);
binType=(IWDModifiableBinaryType)objAttinfo.getModifiableSimpleType();
f=new File(ff.getName()+"
"+binType.getFileName());
fos=new FileOutputStream(f);
fos.write(b);
fos.flush();
fos.close();
objMessageManager.reportSuccess("File uploaded to server");
} catch (Exception e)
objMessageManager.reportException("Unable to upload file to server, error is:"+e,false);
return;
The Uploaded file is stored in the folder & that folder is stored in the Server's following Path.
<Your Server>\c$\usr\sap\J2E\JC00\j2ee\cluster\server0
You can access your Uploaded file from the following Path
<Your Server>\c$\usr\sap\J2E\JC00\j2ee\cluster\server0\FolderXYZ

Question about File upload functionality in Weblogic

Hi,
    We're currently trying to deploy a web application on the weblogic 12c server (via war file). And the app needs to upload a text file onto the a temperary directory within weblogic server. And on the web page side, we use JQuery File upload plugin.
    My question is, on the file receiver side, does weblogic provide any tools to receive the uploaded file and store it?
Thanks very much in advance.

Hi,
Before setting the string or xstring to server->response->set_cdata (string) or server->response->set_data (xstring) try this:
CONCATENATE 'attachment;filename=' lv_filename '.xml' INTO lv_string.
* Setting the filename by default
server->response->set_header_field( name = 'Content-Disposition'
                                      value = lv_string ).
Hope this helps.

Need help for file upload - reposted for Steve Muench

Hi Steve,
I have been involved developing a web application that requires a file upload operation. I have studied your example on Upload Text File and Image Example in the Not Yet Documented ADF Sample Applications section. I got the file upload part worked but could not get the original file name to populate the name field..i.e. if I upload myFile.txt to the database, the name field will be myFile.txt (not the name enter by user). Is there a way to capture the filename info? or is it possible to do so within ADF framework? I am using ADF/Struts/JSP with ORDDoc data type. Thanks very much.

Hello Nani,
You need to change any settings in 'FILE' transaction. This transaction is used to set up Logical file paths. ( In general it will be set already for your system).
You can use the following code.
DATA: LC_LOGICAL_FILENAME_EXPSRC LIKE RCGIEDIAL-IEFILE
                                                VALUE 'EHS_IMP_SOURCES'.
DATA:      L_EMERGENCY_FLAG            TYPE C.
DATA:      L_FILE_FORMAT               LIKE FILENAME-FILEFORMAT.

Question about file uploads

is having a file upload function on a web page a hard thing to do?
i need to do this, but i do not know where to start...
if anyone can help me out/shed some light on this for me that would be greatly appreciated!~!!!
THANKS!

No it is not particularly difficult; I let the user select a file on the client filesystem then upload to the server.
The form ENCTYPE must be multipart/form-data:
<FORM NAME="frmUpload" ENCTYPE="multipart/form-data" METHOD="POST" ACTION=...>
Use:
<INPUT TYPE="file" NAME="srcFile" SIZE="15" MAXLENGTH="40">
In my servlet:
verify:
String contentType = request.getHeader("Content-Type");
if (contentType.indexOf("multipart/form-data") < 0) {
...handle error...
String boundary = contentType.substring(contentType.indexOf("boundary=") + 9, contentType.length());
private boolean TransferFile(ServletInputStream is, String srcFile,
String destDir,String caseNo, String boundary, String errorPage,
HttpServletRequest request, HttpServletResponse response) throws ServletException
File pathName = new File(...);
// If the target directory does not already exist then create it.
if (!pathName.exists()) {
pathName.mkdir();
if (!pathName.exists()) { // did mkdir work?
... do lots more checking ...
boolean xferOK = false;
try {
FileOutputStream fout = new FileOutputStream(...);
byte[] nextBytes = null;
byte[] currBytes = null;
while ((nextBytes = ReadLine(is)) != null) {
if (currBytes != null) {
String snippet = "";
if (nextBytes.length - 10 <= boundary.length())
snippet = new String(nextBytes);
if (snippet.indexOf(boundary) < 0)
fout.write(currBytes, 0, currBytes.length);
else
fout.write(currBytes, 0, currBytes.length - 2);
currBytes = nextBytes;
fout.close();
xferOK = true;
catch (IOException ioe) {
return xferOK;
} // TransferFile()
Hope this helps

NEED HELP about file handling and searching

Hi guys !!!!!!!!!!!!!!
A) I need a help from u i wrote this programme to read from the file and assign the lines for the string array.
import java.io.*;
public class ReadFile{
public static void main(String[] args){
int i;
BufferedReader file;
String line() = null;
String fileName = "xx.txt";
 try {
 file = new BufferedReader(new FileReader(fileName));
for(i=1;i<=10;i++){
line(i)= file.readLine();
System.out.println(line(i));
file.close();
 } catch (FileNotFoundException e) {
 System.out.println("File: " + fileName + " not found.");
 } catch(IOException e) {
 System.out.println("Error reading data from file: " + fileName);
the thing is it is compiling but when interpritting it gives the error
Exception in thread "main" java.lang.NullPointerException in line(i)= file.readLine();
plese help me on this and
B) i want to know how to search the string array to find 4 letter words.
i'm taking the each element which is line(i) one at a time and search it.
Plese help me on these issues !!!!!!!!!!!!!!!!!!!!!

You try to create an array with line(i) (as far as i see) but you dont need to keep each line in memory. As far as i understand you just need to process lines sequentially.. (Null pointer exception is thrown because you did not create your array properly!)
Look at this code:
http://www.java-tips.org/java-se-tips/java.io/reading-text-from-a-file.html
You just need to define process method in that code. (and of course try to understand). So as far as i see, you will check for 4-letter words inside process method!
For detecting 4-character word, you need to extract the words in the line using StringTokenizer:
http://www.java-tips.org/java-se-tips/java.util/how-to-use-stringtokenizer.html
Then you can just just use length() method of String class:
http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html
And if you need more advanced logic for processing the lines(currently seems to be the length of strings), you may try regular expressions:

About file upload

Hi all;
I have problem which is i down load the image in my table when i upload it it give me error like forbidden 403.
Please help me
thanks.

thanks Denes to get interested
I can upload all the doc i want with less than a total cumulated size of 100Mo. But
I think that i've found. After have try to change different values in the SGA and PGA parameters without result, i'm almost sure my problem comes from the size of my temporary tablespace. I'm not Oracle specialist and i didn't expect this tablespace was in use during this operation. I'll make some tests but it should be work if i increase this buffer. But i don't understand, for downloading blob with 4Go size, do you have to fix temp tablespace size to 4Go?
For those who could be interested, there is my code (don't be afraid, there is a lot of comments):

I add just this function quite useful in my case, which enables to circulate through a folder arborescence :
* Enable to progress through a complexe directory and each one of its dependences
* All the documents found into this directory are uploaded into the database
* Their details are loaded too with keeping link between the doc and its details
public void parseFilesNUpLoad(File rootFolder,
Log myLog) throws Exception {
myLog.lineWriter("the root folder is : ",
rootFolder.getAbsolutePath());
if (rootFolder.isDirectory()) {
File[] list = rootFolder.listFiles();
if (list != null) {
for (int i = 0; i < list.length; i++) {
parseFilesNUpLoad(list[i], myLog);
if (list[i].isFile()) {
DocBlobData blobTest =
new DocBlobData(list[i].getAbsolutePath(), myLog,
idEntryBlob);
myLog.lineWriter(" ");
DocDetailData detailTest =
new DocDetailData(list[i].getAbsolutePath(), myLog,
idEntryBlob, idEntryDetails);
myLog.lineWriter(" ");
idEntryBlob = idEntryBlob + 1;
idEntryDetails = idEntryDetails + 1;
} else {
myLog.lineWriter("parseFilesNUpLoad",
"!!! CRITICAL ERROR with the root folder at : " +

Need help w/ file uploading!

hi! i'm writing a JSP where the client has the possibility to upload image-files
to the server.. anyone have a good way to it? and if so how?
if you are referring me to some java-classes i would like to get proper
information on how to append them in the best way possible...
i've heard about the MaybeUpload package by Weft but there's one thing i
don't understand... in the form you use the <input file=""> tag, but how do i
obtain the file? if use request.getParameter() i would get the path, wouldn't i??
hope you can help me out!

You are probably timing out with your web server. Check the server logs to see if there are any errors there..

A lady came up to me on the street, pointed at my suede jacket and said "Do you know a cow was murdered to make that jacket?"
"I didn't know there were any witnesses", I replied " Now I'll have to kill you too"

Need advice about files back up

Could you please tell me how I can easily (I am not technically competent) backup the following:
- Microsoft security updates
- Norton security updates
- other downloaded software program updates
- emails
- Internet "Favourites" list
- desktop display settings
- any other important files you suggest
Your help would be gratefully appreciated.

It sounds like you need a disk cloning program similar to the software used by Toshiba for their product recovery discs.
There are several commercial products like Norton Ghost for example but there are also free ones like Terabyte Unlimited CopyWipe:
http://www.terabyteunlimited.com/copywipe.html
Unfortunately I have used neither program so I really can't comment on how good they work.
