Upload binary files with Developer Forms

Hi all,
I'm newbie with Forms and I don't know if this question is already answered.
I'm deploying an application involved with blob columns (binary files: pdf, doc, gif, etc) I want to let users to choose files from his PCs (typical "Browse files" button) but I don´t know if this is possible and if yes, how to implement it.
Anybody can help me?
My email is [email protected]
Thanks in advance!

If you want to upload direct into the database from the client then No you will need a 9i database or above.
If you want to upload a file from the browser client to the middle tier (Application server) then that will be OK no matter what DB version you are using. Bug of course you'll then need to do the last bit yourself if you want the document / image put into the database.

Upload binary file with DSEEntry

Hi ,
I have created a Class for a upload pictures to the IDM Database .
Now I have the problem with the upload.... and the mssql datatype.
At the moment the type is binary(max)
is there any option to add a byte[] to DSEntry.put ?
It seems that DSEntry always try a cast to string , and when put a byte[] I receive an exception.
Regards

Usually binary values are B64 or HEX encoded during processing in IdM. I take it you're trying to write it to a column of datatype binary, not an actual IdM attribute. Perhaps you should use varbinary(max) if you want to exceed 8000 bytes. But, the internal datatypes and the JDBC datatypes are not the same, so for SQL Server you need to use LONGVARBINARY.
see this MicroSoft reference: Using Advanced Data Types
Anyway, here's a working example. The $includebin function is documented in the helpfile but its usage is pretty self explaining in my example here:
My table looks like this:

Upload multiple files WITH correct pairs of form fields into Database

In my form page, I would like to allow 3 files upload and 3 corresponding text fields, so that the filename and text description can be saved in database table in correct pair. Like this:
INSERT INTO table1 (filename,desc) VALUES('photo1.jpg','happy day');
INSERT INTO table1 (filename,desc) VALUES('photo2.jpg','fire camp');
INSERT INTO table1 (filename,desc) VALUES('photo3.jpg','christmas night');
However, using the commons fileupload, http://commons.apache.org/fileupload/, I don't know how to reconstruct my codes so that I can acheieve this result.
if(item.isFormField()){
}else{
}I seems to be restricted from this structure.

How to upload binary file in database?

Using servlets..how to upload binary file into database...
How to get the data of file in servlet...
Please reply...i'm unable to find exact code...that i want..

You need to do two separate parts: accept the file from a HTTP multi-part POST and then stream it into a BLOB on the database. To do the former, download Jakarta Commons FileUpload. There is extensive documentation on how to write a simple handler for the upload. You then need to send the data to a BLOB. The specifics vary from database to database but generally you will insert or update a row with an empty blob, get a reference to the blob, pipe the data and then commit.
If you do a quick forum search, this question has been asked (and answered) dozens of times. Some of the replies may even have code for you. Best of luck.

I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?

I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

Display blob file with oracle forms

I need to display an image file with oracle forms.
can any body tell me how to do this ?
Thanks

How to do this is dependent on which version of Oracle Forms you are using. Please let us know what version (eg; 10.1.3.x.x not 10g) of Oracle Forms you are using and how your application is deployed (Client/Server or web). If web, what is your Java version?

How to upload a binary file with Firefox 7

Don't know if this is the right forum to ask this - if not, please point me in the right direction.
I am an embedded developer using Firefox as the user interface to an embedded web server. In the past I've been using file.getAsBinary() to read the local file which is then uploaded with an XMLHttpRequest. Firefox 7 removed the getAsBinary method. Looking through the documentation I came across FileReader and have been trying to use that but with no luck. When I use the readAsBinaryString method, the binary has many bytes which are in error. I have also tried the readAsDataURL but this gives me base64 encoding. Attempts to decode it so far have been unsuccessful. What's the best way to get a local file and upload it to a remote server?
Thanks,
Dave

Well, actually, i have no perfect solution.
I just used a temporary internal table in which all fields are characters. Then, I used FM GUI_UPLOAD to upload text file including header into this table as usual.
You can see that it was done successfully. Next, use a loop to transfer this temporary table to the main table. SAP will automatically convert data into values that are compatible with data type in the main table, so don't worry about different types :D.
In order to make this work more simple, field names of temporary table should be named exactly as same as those in the main one. So, u just use:
loop at itab_tmp.
move-corresponding itab_tmp to itab_main.
append itab_main.
clear itab_main.
endloop.
note: both tables have their own header line, so don't need use a working area here.
Anyone has any better solution?

Gui_upload for uploading binary file

Hello All,
I am trying to upload '.jpg' files using gui_upload function.
But something goes wrong and it dumps.
I am new to ABAP.
following is the code i used.
DATA: xline TYPE xstring.
DATA : t_file LIKE TABLE OF xline WITH HEADER LINE.
CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filetype = 'BIN'
      filename = 'C:\Documents and Settings\I046674\Desktop\RawTest\images\Image_1000.jpg'
    TABLES
      data_tab = t_file.
It dumps in the 'GUI_UPLOAD' function itself.
Saying follownig,
==========================================
Error analysis
    The error occurred at a statement in the form
      ASSIGN f TO <fs> TYPE t
    One of these two cases occurred:
    1) Field f is a string, a data reference, an object reference, an
       internal table or a structure that contains such a field. With the
       TYPE addition, this is not possible.
    2) Field f is of type x and field symbol <fs> has a character-type type.
       When executing the statement, the length of f is not a multiple of
       the length (in bytes) of a Unicode character.
===============================================
Can someone help me on this?
Thanks & Regards,

Binary file with File adapter

Hi gurus,
I am getting binary file as base64binary (not a text/xml file) in a request XML tag. I need to write this file to a file directory with the file adapter after retrieving it from the request message by a message/java mapping and use another field in XML as the file name.
I followed the blog `how to send binary data through PI` but in that case, the request message is also the same. Mine requires a mapping to be executed and in this case I cannot use dummy names for message types/interfaces as Enterprise Repository development is required.
How can I achieve this?
Thanks
Gokhan

Just solved the problem actually
As I was trying to write a binary file directly with the receiver file adapter, I wasn't sure how to define a data type / message type for it. I developed a java mapping that decodes the base64 to binary data and writes it to the output stream, and used a dummy message type / data type for the service interface as the target in Operation Mapping
And it worked!

Gökhan

Uploading a File with AppleScript via JavaScript

Hi everybody,
being new to AppleScripting and JavaScripting I'm faced with the following problem:
Is it possible to make AppleScript to input the path for a file to be uploaded via JavaScript? If yes, what should be the correct Path Format and how to wrap it up the JavaScript action into AppleScript? I've tried a few comands but to no success.
On the webpage in question, there's a "Choose" button, that is defined as follows:
<input type="file" class="gwt-FileUpload" name="swfFile">
I've been trying to use the following syntax:
do JavaScript "document.getElementsByName('swfFile')[0].value('Macintosh HD:Users:myaccount:Desktop:Scrapbook:!动画.swf')" in document 1
as well as this one, where the Path is definitelly understood by shellscript:
do JavaScript "document.getElementsByName('swfFile')[0].value('/Users/myaccount/Desktop/Scrap book/!动画.swf')" in document 1
The name of the file is (and must remain) in chinese, but for testing purposes I have also tried files with english names, without success.
Currently I'm using a solution with JavaScript comand:
do JavaScript "document.getElementsByName('swfFile')[0].click()" in document 1
to click the finder window to browse for the file, and manipulating keystrokes by using System Events to find the right file, but it's not infallible with a number of files and it's hardly an ellegant sollution.
Any idea what I'm doing wrong?
Cheers!

@twtwtw
the do JavaScript "document.forms[0].submit()" command didn't work, so I kept the original way of submitting by clicking the button. The submitting part works, but not the input file part.
That's the code I used
    tell application "Safari"
        do JavaScript "document.getElementById('gwt-uid-13').value='on'" in document 1
        do JavaScript "document.forms[0].elements['swfFile'].value=" & "'" & SWFFilePath & "'" in document 1
        do JavaScript "document.getElementsByClassName('gwt-SubmitButton')[0].click()" in document 1
        delay 1
    end tell
with SWFFilePath set as the POSIX path as well as the default file format
Macintosh HD:Users:myaccount:Desktop:Scrapbook:!动画.swf'
but it did not work.
If you've got the time, feel free to upload an .swf. The service is free and the server delats uploaded files after 15 min. (if you don't have any, you may try an empty .txt file instead - it won't get converted, but the point is just to get it into the input box).
In the meantime, I'll have a look at adayzdone's suggestion. It's not perfect (the downside being that it requires the window to be active, so I can't run the script in the background or with my screensaver & password on), but it's still more reliable than my sollution with navigating arrowkeyes.

How to delete one existing file before uploading a file with same name?

Hello everybody.
I am uploading a file to Tomcat server. But, the problem is:
i want to delete an existing file in the server, if i upload a fresh file with same name. In other words, "First check for the file with the same name in the server. If it exists, then delete existing file in the server and upload fresh one". If such file doesnot exist, then upload the file to server.
I have given deleteonExit()
but, for the first time when user is uploading, i want to check for the file with same name in the server.

Thank you MartinHilpert,
I have one more doubt,
I am uploading the file to one folder called "uploaded". Before uploading a fresh file, i want to delete all existing files in that folder. IS that possible ?? If yes, can you please tell me how to do that ??

Getting Java Beans working with Developer Forms 6i

Hello everyone,
I have been trying to get Java Beans to work with the Developer Forms 6i. I keep getting diffrent errors depending on the bean I play with. I will detail the problems and the computer setup. I am sure this problem is a configuration one, I just dont seem to have enough experiance to determine the issue or the configuration problem.
Here are the problems I am encountering:
Problems 1:
--JDeveloper 10g
I cant see the VBean class. When I add this code, the VBean decleration comes up with an error.
import oracle.forms.ui.VBean;
public class MyNewClass extends VBean
public Class1()
This code shows the IMPORT statement with a wavy blue line under it and the word VBean after the extends also has on. I understand that this means that the JDeveloper cant find the class, I just cant seem to find the correct environment variable to set to point to this.
Second Problem:
--Forms 6i
I open forms, and create a new form. I then add a datablock and a canvas. I open the canvas and drop the BeanArea component on the canvas. I enter the fully pathed/qualified Bean in the Implementation Class and get one of three errors. Either a FRM-13008, a FRM-99999 with a 13009 or a 13010 error. I suspect that the 13008 error is because the bean I created does not have the correct decleration types or IView interface calls. My problem is that when I load any of the Oracle provided beans I get the 13009 or 13010 errors. I have looked here and in Metalinks for some kind of solution that I haven't already tryed, but to no avail.
Any advice on either of these problems would be appreciated. Please keep in mind that we cant upgrade to version 9 or 10 yet (silly aif force and their regulations), so those type of solutions arn't usable to me.
Here is the configuration information that I know about. If there is more information that can be provided or I need to provide more information, please let me know and I will get what I can.
Thanks,

Ok, I added the f60all.jar to the project. This allowed me to create the file using the VBean. I created the JAR file and copied it to the forms60/java directory. I also copied the new .class files to the forms60/java/mil/af/rs/leads direcory.
I then edited my formsweb.cfg file and had to add the jinit_archive tag. I set it = f60all.jar, P3load.jar. I also added my P3load.jar file to the default archive tag.
When I open up Forms, drop the bean area component on the canvas, and set the Implementation Class, I still get an error (13008), and when I run the form in web, and click the button to invoke the bean I get no response from the bean.
here is the code to invoke the bean. in_filename is a text component on the canvas and contained in the CTRL block. The bean area is named BEAN (because the demo was that way).
:in_filename := get_custom_property('BEAN',1,'getFileName');
synchronize;
Not sure where to go from here, but thanks for the help so far.
