Download a text file to client machine

Hello everyone,
I'm trying to implement a report in EP6 SP2 version using Dynpage. I have it working perfectly, where in it displays the result in a Tree Format. But now the client wants a button, on clicking which it should download everything in a text file. I'm thinking of creating a text file and using FileOutputStream dumping the data into a text file. But I dont know how to open that text file or download it to the client machine ?
Can someone helpme with this ?
Thanks.

Another thing you can do is create a table that you can insert the results of the UTL_FILE export. This table will basically track all of your UTL_file exports. You would just have to have three columns in the table. An ID, Filename, Directory. The ID would be your Primary Key, Filename would be the name of the file, and the Directory, would be directory in which the file is in. Then you can build a portal dynamic page that selects the results with a hyperlink. Then everything will work dynamically. Let me know if you have any questions.
Thanks,
Martin

Creation of Text File on Client Machine

I am using Oracle 11i EBS and I have a requirement to create a text file on the client's machine. The name of the file is suppose to be on a particular format (DDMMYY.TXT). It is an urgent requirement from our client and we need to go live in 3 days. Kindly helP me out.

Creation of CSV file on client machine with data from forms

Hi,
My requirement is to generate a CSV file(or .XLS) on the client machine ie local drive with the details shown in a form.
Oracle version -
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 Production
TNS for Solaris: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production.
I have searched the web for last couple of days and got to know that TEXT_IO is to be used to generate files on client machine. However, when I tried TEXT_IO, it was not able to generate the file on client rather it was able to generate on database server. After further browsing on this, there was a link which said that we need to use CLIENT_TEXT_IO to generate file on client side. For this, i was required to subclass the webutil.pll which i did and corrected the code to use CLIENT_TEXT_IO. The form was unable to compile and was not able to find "webutil_core" package.
I am very confused with the disparity in the information available on the web as in what to use to generate a file on client side. If anyone has use it in the past, can he/she please detail what to use to get things sorted.
Thanks,
R

So, what is your FORMS version. This is more important than your database version.
My requirement is to generate a CSV file(or .XLS) on the client machine ie local drive with the details shown in a form. Depending on your Forms version, you would use TEXT_IO (if Forms 6i running in Client/Server mode) or WebUtil (if Forms 9i or higher).
I'm going to guess that you are at least using Oracle Forms 9i since you stated that your attempt at using TEXT_IO produced a file on the DB server.
There is more to using WebUtil than just attaching the WEBUTIL.PLL. If you had performed a simple search of the Forms Help System would have found numerous WebUtil topics to include: Introduction to WebUtil, Configuring WebUtil, Using WebUtil in Your Applications and the WebUtil User's Guide. If you have Oracle Forms release 10g or higher, WebUtil is included when you installed Forms, however, you do need to configure your installation to use WebUtil and you must download the Java COM Bridge (jacob.jar) from Source Forge. Take a look at the Configuring WebUtil Forms Help topic to find out which version of the Java COM Bridge you will need to download.
After you have successfully configured WebUtil, take a look at the Using WebUtil in Your Applications topic to find out how to implement WebUtil in a form.
Searching the Internet for answers is great, but don't forget the look at the Forms Help System because the majority of your questions can be answered there. :)
Lastly, configuration of WebUtil is primarily done on your Application Server (AS). However, if you plan to perform preliminary runtime testing by running your Form from the Forms Builder, then you will configure your local runtime to support WebUtil as well as configure your AS. The steps are exactly the same. A common mis-step is to skip a step during the configuration because you don't think the step applies. Take a look at the Forms Help Runtime Setup Checklist topic for a list of step you need to complete in order to enable WebUtil.
Hope this helps,

http://www.google.com/search?q=jdbc+blob
Blob processing varies between databases; see also examples for whatever database you are using, e.g.
http://www.google.com/search?q=jdbc+blob+oracle
If you are storing text data instead of binary data, replace "blob" by "clob" in the searches.

How to find out a file from client machine

hi all,
I want to read a file from client machine, like a outlook express file in which all the address are saved, using servlet. Initially i do not know the file path for that file, How i can read that file.
plz help me
thanx in advace
Manish

You have 2 possibilities. First, you might be able to mount the client's disk drive at the server; the servlet can then access that drive directly. Second, install a client program on the client machine and communicate with that program, and have it do the search (or whatever).
Outside of Java, there are remote-access programs - like PCAnyWhere.

Save file on client machine on the web.....

Hi,
I have a Form Application C/S 6i where I create a file using Get_File_Name, TEXT_IO.fopen .... etc. This application it's OK. The problem is when I load the application on AIS9i. The application don't load never. I must create and save a file on client machine when I use application on the web. What Can I do? Is This operation possible without radical change of the code source?
Thanks

Erik,
actually this project is under the leadership of the same author that created d2kwutil. It is too early to tell what exactly will be in this package and most likely we will release things step by step as they finish. However, you canuse this thread for a wishlist of functionality and I will pass it to the project lead. The implementation will be both POL/SQL and Java (as Java is the only way for us to access the client side in teh Web). The project target is sometime mid of next year. As said, the project hasn't really started yet so it is too early to speculate on what will make it in and when this will be delivered.

Error in Downloading the Text file on Application Server

Hi All,
          I am working on ECC6.0. I have written a program in whcih I am downloading the text file on

          want to download the data on application server in text file in non unicode format(Like ANSI or
          other non unicode format) which is supported by excel. When I am writing the code as

          Same in case if I add the code OPEN DATASET DN_FILE FOR OUTPUT IN LEGACY TEXT
          MODE CODE PAGE '8000' is also giving dump.
          So please let me know how can I download the file in non unicode format ?
          Any help would be greatly appricated.
Thanks & Regards

Open bat file on client machine using webutil

Hi all.
I'm on devsuite 10g.
I want to run a bat file on client machine using client_host function of webutil.
I have tried first to execute the bat file with mouse double-click in order to check if it is ok, and it works.
Now I want to execute this file from my form using webutil.
Here is my code:
--> with this code I select a file from client machine
Declare
     LC$Fichier Varchar2(1000):=null ;
     PC$Filtre Varchar2(2000) := '|All files|*.*|' ;
Begin
     LC$Fichier := WEBUTIL_FILE.FILE_OPEN_DIALOG
     null,
     PC$Filtre,
     'Seleziona un file da caricare'
If LC$Fichier is not null Then
:output.apri_file := LC$Fichier ;
End if ;
End ;
--> with this code I execute the file that I have opened
declare
     cmd varchar2(30000) := null;
BEGIN
     Cmd := 'cmd /c start "" "' || :output.apri_file || '"' ;
CLIENT_HOST(cmd);
END;
When I execute my form I have this error:
Exception in thread "main" java.lang.NoClassDefFoundError: ....folder of file opened.
Can anyone help me to solve this problem??
Thanks in advance,
Fabrizio

Hi Tony.

When you say the DOS window opens for few second, is your batch file being executed?? did you see the results??
The answer in NO for both of your questions.
If I try to drag and drop the file I have error.
How can I attach an image to this post, so that you can see the error??
Thanks,
FabrizioThis seems like a directory or OS level permission issue on the batch file, What is the error you got when you tried drag and drop the batch file in an DOS window???
I think you need to upload the image to a site and use the markup for the image, include the full URL of the uploaded file between ! (exclamation marks) something like ! http://../post.gif ! without the spaces.

Reading Large data files from client machine ( urgent)

Hi,
I want to know the best way for reading large data at about 75MB file from client machine and insert to the database.
Can anybody provide sample code for it.
Loading the file should be done at client machine and inserting into the database should be done at server side.
How should i load the file?
How should i transfer this file or data to server ?
How should i insert into the database ?
Thanks in advance.
regards
Kalyan

Like I said before you should be using your application server to serve files >from the server off the filesystem. The database should not store files this big >and should instead just have a reference to this file. I think u have not understood the problem corectly.
I will make it clear.
The requirement is as follows.
This is a j2ee based application.
Application server is oracle application server.
Database is oracle9i
it is thick client (swing based application)
User enters datasource like c:\turkey.data
This turkey.data file contains data
1@1@20050131@1@4306286000113@D00@32000002005511069941@@P@10@0@1@0@0@0@DK@70059420@4330654016574@1@51881100@51881100@@99@D@40235@0@0@1@430441800000000@@11@D@42389@20050201@28483@15@@@[email protected]@@20050208@20050307@0@@@@@@@@@0@@0@0@0@430443400000800@0@0@@0@@@29@0@@@EUR
like wise we may have more than 3 lacs rows in it.
We need to read this file and transfer this to the application server. Which are EJBS.
There we read this file each row in file is one row in the database for a table.
Like wise we need to insert 3 lacs records in the database.
We can use Jdbc to insert the data which is not a problem.
Only problem is how to transfer this data to server.
I can do it in one way. This is only a example
I can read all the data in StringBuffer and pass to server.
There again i get the data from StringBuffer and insert into database using jdbc.
This way if u do it. It is performance issue and takes long time to insert into the database.It even may give MemoryOutofBond exception.
just iam looking for the better way of doing this which may get good performace issue.
Hope u have understood the problem.
