Saving Files in Client machine

Hi,
Iam generating a servlet application to save reports,
For this i created a browse button where user can specify the system path.
when the user clicks save the reports should be saved in specified path of client machine..
some how am not able to save in client machine(Windows).Its getting saved in server ..
Please suggest any solution,
Thanks

You're using java.io to write to local disk? This is indeed not going to work :)
Provide it as file download. Set the content disposition to attachment and write the binary file contents to the outputstream of the response. You may find this example useful: [http://balusc.blogspot.com/2007/07/fileservlet.html].

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.

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,

You can use cos.jar provided by O'Reilly from http://www.servlets.com/cos/. Take a look at com.oreilly.servlet.multipart.* classes.
Package is provided with source, classes, documentation and, of course, ready-to-use jar file.
It is really usefull and - ready!

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.

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.

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.
I have tried to run my bat file with double-click and everything is OK.
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.

How to write files on Client Machine using JSP

Hi,
I am new to JSP. Please tell me how do i write files on Client machine thru a Browser.
Please let me know at the Earliest.
Thanks.
Mehul Dave

1) Well I find it rather convenient to deploy a web app as just one file rather than a bunch of files. For deployment it's much better. However I prefer using expanded files when developping (to use auto reload in Tomcat for example)
2) It is a bad idea to upload files inside your webapp's context (ie: in it's deployment directory) because one day an uninformed system administrator might come and redeploy the web app and therefore delete all your uploaded files (believe me, I've already experienced this!)
What i do usually is upload it in a completely different directory, something like /uploaded_files. Your uploaded files are therefore completely independant from your webapp
However it is a bit trickyer to get those files back. Let's take the example of image uploads. You have 2 ways of proceeding:
- the easiest : configure your web server (apache etc...) to redirect a certain url to your external directory. For example the /upload url will point to a /uploaded_files directory. This is easier to do and the fastest way to serve images but not always the best solution: you are dependant on the web server's configuration and you can't control the visibility on your files (no security constraints, anyone can see your uploaded files if they know the url).
- you can also write a servlet which will load the file as an array of bytes and send it back in the response.
You can call it this way :
<img src="/serlvets/showmyimage?path=uploaded.gif">
in this way you can control your uploaded files better: you may want to define security constraints on the visibity or not of uploaded files depending on the user which has logged on the site.

Creating excel file on client machine using oracle pl/sql code

Hi All,
I have a situation where in i need to create an excel output file in my client machine, but using UTL_FILE i understood that i need to create the directory on server and i need to read and write on server itself.
Is there any other way where we can create a excel file other than oracle server, bcos this is used only once and there is no scheduler to execute on server.
Please do the needful.
Thanks,

The server should create the data set required by the client - do all the (intense) server processing that servers do well. This data set is then send to the client. The client is responsible for rendering that data set.. or saving it to the client machine storage if needed.
Within PL/SQL that is quite easy to do using the most common/standard client-server in use today - web based client-server.
The client is a web browser. It makes a call to the web server, that is serviced by a PL/SQL database procedure - a so-called web enabled procedure. It processes the request from the web browser, and returns a dynamic response. This response can range from HTML and XML, to video and image streams - and also CSV (Character Separated Values) data.
By default, most web browsers will use the local client spreadsheet application (like MS Excel) to open the CSV response received. Many web browsers will also provide an alternate option of saving that response as a CSV file (that can then be opened later using MS Excel).
Straight forward and basic client-server - and easily done using PL/SQL. Even easier done using (freeware) Oracle APEX (Application Express). APEX is a PL/SQL software suite that provides a web development system (only web browser required for development) and a run-time system to run the web application you have created.

10g - disconnected analytics, encrytion on csv file in client machine

hi, experts,
I found that the disconnected analytics client firstly download the data from server and SAVED AS CSV FILES.
but everyone can view the content in csv files.
IT IS UNSAFE.

Is there is any process or utility on which i can build on my previous approach to get my csv file on my client

The answer to this question is the question.. What is client-server?*
PL/SQL, SQL, Oracle, database ... all these equal server.
SQL*Plus, TOAD, web browsers... all these equal client.
Who handles the presentation of data on the client? Who has access to the client platform's keyboard, mouse, screen printer, disk drives, etc? The client.
So how can a server process or component then hack across the client-server architecture and into a client component and write data (e.g. CSV files) there?
This is a fundamental concept that needs to be clearly understood when dealing with all aspects of client-server.
What also needs to be understood that client-server is a software architecture. This means that client-server can run on a single machine. Client can run on a PC. Server can run on a big Unix machine. Or server can run on the PC and the client can run on the big Unix machine.
Which means that you can have PL/SQL code (on the server platform) acting as a client.. and use server software on your client platform to service that PL/SQL session.
For example. PL/SQL creates a CSV "+file+" as a CLOB. PL/SQL uses a FTP package and opens a client FTP session to a FTP server on your client PC. Now your PC is the FTP server and PL/SQL the FTP client. The client then proceeds to FTP the CLOB as a CSV file.
