How to save file from server to client machine
Hi,
By using POI library i'm writing values to the existing excel sheet which is available in server. After i written values to the excel, i want to save the same file to the client machine.
How to achieve this.
I googled about this, but still i didn't get any clear idea.
Thanks in advance,
SANSameera,
No, i can't understand what is the meaning of the following code:
public void doDownload(FacesContext facesContext, OutputStream outputStream) {
// write the neccessary code to get the download data from the Model
String data = getDownloadData();
// save to the output stream
try {
OutputStreamWriter writer = new OutputStreamWriter(outputStream,"UTF-8");
writer.write(data);
writer.close();
outputStream.close();
} catch (IOException e) {
// handle I/O exceptions
can you please explain this code little more.

Vendor application only call the URL with parameter
to get the File in secured manner. OK.
the Vendor
application may be in java or not..NET ?
so in that case
also do.so what ? is your problem solved or not ?
you may need to make webservices. -
How can i transfer more than one file from server to client
Hi,
our requirement is transfer more than one files from server to client using the
webutil_file_transfer.as_to_client_with_progress.One file transfer is already working in our system.If anybody know the solution please inform
regards
matjust an idea ...
for this purpose let us put aside security concerns and other potential problems....
-- Get the content of a server directory with Filter and create zip file
1) create a class that implements java.io.FilenameFilter ...
2) define accept() method ...
3) call File.list() with the filter as a parameter. The returned array of strings will have all the names that passed through the accept() filter
4) use java.util.Zip to create ZIP file on the server side
-- I think it is better to create this functionality as a separate Java class, put it in required folder and after it
-- use Forms->Program->"Import Java class" to create pl/sql wrappers, than to create wrappers for all classes and code in pl/sql
5) use webutil to transfer file on the client
6) use Java on client side to unzip transferred file
if you think this is not too complicated, you should try ...

How to delete the files from server through OAF page
Hi All,
I have a requirement in which i am creating files on server through my CO code.
Now once the page is rendered, i want to delete the files from the server.
Just wondering how can we achieve this.
Kindly advice!
Thanks,
SachinHi Sachin
all the methods in the processRequest() are called during loading of the page.
all the methods in the processFormRequest() are called during any action events on the page.
So Use the method in processFormRequest() : write a method in
that on which action you want to delete the file.

Move files from server to client
I have create txt file in server directory using UTL_FILE package,
and I put in the directory in server.
Server platform is linux. and client platform in Windows.
What I want to ask is there any possibilities to copy that file from server to client using pl/sql ? could all of you "The Gurus" give me a script example ?
Thanks a lot.
regards,
indra> What I want to ask is there any possibilities to copy that file from server
to client using pl/sql
No. Not really.
Think about it.. the file is on the server. PL/SQL code executes inside the Oracle server session that is servicing the client.
Just how is PL/SQL (on the server) suppose to reach out and push that file to a client's file system and directory?
PL/SQL cannot do this. You need something on the client that will accept the file. You need something in-between the client and PL/SQL that will handle the transfer of the file. This something can be ftp, scp, tftp, NetBIOS etc.
Anyway you look at this, it does not make sense. You are turning the server into the client that needs to push the file. You are turning the client into a server that needs to accept the file.
Why? This is contrary to the basic client-server RDBMS architecture. You are adding more complexities and more moving parts to the architecture by forcing a swap of client and server roles. The are now a far greater likelihood of errors and bugs and failures.
It does not make sense to do it this way.
What is the business requirement you are trying to satisfy? Instead of us trying to help you to hack a flawed solution, let us rather assist you in determining the correct and proper solution. -
How to monitor all SAP Server through solution Manager?
Dear Friends,
How to monitor all SAP Server through solution Manager?
Is it possible if yes then how? Please forward configuration and transaction also.
Please help me as early as possible..
Thanks,

SachinHi sachin,
You can monitor your sattilite systems through solution manager.
If you want to monitor systems in solution manager means you need to configure those systems in solution manager.
Before including the systems in solution manager we need to create a solution using tcode <b>DSWP</b>.
After that you can include the systems using tcode <b>SMSY</b>.
For configuring the systems we have lot of phases its very difficult to explain here.
Try to login to<b> service.sap.com</b> and <b>help.sap.com</b> find the helpfull guides.

How to get file from server while click on link
Hi,
i created on link and i gave one server path to select file from server but while clickinng on link it no displaying any thing.
following is the Destination url that i gave for the item.
/u08/app/appvis/xxex/inst/xxex_apps/xxrbe/logs/appl/conc/log/
please tell me how to get file from server while click on link.Ok I got your requirement now.
If you are getting file names from view attribute then you should not be adding destination URI property for the link.
Instead you can use OADataBoundValueViewObject API.
Try below code in your controller processRequest method:
I am assuming that you are using classic table.
Also in below example it considers OAMessageStyleText and you can replace it with link item if you want.
OATableBean tableBean =
(OATableBean)webBean.findChildRecursive("<table item id>");
OAMessageStyledTextBean m= (OAMessageStyledTextBean)tableBean.findChildRecursive("<message styled text in table item id>");
OADataBoundValueViewObject tip1 = new OADataBoundValueViewObject(m, "/u08/app/appvis/xxex/inst/xxex_apps/xxrbe/logs/appl/conc/log/"+"<vo attr name which stores file name for each row>");
m.setAttributeValue(oracle.cabo.ui.UIConstants.DESTINATION_ATTR, tip1);

How to read files on server from a java program?
Hello,
I am fairly new to JSP programming. I have an issue with reading files. I am trying to call method of a normal java file from a jsp program. The method I am trying to call does some IO operation on Files. I have the files in the same directory as my class files on server that is in WEB-INF/classes folder. In my java program, I am giving just the file name to open because the files and the classes are in the same directory. But this is not working.
What exactly should I do to read a file from a java program, that is running on the server?
Any help is appreciated.
Thanks,
KrishnaString realFilePath = application.getRealPath("/WEB-INF/myFile.txt");
File fileToOpen = new File(realFilePath);
out.println(fileToOpen.getAbsolutePath() + ": exists? " + fileToOpen.exists());in this case "application" is a reference to the ServletContext.
It is an implicit variable in a JSP. In a servlet:
ServletContext application = getServletConfig().getServletContext(); -
How to send a user defined parameter to a web form?
Hi,
I4m looking for a solution how to send a user defined parameter to a web form when I start the form from a html-page.
I think that it should work to add the parameter to the URL.
Example: I added myparam=myvalue at the end oft the URL
http://my.server.com:7777/f60cgi?form=myform.fmx&userid=scott/tiger@mydb&otherparams=useSDI=NO&lookAndFeel=generic&colorScheme=teal&myparam=myvalue
How can I fetch the parameter myparam in forms?You have the user the otherParams parameter, which you can specify in the formsweb.cfg file, or override on the url. e.g. http://myhost/servlet/f690servlet?config=myApp&otherParams=myParam=myValue
In the Forms Builder, in the Navigator window, there is a node called Parameters. Create one in there, and then you can refer to it like a block variable. e.g. if :myparam = 'myvalue' then...
At runtime, Forms will match up any parameters on the command with parameters defined in your form, and populate them for you. You don't have to do anything.

How to copy file from server to another machine in network through JSP
Hello!
any body can solve my problem.
i m working in JSP. i want to copy a file from server on which JSP engine is running to another computer in the same network.
i used Java File Object to copy file from one machine to another in network. and its working fine on network. but the problem is when i used the same code in web page there is exception which is Access is Denied. what i should do now.
i m writing the code i m using in my JSP page
String fileToCopy = "C:/oracle/Apache/Apache/htdocs/FAO/FAO_MiddleFrame.jsp";
String destinationDir = "\\\\af09\\c";
File source = new File(fileToCopy);
String fileName1 = source.getName();
if ((!destinationDir.endsWith("\\")) && (!destinationDir.endsWith("/"))) {
destinationDir = destinationDir + "\\";
File destination = new File(destinationDir + fileName1);
if (!destination.exists()) {
if (!destination.createNewFile()) {
//throw new IOException("Unable to create file. May be you don't have permissions.");
byte[] buffer = new byte[1024];
FileInputStream in = new FileInputStream(source);
FileOutputStream outStream = new FileOutputStream(destination);
int bytesRead = 0;
while ((bytesRead = in.read(buffer)) != -1) {
outStream.write(buffer, 0, bytesRead);
out.println("File copied successfully ....");
plz reply me as soon as possible.
i will be very thankful
SaadThats the way it works. Cause servlet contaner doesnot allow other machines in the network to access other than machine which it came from as in case of applets. What you can do is if the other machine is also based on webserver or app server .. you can upload the file as it gets to that page do the process.
I would like to hear more on my comments..

Hi every1,
I have the following problem:
I need to store information in files on server, how can I upload a file to a server into a specified directory??
Tnx in advance,
Mort//the server side
ServerSocket acceptSocket = new ServerSocket(port);
while(true) {
Socket s = acceptSocket.accept();
Connect(s);
} // waits for client socket
void Connect(Socket s) {
in = new ObjectInputStream(s.getInputStream());
} // you can create a file object on the client side and send it through an object stream. You should probably make sure that file objects are synchronized. They most likely are. I've never tried this, but there's no reason why it wouldn't work. Make sure to start the output stream before the input stream or you'll get a hang up.
//the client side
s = new Socket(InetAddress ip,int port);
out = new ObjectOutputStream(s.getOutputStream());
out.writeObject(File file); //write the file object to the output stream
