How to write file at server end?
Hi,
I use a af:inputFile component to receive uploaded files. And want to write files to the directory of server. However, when execute java.io.File.createNewFile(), it throw exception. How to resolve it?
import org.apache.myfaces.trinidad.model.UploadedFile;
import javax.faces.event.ValueChangeEvent;
import java.io.InputStream;
import java.io.File;
public class UploadFileHandler {
public void doUpload(ValueChangeEvent event) throws IOException {
File file = new File("C:\temp.txt");
*file.createNewFile();* //Error happen here.
}
Hi Cheney,
It is good practice to use System.getProperty("file.separator") instead of hardcoding "/" or "\" .
Though your issue is resolved by using "//", you might want to consider changing to the above.

How to write file to server side?
hello,
Could anyone pls help me...
I just want to see an example how can I write to a file that is placed at the server(save place as the applet).
p.s. I have been successfully read a file from there...
Suppose I have signed the applet (self-signed), anymore security problem I need to pay attention to?
Thanks a lot!!hi mandy, from the applet u can send the file to be written into the server to a servlet running in server and the servlet can in turn write the file into the servlet. by applet - servlet communication, u can easily read and write files to the server.

How to write file to server using applet?
Please help!!!!!!!!!!
Why didn't this work?
URLConnection ucon = url.openConnection();
ucon.connect();
ObjectOutputStream outStream = new ObjectOutputStream(new BufferedOutputStream(ucon.getOutputStream()));
outStream.writeObject(linkHolder);
outStream.close();
.............As my applet run, the message printed out with my catch is: "java.net.UnknownSerivceException: Protocal doesn't support this output."
However, the reading from server is fine:
ObjectInputStream inStream = new ObjectInputStream(new BufferedInputStream(url.openStream()));
links = (LinkHolder)inStream.readObject();
inStream.close();
....I really appreciate for your help.
JTomThis file resides on server not local machine. I'm just testing on my local PC for now.
By the way, applet doesn't allow any kind of communication to client machine or others, but only to the server it resides in; according to the specs.
To get a url connection you need a server. You send
the output to the server(some servlet or similar
program running on server).
But for file you don't need a server. You can open a
file on your local machine if just have file
permissions. There is no server involved here. -
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);

I have questions regarding notes section , like how I write notes and they end up my my wife's phone !!!!!!
Yes, as Josh P said, I can see that happening if you sync with iTunes on the same Computer and the same mail account. Under the info section, advanced, I bet notes is checked for both of the devices..everything else might be un-checked, but notes might be checked for both devices...

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 -

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 Dave1) 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. -
How to read file from server if I have a logical file path?
Hi guys,
I'm having a pretty "on the run" question,
My program is currently reading a file from server using "open dataset" with file path like this (just example)
/usr/interface/abc/bcd/testfile.dat
Now I got a requirement to make it more consistent to read files, instead of reading that physical file name, I should read the files from a specific folder using logical path.
So I go to T code "FILE" and created a logical path called ZABC_FILE_PATH, unix compatible, with physical path is (for example),
/usr/interface/<sysid>/<client>/<filename>
My question is, can I still use open dataset statement to read this? if yes, how do I do that? If no, there should be alternative way, please let me know what you think. Thanks,Thanks all, I figured it out.
ONe thing is that typo double quote
The other thing is the importing part, I need the full file path.
CALL FUNCTION 'FILE_GET_NAME_USING_PATH'
EXPORTING
CLIENT = SY-MANDT
logical_path = 'ZABC_MY_LOGICAL_FILE_PATH'
* OPERATING_SYSTEM = SY-OPSYS
* PARAMETER_1 = ' '
* PARAMETER_2 = ' '
* PARAMETER_3 = ' '
* USE_BUFFER = ' '
file_name = v_1
* USE_PRESENTATION_SERVER = ' '
* ELEMINATE_BLANKS = 'X'
IMPORTING
FILE_NAME_WITH_PATH = v_what_I_need
* EXCEPTIONS
* PATH_NOT_FOUND = 1
* MISSING_PARAMETER = 2
* OPERATING_SYSTEM_NOT_FOUND = 3
* FILE_SYSTEM_NOT_FOUND = 4
* OTHERS = 5
I really appreciate your contributions, thanks again! -
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..
Suggestions ??

How to write file in user's local desktop
Hi,
Using the WriteFile action, i can write the file in inetpub/wwwroot in server.
Is there any way to write the file in user's local drive folder?
Although now i am writing the file to server and allowing the user to access it through URL but I suspect that there could be user concurrent issue or file contamination issue.
Constraint - The file should open with the default name.
If i try to open a local copy to the user (thru SaveasCSV() or URL) and allow the user to save the copy then the default name appear as Illumniator.
Regards,
AnilI think your current approach of saving to the web location and providing the user access via URL is the best approach. From a security standpoint I can't see that writing directly to a user's desktop/laptop would be a good idea.
If you are worried about naming or concurrency issues, then create sub folders that match their user name, or devise a naming convention that allows the objects to be unique between users and purpose. -
How to write data at the end of doc in reverse order?[CS6-jsx]
I need to move all my spec texts entries at et end of doc. To keep correct reference in all found entries i have to process in reverse order
for (i = mFound.length-1; i>=0; i--){
...etc
but can't to think up, how to place entries in write order at the end.
String:
mStory.insertionPoints.item(-1).select();
app.paste();
does not work properly (of course). It makes this:
10.
9.
8.
7.
6.
...etc
How to get
1.
2.
3.
4.

How to write files to the filesystem with portal/plsql
Hi,
is there a way to write files to the filesystem via Portal?
Or can i call an external programm (perl, php) to do so, while portal writes further information to database?
thank you for the help
Ralf SchmittHi Ralf,
my primary task is to publish download-links to files stored ... somewhere as a linklist. I tried to store and download files to/from the database but i cant get it to run. Upload works, download doesn't.
(i'm not talking about a single form-query-download-link! I need a report-like linklist)If you want to do this you'll have to write some code but sure it's possible - i did it myself.
The links in the link list in your report should call a stored function retrieving the files from Wwdoc_document or whatever is the document table defined in your DAD. Simply select BLOB_CONTENT into a BLOB variable from the table, provided you know what file to read :-) The function would then read the BLOBs and send them to the client's browser via DBMS_LOB - it's poor design but it works just as smooth as it could and it's really performing. This would simply display the file into your browser or prompt for file save location, depending on what browser you are using and its client settings.
I guess this is not so clear, if you want some more details feel free to e-mail me at [email protected]
Another way would be to use wpg_docload to both download and upload files to/from the DB.
Now i try to figure out if it is possible to store the files to the filesystem and write only additional info like description or path into db.Again, yes, it is. I can't recall exactly how I did it ^_^ but the trick is to create a virtual directory in the DB - pointing at a physical directory on the file system you want to write to, and you have to have full read-write permission on the directory itself, and its path must be included in the utl_file_dir database parameter. Then you use both COM Automation or UTL_FILE to write files.
would it be possible to let a portal-form write info to the db and then pass the file to a php-script?
regards,
Ralf Schmitt
