Writing a file with the OutputStream
I'm trying to upload a file using Java's included ftp functionality.
currently I'm trying to figure out how to upload a file. The connection and works.
The code I found for the ftp connection indicated that I should use the following code to upload..
URLConnection urlc = url.openConnection();
OutputStream os = urlc.getOutputStream();
I've read the documentation for the outputstream and looked for help tutorials on the web etc, but still haven't been able to figure out what I'm doing.
I need the output stream to write a file to the ftp server. I can get it to put a file there, but so far its just been an empty file. How do I get it to actually write the file with its contents etc.
thanks for the help
never mind :) I think I figured it out.
I just created a File object for the file, then opened a fileinputstream to read the file in and wrote that output using the output stream.
it seems to work.

PDF file transfer writing target file with the same source file name
Hi to all,
I want to transfer a PDF file from a SOURCE folder to a TARGET folder. My problem is that I want the target pdf file has the same name of the source pdf file. How can I do this? I have to look for some parameters in the sender or receiver channels?
Thanks to all.Hi Gabriele,
If you want to FTP the pdf file from source to target directory, use this blog. It doesn't require any IR devlopment.
/people/william.li/blog/2006/09/08/how-to-send-any-data-even-binary-through-xi-without-using-the-integration-repository
Also, In sender and receiver comm channels select "Set/Use Adapter specific message attributes" and "File Name" to get the same file name in the target directory.

hi,
as part of my requirement , i have to perform read and write operations of few files [ using the file upload control in my custom visual web part] and on submit button click.
but while writing these files - with the help of fileupload control - and when i use myfileupload.saveas(mylocation);
- i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
it throws system.unauthorizedexception.
i have given full control on that folder where i was trying to store my attached files. and also after following asp.net forums,
i have added iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
but unfortunately that didnt happen.
also
a) i am trying the code with runwithelevatedprivileges(delegate() ) code
b) shared the drive within the d :drive where i want o save the files.
c) given the full privieleges for the app pool identity- in my case , its
network service.
the other strange thing is that, the same code works perfectly in other machine, where the same sp, vs 2012 etc were installed .
would like to know, any other changes/ steps i need to make it on this server, where i am getting the error.
help is appreciated!vishnuS1984 wrote:
Hi Friends,
I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
public static void copyFiles(File src, File dest) throws IOException
// dest is a 'File' object but represents the C:\GetMe1 directory, right?
fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck! -

The issues i'm facing are:
When it is reading a row from MS-Excel it is writing to the .pdf file from last cell to first cell.( 2 cell in 1 place, 1 cell in 2 place like if the row has two cells with data as : Name of the Intern: Kesavulu Reddy then it is writing to the .pdf file as Kesavulu Reddy Name of Intern)
and the second issue is:
It is not recognizing the date format..it is recognizing the date in first row only......
Plz Tell me wht is the solution for this...

What is the max size of a zip file with the JDK1.5 ?
Hello everybody,
I'm a french student and for a project, I need to create a zip file, but I don't know in advance the number and the size of files to include in my zip.
I wish to know if someone have the answer to my question : what is the max size of a zip file with the JDK1.5 ? I believe that with the JDK1.3, the limit size of a zip was about 2Go, wasn't ?
Thank you for all answer !
Good day !
PS : sorry for my very poor english ;-)Here is all I have found for the moment :
...Okay, what about my suggestion of creating your own 10GB file?
Try this:import java.io.File;
import java.io.RandomAccessFile;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Random;
class Main {
public static void main(String[] args) {
long start = System.currentTimeMillis();
int mbs = 1024;
writeFile("E:/Temp/data/1GB.dat", mbs);
long end = System.currentTimeMillis();
System.out.println("Done writing "+mbs+" MB's to disk in "+
((end-start)/1000)+" seconds.");
private static void writeFile(String fileName, int numMegaBytes) {
try {
int numBytes = numMegaBytes*1024*1024;
File file = new File(fileName);
FileChannel rwChannel =
new RandomAccessFile(file, "rw").getChannel();
ByteBuffer buffer = rwChannel.map(
FileChannel.MapMode.READ_WRITE, 0, numBytes);
Random rand = new Random();
for(int i = 1; i <= numMegaBytes; i++) {
for(int j = 1; j <= 1024; j++) {
byte[] bytes = new byte[1024];
rand.nextBytes(bytes);
buffer.put(bytes);
rwChannel.close();
} catch(Exception e) {
e.printStackTrace();
}On my machine it took me 43 seconds to create a 1GB file, so it shouldn't take too long to create your own 10GB. Then try zipping that file.
Good luck. -
Suppress writing cache files with rwrun.exe
Hello,
we`re using rwrun.exe (9.0.4.2.0) with parameters to create pdf-files in a loop:
REPORT=mytest.rdf
USERID=scott/tiger@orcl
BLANKPAGES=no
DESTYPE=file
DESNAME=mytest.pdf
DESFORMAT=PDF
OUTPUTIMAGEFORMAT=GIF
CACHELOB=NO
Each process write a cache file in the directory \reports\cache. Reports eats the hard disk :-(
I`ve found the EXPIRATION command in the documentation, which defines the point in time when the report output should be deleted from the cache. But this command strictly runs with rwclient.exe and reports server, but Reports server isn`t installed on our server.
Can we suppress writing cache files with rwrun.exe?
SteffenHello,
Why don't you add a command del in your loop ?
Example:
del %ORACLE_HOME%\reports\cache\*.*

I'm using Numbers version 3.2.2.
Suddenly I cannot access my password protected Numbers file with the correct password. I have the correct password written down so I know I haven't made a mistake.
The response box that pops up says that the file cannot be opened. There are no other options for me to choose from.Also, I tried to open it through an older version of Numbers but it sent this error message.

I have a Macbook Pro running Leopard 10.5.8. I had a problem with my my operating system (my fault, I moved a file I shoudnt have) couldnt boot up but was able to boot up from a backup. I managed to repair my original system except now all the system folders, including hidden folders are littered with duplicate folders and files with the suffix (from old Mac). For the most part the dupes are an exact copy, but not always. I want to remove them to free up space and cant imagine duplicate folders in the /system/library are not hindering my computer. But I dont know where to start and am afraid of doing irreparable damage. Any ideas

I had some FCP projects on an old G3 tower that I finally want to finish. I was able to grab everything, media, etc. to my macbook pro but all of the Final Cut Pro actual movies/projects have turned into "linux executable files" that FCP X won't import.
I tried googling this issue but didn't really see any good answers. Would it be as simple as renaming the files with the .fcp extension? I can't recall if my old version (really old) of FCP saves projects as .mov or .fcp files, but I'm assuming I'm not the only person this has happened to.
Thanks for your help!I had some FCP projects on an old G3 tower that I finally want to finish.
What version of FCP was this? The project files can probably no longer be opened in the newer version of the OS. You could try adding the .fcp suffix, but I don't think it will help for this. Projects files are .fcp.
Regardless of the version, no legacy FCP projects will import into FCPX.
Media is a different matter. These are probably QuickTime .mov files. If these are appearing as Unix ececutables, they're probably not recoverable either. -
I can't decipher where (and why) the program is putting the HDR image in the grid. I stack all of my HDR source images so they are easy to track and manage. Other apps/plugins allow you to stack resulting images with their source image. That would be great if there's a way to set that in LR preferences.
Thanks, but this doesn't really answer the question about stacking the HDR file with the source files. Yes, it does put the file in the same folder, however many of my folders have 100s of images (that often look similar) and as far as I can tell, LR places them randomly in the sort order. It doesn't appear to put them at the beginning or end of the sort (usually by date), but somewhere randomly in the middle. Even if it could be made clear what method it is using to sort them, that would help locate one file among hundreds.
Ideally, however it should allow you to stack with the stacked source files. Is there anyway to do this? If not, is it a feature that could be requested? -
How can I create a file with the excel file type?
I work with forms 4.5 and I could create "TEXT_IO.FILE_TYPE", but with this I make a I/O TEXT file not a file with the characteristics from a excel file! Can somebody help me please?!?!?
Best regards,
Chris from PortugalThe extension file must be 'CSV' and not 'CVS'. It's better to separate your items by a ';'
The HOST command you have to execute after creating the file it's HOST(EXEL_PATH SPACE YOUR_FILE) OR Open the DOS PROMPT and type: Exel your_file_name. -
How can I overwrite a file with the same name in Content DB?
Hi All,
In Content DB if I upload a file with the same name as a previous one, the application shows the warning message:
" ...You cannot upload "XXXXXX.doc" to "Test 1" because an item with the same name already exists ..."
And the alternatives are "Create Version" or "Cancel" the operation. Is there any way to overwrite a previous file as we can do it in Oracle Files ?

Can anybody from the Content DB product development answer this question?

I also have a .csv file with the name of a jpeg in one column and a text description of each jpeg in a second column. Is there a way to automatically insert one jpeg (photo) and its corresponding text, each pair on one page, into a Indesign document?
I would also recommend to write the description into the meta data. This would allow to place a text frame above the image and it is possible to add meta information and file name automatically together with the image, when you place it or even in a prepared template.
Meta data information can be written easily in Bridge in the Meta File Workspace. -
After installing the latest update to Firefox onto Vista operating system the record part of real player no longer works, I think Mozila and Real are using a library file with the same name and the Mozila update is overwriting a Realplayer library file.
I was giong to say, "Help me, Adobe Joe Kenobi", but it looks like you're growing a beard waiting for an answer, too.
The same thing happened to me today. I trusted the "update" message since it was from Adobe, and apprently did so at my own peril. Now I get the "failed to load Core dll" message with a secondary reference to a memory address.
Just an observation, but what good are these forums when there are no answers? I see this problem as "Caused by Adobe Update", and would expect them to troublshoot and offer up a remedy. Since you've been waiting over two months with no response, I suppose it's time to trek off wasting more of my precious time to fix their problem. If I find the solution, I'll post it back to you.
May the Force be with you.
