Also i have to give user an option to view existing file attachments. I'm Planing to use BLOB in database table to store files.
Any help in this regards is appreciated

How to read and write(a file .txt) from a URLConnection

I try to read and write on one URLConnection. Is it possible ? How can i make it ?
The reading part of my application work's but not the writting part
That's a part of rhe code that i use to write :
String Line = "Hi";
MyUrl = new URL(this.getCodeBase(), FichierEvenement) ;
Con = MyUrl.openConnection() ;
Con.setDoOutput(true);
Con.setDoInput(true);
Con.setUseCaches(false);
Dos = new DataOutputStream(new BufferedOutputStream(Con.getOutputStream( )));
Dos.writeUTF(Line);
Please help me :)

What are you doing with the bytes written to the OutputStream? This info would help, but i do have a suggestion. I ran into this problem when trying to write strings using writeUTF. The output was all screwed up. So, maybe change your string to a character array. That way Unicode is displayed properly. This in conjunction with writing to an .html file instead of to the connection itself might work.

How to read and write to file on server

can any body tell how to read or write to a file on server, like where do i keep the file and what does the path look like......on server
stand alone i am reading and writing into file but when it comes to server i am confused how it works...i mean the path

The Path needs to be absolute:
For example in Unix it would look like:
/usr/paz/Test.txtIn Windows it would look like:

How to Read and Generate XML file from java code.

hi guys,
how to read the xml file (Condition :we know only DTD or Shema only).
How to Generate the new xml file ?(using Shema )
And one more how directly Generate the xml from DB?
Pleas with code or any URL

Using XMLbeans you can generate Java objects from an XSD schema (perhaps DTDs aswell)
Then you can create an instance of the Document object and ask it to write itself.
This will create an XML document complient to the schema.
XMLBeans generates a "type" safe DOM where you can only ever have a structure compilent to you schema.

How to read and write a file in unicode?

Hello!
I have a problem with reading and writing files which are saved in unicode. with my current code I get strange boxes in my text
Do you need a special Reader/Writer for this?
Please, help me if you have any ideas.
cheers
import java.io.*;
import java.util.*;
public class StreamConverter {
   static void writeOutput(String str) {
       try {
           FileOutputStream fos = new FileOutputStream("test_uni.txt");
           Writer out = new OutputStreamWriter(fos, "UTF8");
           out.write(str);
           out.close();
       } catch (IOException e) {
           e.printStackTrace();

   public static void main(String[] args) {
        String inputString = readInput();
        writeOutput(inputString);
}

Are you saying there's only the three boxes at the beginning, and the rest of the text is okay? That sounds like a Byte Order Mark (BOM). The BOM is optional for UTF-8, but Java's I/O classes act like it's forbidden. They should check for it when reading so they can skip over it, but (for now, at least) we have to do that ourselves.
All you have to do is read the first three bytes from the InputStream and compare them to the BOM. If they match, you start reading the text from that position; otherwise you reset the InputStream and start reading from the beginning.

How to read and write a string into a txt.file

Hi, I am now using BEA Workshop for Weblogic Platform version10. I am using J2EE is my programming language. The problem I encounter is as the above title; how to read and write a string into a txt.file with a specific root directory? Do you have any sample codes to reference?
I hope someone can answer my question as soon as possible
Thank you very much.

Accessing the file system directly from a web app is a bad idea for several reasons. See http://weblogs.java.net/blog/simongbrown/archive/2003/10/file_access_in.html for a great discussion of the topic.
On Weblogic there seems to be two ways to access files. First, use a File T3 connector from the console. Second, use java.net.URL with the file: protocol. The T3File object has been deprecated and suggests:
Deprecated in WebLogic Server 6.1. Use java.net.URL.openConnection() instead.

How do I migrate files created in a Windows OS to a new external drive that is formatted as a MAC drive. I want to read and write these files back to the new drive.

How do I migrate files from an external hard drive created in a Windows OS to a new MAC external drive? I want to read and write these files to the new drive.

If all you're trying to do is move the files from the Windows external to the Mac external, you can simply connect them both to the Mac and drag the files from the Windows drive to the Mac drive. If you want to move the files back and forth between them, you'll need to establish the format of the Windows external. Macs can read and write to FAT32 and exFAT (which can handle files larger than 4GB) formatted drives but can only read NTFS formatted drives without additional software. With the Windows drive connected, you can check its format with Disk Utility.

How to read and write on ntfs partitions??

Hello everyone, thanks for viewing my post. I want to know how to read and write on ntfs partitions under sata hd on my arch64 system. I'm using kde as my de and dolphin does sees it but can't access it anyway. I didn't had problem so far on mounting usb drives it just automounts maybe because it is a fat partition not a ntfs? Please I need your help...Thanks in advance:)

You will most likely need to rework your fstab. The one from my desktop is shown below. If you want regular users to be able to access the partition, then you will need to change the gid option as I have done. Although you could create a group just for people you want to have access.
You will need to know the device that your windows partition is held on of course. In my case it is my first hard disk, first partition, hence /dev/sda1.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
none /dev/pts devpts defaults 0 0
none /dev/shm tmpfs defaults 0 0

/dev/mapper/nvidia_fbgfhehd6 swap swap defaults 0 0

/dev/sdd1 /mnt/andromeda vfat defaults 0 0
/dev/sda1 /mnt/windows ntfs-3g defaults,user,gid=users 0 0
My XP partition is set to mount automatically, as I regularly interchange documents between the OS's.
Hope that helps.

Read and List the Files from Remote Webserver Path

Hi All,
I have requirement where i need to Read and List the files from a Folder of Remote webserver path using JAVA.
Remote webserver is within the network only...No Firewall and also Access is given to Read the folder. No Issues on this.
Folder will just contain some PDF files...
I just need to display the PDF file names available in the Folder..
No need to read the PDF File...Only required to read the folder to list the file names in it.
Looking forward some workaround to this.
Thanks and Regards.

I need to read the folder from a webserver path of different machine...
File dir = new File( prop.getProperty("inputPath"));
File[] files = dir.listFiles(fileFilter);
final String match=siteName;
     final String type=reportType;
     Calendar c1 = Calendar.getInstance();
     c1.add(Calendar.MONTH, - Integer.parseInt(prop.getProperty("filterMonths"))); //Filters reportes generated in last X months (X picked from config file)
     final long filterDate = c1.getTime().getTime();
     FileFilter fileFilter = new FileFilter() {
     public boolean accept(File file) {
     long fileLastModiDate = file.lastModified();
     if((fileLastModiDate >= filterDate) && (file.getName().toLowerCase().startsWith(match)) && ( (type.equals("M") && file.getName().indexOf("WIP")==-1) || ((!type.equals("M") && file.getName().indexOf("WIP")!=-1)) ) ) {
          return true;
     }else {
          return false;
Here it works fine if the input path is local machine..
But i need to know how to give the input path as WEBSERVER PATH of different machine??
