How to list the content of a URL

Hi All,
I am wondering whether the method of listing the content of a URL, is the same as listing a directory on a local system? The listing of a local directory can be achieved with the following code for example:
 File dir = new File("directoryName");
 String[] children = dir.list();
 if (children == null) {
 // Either dir does not exist or is not a directory
 } else {
 for (int i=0; i<children.length; i++) {
 // Get filename of file or directory
 String filename = children;
// It is also possible to filter the list of returned files.
// This example does not return any files that start with `.'.
FilenameFilter filter = new FilenameFilter() {
public boolean accept(File dir, String name) {
return !name.startsWith(".");
children = dir.list(filter);
// The list of files can also be retrieved as File objects
File[] files = dir.listFiles();
// This filter only returns directories
FileFilter fileFilter = new FileFilter() {
public boolean accept(File file) {
return file.isDirectory();
files = dir.listFiles(fileFilter);However, I am not sure whether it is as simple as replacing "directoryName" with "http://www.abc.com/photos" when using java.net.*.
I am automating a task to download all photos in a gallery at certain website.
Any assistance would be very much appreciated.
Many thanks,
Jack

Hi paulcw, JoachimSauer,
Thanks for answering to this post.
I am only trying to automate some downloads of quite a of photo albums of relatives overseas. It only takes a few weddings to take hours to download. Moreover, the reason for having made the photos on the Internet so that the relevant parties can do their own download at their convenience for free as opposed to costing the individual to spend time and money on burn dozens of DVDs... After all, this is information age we are living in.
Lastly, I am hoping to use the getContentType() method to determine the exact type of image such as jpg, gif, etc but doesn't appears that it is doing the right job. Is there any other way to do this instead?
Thanks a lot again,
Jack

How-to list the contents of a Data Pump Export file?

How can I list the contents of a 10gR2 Data Pump Export file? I'm looking at the Syntax Diagram for Data Pump Import and can't see a list-only option.
Regards,
Al Malin

use the parameter SQLFILE in the impdp which writes all the sql ddl's to the specified file.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14215/dp_import.htm
SQLFILE
Default: none
Purpose
Specifies a file into which all of the SQL DDL that Import would have executed, based on other parameters, is written.
Syntax and Description
SQLFILE=[directory_object:]file_name
The file_name specifies where the import job will write the DDL that would be executed during the job. The SQL is not actually executed, and the target system remains unchanged. The file is written to the directory object specified in the DIRECTORY parameter, unless another directory_object is explicitly specified here. Any existing file that has a name matching the one specified with this parameter is overwritten.
Note that passwords are not included in the SQL file. For example, if a CONNECT statement is part of the DDL that was executed, it will be replaced by a comment with only the schema name shown. In the following example, the dashes indicate that a comment follows, and the hr schema name is shown, but not the password.
-- CONNECT hr
Therefore, before you can execute the SQL file, you must edit it by removing the dashes indicating a comment and adding the password for the hr schema (in this case, the password is also hr), as follows:
CONNECT hr/hr
For Streams and other Oracle database options, anonymous PL/SQL blocks may appear within the SQLFILE output. They should not be executed directly.
Example
The following is an example of using the SQLFILE parameter. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. See FULL.
impdp hr/hr DIRECTORY=dpump_dir1 DUMPFILE=expfull.dmpSQLFILE=dpump_dir2:expfull.sql
A SQL file named expfull.sql is written to dpump_dir2.

How to organize the content of MANIFEST.MF

Most of the jar files contain a file named META-INF/MANIFEST.MF, and it provides some information about the class in the jar files, but when I execute the code below, I can't output all of the jar file name in the eclipse project's classpath.
import java.net.URL;
import java.util.Enumeration;
public class TestClassLoader {
public static void main(String args[]) throws Exception {
Enumeration<URL> en = TestClassLoader.class.getClassLoader().getResources("META-INF");
while (en.hasMoreElements()) {
URL metaInf = en.nextElement();
System.out.println(metaInf.toExternalForm());
So I want to know how to organize the content of MANIFEST.MF file to output the file name

getResources doesn't do what you apparently think it does. The resource path still has to be an exact match, but getResources allows for the possibility that the same resource path may occur multiple times on the class path.
You could use it to access all the MANFEST.MF files on the classpath but you'd need to full resource path "META-INF/MANIFEST.MF"
The code you've written doesn't access the contents of the manifests, of course. To access the contents of manifests use java.util.jar.Manifest objects.

How to handle the contents of a carousel

Hi,all
Now I have a trouble in how to handle the contents of a carousel.
I use codes below:
          locator=(PMTElementaryStream es).getDvbLocator();
          serviceDomain.attach(locator);
          dsmccObject=new DSMCCObject(serviceDomain.getMountPoint().toString());
          file=new File(serviceDomain.getMountPoint().toString());
          content= file.list();
to get some file or directories, such as *.png, *.class, *.mpg, xml, MHPdataloader, sport, and so on.
How can I do for next procedure.
Thank you.

What do you want to do next? You can create a DSMCCObject that refers to one of the files in your carousel, and use this to control the loading and caching of that file. To actually read a file, however, you will need to create a FileInputStream or RandomAccessFile that refers to that file. You can then use this like any other file access.
This may help you:
// create a new ServiceDomain object to represent
// the carousel we will use
ServiceDomain carousel = new ServiceDomain();
// now create a Locator that refers to the service
// that contains our carousel
org.davic.net.Locator locator;
locator = new org.davic.net.Locator
("dvb://123.456.789");
// finally, attach the carousel to the ServiceDomain
// object (i.e. mount it) so that we can actually
// access the carousel. In this case, we don't specify
// the stream containing the carousel in the locator, so
// we pass in the carousel ID as part of the attach
// request
carousel.attach(locator, 1);
// we have to create our DSMCCObject with an absolute
// path name, which means we need to get the mount point
// for the service domain
DSMCCObject dsmccObj;
dsmccObj = new DSMCCObject(carousel.getMountPoint(),
"graphics/image1.jpg");
// now we create a FileInputStream instance to access
// our DSM-CC object. Alternatively, we could create
// a RandomAccessFile instance if we wanted random
// instead of sequential access to the file.
FileInputStream inputStream;
inputStream = new FileInputStream(dsmccObj);
// we can now use the FileInputStream just like any
// other FileInputStream

How to see the content of a website's certificate?

I was not able to find how to view the content of a website's certificate using the Android version of Firefox.
On the desktop, this is possible via a 'view' button in the popup which appear when we click on the lock icon near the url bar. On Firefox for Android, I cannot find this button.

That's exactly what I wanted to point : it is missing.
I wish it can be added.

In order to read the content of the Redo Log files, you should use Logminer Utility
Please refer to the documentation for more information:

I am thinking of buying a MacBook Air and am wondering how to get the content of my iPad into iTunes.

I have iTunes on an old pc and am thinking of buying a MacBook Air. I am wondering how to get the content of my iPad on to the Mac as I know that sync only happens in one direction, from pc to device. I assume therefore that when I attach my pad to the new Mac it will sync to an empty iTunes and I will have lost all the content of my pad. I know I can restore purchases, but what about contacts, calendar, photos and music not purchased from apple. I have a fairly recent backup on a pen drive but it is a usb2 device and is formatted for a pc. Any advice would be appreciated.

Do I copy my media library or from a backup. I have a backup on my pc and on an external drive. This drive is usb2 and formatted for windows so I can't connect it to a MacBook Air to make the transfer. Equally I don't think there is a way to connect the 2 computers via a cable ie usb2 one end and usb3 the other. Will the computers talk to each other via wifi if I enable home share although I think this is only for music which still leaves contacts, mail etc.
I am sorry to be such an ignoramus but any further help would be appreciated.

Help me...How to read the content if "Transfer-Encoding:chunked" is used?

I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
public class HTTPResponseReader extends HTTPMessageReader
    String statusCode;
    public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
BufferedInputStream distream = new BufferedInputStream(istream);
retrieveHeader(distream);
StringTokenizer st = new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
versionProtocol = st.nextToken();
statusCode = st.nextToken();
String s;
while (st.hasMoreTokens())
        s = st.nextToken();
        if (s.equals("Transfer-Encoding:"))
       transferEncoding = new String(st.nextToken());
     if (s.equals("Content-Length:"))
       contentLength = Integer.parseInt(st.nextToken());
     if (s.equals("Connection:"))
      connection = new String(st.nextToken());
      if (connection.equals("keep-alive")) mustCloseConnection = false;
   retrieveBody(distream);
}After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
Can anybody help me.
Thanks in advance...

Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)

How to read the content of a text file (by character)?

Guys,
Good day!
I'm back just need again your help. Is there anyone knows how to read the content of a text file not by line but by character.
Please help me. Thank you so much in advance.
Jojo

http://java.sun.com/javase/6/docs/api/index.html
package java.io
InputStream.read(): int
Reads the next byte of data from the input stream.
Implementation:
InputStreamReader
An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

Hi Gazpan,
Thanks for visiting Apple Support Communities.
I recommend using the steps in this article to back up your iPhone if possible:
iOS: Back up and restore your iOS device with iCloud or iTunes
http://support.apple.com/kb/ht1766
You may also find this advice helpful for your situation:
What to do before selling or giving away your iPhone, iPad, or iPod touch
http://support.apple.com/kb/ht5661
If you no longer have your iOS device
If you're using iCloud and Find My iPhone on the device, you can erase the device remotely and remove it from your account by signing in to icloud.com/find, selecting the device, and clicking Erase. When the device has been erased, click Remove from Account.
If you're unable to complete either of the above steps, you should change your Apple ID password. Changing your password won't remove any personal information that is cached on the device, but it will make sure that the new owner can't delete your information from iCloud.
Cheers,
