Finding the directory path in java

I need to check if a file exists or not before an action is taken. I used File class to get the handle of a file and and then used exist() function to check if it is there. But this function needs to full path to that file. I need to find a directory path at runtime as the application is deployed in different environment and wouldn't know the directory path in each environment. Could somebody help me on this. Thanks,

fBut this function
needs to full path to that file. I need to find a
directory path at runtime as the application is
deployed in different environment and wouldn't know
the directory path in each environment. Well, that can only you know where this file is on the different platforms. So maybee you can provide it as a user-input, a parameter to the program or be set in a settings-file which the program reads.
If you want the full path to the current directory where the java program runs, this works:
File f=...;
String absPath=f.getAbsolutePath();
File absPathFile=new File(absPath);Gil

Directory monitor in Java, help

Hey everyone,
I'm attempting to write a directory monitor in java but I'm stuck. I'm trying to find something in Java that is like FileSystemWatcher in .NET but I don't think java does. From what I read is that you have to continually poll the directory for changes. What I would like to know is that are there any events and/or signals raised when a changes are made so that one could catch and process them? If not, could someone explain how to simply poll the directory for changes?
Thanks

This is exactly what I need to do. Now, i already have been working on the last modified time comparison which is relatively simple. What I was stuck on was finding what was different between the two file lists. Would I have to iterate through the entirety of the list and compare each item to find what was different or is there a more efficient way of doing this?The simplest thing to do would be to use Collection's removeAll method to get the difference between the two. This will show you which files have been added (using newList.removeAll(oldList)) and which have been removed (using oldList.removeAll(newList)).
A few notes:
* removeAll modifies the collection on which you call it, so you'll need to make copies.
* File's equals method docs say: Returns true if and only if the argument is not null and is an abstract pathname that denotes the same file or directory as this abstract pathname. Whether or not two abstract pathnames are equal depends upon the underlying system. On UNIX systems, alphabetic case is significant in comparing pathnames; on Microsoft Windows systems it is not.
So you'll need to decide if that's good enough, or if you want to implement your own comparison for files. Also, it's not clear from the above how shortcuts or symbolic links are handled--whether the shortcut and the original are considered equal or not.
* Based on the above, you may get different results with a List vs. a Set, so play around and see which one better suits your needs.
* I think a directory's mod time only changes if you add or remove or rename files, or explicitly change it, as with the touch command in unix. I don't think modifying the contents of an existing directory cause that directory's mod time to be updated. If you want to know when a file has changed, you'll probably have to poll that file's mod time explicitly.
In light of the above, I suggest you start by writing a small program that does nothing but poll a directory every, say, 5 or 10 or 30 seconds and print out whether it's changed or not. Then, while that program is running, do various things like add, delete, rename, rename with same letters but different case, etc. and see if the program gives you the results you want. If not, you'll have to tweak it based on your findings.

Copying complete directory structure using java.io.File

Is there a solution to problem when you want to copy a complete directory structure using java.io.File class as you can copy when using FTP connection.

Is there a solution to problem when you want to copy
a complete directory structure using java.io.File
class as you can copy when using FTP connection.FTP does not have a command to transfer all the files in a directory. FTP clients implement this by invoking single file transfer for each file in a directory.

Hi there i am currently trying to develope a java
stored procedure and place it in oracle and will try
to use that procedure to send a message to a server
but then it doesnt seems to work. is it possible?And what do you do with exceptions in your java proc?
I haven't ever done it myself, but I would be very surprised if it wasn't possible. I also wouldn't be surprised to find out that you have to configure various things to allow it in Oracle itself.

How to avoid directory listing in java web applications.

how to avoid directory listing in java web applications.
That is on typing the url of the application it should not the directory listing. Welcome tag in web.xml doesnot fully solve the problem, since still the images folder etc is still accessible

I know of two ways.
If you're using tomcat and have access to the conf directory.
Edit your $TOMCAT/conf/web.xml. Find your default servlet properties and change
<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>to <servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>And restart your server. This will affect every directory on the server, and return a 405 directory browsing forbidden error.
Another way, is to place an index.jsp inside each directory with a simple one line redirect to your applications CONTEXT_PATH.response.sendRedirect("http://yourserver/yourapp/");This will only affect specific directories which contain these index.jsp files.
Hope this helps

Need to change the directory using the java program

hi,
can anyone give me the code to change the directory in the java program by using the system command.
as in C where we use the system call system("cd");
the same way how to do that in java. please help me with that!!!

Please search the forums for "runtime.exec", there are dozens of examples posted.
Although this may not do you any good, since changing the os's directory is not likely to change anything you're using in Java. What are you trying to do?

Newbie: IBM Directory Server LDAP Java Implementation

Good day friends,
I'm new in developing LDAP applications. I'm using IBM Directory Server v4.1 & need to develop a application (a web application - JSP/Servlet/EJB). I'm doing this as part of a Web project where i need to store the User Info of the registering user to LDAP server with proper Organisational Hierarchy & Privileges. I'm using Java for this application. I have the proper JNDI environment set for LDAP interaction. Can anyone provide me with a best practice/right procedure for implementing this, like searching for an entry, inserting/updating an entry & how to make use of Attributes provided in IBM DS 4.1.
I searched IBM redbook & others for this but without any success. All Prog references are pertaining to C & very minimal info for Java implementation. I found some info in other LDAP like Netscape & Novell, but there structuring is different from IBM DS. I would appreciate if anyone can throw some light on this regard. I would appreciate a complete Java Programmers Reference Guide for IBM Directory Server v4.1.
Thanking u in anticipation.
cheers,
J2EEDev.

I'm coping with the same question as you had.
Did you get any valuable information or a Java programmers reference guide for IBM directory server ?
If so, could you send me an url where I can obtain the required information ?
Thanks for your reply !

How to launch an Internet navigator with Java

In my java interface I would like to make a button which, when we clicked it, launch an internet navigator.
Is there a function which allows that?
Is this function platform-dependant?

hi,
if you mean in windows you could detect if it is NT (NT meaning NT, 2000 and XP) or not (98, 95, ME):
try {
     Properties systemProps = System.getProperties();
     String osVersion = systemProps.getProperty("os.name");
         if (osVersion.equals("Windows 98"))     {
          Runtime.getRuntime().exec("start helpFiles/help.html");
     else {
          Runtime.getRuntime().exec("cmd.exe /c start helpFiles/help.html");
}catch(IOException err) {
     JOptionPane.showMessageDialog((Component)e.getSource(), "Help File Not Found!", "ERROR!", JOptionPane.ERROR_MESSAGE, new ImageIcon("questionmark.gif"));
}

Accessing Active-Directory through a Java Swing Desktop Appl

I have a desktop application in which, I have an options window. In the window, I use a button to access the active directory(address-book) - when I click the button, the active directory window(the way the address book opens in microsoft-outlook) should open.
I wish to know where can I find information to implement this requirement. It would be even better if there's a solution posted!

Find how to do that from the command line. Perhaps there's an executable you can run or something like that. (Note that this is not a Java Programming question but something to do with your operating system.) Then use a ProcessBuilder to do that command-line thing.

Implementing a directory listener in java...!

Hi guys..!
I wrote a program that creates an Xml file when the program terminates. I want to write some kind of Listener that will listen the directory where the file is created. So, what I want is....as soon as the file is created, I want to be able to get the file from that directory and copy it to a different directory.
In addition, I also want to write a FTP program that will take the created Xml file and send to a different machine.
Does anyone have an idea on how to do that...??? Any help from you guys will be very appreciated...
Thanks...

to copy a file is not difficult, use something like this:
FileChannel sourceChannel = new FileInputStream(in).getChannel();
FileChannel destinationChannel = new FileOutputStream(out).getChannel();
sourceChannel.transferTo(0, sourceChannel.size(), destinationChannel);
sourceChannel.close();
destinationChannel.close();"in" and "out" are File objects.
see api docs of FileChannel for details.
ftp via java: i remember seeing it discussed here recently, ask google or forum search should help ...
