Read a bfile and write its contents in a file stored in my hard disk

I will try to describe my problem as clearly as I can.
I have created a table that includes a LOB column "BFILE"
Then I'm trying to READ the BFILE stored in our database using the
DBMS_LOB package.
so far so good.
Now I want to write these data that I have read in the step above in a file
saved in my local disk. The problem is, since the file in databse is
stored as binary and I read Raw Data , I cannot create an exact copy of this
file. It seems that It doesn't write the RAW data in the binary format.
I have used the DBMS_LOB.READ to read the data and it works fine.
Now I want to create a file in my local disk and dump the data that I have
read from the BFILE that has been initially stored in the database.
Is there any solution to this problem?
I hope to hear from you soon
Thanks in advance

I used CFHTTP to get the page and then used a cffile to write
the #cfhttp.filecontent# into the new file!

Hi,
I am trying to get a feed of my ebay store listings to load
into froogle. Unfortunately, ebay provides the feed as a website
not a file and froogle (via GoogleBase) needs the file to be
submitted as an XML file.
Is there a way to use something like cfhttp to load up the
page where the feed is located, scan the page and write it's
contents into an XML file that I can then load up to GoogleBase???
thanks for the help.

How to create a file and store its contents into another file?

Hi,
I'm having some trouble trying to create a code where I have to to create a file and store its contents into another file?
I read the API, but I'm not certain how this file thing works.
Here's my code so far:
public static void main(String[] args) throws Exception
          File file = new File("tasks.txt");
          if (file.exists())
               System.out.println("File already exists");
               System.exit(0);
          Scanner scan = new Scanner(System.in);
          Scanner scan2 = new Scanner(System.in);
          //Scans the input line by line
          scan.useDelimiter("\\n");
          //Scans the input by tabs
          scan2.useDelimiter("\\t");
          PrintWriter outputs = new PrintWriter("newtasks.txt");
          outputs.print("ok");
          outputs.println(3);
          outputs.close();
     }

I managed to change my text into uppercase, but how do I store the uppercase content into another file.
-So this is what I did so far, I took a text file and modified its strings to uppercase.
-Now I need to put those modified strings into another text file, is there a way where I can do that with my current code?
-I already tried printwriter, but it doesn't seem to work
public static void main(String[] args)throws IOException
          //Task[] oneHundredTasks = new Task[100];
          String uppercase;
          String combine;
          Scanner scan = null;
          FileInputStream in = null;
        FileOutputStream out = null;
        PrintWriter output = null;
        try
             scan = new Scanner(new BufferedReader(new FileReader("tasks.txt")));
             scan.useDelimiter("\\n");
             scan.useDelimiter("\\t");
            while (scan.hasNext())
                 if(!scan.hasNext())
                      scan.next();
                 combine = scan.next();
                 uppercase = combine.toUpperCase();
                 System.out.println(uppercase);
        finally
            if (scan != null)
                scan.close();
        //The program will try the input and output files
        try
             in = new FileInputStream("tasks.txt");
            out = new FileOutputStream("newtasks.txt");
            int c;
            //The number "-1" is used to indicate that it has reached the end of the stream.
            while ((c = in.read()) != -1)
                out.write(c);
        finally
            if (in != null)
                in.close();
            if (out != null)
                out.close();
     }

Can a servlet read a jsp file and display its contents?

Hi,
I would like to know if Servlets can read a Jsp file and display its contents.. Right now for our website, I am using a html file to be displayed after a successful post operation through the Servlets...
-Thanks!

I posted this in another thread.
Here's some code that reads using a URL. This doesn't work with JSPs as the server executes JSP when it connects but it's useful for other file types. Note that the filename is a URI</h1>This is <code>show.jsp</code></h1>
<hr>
<%! String file = null; %>
<%! java.io.InputStream is = null; %>
<%
file = request.getParameterValues("filename")[0];
try {
is = (new java.net.URL(file)).openStream();
} catch (java.io.IOException ioe) { out.write(file + " not found!<br>"); }
java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(is));
String line = "";
%>
<pre>
<%
while((line = in.readLine()) != null) {
%>
<%=line%>
<%
%>
</pre>

Reading a properties file in a servlet and passing its contents to a JSP pa

Hi all,
I'm totally new to Servlet pgmg n JSP. Please can ne1 tell how to read a simple properties file (in a servlet) and pass its contents to a JSP page.Actually the reason is to fill a combo box in a JSP page with the contents of a properties file.If calling a servlet for the same is d best way to do that, plz can ne1 tell me :
1> whether to override the doPost method in the servlet in which to read d file using FileInputStream
2> Putting the contents in an array and then how to pass this array to the JSP page.
Thanks,
deepthy.

I'm using a properties file to let my web application know what the name of the database is. I'm using an abstract class GeneralDao which will be extended by all the DAO's (Data Access Objects or java classes containing SQL statements).
Here's the code :
protected Connection getDatabaseConnection()
          throws Melding
     Connection dbconn = null;
     ResourceBundle resBundle;
     try
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     resBundle = ResourceBundle.getBundle("gcoConfig");
     String dbConnectie = resBundle.getString("databaseconnection");
     gcoLogger.debug("lezen databaseconnection in resourceBundle " );
     dbconn = DriverManager.getConnection(dbConnectie);
     } catch (InstantiationException exc)The ResourceBundle is used to read the properties file, named gcoConfig.properties.
With the getString() command I read the content of the string named databaseconnection.
The gcoConfig.properties file is placed inside the folder C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\gco\WEB-INF\classes
The GeneralDao is placed in the folder C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\gco\WEB-INF\classes\org\gertcuppens\cluifDao.
So this class is placed some folder below the WEB-INF\classes folder of gcoConfig.properties.
And the content of the properties file is just one line :
databaseconnection=jdbc:mysql://localhost/cluif
If you want to let the JSP know what's inside the properties file, wrap the content in a Javabean, put it in the request or even the session and pass the control to the JSP.

}If you want to read the complete file content you must uncomment lines inside while instruction, like this
while (in.available() > 0) { // I prefer to test in.available like this, instead of !=
// append text to a StringBuffer (variable named sb here) or directly in a textarea.
sb.append(in.readLine());

HT5527 I have had my storage reduced once already. In the process they removed my "Save" mailbox and all its contents. I do notcare about contents so much as starting a new Save box. How? (OS X 10.7.5)

My iCloud storage is being reduced. I have already had it reduced once. In the process they removed my "Save" mailbox and all its contents. (One would think that that would be the last thing they removed. But they took that and the "Trash" mailbox, yet left several thousand old and read messages which were in my "Inbox".) I do not expect to get the "Save" contents back, but I would like to restore the "Save" mailbox, so that I can start from scratch saving msgs in it again. But I cannot figure out how to do that. When I go to "Mailbox" on the top line (between View and Message) and select New Mailbox I get a dialog box in which I can name a new mailbox. When I type Save, for the name of the new Mailbox I get a response; "The mailbox 'Save" already exists." But I cannot find it.
Thanks, Bill Burner

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

I am selling an iPad and cleared its contents and settings as given in other exchanges on this site but when I downloaded a new app on my iPhone it appeared on the iPad. Any idea why?

I am selling an iPad and cleared its contents and settings as given in other exchanges on this site but when I downloaded a new app on my iPhone it appeared on the iPad. Any idea why?

Sounds like you did not set back as new, or if you did you reset the iPad with your Apple Id again.
If it had been reset back as new it would have stayed at the Begin Setup screen, and you wouldn't have been able to see any Apps being downloaded, as you wouldn't have acccess to the Home Screen yet.
Follow Diavonex's post to restore the iPAd back to factory defaults, and that's it. It should be back to the Setup screen, without any Apple Id associated with it, and no Home screen visible.
