Can viewObject get a parameter from sessionScope to binding variable?

hello,
using Jdev11g ADF Fusion application
Can viewObject get a parameter from sessionScope and assign into binding variable ? without using executeWithParameter
Thanks

A. Safwat,
As I said before, I was not trying to be offensive, but simply to explain some of the shortcomings of one solution over another. One of the reasons people give such short answers is that many questions (including this one) have been asked and answered many many many times before on the forum. As to my reasons:
1). Overkill - overkill because you are writing code to do what the framework already provides for you.
2). Not bind-variable friendly - you are gluing in literals into a SQL statement. That means that Oracle will have to hard parse the query for each new value of the filter clause, yielding to poor performance, particularly in a multiuser environment. It should ideally be done using bind variables.
3). Insecure (think about what happens if you put "'xyz' or 1=1" into the filterValue there) - not using bind variables is a security hole. Think through what happens if a filter criteria comes through like the one I mentioned.
4). Inflexible - because you are overriding executeQueryForCollection, this VO becomes inflexible and can only be used in this particular place. Using the declarative approach outlined by Timo is more flexible
5). Bad (ok, that's my opinion there) - OK, perhaps this was a bit offensive ;)
Please don't take a critique of a post as offensive, as I assure you it was not intended to be in that spirit. As I mentioned, I greatly appreciate when people point out issues/problems/etc with my ideas, as that is the best way for me to learn. I have in the past written applications that were not bind-variable friendly, and I learned the downsides the hard way (system was horribly non-performant) - I wish someone had reviewed my approach and told me "bad idea" before the application made it into production.
Respectfully,
John

ImageIO - javax.imageio.IIOException: Can't get input stream from URL

Hi,
I'm developing a program which accesses a given URL of an image and saves it to a file. However when I try this I get the following error:

     ... 2 moreThe internet connection I am using uses a proxy server and I think this is where the problem lies. I'm using Eclipse version 3.3 and I've tried changing the network settings to use the proxy's hostname and port but this still isn't working. I've also tried using System.setProperty("http.proxyHost", "hostname") and System.setProperty("http.proxyPort", "port") but that hasn't worked for me either. Below is my class in full.
import java.awt.image.*;
import javax.imageio.*;
import java.io.*;
import java.net.*;
public class ImageSave
     public static void main(String args[])
          try {
               URL url = new URL("http://www.example.com/image.jpg");
               BufferedImage image = ImageIO.read(url);
               ImageIO.write(image, "JPG", new File("image.jpg"));
          catch (Exception e) {
               e.printStackTrace();
}The error occurs with the line: BufferedImage image = ImageIO.read(url);
I have tried looking for a way to change how this specific method accesses the internet (e.g: a Proxy parameter with URLConnection) but there doesn't seem to be any.
Any help or suggestions would be greatly appreciated.
-Robert

Ah, that worked fine. I had thought of using that earlier but I was under the impression that the input stream would be HTML rather than an actual image. Not sure why.. Anyway, thanks very much for your help!
Here is the new code with your suggested revisions and a URLConnection to get the input stream:
import java.awt.image.*;
import javax.imageio.*;
import java.io.*;
import java.net.*;
public class ImageSave
    public static void main(String args[])
        try {
             // This is where you'd define the proxy's host name and port.
             SocketAddress address = new InetSocketAddress(hostName, port);
             // Create an HTTP Proxy using the above SocketAddress.
             Proxy proxy = new Proxy(Proxy.Type.HTTP, address);
             URL url = new URL("www.example.com/image.jpg");
             // Open a connection to the URL using the proxy information.
             URLConnection conn = url.openConnection(proxy);
             InputStream inStream = conn.getInputStream();
             // BufferedImage image = ImageIO.read(url);
             // Use the InputStream flavor of ImageIO.read() instead.
             BufferedImage image = ImageIO.read(inStream);
             ImageIO.write(image, "JPG", new File("image.jpg"));
        catch (Exception e) {
             e.printStackTrace();

Can not get the parameter?

I use a form to upload files,
like this:
<form name="gdform10" action="upload.jsp" ENCTYPE="multipart/form-data" method="post">
<input type="hidden" name="picName" value="wxds.jpg">
<input type="file" name="file">
<input type="submit" name="savePic" value="modify">
</form>
but I can not get the parameter picName in the upload.jsp,
like :
String pname = request.getParameter("picName");
but pname is null.

Hello,
In Jsp, if you want to upload file, you can't directly use "request.getParameter()".
There're two company provide components for you and it's free.
First is jspsmart company, it offer jspsmartUpload component and link is
http://www.jspsmart.com
Second is o'reilly, it offer MultipartRequest component and links is http://www.servlets.com/cos/javadoc/com/oreilly/servlet/MultipartRequest.html
for example, you use oreilly component.
<%@ page import="com.oreilly.servlet.MultipartRequest" %>
String saveDirectory = "c:\\Upload\\";
int maxPostSize = 5 * 1024*1024;
MultipartRequest multi= new MultipartRequest(request,saveDirectory,maxPostSize );
Enumeration filesname = multi.getFileNames();
while(filesname.hasMoreElements()){
String name = (String)filesname.nextElement();
FileName = multi.getFilesystemName(name);
File f = multi.getFile(name);
String ContentType = multi.getContentType(name);
ps. above codes is from book named "java server pages tech reference"

Can't get a picture from a plugged-in VHS player on Qosmio G20

Hi! Would be pleased if somebody could help me on the following:
Got notebook Toshiba-Qosmio G20
I can't get a picture from a plugged-in VHS player. I've installed the VHS player in accordance with the PC manual through the Monitor-in socket and the enclosed cable. There's also an interesting remark in the manual: "before installing any device through the Monitor-in port, you should tune the Terminal Shape parameter (socket shape)". But there's nothing said on how or where this tuning should be done.
HELP! PLEASE! My stupidity is embarrassing!
Many thanks in advance!

In fact I didnt find that Terminal Shape switch. Ive simply recorded the video from VHS player onto the notebook hard drive with WinDVD Creator 2 programme. And right after that I have encountered another problem the picture from the plugged-in VHS player was shifted downwards (the upper part of the frame was below, while the lower part was seen in the top of the screen). Ive tried plugging through S-Video and RCA, but it also didnt help. I would be very pleased if somebody could help me.

How can i get all values from jtable with out selecting?

i have one input table and two output tables (name it as output1, output2). Selected rows from input table are displayed in output1 table. The data in output1 table is temporary(means the dat wont store in database just for display purpose).
Actually what i want is how can i get all values from output1 table to output2 table with out selecting the data in output1 table?
thanks in advance.

You could set the table's data model to be the same:
output2.setModel( output1.getModel() );

Can you get values back from a stored procedure via OUTPUT parameters?

Can you get values back from calling a stored procedure via OUTPUT parameters/variables? I call the SP via a SQL statement from a script either in a WF or DF.
I thought I read some reference that DI could not get the values from OUTPUT parameters but I could not find it again (don't know if it is in any of the documentation or referred to in a forum.
I did try a couple of tests but it did not reutrn any values via OUTPUT. But before I give up I thought I'd see if you could and maybe I needed to change something.

This isn't exactly an answer to your question, but I'll point out that, given that you're resorting to a SQL script in the first place, there's no reason you can't also turn the output parameters into a regular result or record set. (The following uses T-SQL, although I think it's pretty generic.)
declare @param1 int, param2 varchar(100), @return int;
exec @return = proc @param1 = @param1 output, @param2 = @param2 output;
select @param1 as param1, @param2 as param2;
That is, to get from output parameters to a "regular" output from the SQL script isn't much of a leap...

How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system. Not enough memory to upgrade.

How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system. Not enough memory to upgrade.

You can't. iCloud is not for general file backup from a Mac. It's for backup up and syncing data between mobile devices and and Macs and The following is from this Apple document: iCloud: Backup and restore overview.
iCloud automatically backs up the most important data on your (mobile) device using iOS 5 or later. Once you have enabled Backup on your iPhone, iPad, or iPod touch .....
What is backed up
You get unlimited free storage for:
Purchased music, movies, TV shows, apps, and books
Notes: Backup of purchased music is not available in all countries. Backups of purchased movies and TV shows are U.S. only. Previous purchases may not be restored if they are no longer in the iTunes Store, App Store, or iBookstore.
Some previously purchased movies may not be available in iTunes in the Cloud. These movies will indicate that they are not available in iTunes in the Cloud on their product details page in the iTunes Store. Previous purchases may be unavailable if they have been refunded or are no longer available in the iTunes Store, App Store, or iBookstore.
You get 5 GB of free iCloud storage for:
Photos and videos in the Camera Roll
Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
App data
Home screen and app organization
Messages (iMessage, SMS, and MMS)
Ringtones
Visual Voicemails
But not from a Mac. If you want to backup your photos and other important files I suggest you get an external hard drive and use it with Time Machine.

How can I get all photos from the camera roll onto the photo stream so they will share between iphone and ipad?

How can I get all photos from the camera roll, and all new pictures taken, to get on the photostream so they can share between iphone and ipad?

When turning PhotoStream on with photos available in the Camera Roll, only photos captured by the iPhone or saved on the iPhone are placed in the PhotoStream.
For all photos that were in the Camera Roll prior to turning PhotoStream on, import the photos with your computer and add the photos to your PhotoStream on your computer.

Backing up an iOS device will copy some data to a backup file within iTunes, but this excludes all media. You can also transfer iTunes Store purchases from the iDevice to iTunes but, without using a third-party tool, nothing else. As long as you do not sync the iPod with your new library, the media that's on it will remain ... for as long as it keeps functioning, is not lost, stolen, eaten by the dog, ...
You may also have an option to recover your previous library from your old laptop; as long as its hard drive isn't fried, a computer repair store or technician may be able to extract the drive, mount it in an external enclosure, and copy your data to another PC. Whatever you choose, there is no real alternative to having all your media on your computer, managed by iTunes, and regularly backed up to another device/location.

I want to develop a software with AirPaly service for business things. How can I get the permission from Apple?
This one is used in Windows laptop, and I want it support AirPlay service, but Apple doesn't publish the AirPlay protocol.
Many thanks.

Create a developer account, then access he developers forums and see if you can find the information that way
The other option would be to simply contact Apple directly.
