How to load a image from database to image item in oracle 10 g form

I have stored some images in the Database Table with BLOB datatype. Now I need to load that image in the non database image item. Please advise. Thanks.

You need to have a print server installed to generate the pdf. Either use BI Publisher and it's desktop development tool or use FOP/Cocoon.. Adding an image with them is a little more involved..
Thank you,

How to load an image into blob in a custom form

Hi all!
is there some docs or how to, load am image into a database blob in a custom apps form.
The general idea is that the user has to browse the local machine find the image, and load the image in a database blob and also in the custom form and then finally saving the image as blob.
Thanks in advance
Soni

Pre-loading the Cache from Database during application start-up

We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

Hi Rob,
Thanks for pointing to the article: Pre-Loading the Cache
In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
What i am looking for is how to make this happen during application start-up. This is my first hurdle.
The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
public   void populateCache() throws SQLException
    Map<Long, Object> buffer = new HashMap<Long, Object>();
    int count = 0;
     List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
     log.debug("contractList size="+contractList.size());
     for(Contract contract : contractList)
         Long key   = new Long(contract.getId());
         Object value = contract;
         buffer.put(key, value);
         // this loads 1000 items at a time into the cache
         if ((count++ % 1000) == 0)
              contractCache.putAll(buffer);
             buffer.clear();
     if (!buffer.isEmpty())
          contractCache.putAll(buffer);
    }We would greatly appreciate your time in helping us resolving two hurdle blocks.

Hello,
The easiest way to load a blob is to use SQL loader.
This example comes from the utilities guide:
LOAD DATA
INFILE 'sample.dat'
INTO TABLE person_table
FIELDS TERMINATED BY ','
(name CHAR(20),
1 ext_fname FILLER CHAR(40),
2 "RESUME" LOBFILE(ext_fname) TERMINATED BY EOF)
Datafile (sample.dat)

How to insert a image file into oracle database

hi all
can anyone guide me how to insert a image file into oracle database now
i have created table using
create table imagestore(image blob);
but when inserting i totally lost don't know what to do how to write query to insert image file

Hi I don't have time to explain really, I did have to do this a while ago though so I will post a code snippet. This is using the commons file upload framework.
Firstly you need a multi part form data (if you are using a web page). If you are not using a web page ignore this bit.
out.println("<form name=\"imgFrm\" method=\"post\" enctype=\"multipart/form-data\" action=\"FileUploadServlet?thisPageAction=reloaded\" onSubmit=\"return submitForm();\"><input type=\"FILE\" name=\"imgSource\" size='60' class='smalltext' onKeyPress='return stopUserInput();' onKeyUp='stopUserInput();' onKeyDown='stopUserInput();' onMouseDown='noMouseDown(event);'>");
out.println("   <input type='submit' name='submit' value='Submit' class='smalltext'>");
out.println("</form>"); Import this once you have the jar file:
import org.apache.commons.fileupload.*;Now a method I wrote to upload the file. I am not saying that this is correct, or its the best way to do this. I am just saying it works for me.
private boolean uploadFile(HttpServletRequest request, HttpSession session) throws Exception {
        boolean result = true;
        String fileName = null;
        byte fileData[] = null;
        String fileUploadError = null;
        String imageType = "";
        String error = "";
        DiskFileUpload fb = new DiskFileUpload();
        List fileItems = fb.parseRequest(request);
        Iterator it = fileItems.iterator();
        while(it.hasNext()){
            FileItem fileItem = (FileItem)it.next();
            if (!fileItem.isFormField()) {
                fileName = fileItem.getName();
                fileData = fileItem.get();
                // Get the imageType from the filename extension
                if (fileName != null) {
                    int dotPos = fileName.indexOf('.');
                    if (dotPos >= 0 && dotPos != fileName.length()-1) {
                        imageType = fileName.substring(dotPos+1).toLowerCase();
                        if (imageType.equals("jpg")) {
                            imageType = "jpeg";
        String filePath = request.getParameter("FILE_PATH");
        session.setAttribute("filePath", filePath);
        session.setAttribute("fileData", fileData);
        session.setAttribute("fileName", fileName);
        session.setAttribute("imageType", imageType);
        return result;
     } And now finally the method to actually write the file to the database:
private int writeImageFile(byte[] fileData, String fileName, String imageType, String mode, Integer signatureIDIn, HttpServletRequest request) throws Exception {
        //If the previous code found a file that can be uploaded then
        //save it into the database via a pstmt
        String sql = "";
        UtilDBquery udbq = getUser(request).connectToDatabase();
        Connection con = null;
        int signatureID = 0;
        PreparedStatement pstmt = null;
        try {
            udbq.setUsePreparedStatements(true);
            con = udbq.getPooledConnection();
            con.setAutoCommit(false);
            if((!mode.equals("U")) || (mode.equals("U") && signatureIDIn == 0)) {
                sql = "SELECT SEQ_SIGNATURE_ID.nextval FROM DUAL";
                pstmt = con.prepareStatement(sql);
                ResultSet rs = pstmt.executeQuery();
                while(rs.next()) {
                   signatureID = rs.getInt(1);
                if (fileName != null && imageType != null) {
                    sql = "INSERT INTO T_SIGNATURE (SIGNATURE_ID, SIGNATURE) values (?,?)";
                    InputStream is2 = new ByteArrayInputStream(fileData);
                    pstmt = con.prepareStatement(sql);
                    pstmt.setInt(1, signatureID);
                    pstmt.setBinaryStream(2, is2, (int)(fileData.length));
                    pstmt.executeUpdate();
                    pstmt.close();
                    con.commit();
                    con = null;
            if(mode.equals("U") && signatureIDIn != 0) {
                signatureID = signatureIDIn.intValue();
                if (fileName != null && imageType != null) {
                    sql = "UPDATE T_SIGNATURE SET SIGNATURE = ? WHERE SIGNATURE_ID = ?";
                    InputStream is2 = new ByteArrayInputStream(fileData);
                    pstmt = con.prepareStatement(sql);
                    pstmt.setBinaryStream(1, is2, (int)(fileData.length));
                    pstmt.setInt(2, signatureID);
                    pstmt.executeUpdate();

Hi,
I am using oracle 10g , plsql developer. Can anyone help me in how to load the data from .csv file to oracle table. The table is already created with the required columns. The .csv file is having about 10lakh records. Is it possible to load 10lakh records. can any one please tell me how to proceed.

Have a look also at the FAQ link posted by Marwin.
There are plenty of examples also on the web.

How to load mutiple image

I'm trying to create a photo manager but I can't find a way to load multiple images onto my frame. I have a thumbnail class that makes thumbnails for an image (which is a modified version of the class ImageHolder from FilthyRichClient)
public class Thumbnails {
     private List<BufferedImage> scaledImages = new ArrayList<BufferedImage>();
private static final int AVG_SIZE = 160;
* Given any image, this constructor creates and stores down-scaled
* versions of this image down to some MIN_SIZE
public Thumbnails(File imageFile) throws IOException{
          // TODO Auto-generated constructor stub
     BufferedImage originalImage = ImageIO.read(imageFile);
int imageW = originalImage.getWidth();
int imageH = originalImage.getHeight();
boolean firstScale = true;
scaledImages.add(originalImage);
while (imageW >= AVG_SIZE && imageH >= AVG_SIZE) {
     if(firstScale && (imageW > 320 || imageH > 320)) {
          float factor = (float) imageW / imageH;
          if(factor > 0) {
          imageW = 320;
          imageH = (int) (factor * imageW);
          else {
               imageH = 320;
               imageW = (int) (factor * imageH);
     else {
          imageW >>= 1;
     imageH >>= 1;
BufferedImage scaledImage = new BufferedImage(imageW, imageH,
originalImage.getType());
Graphics2D g2d = scaledImage.createGraphics();
g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g2d.drawImage(originalImage, 0, 0, imageW, imageH, null);
g2d.dispose();
scaledImages.add(scaledImage);
* This method returns an image with the specified width. It finds
* the pre-scaled size with the closest/larger width and scales
* down from it, to provide a fast and high-quality scaled version
* at the requested size.
BufferedImage getImage(int width) {
for (BufferedImage scaledImage : scaledImages) {
int scaledW = scaledImage.getWidth();
// This is the one to scale from if:
// - the requested size is larger than this size
// - the requested size is between this size and
// the next size down
// - this is the smallest (last) size
if (scaledW < width || ((scaledW >> 1) < width) ||

return scaledImage;
// shouldn't get here
return null;
A loop will loop through a collection of files and pass them to the constructor of Thumbnails to create thumbnails and then set them as icon for JLabels that will be added to a JPanel, but it throws a java.lang.OutOfMemoryError at this line:
BufferedImage originalImage = ImageIO.read(imageFile);
even when there're only about 8 image files in the collection (total size 2,51MB).
I've seen other people's software that could load hundreds of photos in a matter of seconds! How do I suppose to do that? How to load mutiple images efficiently? Please help!! Thanks a lot!

Thanks everybody! I appreciate your help! I don't understand why but when I use a separate thread to do the job, that problem disappear. You were likely doing your image loading and thumnail creation on the Event Dispatching Thread. Among other things, this is the same thread that updates and paints your panels, frames, buttons, ect.. When a programer does something computationaly expensive on the event dispatching thread then the GUI becomes unresponsive until the computation is done.
Ideally what you want to do is load images and create thumnails on a seperate thread and update your GUI on the event dispatching thread. I supect that while you are finally doing the first item, you might now be violating the second item.
Whatever, the program seems to be pretty slow on start up 'cause it have to reload images everytime. I'm using Picasa and it can display those thumbnails almost instantly. I know that program is made by professionals. But I still want to know how.I took a look at this Picasa you mentioned. It's the photo manager from google right? You're right in that the thumnails display instantly when starting up. This is because Picasa is actually saving the thumnails, instead of creating them everytime the program starts up. It only creates the thumnails once (when you import a picture) and saves the thumnail data to " +*currentUser*+ /AppData/Local/Google/Picasa2/db3/" (at least on my computer --> Vista).
Also, if your looking for speed then for some inexplicable reason java.awt.Toolkit.getDefaultToolkit().createImage(...); is faster (sometimes much faster) than ImageIO.read(...). But there comes a price in dealing with Toolkit images. A toolkit image isn't ready for anything until it has been properly 'loaded' using one of several methods. Also, when you're done and ready for the image to be garbage collected then you need to call Image.flush() or you will eventually find yourself with an out of memory error (BufferedImages don't have this problem). Lastly, Toolkit.createImage(...) can only read image files that the older versions of java supported (jpg, png, gif, bmp) .
And, another question (or maybe I should post it in a different thread?), I can't display all thumbnails using a JPanel because it has a constant height unless I explicitly set it with setPreferredSize. Even when put in a JScrollPane, the height doesn't change so the scrollbar doesn't appear. Anyone know how to auto grow or shrink a JPanel vertically? Or I have to calculate the preferred height by myself?Are you drawing the thumnails directly on the JPanel? If so then you will indeed need to dynamically set the preferred size of the component.
If not, then presumebly your wrapping the thumnails in something like a JLabel or JButton and adding that to the panel. If so, what is the layout manager you're using for the panel?

How to check SSO user from database?

Hi:
I've posted this topic in Forms forum:
How to check SSO user from database?
then as I've been told, it's better to post it here, so ...... here is the question:
I'm writing a "before delete trigger" to insert into log table before delete. Is there a way that I know from database the current SSO user when SSO users share one database user?
Just like in Oracle Application Express there is v('APP_USER') to know the current user.
Saad,

End users are manipulating data through Oracle Forms(and SSO through portal) and the thing I need is to trace the SSO username from database without modifying forms, I mean purely from database taking into consideration that SSO users are sharing one database user. Is it possible?
Saad,

How to load a image after getting it with a file chooser?

I'm still starting with JavaFX, and I simply would like to know how to load the image (e.g. png or jpg) that I selected using a FileChooser in the user interface. I can access the file normally within the code, but I'm still lost about how to load it appropriately. Every time I select a new image using the FileChooser, I should discard the previous one and consider the new one. My code is shown below:
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.shape.Rectangle;
import javafx.scene.paint.Color;
import javafx.scene.layout.HBox;

                    Button {
                        text: "Open"
                        action: function() {
                            if (JFileChooser.APPROVE_OPTION == chooser.showOpenDialog(null)) {
                                var imageFile = chooser.getSelectedFile();
                                println("{imageFile.getCanonicalFile()}");
                                image = Image{
                                    width: 640
                                    url:imageFile.getAbsolutePath()
            // Image area
            Rectangle {
                x: 10
                y: 10
                width: 640
                height: 480
                fill: Color.WHITE
            ImageView {
                x: 10
                y: 10
                image: bind image
}Thank you in advance for any suggestion to make it work. :)

As its name implies, the url param expect... an URL, not a file path!
So, use {color:#8000FF}url: imageFile.toURI().toURL(){color} instead.

How to load the data from informatica into bw & how to report the data

Hi friends,
how to load the data from informatica into bw & how to report the data
using cognos.(i.e how to access the data in sap bw using cognos 8 BI suite).
Thanks,
madhu.

Inorder to report BW data into Cognos you can extract data from using Open Hub to the DB table from which Cognos reads.
For BW informatic integration refer following docs:
