Showing Image Stored In DataBase

Hello Friends,
I have images stored in MySQL database. In a blob field. In a desktop application i have used
blob b=rs.getBlob("Picture");
byte[] buf=b.getBytes((long)1,(int)b.length());
ImageIcon imgIcon= new ImageIcon(buf);
Image img=imgIcon.getImage();
Graphics g=image.getGraphics();
g.drawImage(img,0,0,320,240,image);
the thing worked fine. But now i have to show images over web. I am not able to uderstand that how to show images. As i m unable to get Graphics from any of the component.
Help Me,
Its urgent,
thanking u all

The common method to include binary information (image, PDF, document, etc) is to Base64 encode the file and store the resulting character string in the XML. It would be up to the receiving system to handle the encoded information in the XML.

@James D, i will come back bugging yu again to see how to use the stored images and display them inside the combobox and to render them ^^
I haven't well understand how well as to use the enum struc in which yu declared the composed <Image,String> type ^^

In any real application, it's a mistake to mix your presentation (user interface) code with your persistance (database access) code.
Why? You want maintainability, flexibility, and testability.
Maintainability:
Suppose you want to change the structure of your database. E.g. the database admin (which may be you, or someone else) determines that the database design you have is inefficient and needs to be changed. If your database code is scattered over the whole application, mixed in among your user interface code, tracking down what needs to be changed will be a nightmare. If all your database code is in a single class, or perhaps a set of classes in a single package, then the updates are localized and much easier to manage. Furthermore, you can build the new database access code on its own, test it out, and then when you are sure it works just switch your user interface code to use the new persistance layer instead of the old one. The same applies if you decide you're going to use a completely different technology to store the data; perhaps you want to use something like Hibernate instead of plain JDBC, or maybe you decide you want to make the data accessibile via a web service.
Flexibility:
What if you (or, more likely, your manager) decides they're going to change to a new user interface technology. Maybe they decide to switch to a web application (i.e. HTML-based) instead of a desktop application. You obviously need to rewrite the user interface code, but you should be able to keep all the database access code you've written. If your database access code is all jumbled up with the user interface code you're replacing, it's going to be way harder to reuse that code. If the two are separated out, you just build a new user interface in whatever new technology you're using, and access the same class(es) you used for your database access without touching them.
Testability:
This whole thread is actually a demo of how testability is much harder if you don't properly separate your code. You posted "getting image stored in database", thinking that was your problem. It wasn't; your problem was actually an error in the way you'd set up your JavaFX code. Because the two were completely mixed together, it was hard to know where the error was. The error you had was actually a really simple one; it would have been much easier to see if you had simpler, properly separated code; but because you didn't organize your code like that it took you days to figure out the problem. This was only a couple of dozen lines of code; imagine how this looks in a real application with hundreds or thousands of classes.
The point is that decisions about how to access your data (standalone database, web service, or EJB?; plain JDBC, JPA, Hibernate, etc?) , and decisions about the presentation technology (desktop or web? JavaFX or Swing?, or Servlets/JSPs, JSF, Swing MVC, or any of a huge number of frameworks) are completely independent. You should be in a position to change those decisions - to redesign aspects of the application - with the least amount of effort possible. Failing to properly design things will make this much harder, or likely completely impossible.
These are real concerns that affect every application that goes into production.
Even if you're just making a small application, it will benefit you to set things up correctly from the outset.

Show images stored in DB in browser

Is is mandatory to use intermidia for showing images stored in DB?
I mean,is it possible to use just PL/SQL to show images uploaded to Oracle 8i. If so, how? Does anyone could send me a sample code?
Thanks in advance and best regards.

I have Oracle 8.1.5 and I read that interMedia license is included in DB license.
In this case I am free to use interMedia.
Does interMedia comes with 8.1.5 also?
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by ymizuno():
You can store images as Blobs in the database, without using interMedia. However, if you store images as OrdImage using interMedia with attributes, you can get many advantages of it. interMedia comes with the Oracle database if you have Oracle 8.1.6. Are there any particular reasons why you do not want to use interMedia? <HR></BLOCKQUOTE>

Serving webpage with image stored in database

This may look long, but it's easy to understand--I'm just trying to give all the details you might want: In our servlet/JSP site, a user can generate a report that may or may not contain images. The servlet just sends the user to a regular HTML page. The HTML file and images it may have are stored in directories on the Tomcat server. But now we have a problem...
We're moving to 2 standalone Tomcat machines with a load balancer in front, and so now we want to move any of this stuff that was stored on the webserver into the database. If the HTML text for the report has not yet been generated for that day, I can see my web app going to the database to pull out that HTML, and if there are any images, it could pull those out of the database, but then...how does it get those to the user's web browser?
Currently, when this report loads in the browser, we do a sendRedirect to the file, and the URL displays the full path to the file (and in the HTML code, there is of course a relative link to the image file). But now, these are supposed to be pulled out of the database...are we going to have to pull them out of the database and then write them out to file on the webserver (since they might not exist on that webserver), or is there some other/better way to display them to the user?
Thanks...

You can create an Image Servlet that you use to stream the image streight from the db to the page. The URLs that you use in the HTML pages would point to this Servlet with a parameter identifying the image (or you could map the Servlet to *.gif for example). The servlet then sets the content type to the appropriate image format, retrieves the image from the DB as a Stream and copies it byte for byte to the response output stream.
If you search the forums you will probably find an example of how to do this.

How to access images stored in database using forms

i have created a table which stores images in bfile type
i would like to access the images along with other data
stored in forms.iam not able to get the image using select statement.could anyone tell me the format using which i would be able to access the image.

in my impression, Oracle's samples store the BFILE images off line though if I did not remember wrong.
If you can create a form type form using form wizard based on that image table, then you may execute query to view the image. But SELECT ... INTO will not work for LOBs on form.
If off line in file system, you may try to READ_IMAGE_FILE().

How to fetch images stored in database to reports

i have stored images in bfile type.i need to access the image.pls do inform me urgently.

Hi,
Follow the steps to access images using Reports.
1. create the sql query in datamodel editor.
2. Open property inspector for Bfile column
3. Set file format property to Image.
4. Goto Report's layout editor
5. Create field and required frames, set field's source to BFILE column name.
6. Now run the report

Help........Show image from database

Hi,
I am stuck at one point. I have to show image stored in the database on the browser. I am able to fetch the image and show it after storing it in one .gif file. But what I want it is : I don't want to store the fetched image in to a .gif file instead I would like to show the image on the fly after fetching it from the database.
The reason I need it this way is...If I store it as .gif before showing, after showing the file the file still will be present in the disk, which after sometime will go beyond the limit.
If at all it is not possible to show it on the fly, then I would like to know if there is any "SESSION ON END" kind of even available in Java so that I can clean up the image when user exits the browser!!!
Please reply as soon as possible.

For the first part of your question: If the image is the
only thing you are showing on the browser.. then
you can stream the data (I think I never tried with
gifs)
try {
     response.setContentType("image/gif");
     ServletOutputStream outf =
response.getOutputStream();
// Print the steamed image data to this
outf
outf.flush();
     } catch (Exception e){
          System.out.println("Exception Caught"+e.toString());
}

Display images stored in the database

I have images stored in the databse. I followed the steps provided in the oracle documentation. Now i want to retrive the image from the database into a java object that can be dislayed in , say, a JLabel. I am able to retrieve the image from the database into the OrdImage in the oracle.java.ord package and view the properties of the image. But unable to retrive the image as such to be displayed.
Thanking You

Size limit of access database with image files stored outside database

I have read 2GB limit on size of Access database. We are using Access 2013 database with fields that are data type attachment and storing attached images outside the database. Does the size of the folder that is holding these images count
in any way toward 2GB size limit?

Hi,
As far as I know, Access database limit size 2GB based on itself, not related to the folder size. Attachment data
type is similar to attaching files to e-mail messages. We need to control the Access database size is smaller then 2GB.
When a field is defined with the attachment data type, you can store one or more files for each record in it.
Attachments can dramatically increase the size of the database, but since the attached file is stored as a part of the dabatbase, you are not dependent on network drives being available as you would be if you inculded a hyperlink to the file. As a matter of
fact, feel free to backup the origainal file to other disk after you attach it to the database.

For best performance what's the size of an image to be stored in database?

Hi all,
can any one tell me..for best performance what's the size of an image to be stored in database?
is it <256kb or >256mb?
when i google we can store image as varbinary(max) and its limit upto 2GB..
Can anyone exlain it?
is it performance wise better..
thanx in advance..
lucky

Your question does not seem apparently meaningful. If you need to store a 5MB image in the database, you store a 5MB image, not a 200 KB image or a 200 MB image. Business needs always trumph performance.
Not surprisingly, the larger the image the more resources it takes to read and write it.
What is a meaningful question is whether you should use the FILESTREAM feature or not. The cut-off limit here is usually given as 1MB. That is, if your images typically exceeds 1MB you should use FILESTREAM and access the data through Win32
API. If your images are generally below this size, you should stick to regular T-SQL.

Showing image from database

Hi,
can anyone tell/give me an example/tutorial of how to retrieve the image from the database into forms? so i have a table names EMPLOYEES for example, and i added a clob type column, named "photo". in forms, when i show the informations for each person, i wanna already retrieve the image, somehow. how can i do this? a small example i think will be persuasive :)
Thanks!
