Getting image stored in database !!

Hey !!
I'm really trying to solve so much problems i'm having with javafx !!
So, like the title may suggest, i'm having problems as to get image from the database !!
Everything seems fine but it tells me that there is "Exception while runing Application"
here is the code !!
@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.
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.
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.
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.

    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();
    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.

  • How to get images dynamically from database without file paths in the table field

    I have a MS-Access database. I am working with ASP.NET. In the database there is product table in which I have "CodeNo" as a field which is a text field, and the product codes like "SM-R-2035". I also have another field "Image" which is also a text field and which have a file path in it corresponding to the particular product Image (e.g. Images\Products\SM-R-2035.jpg). So far every thing is ok. I have to update this site very frequently and lots of images are added each and every time. Its a tedious work to type the paths and file name every time and it also take a lot of time.
    What I am asking is : Is it possible to get images from a specific folder at runtime which is referenced by the "code no" itself and not the file path from the database. (Say at run time the "code no" is referenced from the database and the corresponding image is loaded dynamically from the specified folder). In other word I want to avoid the tedious work of typing.
    Can any one help with this issue. Any other simple suggestions are welcome.

    All you need to do is simple concatenation to obtain the path for the image file.  You didn't mention whether you are using VB.Net, C# or some other language to do your coding.
    If the code in your database is SM-R-2035, the file name is SM-R-2035.jpg and the path to the images foilder is Images\Products\SM-R-2035.jpg, Conceptually here is what you need to do:
    dim code_var
    dim path_var
    code_var = the code you obtain from your relevant field in the database
    path_var = "Images\Products\" & code_var & ".jpg"
    Now path_var is what you would call to obtain the image from your images folder.

  • 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 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?

    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().
