Rendering BLOB images in JDEV 11.1.1.6

Hi Experts,
I know that we need to use servlet to render BLOB images in ADF 11.1.1.5.
But is there way in 11.1.1.6 where we can get it direclty in <af:image>?
Regards,
Ankit

No, there isn't any change to this. Using a servlet is still the best option.

Display BLOB (image) column in (interactive) report

Hi,
I have a field called "picture" in my table "details" which is of type BLOB. i also have a field for "MIMETYPE" and "filename"
i additionally have a "name" and "description" columns which i need to display along with the picture as columns in a report (preferably interactive).
i have also modified the BLOB display format as per
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
what i am missing is the correct query. if possible, i would like to control the size of the picture rendered within the report like say 40*50.
I have also referred to the thread
APEX 3.1 Display BLOB Image
But i don't know how to place the
dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT"
in my query.
The above also makes the report column as of type "number". is this expected?
Any help would be much appreciated.

You haven't actually said what the problem is?

Something like:
select
          name
        , description
        , dbms_lob.getlength(picture) picture
from
          details
if possible, i would like to control the size of the picture rendered within the report like say 40*50.For images close to this size it's easy to do this for declarative BLOB images in interactive reports using CSS. Add a style sheet with:
.apexir_WORKSHEET_DATA td[headers="PICTURE"] img {
display: block;
width: 40px;
border: 1px solid #999;
padding: 4px;
background: #f6f6f6;
}where the <tt>PICTURE</tt> value in the attribute selector is the table header ID of the image column. Setting only one dimension (in this case the width) scales the image with the correct aspect ratio. (The border, padding and background properties are just eye candy...)
However, scaling large images in the browser this way is a huge waste of bandwidth and produces poorer quality images than creating proper scaled down versions using image tools. For improved performance and image quality, and where you require image-specific scaling you can use the database ORDImage object to produce thumbnail and preview versions automatically, as described in this blog post.

BLOB Image in JSP

I have an image in my database saved as a BLOB dadat type.... I want to paint this image in my homepage with the tag <img..>, using a jsp page.... can anyone tell me how can i do it?
Thank you!

Hi,
U cannot do this directly thru JSP.
U will need to use a servlet for this and call the servlet in your <img> tag in your JSP.
Regards,
Moin
The code for servlet is as follows:
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
* This is a servlet which renders an Image stored as a blob in the database.
public class BlobImages extends HttpServlet{
/**Process the HTTP Get request*/
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException{
try{
//Calling the method getImage() to get the image from the database and rendering the same.
byte[] buffer =myDB.getImageData();
if(buffer != null){
response.getOutputStream().write(buffer,0,buffer.length);
} catch(Exception e){
Utilities.printStackTrace("BlobImages",e);
}//end of catch
}// end of method do GET
}// end of class
and the jsp tag will be as folows
<img src="http://localhost:7001/BlobImage">

How to view blob/image in uix?

Version: JDev 9.0.5.2
Goal: To view an image that is coming from a database table.
Set Up:
In the database: I have a database table with a blob data type. The blob data type contains a pointer to the image in a database directory.
In JDev.model: I have an Entity Object and View Object that contains the column attribute with a blob/blob domain data type.
Question: How do I build a uix page that allows me to pull in the blob (image)?
Thanks for the assistance.

Displaying BLOB image by using ADF Faces

Hi all,
I digged the forum but couldn't find any satisfied answer about displaying BLOB images by using ADF Faces.
I have insterted POJO object to Oracle database but couldn't find any way to display blob (in java byte [] ) data in POJO.
I have read the POJO object from database which contains two field; one of them is id field and other is BLOB data which holds GIF or JPG image and I want to display this image another page which contains also other fields / records ...
thanks for your answers

This thread at Sun : http://forum.java.sun.com/thread.jspa?threadID=513804&messageID=2445090
talks about two options for creating a graphicImage jsf tag. (img tag)
1. Make the img tag url refer to a servlet (instead of a static image file)
2. Embed the image into the tag as inline base64 encoded data.
2a. Use an <Object> tag with inline data.
1. Looks a bit complex for a simple problem.
2 and 2a don't work with some browsers.
- And I've not yet figured out how to hook into the ADF Faces table-rendering logic to get it to add my image column. My table binds to a collection DataControl, [which in turn retrieves from a findAllItems call on a session facade, which uses my domain model, and wraps up access to a TopLink pesistence layer]. The framework just ignores my byte[] attribute when creating the jsf table from the DataControl. All string, int etc. attributes get represented correctly in the jsf table output.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
     private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
          ServletOutputStream sout = response.getOutputStream();
          for(int n = 0; n < bytes.length; n++) {
               sout.write(bytes[n]);
          sout.flush();
          sout.close();
     }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

I need to display my Blob image in my report (and also on form page)

Scott,
I followed the APEX advanced tutorial for uploading and downloading files. I have created a form on a table and that table contains a column of datatype BLOB. Now I want to be able to display the (Blob) images that I have uploaded.
As I research the topic, I get the feeling that displaying the BLOB image can only be done in APEX 3.1 and up. Is this true? I have that version of APEX installed on my laptop and have successfully completed the "Defining and Viewing BLOB Data in Oracle Application Express 3.1" tutorial found here: http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm
But I could not do it on the company server that runs APEX 3.0
Even if I did get the approval to have the company APEX application upgraded to 3.1, there still is the issue of scaling the images so that they are not so large. I understand that there is a UTIL.APEX function "GET_BLOB_FILE_SRC" that would do this for me. I read the documentation at:
http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10499/api.htm#CHDICGDA
After reading it, I was still not clear as to how to use it correctly. Is there any documentation on how to implement this function in APEX?
I did find something that I was hoping would help me. The article is entitled "Show Blob of other table in APEX Form" by Dimitri Gielis can be found here: http://dgielis.blogspot.com/2008/07/show-blob-of-other-table-in-apex-form.html
I tried to import the file "blob_support.sql" application (on both APEX 3.0 and APEX 3.1 systems) but got errors. I'm not having very much luck here and would appreciate the help in pointing me in the correct direction.
Help!!
Thanks

Hello John,
Your information was helpful. I can now see my images in my form.
OK, now I would like to be able to call the image using a Region Source of type SQL instead of the HTML Expression. The reason for this is because I need to use logic to determine if the file is an image or not and to determine wether to show a thumbnail or just a link. I did find a "GET_BLOB_FILE_SRC" Function on the internet that suggests that I could do this but I need some help in making it work in my application.
Here it is as a Region Source of type SQL:
SELECT ID,
NAME,
CASE WHEN NVL(dbms_lob.getlength(document),0) = 0
THEN NULL
ELSE CASE WHEN attach_mimetype like 'image%'
THEN '<img
src="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'" />'
ELSE '<a
href="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'">Download</a>'
end
END new_img
FROM TEST_WITH_BLOB
If anyone can help me with this that would be appreciated.
Thanks

BLOB image in XML Publisher

Currently we are using 6i reports to generate XML output, which in turn is passed to XML publisher to generate documents.
I am trying to access a blob image from DB in 6i reports. How Can I pass this image to XML publisher.
Basically my doubt is:
How do I incorporate BLOB image from database into XML Publisher? What are the different approaches available?

Hey David, well, this isn't the unique solution for displaying images in XMLP. The other alternative (wich is my plan b) is to have this images in a path in the server. So, you can bring the name of your image (maybe, a signature) from the database; I have test that and works very well.
I'm trying to use an URL because the signatures are stored as BLOBs in the db and I was trying to re-create the file in the server, but it became a little complicated. So, in my case, I just have to resolve any of this issues and I'ld have my images in the reports.

In Report 6i, Blob image not showing

i save blob image file in database using Oracle Form 6i.
and now i create report to display image.
Select id, Foto
from table
Image field is created, then i changed format type as image.
Now the error displaying when i execute report is
rep 1818: Unable to read data in image format
and rep: -619 you can not run without a layout.
Please help me.

rep 1818: Unable to read data in image format
and rep: -619 you can not run without a layout.
this is the error

(( BLOB IMAGE *NOT* being saved ! ))

Hello,
I am new to APEX.
I am working with the SAMPLE APPLICATION
that comes with the free APEX.ORACLE.COM
account.
I am creating 2 pages similar to the
PRODUCTS report and the
PRODUCTS form.
(Page 3 and PAGE 6)
I am creating my own table
and my own pages.
I created my own table---
similar to the
DEMO_PRODUCT_INFO
table--which has all the PRODUCT
information in it.
This table looks like this:
http://mankindwins.com/__7700-2900-APEX-GLOBAL-201/850-500-SCREENSHOTS-FOR-POSTS-205/DEMO_PRODUCT_INFO__TABLE.gif
I used the APEX wizard to create a REPORT
on a table with a FORM.
I then replaced the source code wide
code similar to this:
select p.product_id,
p.product_name,
p.product_description,
p.category,
p.product_avail,
p.list_price,
p.product_id image
from demo_product_info p
That worked fine.
I then went into the
BLOB Download Format Mask
and I defined it to be something like this:
IMAGE:DEMO_PRODUCT_INFO:PRODUCT_IMAGE:PRODUCT_ID::MIMETYPE:FILENAME:IMAGE_LAST_UPDATE::inline:Download
This works fine.
It shows the images.
The problem is this:
When I try to create a NEW PRODUCT
the browse button is there,
I CAN upload a new image.
But then, when I hit the button
to CREATE the NEW PRODUCT---
it does **NOT SAVE** the
IMAGE
MIMETYPE
FILENAME
IMAGE_LAST_UPDATE
All the other information is saved---
( product name, category, etc.)
but NONE of the IMAGE INFO !
My question:
How do I get this information saved???
The BROWSE WORKS---
but the CREATE the NEW PRDOUCT
is NOT SAVING ANY OF THE IMAGE
INFO !
Why not?
Thanks for your help!
I really appreciate it!

Hello,
I found the answer!
I looked in the SAMPLE APPLICATION
PAGE 6
P6_PRODUCT_IMAGE
I looked at SETTINGS.
I put in the settings for the
blob image.
That made it work!
The values were saved!
YAY!

Hi here is solution,
later I will put a project for this solution, right now I am really busy with ADF implementation.
core changes is to solve my problem:
    byte[] buffer = new byte[image.getBufferSize()];
    int nread;
    vo.remove();
    while ((nread = is.read(buffer)) != -1) {
      os.write(buffer);
    }All code as below:
Servlet Code*
public void doGet(HttpServletRequest request,
                    HttpServletResponse response) throws ServletException,
                                                         IOException {
    String appModuleName =
      "his.model.ModuleAssetMgt";
    String appModuleConfig =
      "TempModuleAssetMgt";
String imgno = request.getParameter("imgno");
    if (imgno == null || imgno.equals(""))
      return;
    String voQuery =
      "select ITEM_IMAGE from MM_ITEMIMAGE where IMAGE_NO = '" + imgno + "'";
    String mimeType = "gif";
    ApplicationModule am =
      Configuration.createRootApplicationModule(appModuleName,
                                                appModuleConfig);
    am.clearVOCaches("TempView2", true);
    ViewObject vo = null;
    String s;
      vo = am.createViewObjectFromQueryStmt("TempView2", voQuery);
    // Run the query
    vo.executeQuery();
    // Get the result (only the first row is taken into account
    Row product = vo.first();
    BlobDomain image = null;
    // Check if a row has been found
    if (product != null) {
      // We assume the Blob to be the first a field
      image = (BlobDomain)product.getAttribute(0);
      // Check if there are more fields returned. If so, the second one
      // is considered to hold the mime type
      if (product.getAttributeCount() > 1) {
        mimeType = (String)product.getAttribute(1);
    } else {
      LOG.warn("No row found to get image from !!!");
      return;
    // Set the content-type. Only images are taken into account
    response.setContentType("image/" + mimeType);
    OutputStream os = response.getOutputStream();
    InputStream is = image.getInputStream();
    // copy blob to output
    byte[] buffer = new byte[image.getBufferSize()];
    int nread;
    vo.remove();
    while ((nread = is.read(buffer)) != -1) {
      os.write(buffer);
    is.close();
    os.close();
    // Release the appModule
Configuration.releaseRootApplicationModule(am, true);

Managing blob images using ADF and JSF or struts

Hello everyone. I am an ADF newbe and I am developing a web app. that has to manage (display, insert,update and delete) blob images from/to an oracle DB. I've seen the "howto" on image managing using intermedia and struts, but, for this new app I wanted to use JSF (something that is not mandatory) and, what is important is that the DB has already stored the images in blob format.
Can anybody point me in the right direction please??? Is there any howtos on this subject???
Thanks in advance.

System.out.println(<..../>....<>....</>).Assuming that you rather mean out.println() where out is the ServletOutputStream reference returned by HttpServletResponse#getOutputStream(), I can only agree with you. That's certainly not the way how JSP/Servlet code is to be written. The maintainability, extendability, reusability and testability would be far below the freezing point then. You need to write presentation logic in JSP files, not in Servlets and absolutely not in scriptlets inside a JSP.
When you need to write presentation logic which may change per request, use JSTL and EL for that. Again, not scriptlets. For business and controlling logic, use Servlets. For transfer of data, use javabeans (DTO's, VO's). For data access logic, use DAO classes which are to be interacted by servlets.
JSF removes the need for creating Servlets and using JSTL/EL in JSP files. You just have JSP pages with JSF tags for presentation and javabeans for the request values and backing beans for business logic.
When would one use JSF over the other two? When Struts2? When Shale?And you ask that in a JSF forum? At least my opinion is predictable :)
