Oracle BLOB Display an image in Web Form

I have an Oracle database that stores image data. The data type of this image column is BLOB. I created a Window application using Visual C#, Oracle Provider for OLE DB to display the images on the Window forms. The mechanism to retrieve the data from Oracle database from client is to call an Oracle stored procedure that returns BLOB type. Now I want to convert it into Web application. I have difficulty to find
(1) Appropriate web control
(2) A way to bind OracleLOB object to this web control so the image can be displayed.
I am aware of the fact that in ASP .NET you can use ImageUrl property of an Image object to link a file stored in a particular URL.
Your help is very much appreciated.

Hi ,

Can you guys send some FMB examples on [email protected]
Please reply as sson as possible because we got stuck up here.

How to Display an Image on my FORM

Good Day!
I would like to ask some help from you guys with my problem on how to display an image on my form. I would like to display my uploaded image on my form but instead of an image, the get_blob_file is showing. By the way, I'm using Apex 4.1
I downloaded the Order Entry Sample Application and followed the Page 6, the Product Details. I even made snapshots of each details from Page Rendering to Page Processing in order not to miss a thing.
At the moment, I was able to upload or store the image on my created Oracle table and also able to retrieve it on the Download Link Text with Content Disposition value of Inline, provided by APEX Settings. If I invoke the Download link beside the file browser, a page with the image will be shown, below is the address:
http://127.0.0.1:8080/apex/apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6&p_content_disposition=inline
However, instead of showing the image on a region, below is the one showing on my Form:
<img src="apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6" />
As you can see the parameter values are the same but I know I missed something that's why I'm here :)
I would highly appreciate all the help you can provide and many thanks in advance.
I tried to change gear by making an html region of type PL/SQL (anonymous block) and a procedure but still no image :(
Below are the scripts.

htp.p( '<img src="my_image_display?p_image_id='||NVL(rec.empid,0)||'" height="'||100||'"/>' );
else
htp.p( 'No Image ');
END IF;
htp.p( ' ');
end loop;
end;
PROCEDURE
create or replace PROCEDURE my_image_display( p_image_id IN NUMBER)
AS
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);

BEGIN
SELECT MIME_TYPE, PHOTO_BLOB_CONTENT, PHOTO_FILENAME,DBMS_LOB.GETLENGTH(photo_blob_content)
INTO l_mime,lob_loc,l_file_name,l_length
FROM wsemployee
WHERE empid = p_image_id;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(l_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || l_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(l_file_name,instr(l_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
END my_image_display;

there's no way to "enable" it - sorry

Displaying icons in 10g web forms

Hi,
I was wondering if there is anyway I could use my jar file to display my images in my form. I created a jar file with images and I want to use them for my forms. The problem is other developers are using their own images from certain directories. In the registry.dat file they have a directory default.icons.iconpath=/icons/ already in place and in the .cfg file they have imageBase=DocumentBase. In my configuration for my form i put in imagebase=codebase but it seems that the other entry overrides mine because the images do not appear.Is there any way I could use my jar file to view my images without changing what other developers are using or would I have to put them in the directory with all the other ones.
thanks
Richie

Hi,
I've tried putting the jar file in the directory it mentions in the registry.dat file but that still does not work. I've also tried leaving the parameter in the .dat file blank and setting my imagebase=codebase and i am able to see the icons. My problem is that other developers are already using it using the documentbase and setting the .dat to a specific folder. I just thought there might be a way to read my jar file without interfering with the way the others are displaying their images. Its easier to have all my icons in a jar file then putting them all in a directory.
thanks
Richie

Displaying an image in a form

hi,
i am trying to display an image in a form. The code worked fine in j2me emulator, but when i converted the program to a jar and ran the same program in my mobile phone.
i get an exception in Image.createImage(.. method
and exception value is just null.
i know the image is not found in the specified location. but the image is there in the jar file.
how do i solve this issue?
thanks in advance.

Its definitly the heap size image, it can be case that image size is very large, u just try by optimizing the image and decreasing the size of image,
or
the image size(widht*height) is larger than actual phone screen
try with small image(small width*height) you will come to know the problem

Oracle Blob Display Error

Environment : Using Oracle Forms 6i (Currently on Patch 6.0.8.16) and Oracle
10g.
Problem : Error “Ora-00932 Inconsistent Data Types” when displaying a
blob from a database table using Oracle 10g.
Problem Description :
Currently in the existing application we have Oracle Forms 6i with Oracle
database version 8i.
There are no errors while displaying a blob (image) from the database table on my Oracle form. Upgraded to Oracle 10g but with the existing version of Oracle Forms we cannot display the blob in the Forms.If I remove the blob display from the form everything else on the form works fine.
Tried to update the Oracle Forms to version 6.0.8.16 using Patch 7 but it did not resolve the problem.
Tried to go through the bug fixes in the recent Forms version upgrade released by Oracle but did not see anything related to problem with blob display using Oracle 10g.
Did anyone else in the group faced the same problem?
What patch level resolved the problem?
Any ideas?
thanks and regards.

for where you store the image you can store it in the database table in the blob column such as. for the report layaut containing image take the following:
- in the report layaut you can create a report selecting a table that containing the blob column.
- in the report layaut, modify the property of the item that present the database blob column to image.

Try this (for MIDP 2.0)

Found this somewhere on the web long back.
Not tested, never really had to use blob
create table demo
( id int primary key,
theBlob blob
create or replace directory my_files as '/export/home/tkyte/public_html';
declare
l_blob blob;
l_bfile bfile;
begin
insert into demo values ( 1, empty_blob() )
returning theBlob into l_blob;
l_bfile := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen( l_bfile );
dbms_lob.loadfromfile( l_blob, l_bfile,
dbms_lob.getlength( l_bfile ) );
dbms_lob.fileclose( l_bfile );
end;
Now here is the package that can retrieve the pdf (or anything for that
matter. Just keep adding procedures that are named after the file type like
.doc, .pdf, .xls and so on. Some browsers really want the extension in the URL
to be "correct")
create or replace package image_get

Dynamic Text to be displayed as Image in Adobe Forms

Hi ,
I have a requirment to display dynamic text in the image format in the Adobe Form.
I have tried using the Image field instead of text field.But could not solve the problem.
kindly help me.
Thanks.

Hello,
if you send a text into a text field to the print form, it looks like a paper print, you cannot tell where there is a picture and where is the text. So you don´t care about the image/ text problem. If you need to make difference between two for the user, you can put the text (your image) into a rectangle, use a background or anything like this.
Why would the image make any difference?

But here the problem is when i executed this application i am able to see the VORNA and NACHN fields in ADOBE Form. But the employee photo is not appearing in adobe form.
Here employee photo i amretreving from archive link.
Even i set the Imagefield property URL in Adobe forms. i.e $record.IM_PHOTO.
Any solutions regarding this...
Regards,
Shankar.

Hi Shankar,
according to the sap documentation (inserting a graphic), I could imagine the following problems
1.) image file type is not supported (-> "see the online help in Adobe LiveCycle Designer under Defining Object Properties ® Image Fields ® About Image Fields" )
when you use "Graphic Reference"
2.) url could not be accessed.(-> "This means that you may have to configure appropriate access rights for Adobe Document Services (ADS)" ).
Maybe this will help you finding the problem.

Andreas

Safari Not Displaying All Images On Web Page

When I look at a web page in Safari on my iPhone 3GS, not all of the images on the page load. Instead, I see little blue squares with question marks in them. However, if I look at the same web page on an iPhone 4, the images DO load. Why is this happening?
Here are two screenshots to prove my point:

Displaying .ICO images in web browser

I have a need to display .ICO icon images within the browser. I'm finding that in MSIE they don't always work and in Firefox they display but they are very blurred. I'm wondering if anybody is aware of anything built into CF that might fix this problem? Possibly a flash component?
CF never ceases to amaze me, it always has a tag or component for every issue, but this one might be a problem!
Thanks
Mark

Yeah, since CF is a server technology and "I have a need to display .ICO icon images within the browser." kind of indicates that you are dealing with a client issue.
I am fairly confidant that the <cfimage...> tag is not going to do anything with the .ico format. At least I have never heard about it doing so. It is possible that there is java code out there that could do something with the ico format that will make it work better. If so, it should be pretty easy to inovke the java from within your CFML.

Display Image in a Form

Hey guys,
Had a question regarding displaying an image in a form. In the page, User enters all the details in the form and should be able to upload an image file
and also display a small size of the image uploaded in the same page.
Thank you for your help, really appreciate it
Jesh

Roel,
I have tried this example, but when I want to resize the image with the help of the link given at the end
Note: To modify the display attributes of the image (i.e. to make it smaller), you need to use the programmic way of including images. See the documentation at (http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10499/api.htm#CHDICGDA)
this link to modify the image doesnt work, it says Error Page.
Any Suggestions ? ? ?
Thank You
Jesh
