Ordimage in ADF11g

Hi,
I have worked on BLOB image not shows in JSP page!! image retrival and currently I need to help how to view ordimage in my jspx page.
If anyone had compiled such program can you please give me a reference that how can I do that by ADF11g.
Note that I had created ADFbusiness components by ORDIMAGE table now need to show this image.
I had found a guideline but here not fully described about servlet implementation.
As seen in oracle site that ORDIMAGE supports in ADF11g but not found such solution.
I will be glad if any one can help me
Thanks
zakir

How to build a report on a table containing ORDSYS.ORDIMAGE type?

Hi
I build a table with a column of type ORDSYS.ORDIMAGE then I
build a form using wizard and populate the table by uploading
intermedia type and I can make query on that form and see the
image. But when I build a report using wizard, the report result
shows image data as it is in text format.
Am I doing something wrong or there is another way to make
report on ORDSYS.ORDIMAGE column type.
Thanks.
bye

This could be because, you might have the display type as text
instead of html for this column.
Could you pls verify this by selecting as html and try running
the report. If it still not working then pls post your Portal
Version so that we can verify it out here. Presently, it is
working fine for me.
Thanx,
chetan.

How can I display some OrdImages using a Applet in html or Jsp?

hi
I want to use a applet to display some images retrieved from intermedia OrdImage Object.
Now ,I know that a applet can display some image objects or some images with their own filepaths. But we can get ordimag objects from Oracle database.And we can image data or image properties by ordimage java mathod. It is in html/Jsp environment. So how can I transform from ordimage to applet?? I appreciate someone who can help me!
Bill

Do you mean applet or Servlet?
An Applet is java code that is downloaded over the web and runs in a web browser environment. Is this what you are doing?
I suspect you are really talking about servlet/JSP environments, and the ability to include images from the database in a web page.
In either case (applet or servlet), you want to be able to access images via a URL. For a Servlet/JSP/web page, this URL will be specified in a HTML <IMG> tag with a key as a parameter to the image you wish to view. Images are not in-line downloaded in a web page. They are access after the HTML is loaded, and are accessed with URLs, sometimes relative URLs rather than fully specified URLs.
To deliver images to the web from the database using the PL/SQL gateway and iAS, where the procedures are generated by a wizard, see:
http://otn.oracle.com/software/products/intermedia/htdocs/descriptions/imedia_code_wizard.html
You can create a simple servlet (JSPs can not deliver binary data) that delivers database images using java classes. See:
http://otn.oracle.com/software/products/intermedia/htdocs/descriptions/servlets_jsp.html
http://otn.oracle.com/sample_code/products/intermedia/htdocs/intermedia_servlet_jsp_samples/imedia_servlet_jsp_readme.htm
for a sample.

Ordimage performances big issue, please help

Hi, we are developing a visual retrieval application based on Intermedia.
The Database is Oracle 10g (10.1.0.4)
The Database is a RAC(Real Application Cluster) running on 2 Servers
The storage is a 2TB SAN
Each server is a quad-CPU (Itanium 2, 3GHz) with 8GB of ram each, the OS is Windows 2003 Server 64-bit Edition
one table of the db contains the ordimagesignature objects, we created a tablespace for the table itself and 2 other tablespace, one for the ordsignature filter and one for the ordsignature index.
This is the creation script for the index:
CREATE INDEX APP_IMG_SIGNIDX ON APP_IMG
(SIGNATURE)
INDEXTYPE IS ORDSYS.ORDIMAGEINDEX
PARAMETERS('ORDImage_Filter_Tablespace=TPC00F,ORDImage_Index_Tablespace= TPC00I');
TPC00F and TPC00I are 1GB each.
the tablespaces TPC00F and TPC00I are stored in the SAN and are dedicated only to ordimage data.
The table contains almost 300K rows.
Running a query like this (and no other activities on the server):
SELECT a.id_img, ORDSYS.imgscore (123)
FROM app_img a, app_img b
WHERE ORDSYS.imgsimilar (a.signature, b.signature, 'color="0.20" texture="0.80"', 5, 123) = 1
AND b.id_img = 2377165
ORDER BY ORDSYS.imgscore (123) ASC;
Can take from 3 to 7 minutes, depending on the ordimage parameters I choose.
This is obviously an unacceptable time for the hardware we have. Monitoring the performances of the machine during the execution of the query, shows that the CPU is almost idle while the IO queue is almost at 90% for all the running time of the query. We also tried altering the table with the command:
alter table app_img parallel (Degree 8);
but the execution time is the same.
ANY help would be very well accepted, thank you in advance.
Best Regards, Stefano

Have You still problem with the performance ?
I'm facing the same performance problems, i'm just testing a small amount of images from a big database. I have loaded (only) 5500 images into table, and generated signatures for them.
i have created a ORDSYS.ORDImageIndex on the signature, and analyzed that to.
After loaded > 2000 images the performance going down, and with (only) 5500 images
i get time on queries with IMGSimilar between 20 - 30 sec. . . .
ps, the total amount of images in the database is over 5 millions, bu tonly 5500 in table img_ordimage (so far)...

ORDImage in APEX 4.0.1 classic report

Hi
I can successfully show BLOB images in a report but I'm stuck when I switch to ORDImage.
I've been playing around with the Number/Date Format Column Attributes and borrowing from the BLOB version, have come up with
IMAGE:ORDIMAGE_IMAGES:THUMBNAIL:IMAGE_ID
However, I'm getting an error - ORA-06502: PL/SQL: numeric or value error: character to number conversion error
I guess it's the thumbnail which is causing the problem as this is the ORDImage column in the ordimage_images table
I've tried THUMBNAIL.GETCONTENT() and THUMBNAIL.CONTENT to no avail in attempt to get the BLOB data out of ORDImage
Any ideas?

Creating a new OrdImage in Java

I want to manipulate and validate an incoming OrdImage object before adding a record for it in the database. Specifically, I want to do a hash on the file and check for duplicates.
The few examples I've seen fetch an existing row from the database that already has an initialized OrdImage, but I'd rather do something like this:
OrdImage tempImage = new OrdImage(); // not able to do this
uploadPhoto.loadImage(tempImage);
Is there some code showing how to do this?
Alternately, is there a Java example that shows how to generically upload a file as a blob, and then push it into a new record that uses OrdImage?
Thanks!
Mike

Hi,
I am thinking you want to create the hash after putting it in the database because you are getting the image from HTTP? You could check the hash before insertion into the database, if you want it in the database before checking the hash, and you find a duplicate, you could simply roll back the transaction... This should not be a common case, so overhead should not be onerous.
I don't understand why you would want to upload a file into a simple blob before putting the blob in the intermedia object. We have examples, and utility classes for inserting images into interMedia.
See: http://www.oracle.com/technology/sample_code/products/intermedia/index.html

How to populate a table with ORDSYS.ORDImage item by BLOB item?

Hi, I have a table, that contain blob column and another table with ORDSYS.ORDImage column and I would like to populate ORDSYS.ORDImage item in table by BLOB item, in which I have store some images?

You should be able to do something like (this is off the top of my head, so please excuse any compile errors...):
define
b blob;
i ordsys.ordimage;
begin
INSERT INTO ordsysImgs VALUES (1,ORDSYS.ORDImage.init());
select imgCol into i from ordsysImgs where ID = 1 for update;
select blobcol into b from blobImgTable;
i.source.localdata := b;
i.setlocal();
i.setproperties();
update imgcol set imgCol = i where ID = 1;
commit;
end;

Problem w/ image item using 9i BLOB field and InterMedia ORDImage Object

Hi,dear all,
I have a problem with image item in Form 6i. Oracle 9i is used as backend DB, and a table contains image data is created for testing:
create table image_test(
id number,
image blob
In Form 6i, there is no problem to create a block for inserting/updating the image record into the database. However, it can not be used to retrieve image (blob field), the image item remains empty after 'execute query', while the id field can be retrieved. When the same table is created in Oracle 8.1.7, and the exact same form can be used without any problem both in inserting and retrieval. It seems that the Oracle 9i does not use the same way to store BLOB column. Has anybody ever encountered this problem? How to retrieve image (BLOB) in Form 6i from Oracle 9i?
I tried to use interMedia ORDImage as the data type in Oracle 9i, that is,
create table image_test(
id number,
image ORDSYS.ORDImage
Same problem, the form can insert record with image, but when retrieving, nothing displayed. Anybody could help! Thanks in advance!

hi!
well working with oracle8i and form6i.
same problem..but i used (instead of blob or clob as datatype..) Long raw..
it can be saved as usual..i mean Commit..
and can be retrieved..using Execute_Query..its working fine..
well if anybody get any other solution..do inform..

Diplaying of ordsys.ordimage field in a Report based on Query

Hi,
I have a table with a ordsys.ordimage field, where I am uploading images. I created a custom report based on that table but I just cant seem to find a way to show images in it. Could anyone please tell me how to do this.
I tried using this
"portal30.wwv_user_utilities.get_intermedia('CP_IMAGE01','CP_IMAGE01','IMAGE',rowid) the_picture " but this does not help at all
Thanks!
vimpi

Hello Prajwal,
It is definely possible !!
If you have already created your query pls paste the same here so that I can help you otherwise. I will give you a general guidelines and you can take it from there..
Using the CASE Statement inside your SELECT you can achieve this.
SELECT T1.ItemCode AS 'Item No.', T1.ItemName AS 'Item Description',
CASE WHEN T1.QryGroup1 = 'N' THEN T0.Price ELSE 0 END 'List Price'
FROM [dbo].[ITM1] T0 INNER JOIN [dbo].[OITM] T1 ON T1.ItemCode = T0.ItemCode WHERE T0.PriceList = 1

How to show an ORDImage thumbnail without storing it ?

Hi,
I'm using Oracle 10g r2.
I need to show ORDImages (and BLOBs).
Here is my procedure that shows thumbnails :
create or replace procedure show_photo_thumbnail(v_id_photo in number, v_height in number, v_width in number) as
     obj ordsys.ordimage;
     obj2 ordsys.ordimage;
begin
     --obj2 := ordsys.ordimage.init();
     select phot_source into obj from photos where phot_id = v_id_photo;
     select phot_source into obj2 from photos where phot_id = v_id_photo for update;
     obj.processcopy('maxscale= '||v_width||' '||v_height, obj2);
     owa_util.mime_header(nvl(obj2.getmimetype(),'application/octet'), false );
     htp.p('content-length: ' || obj2.getcontentlength());
     htp.p('content-disposition: filename="' || obj2.source.srcname || '"');
     owa_util.http_header_close;
     wpg_docload.download_file(obj2.source.localdata);

end;It works, but if I call this function repeatedly (from our apex application), the image quality becomes less and less good, it seems it processes always the same image.
And for example if I call show_photo_thumbnail(1126, 150, 150) and then show_photo_thumbnail(1126, 500, 500), it seems the 500 x 500 image is processed from the 150 x 150 thumbnail so the quality is very poor.
I read the entire documentation and I really don't understand why.
By calling this other procedure we can see that the content stored stay unchanged :
procedure show_photo_infos(v_id_photo in number, v_height in number, v_width in number) as
     obj ordsys.ordimage;
     obj2 ordsys.ordimage;
begin
     select phot_source into obj from photos where phot_id = v_id_photo;
     select phot_source into obj2 from photos where phot_id = v_id_photo for update;
     obj.processcopy('maxscale= '||v_width||' '||v_height, obj2);
     dbms_output.put_line('obj : '||obj.getmimetype()||', '||obj.getcontentlength()||' bytes, '||obj.getwidth()||' x '||obj.getheight());
     dbms_output.put_line('obj2 : '||obj2.getmimetype()||', '||obj2.getcontentlength()||' bytes, '||obj2.getwidth()||' x '||obj2.getHeight());
end;
show_photo_infos(1126, 200, 200);
obj : image/jpeg, 79754 bytes, 572 x 504
obj2 : image/jpeg, 4635 bytes, 200 x 176Any help would be much appreciated.
Thanks.

It should work exactly the same for ORDimage and BLOBs, as ORDImage stores and updates the image content in a BLOB attribute.
The difference you are seeing might be because of which object you are reading. In the first example, obj2 was selected for update, but obj1 was not. So the local variable obj1 had the old data which was printed out, and this was different from the data in obj2, which had the changes that were updated in the table.
If you don't want to persist the updated image, then you can select for update, make changes as you are currently, but then rollback at the very end (after you download the content). Then the original image will be retained in the table and changes you made in this transaction will be discarded. The next time you run the procedure you will be operating on the original image.
I also notice you have a commit in the very first code snippet but not later. Depending on your logging settings that might be having an impact as well.

Problem with ordimage attribute in detail viewobject (a bug maybe?)

Hi
JDeveloper: 11.1.1.4
I have an ordimage attribute in a viewobject among other attributes but it doesnt show the image while it shows other attributes of the viewobject correctly. It throws java.lang.ArrayIndexOutOfBoundsException when executing the "row = rows[0];" instruction in oracle.ord.html.OrdPlayMediaServlet.renderContent() method. Apparently the main reason for this error is that the vo viewobject doesn't get populated correctly (it contains no rows at all) and so the "rows = vo.findByKey(mKey, 1); " doesn't return any rows.
Isn't this a bug? Is there any workaround to this?
P.S: When I use another instance of the same viewobject as a master viewobject works just fine. The error occours only when the viewobject is used as a detail viewobject.
Anyway, here is the exception:
]] Root cause of ServletException.

I have encountered the same problem.
JDeveloper 11.1.1.3
Did you come up with a work-around since September?

Displaying images from ORDSYS.ORDIMAGE columns

Does anyone know, if Oracle9i Reports can display images fetched from ORDIMAGE columns in the database? If so, could you give me a brief explanation how?
Thanks in advance!

Jacob,
As of now , it is not supported. It is under development for next release.
It currently supports images stored in DB as LOBs
Thanks

Weblogic Server issue in ADF11g

Hi All,
Im working in ADF11g . My .jspx used to work but suddenly it is giving the followng error inspite of correct url in the browser.
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
Can anyone help me in solving this issue.
Thanks,
User

Hi,
if this is with the integrated server in JDeveloper then check if you have hanging Java processes in the Windows Task Manager. If you are accessing bounded taskflows and this happens, make sure that the taskflow is accessible, or if you use some state token with it that the state token is valid
