Problem Populating Image Item From Database

Hi All,
I am using Oracle 9i & Forms 6i on Windows platform & working in client/server model. I created a form in which, I am reading an image file from the file system & then saving it into the database. In the Databse, i created the column as BLOB. But, when I query, this does not retrive the saved image in Image Item. But image is actually saved. When I tried, changing the database column to LONG RAW, it is working. I mean its reading the image in the image item from the database.
Can anyone pls tell me, is there any problem like this, as we can retrive from LONG RAW but not from BLOB, or I am missin something here.
Regards

Hi,
I use Forms 6i to save and retrieve image in BLOB column without problems.
Some weeks ago, my column was long raw and I update it without problems. Nothing to do in Forms and juste modifiy query and recompile in Reports.

Populating Image Item from 9i Database

Hi All,
I could store images into 9i database using Forms 6i Application. But I could not populate the stored images using Forms 6i application.
I appreciate very much for any help.
Thanks in Advance,
Umasankar.

Hi John,
Sorry for not explaining the problem completely.
Here is the details.
We are using Forms 6i and Oracle 8i. We are also planning to upgrade the database to 9i. I have application developed in Forms 6i. Using that application to connect 9i database, I could store images (from client system) into the 9i database (Using read_image_file). When I execute the query from Forms 6i application, I could not see the image from database. I was working OK with images on Oracle 8i database.
Thanks for your help.

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..

Swing Applet in JSP: problem with fetching data from database

i am facing a problem while fetching data from database using Swing Applet plugged in a JSP page.

}//end of initGUI()
private Vector getDBDatum() {

in index.jsp page i have included the following code for calling this applet:
<jsp:plugin type="applet" code="NewJApplet.class" codebase="applets"

</jsp:plugin>
if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!
i signed the applet as follows :
grant {

Bean to load image item from URL?

Can someone point me to a bean that will allow the loading of an image item from a URL?
Cheers,

Here is the material:
<p>
the screen shot is here : http://sheikyerbouti.developpez.com/forms-pjc-bean/handleimage/getimage.png</p>
<p>Get the jar file and the form module sample (9.0.2)</p>
Notice that you could also download the image with the File_Transfert.URL_To_Client() Webutil function then load it with the Client_Read_Image_File() built-in.

Populating menu items from the database...is it possible?

hi
using :forms 10g
we have a requirement in forms where we need to populate the menu items from the database.first we used hiearchial tree where it was possible.but since the requirement changed i am not sure that whether the menu items can be populated by data from the database...will be glad if someone could throw some light on this issue...
thanks

You could always do it but would need to put a fix limit on the number of menu items.
For example you could create a set of menu items at design time with the visible property set to False.
While reading the database, you then set them to True while setting the label to whatever you require.
But it all depends also on what you want your menu items to do when selected.

Problem while storing items from trailing list to database

hi all,
can anyone help me out. i have scenario where i have to store items from trailing list into database. suppose if there are 3 items in the list, 3 rows should be inserted into database with all the remaining fields same like
A ,1 , c
A, 2, c
A , 3, c where 1,2,3 are items from trailing list. Am iterating the loop.
What am doing is before saving am checking for duplicates i.e are there any records with the same combination. If yes am doing nothing else am committing the changes..
As am not doing anything if any duplicte record is present, the changes made to the fields persists and once if any commit happens all the values are getting saved. which is voilating my condition..
Thanks

hi nickelb,
i had returned Object.class in the getColumnClass() method. But then i
got NullPointerException at getRowCount() method. i could understand that the
main problem is in data[][] object. In all the methods its returning null values as it is so declared outside the construtor. But if i declare the object inside the constructor, then the methods could not recognize the object. it seems i cant do the either ways. hope u understood the problem.
thanx

Show image item from table into form's item.

Hi Friends,
My problem is:
I have 1 table with 2 cols:
eid number
e_pict blob.
I created a form (block based on this table). I'm able to show any valid image file stored in disk into e_pict (declared as image item) using the built_in READ_IMAGE_FILE. and also able to save it in the table test. But if I want to do the reverse process I mean retrieve the image from table's field to the image item of form, it creates problem. I even cannot compile the post_text_item trigger of eid:
select e_pict into :test.e_pict
from test
where rtrim(eid)=rtrim(:eid);
It is giving error:

Issues with Image rendering from Database

Maestros,
I have an issue here that I working but can hardly find a plausible solution and would like some help from the community. I'll do my best to explain the my issue in detail that way those of you who are savvy in this domain can jump on it right away.
I am in the process of implementing a shopping grid where products are shown as items on the grid. Each grid contains a custom product tag that contains a product image thumbnail, the description and price. All picture images are stored in a postgres sql database as byte arrays. I retrieve and rendered them on the product grid using a servlet that calls my product service.
The problem I am having is that when products are rendered not all the images are rendered even though they are present. One a refresh is done, some of the ones that previously did not render on renders and some that did go missing. I am using jsf and it looks like the application reaches the render response phase before the images are completely retrieved. I am also implement hibernate ehcache to see if that can help solve the problem, to no avail.
Is my approach the right approach? I know some of you would want to ask why I save images in a database and if you really want to know, the reason is because products are loaded dynamically and one product can have as many images as the e-shop manager wants. If please have another way to solve this problem please feel free to let me know. I am sure there is a better way of retrieving those images and render them without any issues and if you have done anything like that before feel free to send me some directions.
Thanks

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

Problem using Image Processor from Bridge

I have been using the Image Processor to process photos from Bridge for quite some time. However, I recently received an error message when I try to initiate Image Processor from Bridge and I have not been able to find any help topics that address my problem: I select images in Bridge to process, then click "Tools>Photoshop>Image Processor". Photoshop opens and the familiar Image Processor dialog box opens. Item 1 in the dialog box says "Process files from Bridge only" and has the number of files I have selected in parenteses. I select the file type and other settings in #3, and preferences in #4. When I click "Run", I get an error message window that says: "Script Alert. There were no source files that could be opened by Photoshop". The Image Processor works if I open the files in Photoshop first, then run it by selecting "File>Scripts>Image Processor" and tell it to process all open files.
Would someone be able to help me with this problem?
Thanks, Larry

Usually when it worked before and not now, and you have added no new software or hardware I recommend resetting the preferences. Hold down the Ctrl key and click on the Bridge icon to start. You should get a reset window with 3 options.
