How to load and retrieve images from Portal!!!

Dear all,
I've designed a table with an ordsys.ordimage field for images. BIG MISTAKE, because there is no possibility to upload images from a form. I'd like to change it into a BLOB field but an error arises:
"You cannot modify the column definition for types CLOB, NCLOB, BFILE, BLOBand Intermedia Object types(ORDSYS.ORDIMAGE, ORDSYS.ORDAUDIO, ORDSYS.ORDVIDEO). (WWV-17079)"
Could I change it anyhow in order not to build a new table? I have a lot of forms referring to that table and I should change these forms too....(and we know it is pretty difficult)...
I would appreciate any help.
Tomas

Tomas,
Do you have any active constraints on that specific row? If the row is accessed by other forms (tables etc) you would need to disable them (for example foreign key constraints) and update the row (or remove and re-add it).

Hi Joakins,
I think Lloyd has a point here in that all I see there which is really database related is a connection string.
Maybe your question is more general though and you're just asking how to work with a database as a general principle.
Personally, I like entity framework and would recommend that.
You can read a shed load of stuff about it.

With WPF almost every dev uses MVVM and I'm no exception.
You may find this interesting:

It's complaining about this SQL in your code:create database if not exists imagedatabaseThat doesn't exactly look right to me. And perhaps "database" is a reserved word and can't be used in that position. At any rate I would recommend you create your database and tables in some other way before you write Java code to use them. Does Derby have a command-line interface or a GUI manager program? Use them if they exist to set up your tables.

How to copy and paste images from Internet to keynote on iPad?

I want to make presentations on the go using Internet images and keynote. How can I get images from websites copied into my photo album, as that seems to be the only way you can add a image in keynote. Is there legal problems involved in it? Because I can do it no problem using my desktop etc.
Thanks,
Dave

Click and drag is your friend!
This thread probably belongs in the safari area, but anyway:
If you click and hold, there should be a cursor that appears with a file. Then, simply drag it to your desktop where the file will appear.
Or:
Right-click (control-click) the picture and there should be a 'save image' or 'save image as' option. Select that, then save it!
Afterwards, simply find the file in your screen saver options in system preferences, and then select it.
Good Luck!

How to insert and view images from oracle using jsf

Can anyone please give me some code example or link of article explaining that how can i insert and view images to/from oracle using jsf?
Thanks in advance.

You mean you want to view image data stored in the database, right?
Create a servlet that streams the image data to the response (setting the appropriate content-type), then reference this servlet in your img tag. Here is an example:
http://balusc.blogspot.com/2007/04/imageservlet.html
Storage is something different. What exactly don't you understand there? Perhaps you want a file upload component?

Jar Loading and Retrieving Classes

How can I load and retrieve classes from a jar file?

I still do not know what you mean by "retrieve".
Are you trying to read bytecode for a class from the jar using util.jar.*,
or are you trying to get the class object for a class in a jar,
or are you trying to create an instance of a class from a jar,
etc.
What exactly do you mean by "retrieve" a class?

How the store and retrieval in ServletContext will happen??

Hello Sir,
I am developing a chat application thats in Swing & servlets Now I am able to authenticate user and I am using ArrayList to maintain the names of the user globally my storing it in ServletContext
How to store and retrieve ArrayList from Servletcontext
And another thing is that we are having personal chat(1-to-1) also. But how to use the thread model is not known to us as we have not faced such a situation before
So if you could suggest some example code or snippets ot certain links then it would be of great help to us
Thanks
Regards
Monarch

Hello
thanks for your reply. Actually we are doing the same thing that u have mentioned in your reply.
The thing we are trying to do is that when a user is logged in the particular servlet which is responsible for the authentiacation of the user will authenticate the user an then calls method in the Chatter class which is outside the servlet
The Chatter class declares two mwthods addChatter() and getChatter()
I am managing the currently logged users in Arraylist using this two mehtods above
When the first user logs in his entry gets stored at the first position in the arraylist but when other user logs in then his entry overrites the entry of the first user instead of getting stored in the next position.
The arraylist gets initialized when second user logs in. to overcome this problem i want to store the arraylist into the ServletContext so it will be unique for the whole application and will not get initialized
So I want to know the process of storing and retrieving the arraylist fro the context
Hope ull understand me and reply me
Thanks
Regards
Monarch
