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.

I want to store and retrieve images from a oracle datrabase's BLOB type

Hi all
I am using WebLogic and Oracle 10g.I have to store images and retrieve them from a BLOB type.
Please help .

Store and Display Image from Database

Now that MySQL is working (woo hoo!) with JSC, I have a couple of questions for any experts out there...
1. How would I perform an image or other file upload from a browser?
2. How would I retrieve and display an image from a db on a jsp page?
Thanks for any help.

Craig, I think I have a simpler way to load an image on the page, although for the time being I'm not retrieving from a database, but from the file system. The problem is that I'm not getting the pages to load continuously with new images. At some point it apears that the session gets clogges and can not load new pictures. I'll try to include the page bean code just below. This time I'm not adding the "code" tags because I haven't being successful with that. If you have problems , please, contact me at [email protected].
The core of the code is in a couple of button_action methods.
If you need, I can give access to the http server where this is running.

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 load and retrieve images from Portal. URGENT

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).

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

How to store and retrieve chinese characters

Hi, I am facing some problem in storing and retrieving of chinese characters from oracle,9i .
This is the character i am trying to store into the database
èªå¨ææ¬¾æºç½ç»
while trying to retrieve it, it shows
èª?ææ¬¾æºç½?
^ ^
you can see the weird characters like ? at some places.
here is the sample code which i can using to store and retrieve data from the database
class testInsert
public static void main(String[] args)
try {
     DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
     Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@172.16.6.81:1521:JFPPTDB1", "citi_user", "citi_user");
     int employee_id = 12345;
String ename = "èªå¨ææ¬¾æºç½ç»";
     oracle.jdbc.OraclePreparedStatement pstmt = (oracle.jdbc.OraclePreparedStatement)conn.prepareStatement("INSERT INTO employees (employee_id, last_name) VALUES (?, ?)");
     pstmt.setFormOfUse(2, oracle.jdbc.OraclePreparedStatement.FORM_NCHAR);
     pstmt.setInt(1, employee_id);
     pstmt.setString(2, ename);
     pstmt.execute();
pstmt.close();
pstmt = (oracle.jdbc.OraclePreparedStatement)conn.prepareStatement("SELECT last_name, employee_id from employees");
ResultSet rset = pstmt.executeQuery();
          String name = "";
          while(rset.next())
               name = rset.getString(1);
     int id = rset.getInt(2);
          System.out.println("the name is :"+name);
catch (SQLException sqe)
          System.out.println("Java SQLException caught, error message="+sqe.getMessage());
and the table in oracle is
SQL> desc employees;
Name Null? Type
LAST_NAME NVARCHAR2(10)
EMPLOYEE_ID NUMBER
I am using classes12.zip for oracle,9i. Is there any database setting that i need to know to retrieve the chinese characters?.
I have been facing this problem for quite sometime and it makes my life tough. Please help me in solving this issue.
Thanks
PD

hi, can you retrieve the chinese character from your os? When it comes to the wild code of asian character, you should focus on the database/client character setting. you may ask more about it from your dba.
have a nice weekend!

Is creating a New Catalog for EACH shoot the way to go?   (not sure I like this idea)
Right now everything is in one(1) catalog ... and it's getting big ... BUT, this allows us to search , and group ... going way back.
Would be nice to be able to still do this easily, and with what we have already done.
With our one BIG Catalog ... not sure if two(2) can access this catalog over the Network at the same time?
Even though we never Edit the Same Folder or Files at the same time.
Or will that be a problem over a simple Win7 PRO network?
Thank you,
HG

Aloha Bob,
Saw your link. thank you.
At least I don't feel "alone" LOL
At this point ... I am looking for a "cluncky"   Work Around?
* I was thinking, Maybe making a copy of My Cataloge ...
Deleting ALL the Folders in LR ... except for the one's that will be worked by the Asst.
Then moving that file to the Asst. Computer.
* NEXT, pointing the Folder that they are working on ... across the Network to the Servers Files.
* After they work on it:
*** IS THERE A WAY ...
* To take that Cataloge ... and UPDATE my Main Cataloge.
THIS, is the STEP ... I don't know how to do.
Can someone Help me with this?
Step by Step, because I am clueless ....
Talking UPDATE of everything worked on ... including   Virtual copys, and CROPS.
Thank you,

Retrieving image from database in form 6i

hello all
i'm working on form 6i...
i have uploded images into the database of customers in my application using READ_IMAGE_FILE.. IT IS FINE...
But when i am trying retrieves records into the form.... i'm getting all the data except image... Image field is showing empty..
How can i get image from database to form
can u plz help me.....
thanks

What data type you used for storing image in database. If it is long raw, then you can place an image item within your data block on form and associate it with the column name. This should populate the image by itself.
Below para is from Forms Help.
Image items can be populated in the following ways:
+1. a fetch from a LONG RAW database column+
An image item in a data block is populated automatically when the end user or the application executes a query in the block. When a fetched image is modified or replaced, Form Builder marks that record as Changed, and the next commit operation saves the new image to the corresponding LONG RAW column in the database.
Note: You cannot write a SELECT statement to select a LONG RAW value INTO an image item.
+2. executing the READ_IMAGE_FILE built-in to read an image from the file system+
+(To dynamically write an image from an image item out to a file, use the built-in procedure WRITE_IMAGE_FILE.)+

How to store and retrieve XML messages in AQ using ESB/ BPE

Hello,
I am having a requirement which I feel should be fairly common - store and retrieve XML messages in AQ. However, I am struggling to decide which type of queue to use AQ or JMS...Here is the requirement
1. In an ESB, I want to read different kind of files using file adapter. Different kind as in, having different structure or schema
2. I want to create a queue that is capable of storing any kind of xml data. To this queue, I want to enqueue the message read in step 1.
3. In another process, say a BPEL, I want to dequeue the message and write into a file. The filename is retrieved from one of the header properties. I want to dequeue using a stored procedure, not by using a JMS or AQ Adapter (reason being that these adapters poll the queue, and consume a message immediately. However, I want to consume the message only when there is a business need)
My questions are:
1. What kind of queue I should create in the DB (What should be its payload type...XMLType? )... I guess the answer would also determine the adapter to be used - JMS or AQ
2. How I should map the xml data read from the file in step 1 to this adapter
Any help is highly appreciated.

You are right in suggesting that I dont need to store my XML data as xml in the DB...I dont want to too :) but its just that, thats the only option I can see at this time (the other track i am exploring is :
File adapter(XML) -> Convert to opaque (base64binary) -> Enqueue opaque to JMS (aq$_jms_bytes_message) ->Dequeue Opaque -> Write file opaquely.
In this I have hit the roadblock in trying to convert XML to base64binary...maybe some custom java function is needed...anyway)
Coming back to this thread, where I am trying the following
File adapter(XML) -> Enqueue as XML to queue ->Dequeue XML -> Write file opaquely.
PS: I think its important for me to mention that I am using SOA 10.1.3.1.0
I tried the steps you gave...after creating the queue, I am trying to create a JMS adapter. But the queue I created doesnt show up in the browse window of destinations for the JMS Adapter..That had led me to infer that JMS adapter cant be used
{color:#99cc00}CREATE OR REPLACE TYPE batchupdate_row_type AS OBJECT
(update_queue_id NUMBER
,upc VARCHAR2(20)
,price1 NUMBER);
{color}
{color:#99cc00}CREATE OR REPLACE TYPE batchupdate_rec_type AS VARRAY(9999999) OF batchupdate_row_type;
CREATE OR REPLACE TYPE payload_type AS OBJECT ( payload batchupdate_rec_type);
EXECUTE DBMS_AQADM.CREATE_QUEUE_TABLE ( queue_table => 'jmsuser.batch_update_queue_table', queue_payload_type => 'payload_type');
EXECUTE DBMS_AQADM.CREATE_QUEUE ( queue_name => 'batch_update_queue', queue_table => 'jmsuser.batch_update_queue_table');
EXECUTE DBMS_AQADM.START_QUEUE ( queue_name => 'batch_update_queue'); {color}
I also needed some opinion on whether the last step of my proposed solution ( Dequeue XML -> Write file opaquely) is possible. As I want to develop a service oblivious of the structure of the file, I dont want to create a file adapter based on a particular xsd...so I want to write whatever xml I am getting from the queue....is this step possible
