How to store and retrieve .jpeg images from oracle database.
I am using JSP. Can anybody tell me the process of doing it.
I believe Oracle reccommends to use BLOBs for storing large binary data.
Check on DBMS_LOB package on Oracle documentation: it has all the API's you
need.

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
MonarchHello
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 do I transfer a jpeg image from my desktop to pages on my ipad2
How do I transfer a jpeg image from my desktop to pages on my ipad2 ? Need to prepare a document urgently !!
Well you actually need to provide some details to get assistance
Why will it "not allow it?"
If you have exported to a finder folder on the desk top then your issue is not an iPhoto issue but a system issue - but to resolve it exact details are needed including exact error messages
The general answer to moving a folder from the desktop to an external drive it to drag it there

LRv3.2 Networking with an Asst , How to store and retrieve updated work on Win7?
LRv3.2 Networking with an Asst , How to store and retrieve updated work on Win7 Network?
We have a working 1gig network in Win7 PRO 64-bit. and using LRv3.2
* How do I configure our Files or Cataloges "so" ALL Edits are veiwable/edit to all? (we don't work on the Same Shoot/Folder at the same time)
I NEED to see, ALL the LR Edits (is great with DNG files
*** BUT, what I cannot see if I remember correctly (with just the DNG sharing) is the CROP or Virtual Copys ... possibly the Brush edits.
HOW, do I configure to be able to read and edit ... ALL of the updated/saved Edits??? (after it is done by my asst.)
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,
HGAloha 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,

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 -

StephenSelect clip in timeline and place the playhead over the frame you want to save as a JPEG. Open the share window ( Button on far right of tool bar) and select 'Save current frame'. If you don't see that option click on add destination and select the Save current frame choice. It will be added to your share options.

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¨æ款æºç½ç»
while trying to retrieve it, it shows
èª?æ款æºç½?
^ ^
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¨æ款æºç½ç»";
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
PDhi, 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!

How to access data in AS 400 from Oracle database
Hi
Could you please help me on accessing data in AS 400 from Oracle database? what are the main things to do? Any private documentation or any oracle metalink note please...Hi
Please find the details given below....Any body can help me on this please....
Issue Description: The stock status report to be developed at SATN has some information that is currently calculated and stored in the Fox/pro system. A real time ODBC needs to be done to the AS/400 system to retrieve values for the respective fields. This has never been tested before as it impacts many areas.
The DBA team need to work to establish such a relationship and a report needs to be written in Oracle to have this tested on a real time basis. Mapping needs to be developed on the Oracle side to grab the correct fields -
How to store and retrieve a PDF form to SQL Server from LiveCycle?
My intention is to save a complete PDF form into a database and then later on retrieve this form from DB.
To do this, SQL Server has got two datatypes, image or Varbinary(max). I am able to store a PDF using "Execute SQL Statement"(I have written an Insert statement). Some value is being written into DB as well.
But when I try to retrieve this record using "Query Single Row"(I store the result to a doc variable), the retrieved PDF is of an unknown type and cannot be opened by Adobe Reader.
I am not sure if my approach is correct. Is it possible to store/retrieve a PDF form to/from a DB through LiveCycle?
If yes, please give me some guidance.hi
am not sure
but u can use the same concept as storing image in db and retrieve..
create a blob column
parse that pdf and store into that column.
again u retrieve the content and via file io make the same name with pdf extension.. -

at ImageDemo.main(ImageDemo.java:28)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.
