JCo - retrieving images (Urgent)

Hi,
I have to retrieve an image from SAP and render it in the portal. I get the data via Jco as a table and from the table I retrieve a binary stream. When I write the stream to a file the image doesn't display. Funny thing is, if I take the same image that is in SAP and read it from a file, the input stream data seems completely different from the data I get from SAP. Is something happening in the background that I am not aware of? Any help or ideas would be greatly appreciated

We had also problems with a PDF-file from R/3. The reason was that line feed etc where missing in the PDF-Datastream.
Do You get the data line by line in a JCO.Table?

Urgent : store and retrieve image to oracle database thru applet

hi all
i want the code sample for storing the image to oracle database
development enviornment:
server : oracle 9i , apache web server
client : ie6 browser
i am connecting to oracle database thru applet using oracle jdbc thin driver
can anyone give me details about storing image to db
1) what datatype should be used in table for image?
2) my image files are on client machine... can i directly read those files from browser or first i have to copy those files to server?
3) .gif files will do or what should be the fileformat?
4) java code to store it to database (i am using jdk1.3)
5) how to retrieve it back from database and display it in awt panel ?
its very urgent ...
i am doing some r&d and trying to do using blob....
but it will take some time ...
i will really be thankful if someone sends detail code....
thankx in advance ....

Hi,
The code below might answer few of your questions.
There is a restrcition on size of image, it must be less than 4KB.
//Code to insert image in database
//mytable is the table name that contains two fields in databse:name,image of type varchar and blob
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =null ;
Statement stmt =null ;
con =DriverManager.getConnection ("jdbc:oracle:thin:@<hostname>:1521:orclsid", "system","manager");
PreparedStatement preparedStatement = con.prepareStatement("insert into mytable (name,image) values (?,?)");
preparedStatement.setString(1,"Amol");
InputStream inputStream = new BufferedInputStream(new FileInputStream("C:\\WINNT\\Temp\\netscape\\images\\menubg.jpg"));
preparedStatement.setBinaryStream(2, inputStream, inputStream.available());
preparedStatement.executeUpdate();
preparedStatement.close();
inputStream.close(); To retrieve image,here is the snippet
ResultSet resultSet = stmt.executeQuery("select image from mytable'");
if (resultSet.next())
byte[] image1 = resultSet.getBytes("image");
FileOutputStream fos=new FileOutputStream("c://splash11.jpg"); //will retrieve bytes and create a file
//by the name specified
fos.write(image1);

How to retrieve image from a document

Hi
I am a beginner to Adobe InDesign SDK (CS4) and was needing some help. Here is the sceneario
I have a simple InDesign document with an image in it. I am trying to retrieve the image and do some proprietory actions on it.
I am wondering if there is an InDesign API which can retrieve image on a document. What is the return value from such an API. (e.g does the API return a pointer to the image object or maybe location of the image on the filesystem ? ). What I am trying to do is once I can get a "handle" to the returned image, I would like to manipulate it and save it in a proprietory format.
Any pointers on this would be highly appreciated
thanks!
Sam

Hi,
You can get the path of the linked image file and then you can manipulate this image.
I think ILinkUtils and ILink will certainly help.
You can also check (for better understanding) CHM->PortingGuide->Links Archtecture.
Thanks.

Retrieving images for a java game

i am currently trying to make a game whereby i have to retrieve images from a file and display it to the screen. I am able to do this using applets but the game i am implementing does not use applets - it only makes use of awt and swing components. any advice given would be gretly appreciated as i have been trying to do this for days now!

Ive read all the tutorials and it still wont work. Ive tried both the
ImageIcon anIcon=new ImageIcon("image.jpg");
and the
Image image = Toolkit.getDefaultToolkit().getImage("blah.gif" );
I was wondering could it be something to do with XP or the java compiler im using?im using Forte for Java v3.The code complies fine but when i run it nothing appears!

Retrieving images in lightroom

I cannot seem to retrieve images from the Library mode. I refer to images that have previously been downloaded and most ranked, tweaked, etc. The message I get is that there is no picture. When I try then to retrieve from the original source, the message is that the photos have already been imported. Darned if I can find them.
I am currently finding the TIF at the original source, re-naming it slightly and then I can import it -- only to lose it again. A real pain!
Something I am doing is not right. Tell me.

Check if you have a Filter applied. Then un-apply it

Saving/Retrieving Images

I want to use a mySQL database to store and retrieve images. The images will first be read from a File and saved to a table, then later the image should be read from the table into a Java image object.
I'm not sure what field to use (TEXT or BLOB) and how to save the image to the database, and how to read the field from the database into an Image object.
Any suggestions?

You can save and retrieve images in MySQL as BLOB's. However, the default settings of MySQL will limit the size of your images to about 1 MB in size. This is a limitation of the communication settings, and not a table limitation. To change the setting, you need to edit the max_allowed_packet in the my.cnf configuration file.

Using Java to Retrieve Images from Oracle

OracleResultSet.getCustomDatum method is deprecated. I was using this method to retrieve an ORDImage from an Oracle 9i database. What are developers using instead of getCustomDatum to retrieve images from the database. Thanks for all help in this matter.

Hi use getBinaryStream(java.lang.String) or getBinaryStream(int) of java.sql.ResultSet for retrieving images from database
Hope it will be useful

create a table with 2 fields (label varchar2(25) ,image blob)
create a data block with the above table
place 2 buttons (get and save) on the form
trigger for get_button (// when_button_pressed event)
read_image_file(:block_name.text_item_name,'jpg',blockname.image_item_name); --this will retrieve image from the local system and place it on the image item
(enter the full path of image with extension in text_item after complie)

Please help me soon, my email is: [email protected]
Bye , Rea

Probably a bit late, but I just got the same problem.
Oracle seems to instantiate a class which is not fully defined-
oracle.sql.BLOB. This class has abstract methods, and is therefore
an abstract class.
In short, Oracle are stupid fools. How they managed to instantiate
an abstract class in the first place should be of concern to the
Java gurus, however. Native code in the OCI driver perhaps?
If you still need help, you could try uning the Thin driver- or
a database with a JDBC driver which actually meets the spec. There
are third party Oracle drivers which might fit the bill- they
usually cost money, however.

How to retrieve image?

i am working with j2me. in that i need to store and retrieve a image in the database. storing the image is working properly, but retrieving does not working. if any one knows help me...

there is something called "blob" - datatype in oracle where u can store images. for example, in char - datatype it will take only one byte, for float - datatype it will take 32 bytes, like wise u can store images using blob datatype for storing images in oracle database. and for retreiving those images u need a front end tool to display those retrieved image like JSP. for example if u r attaching any photo for ur passport. and after that if u want to see the status any one day u can ensure that status by seeing ur photo that u have sent before. this is because they have saved ur photo using the "blob" datatype....just check it

Question on retrieve image from mysql

i want to retrieve image from mysql database and display on GUI
can anyone tell me how to do
Thank you

You can use the JDBC API for Java Database Connectivity. With this you can obtain data from the database using Java. There is an excellent tutorial here at Sun.com: http://www.google.com/search?q=jdbc+tutorial+site:sun.com You can get the MySQL JDBC driver at their own site: http://www.google.com/search?q=download+jdbc+driver+site:mysql.com Get the most recent version which suits your environment. There is also good documentation available over there.
For displaying in the UI, the approach differs per UI. As you didn't mention which UI you are using, I can't help you further in detail.
