Image from database blob column

Hi all,
Is it possible to show the image stored in data base column(blob type) in image component without using servlet.? ( I mean in a declarative way.)
I saw lot of samples which all using servlet. I needed to know whether it is possible to show image in more simple way.
Thanks,
Gijith.

No, using a servlet is the way to go.

Error while opening PDF file downloaded from database Blob column

Hi All,
I am working on jdev 11.1.1.4.0.
In my use-case I am using filedownload Actionlistner on a link to get the PDF file stored in the database in blob field. These files are being uploaded from other use-case in adf only.
After getting the dialog box to open/save/cancel for the PDF file when i click on open then i am getting an error *'Adobe Reader could not open 'abc.pdf' because it is either not a supported file type*
or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly docoded)' for some files , and to my surprise I am able to open some files.
When I open these PDF files separately from desktop I am able to view the content of each and every file in adobe reader.
I dont know where the problem exactly lies , while uploading/downloading the file . Any ideas/thoughts to resolve this issue?
Thanks
Kanika

Thanks a lot Timo...!!!
I checked the PDF file downloaded directly from the blob column in DB, there only it is corrupted so must be the problem in uploading the file. I am checking the code line by line,, but no problem in setting the file content type,size etc.
Here is the code snippet ..
byte[] buff;
buff = new byte[(int)length]; -- Length is the file size
int bytesRead = is.read(buff);
for (int i = 0; bytesRead < buff.length; i++) {
// int b = is.read();
int b = is.read();
if (b == -1)
break;
buff[i] = (byte)b;
BlobDomain blobDomian = new BlobDomain((buff));
TestVORow = (TestVORow Impl)TestVO.createRow();
if(blobDomian != null) {
TestVORow.setAttachment(blobDomian);
am.getTransaction().commit();
This seems to be Ok to me..the same issue, file is still corrupting.
Any thoughts from your side ???
Thanks
Kanika
The problem is resolved.
Changes made are instead of
InputStream is;
used ... BufferedInputStream bis ;
and after
for (int i = 0; bytesRead < buff.length; i++) {
// int b = bis.read();
int b = bis.read();
if (b == -1)
break;
buff[i] = (byte)b;
bis.close(); // use this close bufferedInput Stream.
Able to open each and every file now..Thanks for your suggestions Timo and Frank.

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

How to retrieve am image from database

hi ,
i hav a requirement that, i hav to store and retrive an image from database(postgresql)and palce it on JLabel.i successfully stored an image into database .while retrieving an image from database im not getting the image .please any one can help me how to retrieve an image and place it in JLabel.
This the code for inserting an image:
Class.forName("org.postgresql.Driver");
Connection conn = DriverManager.getConnection("jdbc:postgresql://localhost:port/database", "username", "pwd");
System.out.println("Connection established");
String INSERT_PICTURE = "insert into imagedata(imageid,data) values (?, ?)";
FileInputStream fis = null;
PreparedStatement ps = null;
try {
conn.setAutoCommit(false);
File file = new File("photo.jpg");
fis = new FileInputStream(file);
ps = conn.prepareStatement(INSERT_PICTURE);
ps.setInt(1, 2);
ps.setBinaryStream(2, fis, (int) file.length());
ps.executeUpdate();
conn.commit();
catch(Exception ex)
ex.printStackTrace();
finally {
ps.close();
fis.close();This is the code for retrieve an image :
Class.forName("org.postgresql.Driver");

byte[] imgbytes = null;
String INSERT_PICTURE = "select imageid,data from imagedata ";

InputStream file=rs.getBinaryStream(2);
System.out.println("FILE : "+file);
catch(SQLException a)
finally {
stmt.close();please anyone can help meee
thanks

You basically save a File to the database, so you can just re-write the data from the file back temporarily and load it into the application using the ImageIO class
// create necessary connection and statement objects
// retrieve image column
ResultSet rs = stmt.executeQuery("SELECT Image FROM dataTable");
rs.next();
Blob imageData = rs.getBlob("Image");
if( imageData != null ) {
    try {
        File tmpFile = new File("tmpImage");
        FileOutputStream fos = new FileOutputStream(tmpFile);
            fos.write( imageData.getBytes(1L, (int)imageData.length()) );
            fos.close();
        tmpFile.deleteOnExit();
        ImageIcon icon = new ImageIcon( ImageIO.read(tmpFile) );
        JOptionPane.showMessageDialog(null, icon);
    } catch(IOException ioe) {
        ioe.printStackTrace();
        JOptionPane.showMessageDialog(null, "Failed To Load Image Data", "Load Error",
                JOptionPane.ERROR_MESSAGE);

Display image from database with jspSmart

Hi
I have successfully uploaded and saved images into oracle(8.1.5) table DATA_TYPE(dtid number, iconname varchar2(30), icon blob). When I try to display a specific icon in my browser, I get "javax.servlet.ServletException: General error" at:
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
My code looks like this:
imgModifyDataType.jsp
<%
ResultSet myResultSet = null;
Statement myStatement = null;
Connection myConnection = null;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
myConnection = DriverManager.getConnection("Jdbc:Odbc:Te","te","te");
String iconName;
String pDTID = request.getParameter("dtid");
String mySQL = "Select iconname, icon from data_types where dtid=?";
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
pstmt.setString(1,pDTID);
myResultSet = pstmt.executeQuery();
iconName = myResultSet.getString("iconname");
myUpload.initialize(pageContext);
myUpload.downloadField(myResultSet,"icon","application/x-msdownload", iconName);
%>
I call this JSP from another JSP like this:
<img src="imgModifyDataType.jsp?dtid=<%=pDTID%>">
If we cannt display image with the help of another jsp like this then please guide me how to modify the imgModifyDataType.jsp to a servlet because I have never worked in servlets.
Please help

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.)+

Rendering images based on BLOB columns

Hello
I'm using JDevelpor 10G ..
I want to render image from BLOB column , and its the first time working with servlet , I read this article
http://www.pascalalma.net/2008/04/22/oracle-adf-medior-rendering-images-based-on-blob-columns/
and I want to ask some questions ??
- How can I check that the servlet is run .. I use this to call the servlet "" Do not laugh .. I am really new "
<af:objectImage source="/render_image?img_id=#{row.ImageId}"/>
You should read the article to understand my question
rgds

done , my problem was with mapping

RE: Images from Database into W

I've found that a good way to store images was not in the database, but
in files on the server in GIF format and then store the filenames in the
database. That way you avoid the BinaryData mess, the cursor
requirement for blobs, and can store in a compressed form..
You just have the service read in the image from the data file and pass
it back to the requestor, if I remember right.. Also nice because the
same GIF files can be used in normal HTML web pages..

Reply: Images from Database into Web SDK 1.1 page
Hi,
I want to be able to read images in from a database and have Forte
generate a web page with those images.
Does anyone know what the MIME type would be for a Forte ImageData
object? Do I have to store the images into the database in gif format
or is there some other MIME format that Forte uses to store ImageData
objects. Also, can Netscape or Internet Explorer read those images?
Here is the ReturnImage page builder method I created:
=============================================================
Response : HTTPResponse = new();
LUIObject_ID : Integer;
LUIObject_TD : TextData = new();
aLUIObject : LUIObject;
aBinaryData : BinaryData = new();
aStream : MemoryStream = new();
// Retrieve LUIObject_ID from http parameters
LUIObject_TD = pRequest.FindNameValue('LUIObject_ID');
LUIObject_ID = LUIObject_TD.IntegerValue;
// Retrieve aLUIObject for the specified LUIObject_ID from the
database.
// This object contains various ImageData attributes which contain the
// icons to display on the web page.
aLUIObject = SODIInfraSOMgrSO.SelectLUIObject(LUIObject_ID);
aBinaryData.SetAllocatedSize(aLUIObject.ClosedLargeIconSize);
aStream.Open(accessMode = SP_AM_READ_WRITE, isBinary = TRUE);
aStream.WriteSerialized(object=aLUIObject.ClosedLargeIcon);
aStream.Seek(0);
aStream.ReadBinary(target = aBinaryData);
// Not sure what MIME type to specify here for ImageData objects
// read in from a database. Any ideas??????????
Response.AssignBinaryResponse(aBinaryData, 'image/x-bitmap');
return Response;
===============================================================

Hello Denis Segard,
I also try the same method and I use OLE container to store the images into database in Oracle forms 6i.
But, if i try to retrieve the images in report i got that error.
Anyway i store the images into the database but why i shouldn't retrieve it in reports and i can retrieve the images in forms
Is there any problem in my design.
Is there any other easy way to store the images into database in oracle forms 6i...
Waiting 4 ur reply!!!!!!!!

Inserting Image into a BLOB column in Oracle9i

Hi,
I am unable to insert image into a BLOB column. I am using Forms 6i REL 2 and Oracle 9i. But I could do it on Oracle 8i with same Forms version.
Same thing is true for CLOB in 9i.
Would you please try with this code?
TABLE
Create table x
(Id number,
Name CLOB,
Pict BLOB);
WHEN-BUTTON-PRESSED trigge
declare
     x varchar2(265);
begin
     x := get_file_name;
     read_image_file (x, 'GIF', 'picture.pict');
end;
Take care,
Tarek

Forms 9i and Oracle 9i work fine together for this case.

Displaying the image stored in Blob column

Hi all,
I'm trying to print the report with an image. I've stored the image in a Blob column and the format of the image is Jpg.
I'm using the Reports 10g(10.1.2.0.2). When I'm trying to print the report, I'm getting an error Rep-62203. I want to know whether there are any settings which i need to set to display the image item. I mean to say that are there any registry settings.
Regards,
Alok Dubey
