Iframe of a Blob Content in Apex form/report

Hi All
I am developing a application where users will upload documents which will be stored in blob column. Now the requirement is to show the document with in the page using Iframe. Can some one please suggest the steps to show the blob content in iframe.
Thanks in Advance.
regards
Srini.

You can show the documents in an iframe only if your browser has an appropriate plugin (like to most browsers have it for pdf documents). Otherwise you will be forced to either save the document or open it with the appropriate programm. Means, your application will probably fail to show the documents in an iframe for all other document types other than pdf.
I have no special case explaining how to display a document in an iframe but you can inspect it here:

Downloading blob content from a custom table

In our hosted Apex application, the following code from the Application Express Developer's Guide works great for allowing a user to download blob content from one of our custom tables via a download button. However, the code doesn't work on the Oracle Cloud because the "owa_util" package is no longer available. The code is as follows:
CREATE OR REPLACE PROCEDURE download_my_file(p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end download_my_file;
Besides using web services, does anyone know of a way to do this? Is there a way to add access to the "owa_util" package in the cloud? I have also tried apex_util.get_blob_file_src but that is also unavailable in the Oracle Cloud.
Thanks,
Steve

Following Joel's advice:
The way I solved this was to split the code between two page processes and one application process. The download button first calls a page process to move the report data into a blob column and then calls another page process which is of "run application process" type. This calls the application level process where the download code, shown below, is called.
Notice the following changes to the code from the one posted earlier (also from Joel)
1) added sys.htp.init;
2) "sys." to all htp, owa and wpg_docload calls
3) added apex_application.stop_apex_engine; after the wpg_docload statement at the bottom of the script.
Now the download button launches a "save as" dialog box and the report content is downloaded to the client.
The code now looks like:
CREATE OR REPLACE PROCEDURE download_my_file(p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM oehr_file_subject
WHERE id = p_file;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
sys.htp.init;
sys.owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
sys.htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
sys. htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
sys.owa_util.http_header_close;
-- download the BLOB
sys.wpg_docload.download_file( Lob_loc );
apex_application.stop_apex_engine;
end download_my_file;
Thanks Joel for your help.

Display blob content as pdf file

Dear Expert,
Currently i'm using oracle apex 3.0.1.
I'm having a problem on displaying blob content (from database table) as pdf file on oracle application express but i'm able to save to download the pdf.
Below is the procedure that i used to display blob content,
PROCEDURE lf_html_pdf (pv_image IN VARCHAR2, pv_index IN NUMBER) is
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc BLOB;

exception
when others then
null;
end;

HTP.p ('Content-length: ' || l_length);
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (lob_loc);
END lf_html_pdf;
I get the error message as below when i execute the procedure above;

Send Blob Contents to Client machine as Attachment

I am able to see the blob contents in the client window but the file does not show as attachment which is my main purpose-- to give the user the option either to open the file or to save the file on his machine. I am also setting the setHeader as attachment , but nothing happens....and sometimes it shows a dialog box to open my jsp file itself rather than the desired file... sending you the code ..please help
File file1 = new File("c:\\Test.java");
byte[] buffer = new byte[(int)file1.length()];
BufferedInputStream is = new BufferedInputStream(new FileInputStream(file1));
is.read(buffer, 0, (int)file1.length());
is.close();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
baos.write(buffer, 0, (int)file1.length());
System.out.println(baos.toString());
byte[] pass = baos.toByteArray();
response.setHeader("Content-Desposition", "attachment;filename=untitled.java");
response.setContentType("application/octet-stream");
//Send content to Browser
ServletOutputStream servletOut = response.getOutputStream();
servletOut.write(pass);
servletOut.close();

It works,
you have a type!
response.setHeader("Content-Desposition", "attachment;filename=untitled.java");
It should be "Content-Disposition" not "Content-Desposition"
try it out.
cheers

Upload blob content

Hi all,
I am facing an issue, while inserting blob content into database.
I am having a table(table1) with following column cat(char) PK,upload blob,mimetype varchar(1000),filetype varchar(1000)
For inserting values into DB(table1) i am using the following process, here it works fine
BEGIN
IF (:P9_X IS NOT NULL)
THEN
INSERT INTO table1(cat,UPLOAD,MIMETYPE,FILETYPE)
SELECT :p9_cat,blob_content,MIME_TYPE,FILE_TYPE FROM wwv_flow_files where name=:P9_X;
END IF;
END;
But, when i tried to have ID(number PK) in table1 with above process, i am not able to insert values. While creating process it throws following error.
INSERT INTO table1(ID,UPLOAD,MIMETYPE,FILETYPE)
SELECT DEL_SEQ.NEXTVAL,blob_content,MIME_TYPE,FILE_TYPE FROM wwv_flow_files where name=:P9_X;
ORA-06550: line 6, column 24: PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got BLOB ORA-06550: line 5, column 7: PL/SQL: SQL Statement ignored
Thanks.

Hi,
If I understand correctly, your table UPLOAD column format is number and you try insert BLOB to it.

Possible to take a blob content out of table

Hi,
i have a table in which the image is getting storing in the table in blob content.
Whether it is possible to copy that image which is stored in the table to outside, so that i can edit the photo in paint.
It is possible to take that blobcontent of the image out of the table.
If so, how to achieve it.

Discoverer portlet error: blob content is empty.

I created 6 disco reports and some are giving error, Failed to retrieve an entry from the cache in the Discoverer Portlet Repository. The BLOB content is empty.
This error only happens with certain users. The users can log directly into discoveer viewer and see the reports. Just not in portal. It also gives me this error randomly and I have to delete the portlet and recreate it. Has anyone else experienced this problem.
BH

I copied and pasted the above code to my jsp. It works fine for me . I get the content correctly. Tried on a ps 7.1
hope the additional character "/>" is not intended
<td>city</td><td><input name="city"value="city"/>/></td>

See BLOB contents on Oracle FORMS

Is there anyway that I can see the BLOB object contents in Oracle Forms? For example, if I have a word document in BLOB, I should be able to open it in Oracle forms. I've already posted this today, but just for clarification, I'm reposting this with exact requirements. My client wishes to see data from a table and in that a BLOB object is one of the columns. For each row, there is a word document, which should also be displayed (or at least a link) on Form. If clicked on the link, the BLOB content, i.e., the word document should get opened. Please let me know if there is any way. Francois was trying to help me, I think this explanation makes it clear for him and also others. I don't have webutil library and my Forms version is 6.0.8.18.3. Please help me soon. I'm in an urgent realease this weekend and need this deliberately. It is not possible to upgrade to newer version for me.
Thanks
Sarma.

In fact, I just had to do this today. It works as expected using an image item on the BLOB column. I am at 10.1.2.0.2, if that makes any difference. Are you positive you have data in the BLOB column? I noticed that after loading a table with image items, I used SQL Developer to look at the table to ensure there was data in the rows. After that, the images no longer appeared in the form. I had to reload the table, then all was well again.

Converting an image as a blob content from .gif format to .jpg format

Hi
Does anyone know how to convert a blob content from .gif format to .jpg format?
I've tried looking at the process-method of intermedia, but I can't figure out how it's supposed to work... I'm on a 10.2.0.2 standard edition database
I simply have a blob containing a gif-image, and I want it to be convertet to a jpg-image for further use
Can anyone help?
Thank you

useWhat OS is the database running on? If it is a *nix flavour, you can call out to image magick convert utility (it is pre-installed on most linux variants, and you can compile it from source for other unixes). So you would probably store the blob into a temp file on the database server, call out to the shell to execute convert, and then load a blob from the converted file. See http://imagemagick.org for more information.
If that is not an option, you might be able to use Java Advanced Imaging API from a Java stored proc to convert between those image formats. See http://java.sun.com/products/java-media/jai/downloads/download-1_1_2.html

Display Blob content in Apex

Hi folks
I hope you can see HTML Expression code now.
I have PDFs stored in BLOB columns along with FILE_ID column in the database.
I want to display these to the APEX user on the page at runtime.
I have created a SQL Query report page to display FILE_ID column.
I am using HTML Expression property of the FILE_ID column to pull the image from the table using PROC_DISPLAY_DOCUMENT procedure.
I typed folowing code int the HTML Expression text area of the FILE_ID column of the report page :
[!-- img src="#OWNER#.proc_display_document?p_id=#file_id#" ]
I am using following Procedure code:
create or replace procedure "PROC_DISPLAY_DOCUMENT"(p_id number) **
mimetype varchar2(48);
n_length number;
s_filename varchar2(400);
lob_image blob;
Begin
select MIME_TYPE,dbms_lob.getlength(blob_content),file_name,blob_content
into s_mime_type,n_length,s_filename,lob_image
from tbl_upload_file
where file_id = p_id;
owa_util.mime_header(nvl(s_mime_type, 'application/octet' ),false);
--set the size so the browser knows how much it will be downloading
htp.p( 'content-length: '|| n_length );
--The file name will be used by the browser if the users does a "save as"
htp.p( 'content-Disposition: filename="' || s_filename ||'"');
owa_util.http_header_close;
--Download the BLOB
wpg_docload.download_file( lob_image );
exception
WHEN NO_DATA_FOUND THEN
RAISE_APPLICATION_ERROR(-202121,'Record matching screenfield filename not found, PROC_DISPLAY_DOCUMENT.');
end;
--This is very Important
--grant execute on PROC_DISPLAY_DOCUMENT to public;
This code does not work and Apex report does not display PDF image.
Any help to troubleshoot this code will be appreciated.
Thank you in advance.
Jaya

create or replace procedure "PROC_DISPLAY_DOCUMENT"(p_id number) **
mimetype varchar2(48); ... Doesn't look correct to me. What are the ** for?
Does the procedure compile?
This code does not workHow did you come to this conclusion? Any error message you got?

I have a simple form where user can attach file and save the records. I iterate through wwv_flow_files and get the file and save it to a custom table which has BLOB column. On another report page i display uploaded file details. What i need is, there must be a column with download link when user clink the link appropriate file should be downloaded. How can i do this ?
Really appreciate if someone can assist me on this.
Thanks Guys.

See About BLOB Support in Forms and Reports.
There's an OBE tutorial that followed the introduction of declarative BLOB support in 3.1 as well. (An earlier version but it is still relevant to APEX 4.x.)
(Please make an effort to consult the documentation and thoroughly search the forum for previous coverage of a topic. This is a much discussed question.)
