[Solved]How to upload / download BLOB images ADF - JSF

Hi everyone. I am a newbe ADF - JSF developer and I need to do a web app. in which I have to upload jpeg images to a table (in an oracle 8 DB) that has a BLOB column, also I need to be able to download images from the same table and show them in the web app. I have seen the examples on how to do this using the intermedia data types but I can't use this because the table already has a lot of records in it and the DB admin won't move a finger to migrate the data because other apps. are using the table.
I have been looking on the internet but haven't been able to find something that describes this process.
Thanks.

How to download blob image, inline to new browser tab or window

APEX V4.2.3
I have an interactive report with a blob download column which is set to inline. When I click on the "download" link the image appears automatically in same window as the APEX application. How do I download the image into a new browser tab? I need to squeeze 'target="_blank" ' somewhere but I don't know where as the link structure is hidden.
Here is the code for my download column in the Interactive Report.
select
decode(nvl(dbms_lob.getlength(BLOB_CONTENT),0),0,null,
'<img style="border: 4px solid #CCC; -moz-border-radius: 4px; -webkit-border-radius: 4px;" '||
'src="'||
apex_util.get_blob_file_src('P98_BLOB_CONTENT',image_id)||
'" height="100" width="100" alt="'||FILENAME||'" title="'||FILENAME||'" />')
as detail_img,
from "#OWNER#"."TIS_ATTACHMENTS"
thanks in advance
PaulP

I would suggest
SELECT ID, NAME,CASE WHEN NVL(dbms_lob.getlength(document),0) = 0
THEN NULL
ELSE CASE WHEN attach_mimetype like 'image%'
THEN '<img src="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'" />'
ELSE
'<a target="_blank" href="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'">Download</a>'
end
END new_img

How do I display blob (image) in a Portal Report

I am using 9ias 10222 and portal 30983 and I have a table that stores an image as a blob and have a varchar field to store the mime type. I have created a form to upload the image and can then query the form to display the image.
How do I dislay the image in a Portal Report/Dynamic Page Component. I have followed note 68016.1 but the retrieve_img_data procedure does not work it gives a wwv-11230 error.
Any ideas? Any help would be appreciated.
Thanks
Belinda

Hi,
Can you display what code you used for this? I followed note 172045.1 and everything compiles properly but when I run the report, I just get a box with a red X in it, like it is not finding the picture. I ran the procedure that downloads the image and it works fine from there. Thanks.

How to upload and display image using bsp application

hi
I just wants to know that
1- how to upload image from BSP page with attachment into sap server .?
2-how to display image in to BSP page(webpage).
thanks

Hello Gupta Prashant,
Just to upload and display an image, import image in MIME repository. Not only still images but also flash files can also be uploaded in the MIME repository. Once you import the image in it, use normal html code for image call;
<img src = "file.jpg/gif" width= height=>
Besides it, if your requirement is to store the image in the database and fetch it based on specified field-name, then you have to go for BLOBs i.e Binary Large Object, using this you can also store images, videos, pdfs, applications in the database.
MBLOB - Medium BLOBs store videos and pdfs,
LBLOB - Large BLOBs store movie files and applications.
You have got 2 ways to use it; some databases store BLOB objects into themselves and some store the path of the BLOB object maintained on the FTP server.
You can also implement it in ABAP;
read the following link and practice the tutorial;
[ Use of MIME Types|http://help.sap.com/saphelp_45b/helpdata/en/f1/b4a6c4df3911d18e080000e8a48612/content.htm]
also check this
[TYPES - LOB HANDLE|http://help.sap.com/abapdocu/en/ABAPTYPES_LOB_HANDLE.htm]
And looking at your question, in order to upload an image, you can make use of FILEUPLOAD tag provided by HTMLB.
Step 1: FILEUPLOAD provides a browse button to choose desired image file.
Step 2: Store that image in database using BLOBs.
Step 3: Retrieve the image using normal select query and display it on the screen.
Hope it helps you,
Zahack

How to upload the IPS image on SA540?

Hi Expert,
I've downloaded the IPS image file from Software Download Center, I'm wondering how to upload it to my SA540?
The SBIPS image file comes with .bin extension.
Truely,
Eric

As stated here: https://www.myciscocommunity.com/docs/DOC-13152
There will be a firmware update soon that will support IPS signatures.
However, in order to activate the IPS feature, you will need to purchase an IPS license SKU.
The IPS license is valid for 1 year.

How to Upload Web App images to different server?

Hello,
is it possible to configure web app item submission so images are uploaded to a different server (not BC)?
Customers are uploading lots of images with their web app items and I'm really getting short on server storage. Buying extra space in BC servers is a bit expensive, especially when I need loads of it. Smart thing would be to AUTO resize images to take much less space in the server but this is not possible with BC as no back end is allowed (maybe this could good improvement in next releases? "Auto resizing images to the value indicated"). Some customers are uploading images of up to 9 MB size X 20. I could limit upload size (i guess), but thats a big hit to UX, they should then bother resizing their images on some software before uploading.
So far my solution is to simply download images from the server, resize them manually with PS and then upload them back again. Maybe someone knows better solution than photoshop to automate the resizing process? I actually can automate the process with PS but image names changes and this is another problem. So a program to auto resize loads of images and keep their original names?
Another solution could be manually storing images to another server and retyping the links in web app items, but its a bit too crazy
Thanks

Hi Ray,
Indeed, this is not possible as an 'out of the box' feature and looks like a long-shot if attempting to use a separate server for storage.

How to display a BLOB (Image) in a EBS Report?

User requested to add a Logo image to a report which is called from E-Business Suite (EBS).
The image is currently stores in a BLOB column.
How can I make the image to display on the report?
Thanks!

I was trying to use the BLOB and display the image in a report.
Per your suggestion:
"Select the column in your query.
Create an item in the layout editor and set the source to this column.
Set File Format to Image."
My question was I dont know how to "set the source to this column" as you described above.
So, to work around it, I moved the image file phyically to the UNIX file system.
Then, created an item in the layout editor which required a valid "image file path" the property palette.
Since, the report was created under windows, it did not validate with UNIX file path.
That's why i need to perform extra steps to get the file path correct to work in UNIX.
EDIT:
I guess when you said "set the source to this column", you mean to map the "Field source" attribute in the property palette to the database column from query.
But depends on what item you want me to create (I created a "Link File" item) and it does not have the "Field source" attribute available to map to a database column.

How to upload/download file into/from blob column in ADF/JDev 11g.

Hello to all.
I found demo from Kuba user on that page: http://kuba.zilp.pl/?id=1
But that demo is for release 10g and too complicated for me for this time (I'm fish in Jdeveloper).
I can create some simple table view (of form view) with oracle connection with table with blob data.
Blob column will content doc/xls/pdf ...etc.
Now I can add two buttons for download and upload.
What I have to do in next time?
Is it possible to use some component or something?
Thank you
Ben

I was able to accomplish downloading from a blob, but I'm trying to dynamically set the ContentType.
As the table may contain different types of files, I'm setting the ContentType to #{row.Fileext}, where Fileext is set in SQL select as follows:
pseudocode: get file extension, and set the content type based on file extension.
sql select :decode(substr(fdv.file_name,instr(fdv.file_name,'.',-1,1)+1),'log','text/plain; charset=utf-8','xml','text/xml','xls','application/vnd.ms-excel','tif','image/tiff','jpg','image/jpeg','unknown')
I rather use a fuction/method, and tried the following instead:
ContentType = #{backingBeanScope.backing_processReqs.FileAttachContType}
where FileAttachContType =
public class ProcessReqs {
public String FileAttachContType() {
// code to substring filename for extension and decode values
return strContType
But I get the following error:
Error 500--Internal Server Error
          javax.el.PropertyNotFoundException: The class 'sunrider.reqpoportal.view.backing.ProcessReqs' does not have the property 'FileAttachContType'.
               at javax.el.BeanELResolver.getBeanProperty(BeanELResolver.java:547)

               at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:143)
Ideas?
PS: Kuba, I've been trying to get to your blog all day, and it would just time out.
Thanks everyone in advance!

How to upload a BLOB file from CMP Entity Beans

Hi,
I want to upload a .xls file as a BLOB using CMP. And also to get back the BLOB from the database through CMP. I am using oracle 8i DataBase and weblogic 8.1 server with weblogic workshop as IDE.
I don't have any idea to save a file as BLOB.
Could any one please help me to solve this as it is very urgent.
regards
KumudaRajarshi

I would just put the .xls file into a byte array in a
class that implements the serializable
interface. This class then becomes a column in your
database table(as a blob) represented by an
attribute in your entity bean. On sun appserver7
serializable is mapped to a blob column in the
database by default. You don't have to deal with a
blob at all in the code, just your
serializable type. You may have to use a type 2
driver to get it to work with files
over 4 or 5k.
See the appserver7 EJBdevguide, page 92 for details.could you descrbe the detail how to use the class to become the column as blob?
is that any sample code can be provided?
it's very urgent, please help..
thanks
