Hi kavita,
               In Webdynpro u r using attribute of type Resource ,which is binded to FileUpload UI element. From this attribute, u get file in Input stream format which can be converted into byte array like this
byte fileData[] = null;
      try{
            InputStream fileIs = wdContext.currentFile().getFileData().read(false);
            ByteArrayOutputStream bOut = new ByteArrayOutputStream();
            int length;
            byte[] part = new byte[10 * 1024];
            while ((length = fileIs.read(part)) != -1) {
                  bOut.write(part, 0, length);
            fileIs.close();
            fileData = bOut.toByteArray();
            bOut.close();
      } catch (Exception e) {
            wdComponentAPI.getMessageManager().reportSuccess(e.toString());
In webservice u can take a the byte array as input parameter where the uploaded file will be passed as byte array .
In DB u can store it as BLOB .
in case of any other doubt u can revert back to me.

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,

Upload and display image in webside

Hello Friends,
I am developing an auction web site ,and facing some problem so I need your help.
There is some confusion about uploading and displaying images in website .In web based
application if I want to upload images than where have to store the images database or server
side any folder .I have not idea about that please send your ideas and sussesions.
Second problem is What is the best way to display images in webside either giving a direct
path of server side image folder or I need to retrieve all images from database .
I have no idea about it please send me your guideline which are usefull for me to implement in my
website.
what is the correct way to upload and display images in website ?
Thanks . Have a nice day.

If you are using a Container you just leave your image files in the home directory of your web application. And forget this idea about database. It´s not necessary in this case.
To display the images just use HTML, <img src="url">.

Multiple image upload with save to database problem

I am developing some backend work for a client, and we recently used the Multiple image upload with save to database wizard without a problem. A few days later, we noticed that we could only upload a single file at a time - it seems that the coding is no longer able to access the flash part of this and is using the javasript function instead. I know the web hosting company has made some changes on the server, and I did some reearch and it seems that there could be an issue with Flash 10, but has anyone else experienced anything like this? Any help is greatly appreciated.
Thanks.
Jeremy

Thank you for the responses. I have already updated awhile ago, so I am wondering what happened. Not sure if during the server update, some files were replaced (unless I totally forgot to update to 1.0.1 on this site). So I reinstalled 1.0.1, deleted the includes folder from the server and uploaded my includes folder and it now works again.
Again, thanks for the help.

Multiple image upload with save to database wizard problem

hi,
i need to upload multiple images (6) in a table called pictures. i will need the names stored in the database and the files uploaded on the server. since i am new to dreamweaver i can not figure out on how to make this work.
the multiple image upload wizard uploads the images fine and creates a subfolder with the right id but i have no file names in the database at this point. i tried the multiple image upload with save to database wizard but i only get one upload button. it worked fine with one image but i need 6 pics uploaded. the i tried to first upload the pictures with the multiple image upload wizard and use the update wizard to add the names afterwards but that did not work either. hmm. would be great if someone could help me out.
thanks, jan

Multiple Image upload with save to database

Hi everyone,
I wonder whether anyone can help me, I have been trying to use the multiple image upload with save to database wizard. When I create the page and upload it and then view it in Safari the only thing that is on the page is an upload button. When I press the upload button I am able to browse my files and select them. When this window closes a flash loading value is shown but no images have been uploaded.
Am I missing anything? I have had no problems uploading single files and creating albums. I want to create an online gallery so that I can do a multiple upload to a specific album if this is possible.
Cheers
Sarah

Hi Sarah,
>>
but only the filename appeared in the database and no other information was stored.
>>
that´s how it´s been designed also in the "single upload" -- the path_to_the_folder where the files sit in have to be determined elsewhere
>>
{wedimg_idalb}
>>
I don´t see any reference to this "dynamic data" placeholder in any of your table columns you posted -- where does this one come from ?
>>
1. I have multiple clients and each client has their own set of images.
2. Each set of client images must be linked to an album via the album ID
>>
do you have any "foreign key" which is related to the user_table´s ID in order to make user ID 2 upload his images in album ID 2 ? How will the upload page "know" where the images are going to be uploaded to ?
>>
and the album page, wedding_alb
>>
to my mind *this* table would itself need a foreign key to the user_table in order to "map" record 2 to user ID 2 -- or do I miss something ?

Multiple Image Upload with save to database not working in IE anymore

Since updating IE to SP3 ADDT Multiple Image Upload with save to database does not work anymore in IE. It will show a regular file upload field, an does not allow selection of multiple files. It does work in Firefox, but not all my clients use firefox.
PSE Advice.

I would consider buying some pluggins from dmxzone.com. They
may cost a
bit upfront but in the long run, you've probably be saving a
lot of
headaches.

If time's an issue, with these plugins, you could probably
be up and
running in a half hour. George has some really nice pluggins
for
Dreamweaver and well worth the money.

Image upload with save to database

Quick question guys,
Can Image upload with save to database be added to an existing form in order to save other info as well as the file name to the database.
Thanks
Col F

Hi,
Not looking at any code you have an upload button for the video and an insert for the form. So both forms are independent of each other it looks like, thats why when you do one you only get that info and when you do the other you only get the other info. You should just make one form with the uploader included. Make one form with all the fields included (movie name, movie page, movie description, movie file) after the form is completed then select the file field and go to...

Image Upload and Resize Trigger Order Question

Hello All,
I do enjoy and like using the ADDT, however I do have a problem with the Image Upload and Resize trigger.
I understand that this trigger is of the AFTER type, and as such, the insert record I have on the page is implemented first and the data is inserted into the table, then images uploaded provided they are smaller than 200 kB in size.
However, as I have a field that is unique in the database, if the upload fails I am unable to upload any files which are under the size and put that information into the database, as there is already a record with the unique value.
Is there an easy way to work around this by trying to capture the error before the data is inserted into the database?
An idea I have is to: check the unique field with the value to be inserted, if fails, change unique value -> nothing inserted yet, no files uploaded.
If the unique check passes, insert remaining data and trigger the upload and resize image trigger, once that is complete, have an update of the table to update with the unique value.
I can see the above working, (I think), but I just have to write the code to implement the idea.
I am not sure how to use the roll-back triggers either, if the Upload Image trigger fails, to remove the inserted record. But if I can manage the roll-back trigger to remove the record, that is an option to consider for what I want to achieve.
Thanks to any help people can provide.
Cheers,
Ian.

Thank you for your reply.
I have a work-around, I have split the forms over two pages, rather than put everything on one page - which introduced another issue, to which I have made a work-around of sorts too.
The two forms, on different pages, is probably a better idea in terms of better management of data input. The work-around was a Header redirect based on a form variable, as, if I used a Custom Trigger to dynamically generate a new URL, it generated an escaped-encoded URL - to which I have not figured out how to fix.
So, in the meantime, it works, so I will settle for that at the moment.
Again, thanks for you reply.

Image: display from local drive, upload to server file system, and display from server

Hello,
I am using jdev 11.1.2.4.0...
The requirement is that users would like to upload images from their local drive to server drive and they would like display images from server drive later.
We don't want to keep images in database. I am not sure what the solution should be; however, I plan to ....
1. create a table to keep an information of images -- image_id, image_location (server drive), image_filename
2. create a page where users can enter image information and specific filename from a local drive (I think I will use inputFile component) and provide the preview button to display an image on screen before save it. To save data is to save information to the database and copy an image file to the server drive (the destination location for image files is predefined.)
3. create another page where users can browse information from the database and display an image for a selected record by getting from the server.
I need suggestions on...
1. how to display an image on page from the local drive?
2. how to copy a file from a local drive to a server?
3. how to display an image on page from the server drive?
Thank you.

Where Timo saves images to the database, you save it to the file system (examples on how to do this from Java are available plenty if you just Google for it). Similar to Timo you then use the image tag to display images. The difference is that you can directly add the URL from the database table.
The benefit of using a database to host images is that you are not dependent on file server structures though

Need help with image upload and preview display

hi guys,
I'm trying to upload image and then display it as a preview, but when upload form submits to the same page image placeholder does not refreshes it's source and displays the same image as before.
Image 4.jpg already exists.
I upload it with nameConflict = "overwrite"
upload form points to the same page, therefore page reloads
In IE image placeholder does not display the new image, but shows the old one until I refresh the page with F5 and resend information, however if checked, image in the file is already different.
In Firefox, sometimes it works and image refreshes, sometimes not.
any help would be greatly appreciated!
cheers,
Simon

Hi Daverms,
With your code you suggest to not only upload the image but make a database entry too. However my intention is to firstly upload the file, and show a preview. Then if user is satisfied with what he sees, he presses "aprove" button and therefore makes a datase entry. Then the photo number will increase by one.
Until user is not aproving the photo he can upload any image again and again, but the new image will be always given the same name (example 4.jpg) and overwriting the old one.
I believe the problem persists because browsers are loading image with the same name from the cache, and not from the actual location. Therefore when I refresh the page it catches the correct image.
If I follow your code, every time I upload the image, name of it is different, therefore browser cannot find it in the cache and is forced to load one from the server.
I wonder is there any way to avoid this cache problem?
cheers,
Simon

No, using a servlet is the way to go.
