CFIndex PDF files stored in the DB?

Hi all,
Is it possible to index PDF content stored as BLOB in the database, using the CF Search mechanism?
We are using the Solr engine right now, and for query based fulltext search it works like a charm, but I couldn't figure out how to do full text search for PDFs stored in the DB.
We don't have too many documents yet, under 1000, so I guess if all else fails, I *could* still write them out to a temp dir and do the indexing, and then do some custom linking to the DB code instead of the temp file, but that looks really dirty to me.
Any tips and advices will be appreciated!
Thanks in advance!
ZHU, Jia

I don't run into this problem because I don't store PDF documents in the databse. I just store the path in the database, and leave the document in a directory.

Opening pdf files stored on server

Hi
We have an application in which we display pdf files stored on the server.
Pdf files opens in a new browser.
User selects the invoice number from a list and based on the invoice selected, we get a pdf file from R/3 system. This file is stored in a particular folder on the server. We extract this file from the folder to show it to the user in a separate browser.
This functionality works fine in the development system but not in test system.
We have recently installed our test system and have done all required settings in config tool.
Config Tool --> Display configuration --> HttpHttps --> Root and Alias folder.
But despite this the functionality is not working.
Is there some other setting that I have missed.
Unfortunately these settings were done in the dev system by someone else and I do not have a document for it.
Can anyone help me please.
This is very urgent for me as we are plannning to migrate our production system as well. I may face the same problem over there as well.
Regards
Vineet

You may be able to do something with Oracle Text. The following shows how to get an HTML rendiditon of a binary document. I think you can also get plain text instead of HTML

Best ways to view/display PDF/Excel files stored in the Database

What are best ways to display/view PDF/Excel files stored in the Database? thanks L

Thanks tom, sorry let me explain. Currently we have oracle forms screen, using webutil to store/view files into DB. client won't like the interface, they want us to make it more friendly, drag and drop if possible, load multiple files, as possible.. So I am exploring different ways to improve may be java (or jdev/any any other), different screen designs, different features for fileupload/download/view options.

Oracle reports to display PDF/Excel files stored in the Database

can we use Oracle reports to view/display PDF/Excel files stored in the Database? Thanks Lalitha

A document stored in the database can be easily retrieved in or via the browser using mod_plsql. Simplified:
select content, mime_type
into v_blob, v_mime_type
from ...
owa_util.mime_header(nvl(v_mimetype,'application/octet'),false);
htp.p('Content-length: ' || dbms_lob.getlength(v_blob));
owa_util.http_header_close;
wpg_docload.download_file(v_blob);So, the link in your report should point to this database procedure.

How can i display a pdf file stored in my KM from webdynpro link ?

Hi experts,
i try to open my pdf file stored in km, in the same window of my webdynpro java who has the fire link ?
i user tow iviews with inBound and outBound plug, the first one has the fire link and the seconde an iframe witch i set source parameter to my km link where my PDF is stored. Unfortunately, the iFrame don't work correctly, and my PDF is not be displayed
Can you give some advices ?

Hi
Recently in my project I came across a scenario where my Web Dynpro Project had to pick the image from KM. The images to be displayed will be placed in KM. This will avoid loading the images into the Web DynPro project. More over when you have KM installed on your EP server, one can use it for storing backend data and resources. The KM Admin will be undertaking this task of uploading the images to predefined folder structures. Through the application path to the image will be provided dynamically giving you the flexibility to decide which image to be displayed according to the business logic.

Do you sync with iTunes and are the PDF files in your iTunes library? If they are, sync the iPad with iTunes.

Read pdf files stored in icloud drive from ios8

Ok. So how do I Access and read my PDF files stored in icloud drive from my ipad?
I´ve read that there´s no icloud drive App like dropbox and that it has to be done from a third party App. (strange enough), but I can´t seem to find a third party App that connects to icloud drive yet.
Thanks.

The Apple website specifically states "Because with iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images and any other kind of document in iCloud and access them from your iPhone, iPad, iPod touch, Mac or PC.".
Now, howe do I "store my PDF" and "access them from my iPhone"?

I am using Adobe Acrobat 9 Standard version in Windows 8.1 and when I try to create a .pdf file, I receive the following error message "Acrobat could not open "file name.log" because it is either not a supported file type or because the file has been damaged. To create a PDF document, go to the source application then print the document to .pdf" I am going to the source application and printing the document to .pdf yet it's saving the file as a .log file. After reinstalling the software, I initially didn't encounter this problem but on my second and third attempts to convert files to .pdf format, this error message reappeared. How do I resolve this problem?

I have a similar problem which i did not have before...and it exists only in some powerpoint files which i want to print as a pdf file...and i get the same message as above.
the log says the bellow details...what's the problem and how can i resolve it? thanks.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

To retrieve the PRT document (a PDF file) and insert the doc in PM order

Hello guys,
I have a challenging task in from printing as follows,
By using TC: IW3D we get print preview of PM Order Set (PM Print Program: YIPRJT01), currently the PRT document number prints in the PM Order. Now we have to insert the PRT documents (a PDF file) into the PM Order set rather than printing the PRT document number ( By using TC: IW33 by going OPERTIONAL TAB we will get the PRT document(a PDF file))
The requirement is to retrieve the PRT document (a PDF file) and insert the document in PM order set with out navigating separately by using the TC: IW33.
If you run the script in the print preview we can able to see PM the order set along with the PRT document (a PDF file).
Thanks & Regards
Vishnu

I'm also trying to print PRT document with shop papers and still not able to do so. I selected "P" for print on the control key and it should print but still didn't print.
If I understand it right, I think you are trying to do the same.
Have you resolved this issue ?
Thank you,
Sam
