Create multiple pdf files and open them at once from java application

I came across a very unique problem , i am hoping some one could help me out with that .
I am using itext to create pdf files , i have filtered some records (preferably i can say around 90) which has the option to open pdf for individual record.
Now i need to open all the pdf's of filtered records on a single click , without asking for a open dialogue box.
Can anyone give me an idea how to go about this ??

The simplest thing I can think of is to call Desktop.start() for each selected file wich will start the defaut application registred for the file type in the users system for each selected file. In this case it depends on the associated program and/or its configuration if it starts a single instance showing all the files or a separate instance for each file. The beauty of this method is that you don't need to know what reader application the user has installed nor where it is located on her hard disk.
The other option that comes to my mind is ProcessBuilder. There you could set all selected files as parameter list to the call of the viewer application.
This also does not asure that all files get openned in the same single instance but the chance is much higher. At the down side you need to know what viewer application the user has installed and where. Also: when speaking of 90 files you most likely rung into a limitation of the maximum length of the systems command line.

Export to PDF - Can a single report (rpt file) create multiple PDF files using the export command?

Post Author: markeyjd2
CA Forum: Exporting
Greetings forum members,
My question is, in its entirety: Can a single report (rpt file) create multiple PDF files using the export command, ideally one PDF file per DB record?
In my case; I have a Crystal Report that reads data from a DB table containing ~ 500 records. When I export the report to a PDF file, I get one PDF file, with ~ 500 pages.
What I would like to do is export the report to ~ 500 individual PDF files; One file per DB record. The file names would be based on the table's primary key.
Is this possible?

Hi,
you need some lines of code, but its easy. Dependend on how to start the generation of your 500 PDFs, you can write an ASP page and start it via Web Browser, or a Windows Script and start it via scheduled job...
Here's an abstract of the ASP code I use:
First, you create a recordset (here: "rsc") which gives you the list of ID fields you want to export, then you create CrystalRuntime.Application object, then you loop through the recordset, open your report (here: "oRpt") and set login info. Then set the selectionformula, so that the report displays only the data of the current ID, e.g.:
oRpt.RecordSelectionFormula = "(" & oRpt.RecordSelectionFormula & ") AND {myTab.myVal}=" & rsc("myVal")
Then you export the report, move to the next record in recordset, and repeat the loop until recordset.EOF. Then you close recordset and connection.

These are the "out of the box" file formats that you can view on the iPad as mail attachments. If the file is not listed here, you cannot view it without a compatible third party app. What is the file extension?

Give the physical path to the filename. You have write
permission for this folder to create a PDF file.

I am having problems creating PDF file and downloading them

I am having problems creating PDF file and downloading them

Hi Randy Keil,
You might need to sign up with your Adobe ID and password at "https://cloud.acrobat.com/convertpdf"
Then you can choose the desired files to create the PDF.
Now, let me know what error message do you get while doing the same.
What kind of files are you trying to convert to PDF?
Have you checked with your internet connection and tried using a different browser?
Hope to get your response.

How to create multiple pdf Files out of multiple pages documents??

I wrote multiple pages documents and stored them in a directory. That is nice, but now I want to transfer them all into pdf files.
Is there a way to do this or do I have to open them one by one an select "Print" and so on??

Pages 5 has virtually no AppleScript support so it would be difficult to even make an Automator workflow to do what you want.
So yes you will have to make a pdf of each one. Be warned that Pages 5 stuffs up links after the first pages of pdfs.
Apple has removed almost 100 features from Pages 5 and added many bugs.
http://www.freeforum101.com/iworktipsntrick/viewforum.php?f=22&sid=3527487677f0c 6fa05b6297cd00f8eb9&mforum=iworktipsntrick
Pages '09 should still be in your Applications/iWork folder if you had it previously.
Archive/trash Pages 5, after Exporting your files to Pages '09, and rate/review it in the App Store, then get back to work.

How is it possible to download my Word Perf files and open them on my Ipad 2?

Is there a way to download my Word Perfect files to my Ipad 2 and open them? Is there an app that would open them?

Well (James)... WordPerfect is a central theme of this thread.
Nut that aside, I have to say, I belong to many, many, forums, and this is by far the most negative exchange I've had in long, long, time. I would not have thought that thinking outside the box was beyond an Apple forum.
You guys are big thinkers, right?
I'm just looking to help my users do their jobs better.
Yes, like it or not, iPads are now in the work-force and we do weird things out there in the world.
A lot of lawyers use Word Perfect. Don't ask why.
A lot of lawyers are beginning to use iPads. We all know why.
My simple aim was to help them see their documents as easily as they can a PDF.
Maybe too lofty a goal...
Maybe not.
And yes, Corel should have some skin in this game too.
Check out the threads on this same subject on Corel's forum.
All-in-all this exchange has been personally exhausting and ultimately unfruitful...
Thanks.

How can I create multiple PDF files from multiple InDesign files?

I have 144 InDesign files that I need to create a PDF file for each. I do not want to open each InDesign file to create the PDF's. Acrobat Batch create won't open the InDesign files. Is there another way?

Only InDesign can do this. You may want to look at InDesign automation.

Create multiple pdf files from html pages

I have 15 html pages that I need to convert (possibly several times a day) into pdf files, and I need to get the process as automated as possible. I own an Acrobat Pro 8 license.
1) is there a command line I can launch to do this automatically?
2) failing that, is there a way of launching several conversions at a time? There seems to be lot of talk about creating one pdf from several files, but what I want is to convert several html file into several pdf files
thanks

Managed it at last, was a bit of a hassle -
(there was an erroneous error message saying I hadn't selected any files, when I had)
Note For future readers: to do just a batch conversion, you have to ignore the "commands" section, which isn't intuitive, as it is bang in the middle and looks like the main feature...

I haven't looked closely, but my spidey sense tingles at this:
new FileOutputStream(MPath)This will clobber (erase) the previous contents of the file. Open in append mode:
new FileOutputStream(MPath, true)Of course, if the file exists before you run this code, you will end up append to the original contents. If that is not wanted, consider using File's delete method first.

How to create multiple pdf files from multiple batch processing

I have several file folders of jpeg images that I need to convert to separate multi-page pdf files. To give a visual explanation:
Folder 1 (contains 100 jpeg image files) converted to File 1 pdf (100 pages; 1 file)
Folder 2 (contains 100 jpeg image files) converted to File 2 pdf (100 pages; 1 file)
and so on.
I know I can convert each folder's content as a batch process, but I can only figure out how to do so one folder at a time. Is it at all possible to convert multiple folders (containing jpegs) to multiple pdf files? Put differently, does anyone know how to process a batch of folders into multiple (corresponding) pdf files?
Many thanks.

There are two approaches to do this:
- First convert all JPG files to PDF files using a "blank" batch process. Then combine all PDF files in the same folder using another batch process and a folder-level script (to do the actual combining). I have developed this tool in the past and it's available here:
http://try67.blogspot.com/2010/10/acrobat-batch-combine-all-files-in.html
- The othe option is to do everything in a single process, but that requires an application outside of Acrobat, which I'm currently developing.
If you're interested in any of these tools, feel free to contact me personally.
