PDF generation : FileNotFoundException problem

Hi all,
I'm developing a dynamic PDF generation module in web application using iText framework. This module creates PDF on the server side then sends it to the client. Sometimes, Even though the PDF file is created on the hard disk, I got FileNotFoundException when calling the servlet that sends it.
My program is very simple (no thread used) :
1- The client calls enters some inputs,
2 - The iText based class generates the PDF,
3 - The PDF created is saved as an attribute in the client session (HttpSession).
4 - The request is redirected to servlet that sends the PDF.
What could be the problem ?
thx,

In fact, I don't know what you mean by:
3 - The PDF created is saved as an attribute in the client session (HttpSession).What do you mean by this? Did you save the proprietry PDF object? Or the java.io.File object? If it is the PDF object, does its class implement java.io.Serializable?
Um ... Here are some suggestions ...
First of all, make sure that the file really exists there.
Secondly, try to write a Java SE program to read the file using the absolute path you provided.
Then, if the Java SE program works, I think the reason may be that you haven't closed the "OutputStream" which writes the PDF file, or the security settings of your JSPServer prevents you from getting the file.

PDF Generation has problems

Hi there,
Our company uses Colffusion to make PDFs for our client.
Recently, the PDF generation is incredible instable, causing
corrupt PDF files or performance issues.
I found out, that the problem lies within the including some
picture. This slows down almost everything or sometimes the
generation does not happen at all.
Is there a solution for this? Is there a hot fix for that?
Thanks for your reply

Try <cfreport> instead of <cfdocument> which give
better results for these type of pdf conversion and image
issues...

APEX 4.1 - APACHE FOP PDF generation problem.

Hi all,
I'm having problem with PDF generation using APACH FOP on OC4J.
When I test my print server as described here:
http://marcsewtz.blogspot.com/2008/06/heres-another-posting-on-pdf-printing.html
everything works without problem. But when I upload my Layout to APEX and try to generate PDF from apex I'm getting error:

I could see similar post here:
Handling Special characters in call to apex_util.download_print_document
But it doesn't explain my case as it's crashing even when I generate empty pdf(no data so no special characters, only empty XML file with no data should be sent to print server)
Is there any way to see what xml is sent do print server for processing? That could eventually show where is a problem.
Palo

My mistake, there was really an "&" character in my template. now when I replaced it with %26 it works.
However I would be still interested if there is a way to see what data is APEX engine sending to print server cause it will help me to find this kind of errors.

Help: PDF Generation Problems in Reports 3.0

Hi Techies,
We are generating PDFs from Oracle Reports 3.0
The PDF generation is fine in some datbases.
But in some database,when the records are more, during PDF
generation, Dr.Watson error is encountered, saying access
violation.
Can any one please clarify whether the error is due to memory
constraints on the system or if it has something to do with
Oracle Reports setting, while generating PDFs.
Do note that the reports are running fine, when the report has
less number of records.
Any suggestion/tip is awaited at the earliest.
Thanks in advance,
Geoff

Very slow PDF generation when conditional text is hidden in FM 9.0

I am working on 96-page chapter of a larger book. A 7-page section of the chapter needs to be hidden until the next release, so I hid it with conditional text. After doing this, the "Save as PDF" printing process goes from taking 6-7 seconds to taking several minutes. If I unhide the conditional text in the same session, printing is very quick again.
I have no problem generating very PDF files with the PDF printer in other applications (Word, PowerPoint). The issue is specific to FrameMaker and the use of conditional text. What might be causing this?
I am using FrameMaker 9.0p255 and Distiller 9.0.
- Chris

Hi Jeff,
These were good suggestions to try. Saving the document first has no effect on PDF generation.
However, I did find that printing to the Adobe PDF printer remains fast when the conditional text is hidden. That's quite an interesting finding! I did also notice that these two methods of PDF generation aren't identical:
"Save as PDF" opens an Adobe Distiller window, while printing to the Adobe PDF printer opens a different "Creating Adobe PDF" progress box (looks like it's from the printer driver itself).
"Save as PDF" generates a 1188k PDF file, while printing to the Adobe PDF printer generates a 1049k PDF file.
"Save as PDF" defaults to placing the PDF in FrameMaker's working directory, while printing to the Adobe PDF printer defaults to saving to the last place to saved a printed PDF file (awkward when working with multiple directories, as I often do).
When I do a "Save as PDF", FrameMaker does still spool to the PDF printer. It is this spooling that takes a long time. Once spooling is complete, then the Distiller window opens and the PDF is created very quickly.
I would still like to get "Save as PDF" working since it knows where to place the PDF file. No solution to the runtime yet, but at least there is progress...

PDF generation with FOP throws NPE

Hi,
Stack trace
at oracle.xml.jaxp.JXTransformer.reportXSLException(JXTransformer.java:769)
at oracle.xml.jaxp.JXTransformer.transform(JXTransformer.java:342)
I'm using standard Java 1.4 API calls to create a PDF document from a DOM with Apache FOP 0.20.5.
The servlet is deployed to Oracle 10g Application Server 9.0.4.0.0. With Tomcat 4.1.30 the same code executes without exceptions
Because I have to port our web application to Oracle for a new customer it is important for me to get this fixed soon.
Thank you
Eckard

Light at the end of the tunnel: It seems to work when FO and PDF generation are separated. Until now the DOM was piped into FOP who internally created the FO from SAX events and then seems to parse it again to create PDF.
I separated the two steps: There is no problem in FO generation, but due to a namespace problem subsequent parsing fails
("org.apache.fop.apps.FOPException: null:2:10 Root element is missing the namespace declaration: http://www.w3.org/1999/XSL/Format")
Now the correct exception comes up. Whether FOP SAX event listener is buggy or XML parser's error handling has a problem, I don't know
Thank you anyway

CFDOCUMENT PDF generation peformance on Linux running CF server 8 or 9 is horrible

Can anyone help me understand how I can get the <cfdocument> tag to generate PDFs in reasonable time (and without throwing timeout errors) when running on CF 8 on Linux? Running on CF 9 doesn't make a difference, either. I can run the same code that generates a PDF on a Win 7 system and it completes the 1-2 page PDF in seconds. Do the same thing in CF8/9 on Linux and it takes so long (minutes) and then throws a timeout error. When we tried using Railo instead of CF8/9 it ran fine as well.

Our apps guy figured out the problem after googling the error log message. To put this in context, the deployed app is running in a Tomcat container on Linux.
The root cause is Java's AWT thinking there should be an Xserver available to talk to. Somehow in the code interactions during the PDF generation, calls are made to an Xserver that doesn't exist, with an absurdly long timeout. Adding the line "-Djava.awt.headless=true" to the catalina.sh script has solved the issue.
Hope this helps others!

BI 7.0 Web PDF Generation

Hi folks,
I do have a severe problem with PDF generation and it looks like a common issue.
I integrated Button to convert my Management Webreport to PDF, no big issue so far.
But the generated PDF is not bevaing like expected. We do have a BI report that contains 3 charts horizontally alligned by a table to fit the screen and 1 table below
those charts.
This report fits perfectly on one page landscape.
When generating PDF locally (PDF generator installed on client PC) Internetexplorer ==>PDF works as expected.
When using the Button in Webtemplate to use the BI functionality to export to PDF the PDF is a mess.
All template items are displayed in sequence taht means instead of 3 horizontal charts I see 3 charts and 1 table underneath each other.
It looks like the old fashioned 3.x print function.
My question:
Is there a way to influence the PDF generation. Maybe a class ( like former 3.x Table Interface) to modify to render the PDF like the template appearance?
We cannot install PDF clients locally nor can we ship management those reports coming from BI. Report designer is no alternative because of missing functionality.
TIA
Joerg

Thanks so far,
currently when using the container item and referring by command wizard ( export to PDF) the system is not generating any item.
Error Message 'file has no page and can't be opened...' occurs.
I think this is a really urgent Development issue because I think printing via PDF is getting more and more important since not everyone is using IE7 ( which is not fully supported by SAP either) to scale pages for printing.
Best regards
Joerg

Truncation in PDF generation

PDF generation via iBots produces only the first 8 pages. Last 4 pages are missing. At the end, it says 'Records 1 - 250'. This problem is not there when I generate pdf from Answers directly. Any clues as to where I should be looking?
Best Regards,
Dinesh.

Hi Dinesh,
I suspect that the <DefaultRowsDisplayedInDelivery> tag in the instanceconfig.xml got reverted or, is set to 250. Please review Note 530222.1 in MOS for more information on how to modifiy the value.

PS to PDF generation character missing

Hi
We have used 3b2 centralized server, each and every user will access the server and generating the ps files. While doing this ps to pdf generation, some time the character missing. Again we do make the same ps to pdf the text is there.
Because of this we are facing lot of problems. Could you please look into this matter as a matter of urgency.
Thanks in advance.

If you are having them print a PS file to the server and using Acrobat (or Distiller) for the conversion, you should read the EULA. Acrobat is not licensed for use on a server (including Distiller). For server use you should be looking at the Distiller Server.
In terms of the problems, they should probably be embedded the fonts in their PS files if the server does not have the fonts they are using.

Hi ,
There is an option of embedding index for faster search while converting email to a PDF .
However I am not sure that will serve your purpose or not .
I would recommend you to get in touch with Microsoft support as well .
Meanwhile I'll work on it and get back to you in case I get a desired solution .

I created a publisher file, saved it as a pdf. The problem is I created it landscape and it only shows portrait cutting the sides off my document.

I created a publisher file, saved it as a pdf. The problem is I created it landscape and it only shows portrait cutting the sides off my document.

Sounds as if you used Microsoft software to make a PDF. If so, and you didn't use Adobe Acrobat ($$), then you need to get help with Publisher -- Adobe Reader only shows what you make.

PDF generation in SDK

All,
I have some reports, whose PDF generation doesn't satisfy our requirements. A simple BO report page with a few sections.. ends up as a multiple page PDF. I had tried to also use the report/section properties as creatively as possible too.
I would like to get some information about if some-one has done PDF generation using SDK and if that provides more feature-rich formatting options?
Would appreciate your comments and advice.
Regards

Let's start with what version of CR / BO you are working with.
What SPs have you applied?
What version of .NET do you want to work with? What SDK do you want to work with (CR, RAS, BO)?
Are you doing these exports in the CR designer? - If so, have you consulted with the CR Design team on best way to design these reports? Typically, if you can not do something in the desinger, you more than likely can not do it from code either...

PDF generation on APEX applications Reports

Hi all
PDF generation on APEX applications is Facilitated in Interactive Reports in the Down load Option,
When we Choose this pdf Down load Option,this is not Working.
why this is not Working?
But this Down load Facility in Interactive Reports is Working fine with Excel Format
Do we need to Install & configure FOP/Cocoon or BI Publisher to Enable PDF Format DOWNLOAD
OR
any Other Work around Availble for this
please Suggest
tahnks Alot

To generate PDF file from APEX reports, you either have to install & configure Bi Publisher or FOP/Cocoon..

There are alternatives (jasper reports, pl/pdf), but they are also items you need to install and configure..
