Performance problems to generate PDF files using CR

Hi,
I develop an application that read TXT files and uses this information to generate PDF files, but I'm having problems with performance to generate this PDF, each files are taking at least 1 minute to create the file. I realized that some TMP and RPT files are generated and deleted in the temp folder of the machine which is running the application, but after some time creating the PDF's the RPT files aren't deleted and I have an exception on my app:
Memory full.
Failed to export the report.
Not enough memory for operation.    at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext)
   at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.FormatEngine.ExportToStream(ExportRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.FormatEngine.Export(ExportRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.ExportToDisk(ExportFormatType formatType, String fileName)
The server who is running this application is a Dual Core AMD Opteron 2.61 ghz, 7 GB RAM
The framework version is 2.0 and the Crystal Reports dll version is 10.5.3700.0
Thanks.

Hi,
If you are using IIS5 the give aspnet full permission to the Temp folders. For IIS6 give IIS_wpg permission.
For this you need to right click on the folder,
go to properties,
security tab,
click on Add,
Type aspnet/iis_wpg,
select top note in Location and click on check on check names.
Give full control and
click ok.
Also try using GC.Collect(), reportDocObject.Close() and reportDocObject.Dispose() as clean up code.
Regards,
AG.

Problems reading generated pdf-files

Hi all,
I have problems reading generated pdf-files from
Report Builder 6.0.8.11.3
An error-message occurs when opening the pdf with
Adobe Acrobat 5.0.1:
... problem 110 and after moving in an empty pdf-document
the messages:
- too few operands
- an unrecognized token
I think the solution must be very simple, but the docu and
other info resources provide nothing aboutthis issue.
Greetings,
Bernhard

hello,
there are no known problems with reading reports PDFs with later Acrobat Readers. maybe your file is somehow corrupt.

I had to install a local printer, the network printer is not appropriate here. After that, everything is fine :-)),

Generating PDF file using FOP API in Web Dynpro

Hi experts,
I would like to generate PDF files from a WebDynpro application without using Adobe Interactive forms.
I think that I can export context data to XML stream and then apply XSLT transformation to produce XSLFO format and then pass it to xlfo processor i.e FOP to generate the PDF file.
Has someone already try this way of generating PDF files?
Is it a good way of processing ?
Thanks in advance.
Thomas.

hi Thomas,
You can make use of the iText API to create pdf documents through webdynpro.
For this you'll have to download the Itext api jar file.
Right click your webdynpro project include this jar file using the 'add external jar files'.Now you'll be able to make use of this api in your webdynpro project.
http://javaboutique.internet.com/tutorials/iText/ .
The above link will help you in using iText API.
hope this one helps you.
Regards,
Rahul.

Problem in opening PDF files using Reader 8 when created with iText 2.1.3

We are facing problem in using IText version 2.1.3. We are using Acrobat Reader 8.1 for viewing the PDF documents. In our Shell program we are splitting and merging the pdf documents using IText. The pdf document works correctly and is readable for documents with one page while it fails for documents with multiple pages.Also please note that it works fine with the older Arcobat reader version say version 7.0 and below but since business has migrated to acrobat higher version we expect IText to work in sync.
We have already raised a bug with the iText and got the information from them stating that the problem is due to the over nesting of XObjects, which has a threshold value of 50 and was discarded in earlier versions but got flagged in Acrobad Reader 8. Also note that we have reported a bug with the adobe development team.
We tried working with other Java PDF tools (jPDFProces), to manupulate the pdf files but were facing the same problem. Hence we understand that the problem is with Adobe Reader 8 as the manupulated pages are being viewed in Adobe Reader 7, but fails to read in Adobe Reader 8.
Kindly provide us with a solution.
Thanks and Regards,

Problem in upload PDF file using Apache HttpClient3.1

Hi:
I am using Apache HttpClient 3.1 to upload pdf image from a STANDALONE java application to remote server (Weblogic9.1). Here are some questions:
1) Do i have to use multipartpost method? (I am uploading pdf image one by one)
2) The pdf image is added to request as:
HttpClient client = new HttpClient();
PostMethod method = new PostMethod("myServletUrl");
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));
InputStreamRequestEntity entity = new InputStreamRequestEntity(new FileInputStream(file), "application/pdf");
method.setRequestEntity(entity);
method.setRequestHeader("Content-type", entity.getContentType());
int statusCode = client.executeMethod(method);
3) On server side, a servlet will save the posted pdf image as (Apache FileUpload is not used here):
InputStream is = req.getInputStream();
saveFile(is, fileName); // write this input stream to file.
The above steps 2 and 3 will create a pdf file on remote server with MUCH REDUCED size. Any idea what's the problem? content-type problem?
4) An working example link will be great.
thanks

Dunno, but as this is a client side issue, the solution, if there is one will lie in the HTML / javaScript.
If you dont get an answer in here, have google for an HTML solution, which you can then write out in your jsp.

Generated pdf file from oracle reports show bad characters

Hello all,
Iam fighting with a problem with generated pdf file from oracle reports which show some bad characters. I was searching for some information but it didnt help...
I have Oracle Database 11g R2 (or 10g R2) on Oracle Linux or Windows, Oracle forms and reports 6i (i know that is very old and not supported with 11gr2 but we are in this scenario).
NLS parameters are set like this
server:
NLS_CHARACTERSET EE8MSWIN1250
NLS_TERRITORY AMERICA
NLS_LANGUAGE AMERICAN
client:
NLS_CHARACTERSET EE8MSWIN1250
NLS_TERRITORY SLOVAK
NLS_LANGUAGE SLOVAKIA
When I run Oracle Reports it show perfect in display and when I try to print them, they are all good with good characters, but when I try to generate pdf file, some characters like č,š,ľ are not displaying corectly... This happen only when try to generate to pdf...
I try to work with uifont.ali on client side but without any result. Fonts for reports were installed on client and server side... Can someone help me with this problem? Thank you very much for every advice.
Martin

Hi Sergiusz,
Thank you for your reply. I look at what you wrote and try to make some test...
1) For first I download FontForge, which can generate type1 font from true type. So I open FontForge and open my Arial.ttf font and use "Generate Fonts" to save my Arial.ttf font to pfb and pfm (whoch are need to set in uifont.ali). I have to change encoding, because my font has 2byte encoding so I reecondode the font from ISO10646-1 to ISO8859-2 and generate to pfb.
2) Then I navigate REPORTS_PATH from regedit to my *.pfm and *.pfb files.
3) I add these lines to end of my uifont.ali
[ PDF:Embed ]
Arial = "Arial.pfm Arial.pfb"
ArialNarrow = "ArialNarrow.pfm ArialNarrow.pfb"
4) Then I generate my report but nothing change... I check "Font used" in my pdf file, but there were not my fonts embedded I guess..
I also try PDF:Subset, but it doesnt change anything... I try PDF aliasing to see if my uifont is working - this work very well, but I dont need to change font...
Any other advice? Thank you so much to everyone!

When trying to generate pdf file from firefox 7.0.1 , getting corrupt content error, used to work with previous versions of firefox

We have done toleration testing on firefox version 5 thru 6 and haven't got an issue with our website generating pdf files for our users. One of our users upgraded to firefox version 7.0.1 and they tried to generate a pdf report, now a screen pops up with Corrupted Content Error The page you are trying to view cannot be shown because an error in the data transmission was detected. I recreated this issue on my pc yesterday by installing firefox 7.0.1. Any hints as to what I need to look at would help. Cannot provide the url because it is a secure website for law enforcement. Thanks.

You can turn off compatibility checking, but more and more of the Google Toolbar will not work. Google is no longer supporting the Google Toolbar so you should use the alternatives.

regarding report, there is a dedicated report forum. you should post there.
but answer for your question is form is nothing to do with the pdf generation. you can call the report from the as usual.
In the report you should set the properties like
destype to 'file'
desname to 'path with file name'
desformat to 'pdf'

Problem reopening and/or refreshing PDF files using Acrobat Reader V. 8.0

I upgraded to Adobe Acrobat Reader V. 8.0 and have encountered problems refreshing PDF files in the Safari 2.0.4 browser when I am logged into the secure area for Value Line Publishing. Some of the PDF Files in this area can be opened and/or refreshed multiple times. Other PDF files in this area allow me to open them once. I cannot reopen those previously viewed files (or refresh the screen) -- after refreshing, the window changes to a blank white screen, and the files do not reopen.
I am perplexed because I do not have difficulty refreshing the PDF files (within Safari) using the native PDF viewer, I did not have problems refreshing files using Acrobat Reader V. 7.0 and I do not appear to have problems refreshing PDF files using Acrobat Reader V. 8.0 when I am outside the secure area or on other web sites.
I have replaced the Acrobat Reader plug-in, manually removed all remnants of previous versions of Acrobat Reader and reinstalled V. 8.0. and I also upgraded from Mac OS 10.4.8 to 10.4 9, all to no avail.
I can clear the Safari cache files as a temporary solution, but I encounter the same difficulties with the “problematic” files once they have been opened again.
I can also download the PDF files to my hard drive and refresh them multiple times within Safari and also using Acrobat Reader V. 8.0
The software personnel at Value Line Publishing have investigated their system and have referred me back to Apple. Has anyone heard of similar problems associated with Adobe Acrobat Reader V. 8.0 used in conjunction with Safari 2.0.4?
PowerBook G4 Mac OS X (10.3.9)

Hi Rodney
Welcome to Apple Discussions
This sounds like one of those "oddities", contributed to by a few sources.
I can clear the Safari cache files as a temporary solution, but I encounter the same difficulties with the “problematic” files once they have been opened again.
Wondering if you disabled the Safari Cache would the refresh function work correctly? As a test you can disable the Safari Cache by Emptying the Cache first via the Safari menu, then Quit Safari. Now go to the Finder>Your User Library>Caches>Safari. Single click on the Safari folder, then Apple Key + I to open Info panel. There, check the "locked" box. This prevents further additions to the cache. The downside, you lose your ability to upload images etc. within Safari (my cache is disabled, so I use Firefox for the uploads).
Then restart Safari. Try the PDF from within Safari.
