PDFGenerator/OCR fails if primary OCR language EN

I am trying to create and ocr a PDF from scanned invoice Nextra.tif with Primary OCR language setting different from English.
The scanned document Nextra.tif converts and ocrs fine in stand-alone Acrobat 8.1.1 Pro on any Primary OCR language settings.
When I try PDFGenerator in LiveCycle adminui and Primary OCR language in File Settings is EN, DE, FR, SP or IT everything works fine.
However, when I select language for example Polish, Croatian, Hungarian, … I just got error:
Error Code:16003
Error Message: ALC-PDG-016-003-An unknown/unexpected error occurred during PDF post-processing.
Here is the stacktrace as I found it in the log:

The second problem is that, the Primary OCR language I really need to set is Czech or Slovak, but LiveCycle offers only no existing Czechoslovakian language.
Is there way in LiveCycle PDFGenerator to convert and ocr a scanned document on Czech or Slovak language setting?
I installed the Adobe Acrobat 8.1.1 Pro and LiveCycle for JBoss using Turnkey + SP1b on Windows Server 2003.

hi Igor
did you solve this problem?
I met a same problem in Korean environment.
If you solved this problem, could you advice me how to solve it?
Thanks in advanced

SOS: javax.ejb.CreateException: Create failed because primary key is null

Hello,
I am desperately trying to get my application server to create a record through CMP 2. My app server is JRun 4.
Here is the client:
package com.parispano.tests;
import java.util.Date;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.parispano.account.entity.Account;

public class ClientEJBDeuxTemp {
public static void main(String[] args) {
    System.out.println("\nBegin account DemoClient...\n");
    try {
      // Create A Demo object, in the server
      // Note: the name of the class corresponds to the JNDI
      // property declared in the DeploymentDescriptor
      // From DeploymentDescriptor ...
      // beanHomeName demo.DemoHome
      Context ctx = getInitialContext();
      AccountHome ahome = (AccountHome) ctx.lookup("AccountEJBHome");
      //System.out.println("Creating Demo\n");
      Account account = ahome.create("toto","toto", "toto","toto","toto","toto","toto","toto","toto","toto","toto",new Date(),new Date());
    catch (Exception e) {
      System.out.println(":::::::::::::: Error :::::::::::::::::");
      e.printStackTrace();
    System.out.println("\nEnd DemoClient...\n");
static String user     = "admin";

   * Gets an initial context.

    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY, "jrun.naming.JRunContextFactory");
    p.put(Context.PROVIDER_URL, url);
    if (user != null) {
      System.out.println ("user: " + user);
      p.put(Context.SECURITY_PRINCIPAL, user);
      if (password == null)
        password = "";
      p.put(Context.SECURITY_CREDENTIALS, password);
    return new InitialContext(p);
}and here is the exception I get:
javax.ejb.CreateException: Create failed because primary key is null
I don't understand why I get this as the primary key is "toto" and therefore is not null.

Yes, I have set the PK. Actually this is happening when the number of columns are more than 63 columns. After I reduce the number of column, it is working fine.
Is it the actual problem???
fyi, I'm using jboss as the Application Server...

Primary & Secondary Languages?

Hi,
What is the differentce between primary and Secondary langues with inheritence and current langues?
Thanks In advance
Vijay

hi,
Primary & secondary languages:
Repository can be maintained in multiple languages. In the console we will define in how many languages repository is maintained ( 3 0r 4 languages), you can maintain N number of language layers. when ever you are logging into the repostory using language English, if it is not maintained it will be opened in other language in the order you maintained in the repository. we can compare the data in different languages, colour coding.
MDM multilingual support fully addresses all of the requirements for multiple languages side-by-side within a single MDM repository. It starts with an end-to-end Unicode implementation that supports both Western and Eastern languages, reflects a data model with multiple language layers that avoids data duplication while ensuring data
integrity, and features an innovative user interface that offers flexibility and efficiency during the entry, editing, browsing, and publishing of multilingual data.
An individual MDM repository can be defined as storing data for an effectively unlimited number of languages, chosen from a list of languages and locales recognized by the system (e.g. English [US] and English [UK]), including both western European and Eastern languages.

PDF Generator fails on Convert-OCR tif

Ok, so LC ES Preview up and kinda running (on XP SP2 Virtual PC, 2gb RAM)
Went to create PDF direct from LCPDFG UI (so, http://localhost:8080/adminui/... etc and a .tif converted fine to an image .pdf
However, when I chose opton 'File Type Settings - Standard OCR' I just got error msg:
'PDFGenerator Process Launcher has encountered aproblem... with ntdll.dll - pdfgen.exe mdmp and appcompat.txt mentioned.
The .tif converts and ocrs fine in stand-alone Acrobat 8 Pro.
p.s. - Error code: 1000 - error msg: ALC-PDF-001-000 Conversion failed because of an exception. RuntimeException:CausedByException is: An unexptected exception while resolving a new connection to an Adobe Service.

Hi Jess - ES is jut running on a virgin XP SP2 Virtual PC (2gb RAM dedicated) so no other processes should be accessing it.
One thing I wondered - for the ES Preview, you get a 30 day eval of Acrobat 8.1 Pro - which of course usually comes up with the 'this is an eval - do you want to buy/continue' I would not have thought it would have been included if a problem, but could that be it?
"Check to be sure the environment variables are set up correctly - this should be done automatically during installation and deployment."
- all the JDK stuff was checked and seemed fine.
Major problem is the vagueness of the LC error msg - any way to get more detailed error info??
Thanks

Use acrobat 8 in a shellscript and make a pdf file OCR recognize text with selected language

Hello everybody !
I have a little problem and I don't know how to overcome this...
I want to use a shellscript and call acrobat.exe and open a pdf file (up till now I've done this..), but the difficult part is that I want in this shellscript to use parameters/switches in order to make the pdf file OCR text recognized and use selected language e.g greek !!!!
How can i do that?
What is the command prompt parameters...?
In command line when i use
c:\> cd C:\Program Files\Adobe\Acrobat 8.0\Acrobat
C:\Program Files\Adobe\Acrobat 8.0\Acrobat> acrobat.exe <pdffile>
it opens the pdf file in the acrobat....
So what switches do I have to insert next?
Thanks a lot in advance !!!!

Microsoft has released a hot fix that supposedly addresses this issue, it is at
http://support.microsoft.com/kb/977468
I downloaded the fix and tried it; it actually made the problem worse! Apparently they
are trying to fix their filter rather than bypassing it. What I am doing is
1. Making maps in AutoCaD Map and printing (plotting in autocad) them to a pdf file
2. Opening the pdf file in Acrobat and resaving it as eps
3. Importing the eps file into a Word 2007 document
4. Use Acrobat to convert the Word document to pdf
Before the hot fix when I did the process the resolution of the map in the final
pdf file was not as good as in the original made from AutoCad. Also the colors were
not correct. After installing the hotfix there are still these same problems but also now
any non horizontal text is not displaying correctly.
Be careful about trying this hotfix.
As others have noted, back in Word 2003 the above steps 1 - 4 worked very well and resulted
in a high quality pdf file with the map as good as in the original pdf.

Hi,
have you setup SSH for the new node (for User Oracle) in both ways, when extending it?
A common problem is to extend SSH is to do this one way only.
However especially when extending the cluster, there are some oracle tools which ssh/scp to the existing nodes (as the installation owner) to copy special files (like ocr.loc) to the new node.
If SSH is not setup both ways, then this will fail.
Check with user oracle or grid (whatever you used) that
ssh <node1> date
ssh <node2> date
ssh <node3> date
ssh <node4> date
Is working (from every node).
Note: In 11.2 you can rerun root.sh. Just do a $CRS_HOME/crs/install/rootcrs.pl –deconfig –force to deconfigure the stack and then rerun root.sh

OCR fails - "Paper Capture recognition service" error

Hi all
I get this error message when trying to use Acrobat X Pro (10.1.4.38) OCR feature installed as part of CS6 Master Collection. I have reinstalled everything and AFAIK all the the other MC apps are working and updated properly. There doesn't seem to be a way to <just> uninstall/reinstall Acrobat on its own so I'm at a loss...
CS6 Master Collection, Win7 64bit Intel i7 12GB ram, no other apps running.

I would start with an update, not a reinstall. The update can be done either from the Help>repair in Acrobat or by going to the Programs & Preferences in the Control Panel and running it there. If you succeed in the repair, then run the updates (again from the Help>Updates) or download the updates from http://www.adobe.com/support/downloads/product.jsp?product=1&platform=Windows and install them in order. However, it appears you have the updates, so the repair is what I would try.
If you do a reinstall, then I would also run the cleaner utility that Adobe provides for Acrobat. The URL is posted in several of the discussions on this forum.

Cm:getProperty tag fails for Primary property (SP2)

I was successfully using the following tag with SP1:
<cm:getProperty id="node" name="html" isMultiple="false" conversionType="html"
/>
Since installing SP2 this now fails.
It works fine for non-primary properties.
If I add the failOnError="true" attribute I get the following stack trace (I've
truncated the stack trace, let me know if you want the whole thing):

Try using the transactionTimeout attribute, that corrected things for me.

Exchange 2013 Auto Attendant fails when using multiple languages

Hi All,
Trying to setup UM Auto Attendants as I had it in Exchange 2010, but cannot get it to work as I want.
Here is my setup:
Windows 2012 and Exchange 2013.
Parent - Main Auto Attendant (80)
Child - English Auto Attendant (81)
Child - Swedish Auto Attendant (82)
Child - Finnish Auto Attendant (83)
All callers are first connected to 80 where they can select the language to continue with (press 81 for English, press 82 for Swedish, press 83 for Finnish).
This is what I found out this far:
- If I have English language selected on all Attendants everything works fine I can select all choices and everything works as it should.
- If I select the proper language for the other languages (82 & 83) only the connection to 80 & 81 works. If I try to connect from 80 to 82 or 83 nothing happens (connection goes quiet) and the only solution to get UM to answer again is to restart the
UM service on the server.
Extra info/what I tested this far:
- I reinstalled the extra language packs just to be sure there were no issues.
- If I select Swedish or Finnish language on extension 80 they work fine, so the language packs seems to be OK.
Ideas Anyone?

Hi All,
After installing CU1 for Exchange 2013 this behaviour changed a little bit. Instead of getting total freeze of the system I get an error message instead saying "System Error Occured" and then a hangup.
I also find out that if I remove the checkbox "Set the auto attendant to respond to voice commands" for the extension 82 & 83 (Swedish & Finnish Auto Attendants) this error does not happen, but I like to use the voice commands....
Also when the error occurs I get the following in the Event Log:

OCR resulting in Grainy Images and junk OCRd Data

Why is OCRing not working on my PDF? I have two PDFs produced by two different Tiff to PDF tools. Both produce seemingly good PDFs that Acrobat reader has no problem rendering. The process we use to OCR the PDF is to load it into Adobe Acrobat X and to run an action that has a single step - Recognize Text (using OCR). The Primary OCR Language is English (US) and the PDF Output Style is Searchable Image. The PDF from the old tool can be OCRd in Adobe Acrobat X without any problems (the image looks good and the OCRd text is suitable). It appears that Adobe deskews the images automatically. The PDF from the new tool cannot be OCRd in Adobe Acrobat X without incurring some problems (the image looks grainy, and the OCRd text is junk). It appears that Adobe DOES NOT deskew the images automatically. To overcome the grainyness of using this second tool, we've attempted to turn on the PDF Output Style of "Searchable Image (Exact)". This overcomes the grainyness issue, but doesn't help with the junk OCRd text at all.

Here's a copy of some sample PDFs (one from each of the two processes/tools)

The file size for the old tool is smaller than that of the new tool.

Recognize / OCR Thai pdf in Acrobat Pro 10.1.9

I have wasted an hour trying to install a language pack and change my installation but have failed.
I am not even sure it is possible on this version of Acrobat but I want Thai as a Primary OCR Language setting in order to recognize the text in a scanned PDF. Please help?
Kind regards
John

Thanks for your response.
So Acrobat Pro can recognize certain languages (Hebrew, Chinese etc) and these are configured during the installation process but there are no 'language packs' I can install to OCR Thai?
Any suggestions how one might recognise the text in order for it to be copied and pasted etc?

Any option to invoke OCR tool from a keyboard only without mouse

As surprising as it may sound, I could not find any option to run from keyboard a command to start OCR (Optical character recognition) operation for the current document.
Many (actually the most) in operations commands Adobe Acrobat Professional XI can be run with a keyboard hotkey (shortcut) and/or via main menu accelerator keys, say, as a command "Create PDF from file" with a hotkey Ctrl+N or keyboard accelerators Alt+F -> R -> F.
So if you your mouse fails to work or you can not use a mouse due to some accessibility issues, you can however run the most commands using the keyboard only.
But I could not find any way to start OCR recogniizing operation using keyboard only, neverthless how long serie of key pressing you are ready to fulfill. Well, you can use accelerators Alt+V(iew) -> T(ools) -> T(ext Recognition) in order to open Tools sidebar at the left edge of the window - and than?.. Seems, that there is no option to get a focus to this vertical toolbar without mouse.
As I can not use my mouse just now, it is a real headache for me Is there any solution?
Thanks in advance!

@ CtDave
I'm afraid, that you have missed the most important part of my clarification. Your advice will not help, if somebody (not necessarily you, but rather the previous owner of the document) has already recognized it - but only in some part. Say, the command/hotkey Ctrl+A will not help, if the document has only 1 recognized page from 100 pages, what is a quite probable situation.
Ctrl+A will not help too, if the document is already recognized, but with wrong charset and/or output style and/or resolution - and you need to re-OCR it with correct settings.
I do not see, how your additional explanations of which OCR settings are correct, could help in such situation.
So Ctrl+A (Select all) command is a workaround for some very restricted situations.
To have a consistent OCR workflow simply set the PDF Output Style to Searchable Image (Exact).
Usually I prefer the option [Searchable Image]. Do you think, that [Exact] is generally better?
There is no user configuration/choice of 'charset' consequently this is not a viable concern.
Hm... Have you ever put attention to the dialog Recognize Text, including the very 1st line in the [Settings] field, that is [Primary OCR Language]. And the the button [Edit...] with the proper language settings as well (please look at my screenshot here: http://img691.imageshack.us/img691/9172/k56.gif
As one can suggest, when you select the primary OCR language, it also involves the charset too, because, say, English, French and China languages charsets are quite different.

Acrobat 9 crashes on OCR

I've been trying to convert a batch of large PDF files to PDF searchable files by using the OCR of Acrobat. In the middle of a batch, a large (1000+ page) document crashes acrobat. I have narrowed it down to this image:
http://img90.imageshack.us/img90/2418/badke2.png
59,520 bytes
When I convert it to PDF (File->Create PDF->From Single File) and then use Acrobat to "Document->OCR Text Recognize->Recognize Text using OCR", Acrobat always crashes.
Is this true for anyone else that could try it?
It kills my batch processing and is making this large conversion quite painful. Is there a way around it?

MacBook Pro (1997)
- Mac OS X 10.7.2
- 2.6GHz Core 2 Duo
- 4GB RAM
Acrobat 9 Pro
- version 9.4.6
Acrobat 9 Pro OCR always crashes when using ClearScan but not when using "Searchable Image" or "Searchable Image (Exact)." I scanned several journal pages at 300 dpi (color, grayscale, bitmap) in .tiff and .png as well as screen selecting text from a browser. The results were consistent across all variations.
The last time I used the Acrobat's OCR function was last Summer before upgrading from Snow Leopard to Lion. Under Snow Leopard, Acrobat did not crash during OCR (it did crash, just not while processing text for OCR). I did not attempt Acrobat OCR under Lion 10.7 or 10.7.1.
Repeatable test.
1. Open wikipedia "Crash (Computing)" page
http://en.wikipedia.org/wiki/Crash_(computing)
2. Enlarge text size, if desired.
I tried several text sizes from the default to much, much larger. Text size has no impact on the results.
3. Create a PDF
File >> Create PDF >> From Selection Capture
I selected the first paragraph:
A crash (or system crash) in computing is a condition where a computer or a program, either an application or part of the operating system, ceases to function properly, often exiting after encountering errors. Often the offending program may appear to freeze or hang until a crash reporting service documents details of the crash. If the program is a critical part of the operating system kernel, the entire computer may crash. This is different from a hang or freeze where the application or OS continues to run without obvious response to input.

OCR Acrobat 9

I’d like to ask you some questions on the use of Acrobat 9 Professional:
- When the OCR is performed, is it possible to choose the font to use as reference, as in the case of the choice of the language?
- Done the OCR Image Only, how is it possible to correct the hidden text?
- Why in some pages it is impossible to effect the OCR getting the message "the page contains text which can be submitted to rendering?"
You can give me some sources which I can consult; in the guide I haven’t found any answers.
Many tanks

It's strange that while I posted to this Adobe forum, there is a response over at objectmix.com. As contributing to this topic from 2 locations seems confusing, I'll carry on here.
Amannagpal76 responded, saying in part that ClearScan in 9 Pro replaces Formatted Text & Graphics. Good to know this. ClearScan does, however, continue the mix. If ocr doesn't work on a character graphic, that graphic will continue to be displayed as such, amidst ClearScan's synthesized type 3 font imitation of the original font. This is most obvious when using the marquee zoom tool.
Aman suggests using the Touchup Text Tool and changing the font to any font installed on one's system. This doesn't work for ClearScan. Selecting a different font in Touchup for a PDF that came via a wordprocessor works fine, but not for a PDF that came via a scan. That, unfortunately, is the only time that ClearScan is used. The error message when I try this states that there's no system font to match the one in ClearScan, and text can't be added or deleted.
ClearScan is remarkable for the small size file it produces. That size can be reduced considerably even further by converting it to the Adobe 7 file format. ClearScan's synthesized font is also remarkable when enlarging the page on screen. Then you can see its true outlines -- rather chewed up in high magnification, but that's OK. It would be nice to extract the font in question and use it on one's system. One downside to ClearScan is that its ocr fails to retain italics when output to RTF and Word.
I have never found a suspect in 9 Pro.
The conclusion from the above is that the hidden text produced by any ocr'ing in 9 Pro can't be corrected.
