Problem regarding PDF printing in apex 3.1 and 11g database using cocoon

Hi,
i am configuring pdf printing on apex 3.1 (database 11g on windows XP OS) with cocoon/apache tomcat/fop using steps given in Carl Backstrom blog
http://carlback.blogspot.com/2007/03/apex-cocoon-pdf-and-more.html
I am using cocoon 2.2.10 / tomcat 6.0.20 and JDK 1.6
I did everything as was mentioned in Carl's blog and everything configured without any hassle. I even enabled network services for FLOWS_030100 user on database. Even after doing all the steps I'm getting the error
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
I'm confused and don't know what to do next.

Hi,
By default, the ability to interact with network services is disabled in Oracle Database 11g release 1 (11.1). Therefore, if running Oracle Application Express with Oracle Database 11g release 1 (11.1), use the new DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the FLOWS_030100 database user. Failing to grant these privileges results in issues with PDF/report printing, specifically, you will get the following error message:
ORA-20001: The printing engine could not be reached because either
the URL specified is incorrect or a proxy URL needs to be specified.
Follow the steps mentioned in the Oracle Application Express Installation Guide, [Enabling Network Services in Oracle Database11g|http://download.oracle.com/docs/cd/E10513_01/doc/install.310/e10496/post_inst.htm#BGEJJIHE]. Also refer to the [troubleshooting section|http://download.oracle.com/docs/cd/E10513_01/doc/install.310/e10496/post_inst.htm#BHAGIHIB] in case you receive an ORA-44416: Invalid ACL error after running the previous script.

Problem with pdf printing in Apex 3.2

Hi All,
I have apex 3.2 in Oracle 11.1, and the OS is OEL4. I ran the post installation script for granting connect privileges for APEX_030200 also.I have installed BI Publisher in another machine, and configured the URL in apex.
But the Pdf printing part is still failing.
when i open the pdf ,the Error is "Adobe Reader could not open 'Applications[1].pdf' because it is either not a supported file type or because the file has been damaged(for exmple, it was sent as an email attachment and wasn't correctly decoded)."
I tried to open the file using text edtor, the text inside is "ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified"
My apex machine is 64 bit and BI Publisher machine is 32 bit.
I ran the following query to verify that the grants were given:
SELECT * FROM DBA_NETWORK_ACL_PRIVILEGES;
The result of this query is the following:
ACL     ACLID     PRINCIPAL     PRIVILEGE     IS_GRANT     INVERT     START_DATE     END_DATE

Verify that the BI server is accessible from the 11g database by executing the SQL below in the 11g database
select utl_http.request('http://<bi_server_host>:<bi_server_port>/xmlpserver/convert') from dual;
The response returned should be something similar to

The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details.</PRE></BODY></HTML>

Apex 4.2.2 PDF Printing with Apex 2.0 Listener

We recently installed Apex 4.2 with the Apex 2.0 Listener and can successfully print interactive reports and classic reports to PDF. I viewed Mark Sewtz PDF Printing with Apex 4.2.2 and saw how he is using third party tools to format reports. We have also looked into the Jasper Report Integration Toolkit, but have only got it working on the Tomcat environment, not WebLogic.
I'm trying to download a classic report in PDF format with our logo displayed at the header. In the print attributes section, there is a section for header. I've tried adding the following in the header section:
<img src = "http://hr.unm.edu/common/images/unm_dept_logo.gif">
No Logo Prints
#APP_IMAGES#unm_dept_logo.gif
Prints in header:
wwv_flow_file_mgr.get_file?
p_security_group_id=3930016164431413%26p_flow_id=106%26p_fname=unm_dept_logo.gif
#WORKSPACE_IMAGES#unm_dept_logo.gif
Prints in header: /i/unm_dept_logo.gif
I've also added the logo in the report region, prior to the columns printing, but no logo downloads to PDF.
Does the Apex Listener only render text? Is there any way to get the logo to print in the header without using a third party tool? Any suggestions are greatly appreciated. Thanks!

Hi,
There are different options to include images in your PDF exports. What's important to understand though is that with the PDF export functionality we separate the formatting from the actual data. So the formatting is defined in your RTF or XSL-FO templates and the data is stored in the XML that APEX generates based on your report data. We have several formatting options exposed on the print attributes pages, i.e. you can define page formatting, dimensions, fonts, colors, etc - all of these are applied to what we call generic XSL-FO templates. Those templates are generic in that they can be used with different reports, having variable numbers of columns and variable column names. Those formatting attributes can not be used however with named column templates, such as those that you generate with BI Publisher or those third-party tools I talked about in my Blog.
So if you want to use these formatting options, you need a generic report layout - which you get out of the box using the built-in layout. But you also have the option to create your own generic report layout (see Shared Components -> Report Layouts). When creating a custom generic report layout, you'll get a copy of the built-in layout as a starting point. Once created, you can manually modify this layout to meet your needs. As you edit this template, you'll find a number of #....# substitution strings. This is what APEX uses at runtime to fill in your formatting values as well as to assemble your generic layout based on your result set.
Now one way to include your own image would be to add an image reference to this generic report layout. You can't use the page header or footer attributes on the print attributes page for that because the FOP rendering engine does not understand or translate HTML. It renders XSL-FO. So to add your own image reference, you need to use XSL-FO mark-up. If you want to add an image to your page header, look for the #PAGE_HEADER# substitution string in the "Page Template" attribute of your generic report layout. You should be able to find the following:
<fo:inline xsl:use-attribute-sets="page-header">
    #PAGE_HEADER#
</fo:inline>
Now assuming you have a file stored in your local images directory on localhost, you could add the following external graphic reference:
<fo:inline xsl:use-attribute-sets="page-header">
    <fo:external-graphic src="http://localhost:8080/i/cloud.gif" content-height="scale-to-fit" height="30px" content-width="150px" scaling="non-uniform"/>
    #PAGE_HEADER#
</fo:inline>
Once you're done with your chanages, save the report layout and edit your report. Go to the print attributes and select your generic report layout and then run your report page and export the PDF. Provided the APEX Listener is able to find this external image reference, it will now be included above your report in your PDF document.

Marc

Apex with XE10g/Tomcat 6.0.13 PDF Print with Apex FOP.WAR

Apex with XE10g/Tomcat 6.0.13 PDF Print with Apex fop.war/apex_fop.jsp
Hello,
Excuse me bad english.
I have a problem with Oracle XE and Printing from Reports over Tomcat 6.0.13.
I have update Oracle XE with Apex 3.1 and it works fine.
Now i have tried to Print a report to PDF. So i have deployed the FOP.WAR from Apex Utilities under Tomcat.
I see in Tomcat Manager http://localhost:8888/manager/html/list that the FOO
has been deployed and is running.
If i try to print then i get this Message down to this page.
Can anybody give me a hint to solve this problem???
Hint
To resolve the problem i have installed Oracle OC4J with same Port and deployed
the same foo.war file.
Then works and all printing from Oracle Apex work fine and okay.
So i thing the Apex and Oracle work correct.
But we have a small Application so i would prefer to work with Tomcat a application Server.
Becaus of previous Errors have copied some *.jar files to C:\tomcat6.0.13\lib
but i thing this is not the Problem.

Another problem with PDF printing

Hi all.
I try new pdf printing in Apex 3.0 with printing engine Apache FOP and BI Publisher. Both engines seems work well. I configured Apex engine to use Standard Support for pdf.
Next I imported example application http://www.oracle.com/technology/products/database/application_express/packaged_apps/pdf_demo.zip and run it. But when I press "print" link, instead pdf output I receive error page "404 Not Found The requested URL /pls/apex/f was not found on this server."
Apex 3.0 reside on Oracle 9.0.2 database server and use it http server with modplsql. Both Apache FOP and BI Publisher works on standalone OC4J container.
In Apex's http-server error log I noticed next error messages:
[Fri Apr 13 16:07:11 2007] [warn] mod_plsql: Stale Connection due to Oracle error 22293
[Fri Apr 13 16:07:11 2007] [error] mod_plsql: /pls/apex/f ORA-22293
ORA-22293: LOB already opened in the same transaction
Is anybody know what to do in this situation?

Problem with pdf-printing in Adobe Acrobat Pro

Hi,
I have Adobe Acrobat Pro 9.4.3.
PDF-printing has always worked great but suddenly there is some kind of problem.
After printing a excel-document from "Print to pdf" built-in function in MacOS OR Adobes Printer I have corruptet pdf-files when showing them in Adobe Reader/Acrobat, but the MacOS Preview-software shows them correct.
So, there cannot be any problem with the printing, but the local preview on my computer using Reader or Acrobat. I dont even use the Myriad font in the document, I use Verdana.

You say you're using Verdana but you're not. The error message clearly shows you're using MyriadPro Bold.
You probably recently installed the Mac OS X 10.6.7 update which has a bug with OpenType PostScript fonts like MyriadPro Bold. Either use Verdana or another TrueType or PostScript font, or revert to Mac OS X 10.6.6.

PDF Printing in APEX 3.0

Hello. I am working my way thru the PDF Printing in Application Express 3.0 document. I am currently stuck at step 5: Configure Oracle Application Express to use the JSP for PDF printing. When I access the Admin Services home page and select Manage Services, I cannot locate the Instance Settings, under the Manage Environment Settings. Is there an error in the documentation or am I just not in the right spot?
Thanks

Hi Denise,
That .cpio file is not a CD image file, it is actually an archive file containing the files and directory layout that you need to extract first. You can do that by using the (Linux/Unix) command cpio like this -
cpio -idmv < file.cpioNote that BI Publisher is an extra licensed option that you will need to make sure you're covered for.
As an alternative (and if you're willing to live without the 'Advanced' support that BIP provides), then you can use Apache FOP. Carl Backstrom made a fantastic video showing how to set this up, which you can find here -
http://carlback.blogspot.com/2007/03/apex-cocoon-pdf-and-more.html
APEX does not come with a built-in BI Publisher, I think you're thinking of the pre-supplied FOP configuration in APEX 3.0.1 (which makes it even easier to setup now).
If you haven't looked through it already, I can highly recommend the "PDF Printing in APEX" document available here -
http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html
Hope this helps,
John.

CUPS problems with PDF printing

I am having all manner of problems with PDF printing. Recently added a Lexmark MX710 and have 7 machines that were previously printing fine to an X652de a T652 as well as a Samsung CLP770. All network printers.
Now there are bizarre issues with PDF printing. CUPS version 1.6.1. The MX710 will blue screen and reboot when printing one specific pdf without fail. There are all kinds of random nonsensical results when printing from different locations. A pdf that stalls the X and T652 with "filter error" will print from my own machine to the same printer, using the same versions of cups, .ppd file, and everything package related to cups.
Yet other PDF files will print, while some print complete gibberish, I can't find any rhyme or reason or anything predictable about any of it other than to say printing postscript files works fine all around.
This has been universally in KDE printing through Okular.
I've tried some things I've found suggested, such as modifying the mime.conv as suggested by an old ubuntu thread, adding the a2ps package, all to zero effect.
Last edited by TheWretched (2012-12-08 00:27:41)

At this point the only reasonable explanation I can think of is that the ppd package I downloaded and installed via included shell script from lexmark for the mx710 caused this whole catastrophe. The only common thread for this problem starting was that I used this on all of the affected machines and they now all manifest problems. And on four of these machines this is literally all that was done, they were loaded in september, have not been updated via pacman in any way, and are running the exact same version of cups poppler, and okular that they were then, which was working, and now cannot print pdf to any printer at all without causing one of several problems depending on the printer.
I cannot seem to get this reversed though. I've gone so far as to force remove all the cups packages, and delete the files associated with the install script, but the problem remains afterward. From what I can see so far all this lexmark package did was display a license agreement, then copy the ppd files in it's folder to /usr/share/ppd/Lexmark. This particular printer, the mx710 has no .ppd available that I have found other than this one from Lexmark directly. Open printing doesn't have anything for this model.
This printer's driver has some kind of a cups filter driver with it that the install script presumably installs, I suspect this could be what caused the problem specifically, but I must not be removing it correctly, despite following the file removal suggestions in the Lexmark readme for uninstallation. CUPS printing is something I am new to and only have a basic understanding of.
To answer some specific questions I nearly forgot, I don't have cups pdf installed. I have chrome installed which can successfully save pages to PDF, previously it could also print pdf, and presumably it prints everything as pdf given the cups pdf workflow. That is also broken now too, so printing from the browser causes the printer to fail as well. If I save as pdf from chrome, and print with adobe reader, it works.

Canon pixma pro 9500 having problems with my print out. colors are glazed and missing colors

canon pixma pro 9500 having problems with my print out. colors are glazed and missing colors
i have prfiled the mac and printer wiht colormunki and uplodated the profile sucessfully
i set the printer to correct icc profile
print out comes out same with glazed colors and missing tones/colors
however when i use the same printer on windows and with light room, following same icc profile, colormunki calibrated profile, the print our are excellent.
i have also tried using printer manage profile using the Mac and Aperture and get same poor prints
can you please assist and thanks

I've a Pro9000 and also use Colormunki successfully.
When I use Colormunki, I calibrate both of my monitors and the printer/paper combination. Colormunki saves the generated profiles to the correct places -- I don't load or change any profiles after that as that would mess-up what the Colormunki had just done for me, and this would likely mess-up the prints.
Though I double-check the settings in the print dialogue, the choice for the printer handling things is already grayed-out. Colorsync handles it all just fine.

What program did you use to fix the internal hard drive? What repairs did it report making? More crucially, if repairs were reported, did you re-run the utility until it reported no problems found? It's possible for one set of problems with a drive to mask others.
If you have about 5GB or so free space on the internal hard drive, you can use your OS X Install disc to perform an Archive and Install to recover from the failed Software Update. When the computer restarts, download and run the OS X Update Combo 10.4.11 (Universal). When the Mac restarts after that, run Software Update. During all this, make sure nothing interrupts or shuts down the Mac! Note that the first start after each of these updates will take significantly longer than subsequent starts, so be very patient.
How did you back up your internal drive to the external one? Did you just drag things over in the Finder, or did you use a utility such as SuperDuper! or CarbonCopyCloner? Does the external HD show up as a bootable volume in System Preferences > Startup Disk, or using Startup Manager?

Printing messages in Log File and Output File using Dbms_output.put_line

I tried using a function to print messages and calling that function in my main package where ever there is fnd_file.put_line. But this approach is not required by the business.
So let me know how I can achieve this functionality.

PDF Printing from APEX 4.0

Hello
I have a requirement to create PDF reports from websites created using Apex and /or PL/SQL. The reports are a mixture of formatted text, pictures and charts.
Using BI is not an option due to the cost.
What do you recommend and where are I find simple instructions to follow (I lhave imited system / DBA skills).
Thanks for looking. All help very welcome
Regards, Pete

There are multiple options..
If you want a BETTER RESPONSE, please include the following information in your questions here:
Version of APEX?
App Server being used?
Browser being used?
Why this is important is, there are FREE plugins for APEX 4.x that will produce PDF's. There is also FOP which is included with APEX as a free print engine..
Thank you,

Acrobat 8.1.5 on Vista x64 problem with PDF Printer

Hi all
Forgive me if this is a newbie question... I *tried* to get direct support from Adobe and they spent the time telling me my support had "expired" rather than answer the question... nice... so thought maybe someone knows the answer.
I have the latest version of Acrobat 8 on Vista x64. Anytime I use the "Adobe PDF" printer to print direct to PDF from an application, the PDF gets produced OK, however the print spooler for this printer retains a print job with status "Error - Printing".
The only way I can remove the job is to do it manually and a lot of times I have to Cancel it twice for it to work.
Any ideas how I can stop this from happening?
Thanks
Steve

Thanks... will give that a try and report back...
Reporting back... nope it did not fix the problem. But the repair process did damage the install of Acronis True Image so that it wouldn't load... I did a Repair of that install too and at least now I am back to where I was...
Appreciate the help. Anyone else have other suggestions?

In APEX, first try using the default report layout (its ugly, but it will show at least if your query is producing xml data).
Can you build a small report in APEX, with one or two columns, and build the RTF layout in Word and upload it to you app, and try that as a test..
Next I would recommend looking at the apache logs to see if there are any errors occurring when APEX sends the xml stream to BI Publisher.
Also, have you posted this over in the APEX support forum? The developers of APEX are there and they WILL help you find an answer, Marc the product manger helped me with my BI Publisher/APEX issues..
