PDF Printing with FOP/Apache Tomcat/J4LFOPServer in windows

Hi everyone,
I have been learning to create pdf report with Apex 4.2 and BI Publisher 10 which I have been successful with. Now I like to learn how to create pdf reports using FOP thinking of the customers who will not spend money on BI Publisher. I have gone through the documents and procedures described in Java 4 Less. http://www.java4less.com/apache/fop.php and http://www.java4less.com/fopdesigner/fodesigner.php?info=apex. Configured Apex instance setting accordingly.
For default layout a tabular pdf report is created.
I have created an xsl-fo file named Formatted_report.fo on same query and xml file from report query with BI Desktop. But when I try to print a formatted output with Formatted_report.fo report layout it does not work(J4LFOPServer ). but same layout with .rtf template works fine (BI Publisher Print Server).
Please help

hi,
if you use the J4lFOPServer as you write, you can set it in debug mode as described here:
http://www.java4less.com/apache/fop.php?info=faq#debug
you will then see the XML data and the FO data in the server window. Maybe you can see there if there is an error and that can help you fixing it.

PDF printing with oc4j apache fop not working

I am configuring PDF printing in Apex 3.1.1. I have set up a shared component report query with a simple query. I have implemented the oc4j standalone and implemented the fop.war as specified in the "pdf printing in Apex" documentation. When I use the test button to verify the output of the report, I am redirected to a 404-page not found and the oc4j instance logs the following:

Hello,
Just did some more search on this, and apparently it's a more common problem:

Hi!
I am trying to get this solution working on a LINUX system using TOMCAT 6.0.18 rather than OC4J which we don't have a license for. I have tried both FOP 0.94 and 0.95 and seem to get similar problems. Here is the error message:

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.

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

After searching against this error i found that the length should be lower than 32k.

So, what reason throws this error ?
Any ideas ?

no not yet with Application Server.
I have tried to compare the settings to another installation with a separeted oc4j as described in the howto. But at the moment i found no mistakes.
If i call the url adresse like:
http://localhost:18101/fop/apex_fop.jsp
i get:
500 Internal Server Error
Servlet error: java.lang.ClassNotFoundException: fop.apex__fop
I installed it another time with these settings:
Web Anwendung= .../fop.war (selected war file from apex install directory)
Anwendungsname= fop
URL zuordnen= /fop
I would like to know if its possible to use the fop.war out of apex install directory with the Application server? In the standalone version (as described in howto) it works. But if you install it there you don't need to define an URL.
Is the URL /fop correct or what do i have to insert there?

PDF Printing with XSL-FO and Apache FOP

Can anyone show me in the right direction for this? I've been hitting a wall for the past 2 weeks or so and it's really starting to infuriate me. How am I supposed to work this out? Where do I start? Let's say I create a layout file with a WYSIWYG XSL editor, in what format do I export it? XSL, XSLT or XSL-FO? I figured it was XSL-FO, but who knows. I tried them all anyways, but nothing seems to work. I seem to be missing a step or something, 'cause something's definitely not right.
I created a report query (which actually contains two queries):

Best regards,

Hello Mathieu
i assume that the default PDF printing is working, but that you want to create some better looking reports and therefore use a different non-generic XSL-FO.
You can do several things in Apex but you can use the Apache-Fop conversion also indepent from Apex.
What you need is:
1) An XML (Data) File. You can get it from your report query when you say export it to XML.
2) The XSL-FO (Layout) file. THis is the processing instruction that says how convert the XML Data into an XML-FO. You can create it manually or with some tool.
3) The next step is to render the XML-FO into any output format (pdf, rtf, html)
The creation of the XML-FO and of the PDF are done by the apache fop converter (cocoon or Batik framework if I remember correctly) in a single process but you can influence it so that both steps are done separately. See also: http://xmlgraphics.apache.org/fop/0.95/running.html
The advantage is that you usually get much better error messages from the single steps.
My recommendation would be to do all the steps with a very basic report first.
Then gradually improve the complexity of the report, the data and the layout.

Problems with FOP/Apache - Apex PDF printing

Hello,
I have configured
Apex 3.0.1
iAS 10.1.3.x (http + modplsql)
OC4J 10.1.3.3 (stand alone)
FOP for PDF printing
RDBMS 9.2.0.8 64bits (Solaris)
following the OTN recipee and this setup does not seem to work for all cases.
For instance, using the Apex admin interface, I go to the monitoring page :
Home -> Monitor Page -> Login Attempts
And click on the Print link (left bottom corner of the page) , it works o.k, the PDF is generated correctly.
However, if I go to
Home -> utilities -> Object Reports -> Table Storage Sizes
and click on the Print link, it does not work. A pdf file is generated with the following text
<HTML><HEAD><TITLE>500 Internal Server Error</TITLE></HEAD>
<BODY><H1>500 Internal Server Error</H1>
<PRE>Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details.</PRE>
</BODY>
</HTML>
If I check in the application log I see the following error
07/08/08 11:52:21.584 fop: Servlet error

I do not think it is related to a config/installation issue. It seems a parsing issue with the SQL stmt being executed, but it works for some SQL code and not for other.
Some users did notice this problem this morning when testing the new PDF printing.
Any ideas ?

Help with error (apache tomcat + java )

hi all ! Im having an issue with my program.
Im using jasper report to generate some reports from the program... everything seems to work except for this (making the program unstable at some point). When the report is generated and loaded as a pdf I get this error in the log.

The code Im using to generate the pdf is this one.
File file = new File("C:\\Reportes\\", reporte +""+ datNac +".pdf");
String contentType = getServletContext().getMimeType(reporte+ "" +datNac+ ".pdf");
System.out.println("antes BufferedOutputStream");
BufferedOutputStream output = null;
output = new BufferedOutputStream(response.getOutputStream());
BufferedInputStream inputFile = null;
inputFile = new BufferedInputStream(new FileInputStream(file));
response.reset();
response.setContentType(contentType);
response.setContentLength((int) file.length());
response.setHeader("Content-disposition",
"attachment; filename=\"" +file.getName()+ "\"");
System.out.println("BufferedOutputStream");
byte[] buffer = new byte[10240];
for (int length; (length = inputFile.read(buffer)) != -1;) {
output.write(buffer, 0, length);
inputFile.close();
output.close();Any help is appreciated.
Thanks!

response.reset();At least you should obtain the outputstream AFTER the reset. If that doesn't fix, then check everything in the chain before this code.

PDF Printing with images

Hello all-
I was wondering if it is possible to create a PDF document with images from a report that has images, through the FOP. I have tried this on APEX 3.2.1 and APEX 4.0.1, but with no success. I installed FOP in a standalone OC4J that I have installed on my PC and this works fine. I am using the Demonstration Application to test creating the PDF with images by trying to print page 23 - it is a report with images. I get a PDF report, but the image column is blank - no image, no errors. Has anyone been able to accomplish this?
Thanks in advance,
Greg

Hi,
yes you can, this tool allows you to create FOP templates with images (look at the examples)
http://www.java4less.com/fopdesigner/fodesigner.php?info=guide
You can of course create your own FOP templates without this tool, there is a XSL-FO tag to do that, you must make sure the images are available to the print server, either by referencing images on the file system or deploying the images in the print server.

PDF printing with proxy server

Hello,
I installed Apex 3.0.1 and configured it for pdf printing using OC4J and Apache FOP. The OC4J process is running on the same server as the database. I used localhost as hostname and 8888 as port.
Everything works fine, however, when I specify a proxy server in the Application Definition, the pdf printing stops working ... I suppose this is because the print server is now located through the proxy server and this doesn't work ... But, I need to configure the proxy server because I want to use an external web service ...
Anyone else that has this problem and knows of a possible workaround ?
Thanks
Matthias

Well, in my case this is not an option, since I used a demo host and domain name which can't be resolved through the proxy server ... If only there was an option to skip the proxy server for localhost settings (like there is in Internet Explorer).

PDF printing with APEX version 3.2.1 and OAS 10.1.2.3

Hello,
Is it possible to print PDF's with APEX version 3.2.1 and OAS 10.1.2.3? (Not using freeware- that'll never fly with my company).
Thanks!

JasperReports will do this and there is an integration toolkit out there for it and APEX.
BI Publisher is available, and costly
Oracle Reports can do this and is still available..
One question, why would your company shy away from open source software like Cocoon/FOP? It comes with APEX 3.2 as an installable WAR and if you use the APEX listener, it comes with that for FREE!!
Thank you,

SVG in pdf created with FOP

Hello,
is it possible to include SVG`s to a pdf report, which is created with FOP?
I read something like Batik....
Does anybody have any experiences about that?
Thanks,
Tim

Thank you, CtDave, for your speedy reply and for the 'Acrobat Technical Evangelist' knowledge base article. Word 2000 is one of Microsoft's masterpieces - by disabling 'autosave', the application is totally stable, does not require 'activation' by Microsoft. Acrobat 9 enables 'saving' of interactive .pdf forms, a most valuable feature and one much appreciated by anyone completiing such forms. There must be more to this issue than 'incompatibility', because I can create a test Word 2000 document, hyperlink a valid URL, convert to .pdf with Acrobat 9, and the hyperlink works fine in Acrobat 9. When I attempt to do this using a much more complex Word 2000 document, embedded with scores of hyperlinks, these links fail to work following conversion to .pdf with Acrobat 9, but work fine following conversion to .pdf with Acrobat 6. I can then use Acrobat 9 to open the .pdf created with Acrobat 6, and successfully edit any of these fully functional hyperlinks using the 'Link tool'. I don't know who prepared the 'Acrobat Technical Evangelist' article (AF1908DCd01) - no credits were cited, and I'm far from certain that this authentically belongs to Adobe's knowledge base. So I appreciate your sharing this information with me, but I cannot say that my question has been definitively answered. If you have any further information or tips, please reply in this thread. /rmbrown
