FOP problems...

Hi,
I have the following problem. I have an J2EE application that i am starting from Jdeveloper at the embeded OC4J . When an transformation to PDF is called from a servlet in pdf transformer class responsible for transformation there is a call of:
org.apache.fop.apps.Driver fopDriver = new Driver();
I receive the following exception:
java.lang.IllegalArgumentException: org.apache.fop.svg.SVGElementMapping is not an ElementMapping at org.apache.fop.apps.Driver.addElementMapping(Driver.java:464) at org.apache.fop.apps.Driver.setupDefaultMappings(Driver.java:314) at org.apache.fop.apps.Driver.<init>(Driver.java:222) at bg.vies.business.artifactexport.service.transformer.impl.FOPArtifactTransformer.initializeDriver(FOPArtifactTransformer.java:70)
etc.
I am tried to put all libs from fop distribution first in <JDEV_HOME>\j2ee\home\applib and then in <JDEV_HOME>\BC4J\lib but without any success.
Any ideas....i think it is from class loading...
Thank you in advance!

Hi,
yes it is in my classpath.
Let me explain in more detail the situation. I have a separate Java project in my workspace that is responsible for processing transformations. It is as a framework for performing transformations. Let's name it FOP_project.
I have a Web project that depends on FOP_project so I explicitly mark this in project properties as dependecy (Web depends at FOP_project). As you say in the article in FOP_project I set all fop libs, but as one fop-0.20.5 lib where I have added all libs of fop-0.20.5.
When I ran Web project from JDev and transformation was invoked java.lang.NoClassDefFoundError was thrown for fop.jar and avalon-framework-cvs-20020806.jar, so in order to bypass this NoClassDefFoundError problem I put fop.jar and avalon-framework-cvs-20020806.jar in <JDEV_HOME>\BC4J\lib.
And then I receive:
java.lang.IllegalArgumentException: org.apache.fop.svg.SVGElementMapping is not an ElementMapping at org.apache.fop.apps.Driver.addElementMapping(Driver.java:464)
etc.
Do you know what is wrong?
Thank you!

Apache FOP Problem with column width

We are using Apache FOP to generate simple pdf documents out of reports.
My problem is that the table in the pdf is as standard filled in with columns of same length.
Further on the content of some table fields is to large or sometimes there is to much room.
is there any possiblity to let fop react like html?
The smallest table field size should be like the content. I don't want to adjust all my reports, cause there are really many reports with pdf printing.
anyone an idea how to solve this with FOP?
i have no BI pubisher or other reporting engines for this problem
thx so far

Oliver,
I think what you're looking for is having your column width automatically adjusted based on the content of your column values. That is not possible with the built-in, generic XSL-FO template. What you can do is manually adjusting the column width to appropriate values on the print attributes page.

Marc

XML TO PDF printing

Hi,
I managed to create a pdf File, from a XML document, using XSLT and XSL-FO.
I'd like now to print this pdf File from my Java application. Is there a simple way of doing this ?

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.

Problem of FOP memory with APEX ...

Hello everyone !!!!
I installed FOP in Oracle Applications Server, and said ApEx to use FOP to generate PDF files.
However, the memory of FOP is very limited because it can't create PDF files if there are more than about 1.200 lines in the Report I want to print.
I found on the net there was something to do for this :
- launch the JVM with "java -Xmx1G" to use a memory of 1Go
- create FOP_OPTS="-Xmx1G"in the file $HOME/.foprc
But the file doesn't exist, and I don't access to any JVM ...
Could anyone help me to know what to do ????
Thanks by advance,
Pierre C.

Hi Varad,
I tried your solution, however it didn't function :
I found the opmn.xml file and changed the java-option for the OC4J contener of my application, setting it to "... -Xms512m -Xmx512m".
Then I tried to print a PDF Report with about 1.700 lines, but the file was "corrupted", but with 1.300 lines it's ok.
I also tried the Metalink note 744866.1.
Is there any other think to do in order to solve this problem ??
Thanks by advance,
Pierre C.

Problem in IAS Server with generation of PDF with FOP and XML parsing

Dear co.forumers :
We are developing an application that generates a pdf document with FOP Apache utilities, and this PDf is stored in a folder of the server. Firts of all, a DDBB data is retrieved using java ( jdbc) middleware classes ( servlets ), and with these data, the pdf is generated using FOP. In these process, he data retrieved from the DDBB is converted in a XML file , and the with the XSL FOP utility, the pdf is generated.
In the other hand, we have another application that consults data from a java beans, using a JSP, generates a XML with the data of the beans, and with this XML, and with a XSL file generates and html , with the data and fixed text.
Both applications have been deployed as a separated WebApp in the IAS. Both use Xalan as XML parser amb Xerces is used aswell.
So, the problem is , after generating a pdf with the firts application, every html generated via JSP-XML-XSL transformation in the second application is shown completelly bad formated. All fixed text are wrongly composed, and the text that should appear in textFields and ComboBoxes is also bad formated. The XML with the data is well generated, so the problem is in the parsing of these XML and the conversion in html through XSL. We have to re-initiate the server and then everything goes well again. If no pdf is launched, no problem occurs with the other application.
How an a WEB APP pplication can affect to another, installed both in different folders of the IAS ? We tried to change Xalan version and FOP version, but no result.
Is this a Poltergeist ?? and X file , maybe ?
Has anyone had the same problem ?
Pleae, any help will be very wellcomed.

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

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 ?

Apache FOP getClassLoader problem

I have loaded Apache FOP 1.1 into an 11g database, and a driver class to retrieve XML/XSLT and save PDF as CLOBs. When I try to execute this in the DB, I get
ORA-29532: Java call terminated by uncaught Java exception: javax.xml.transform.TransformerException: java.security.AccessControlException: the Permission (java.lang.RuntimePermission getClassLoader) has not been granted to ProtectionDomain (null <no signer certificates>)

It looks like the SecurityManager is only looking at PUBLIC permissions, even though the FOP classes were loaded into a schema with 'SYS:java.lang.RuntimePermission', 'getClassLoader', ''.
Any ideas on how to get around this?
Thanks!

Dear Brian,
It looks to me like org.apache.fop.apps.Driver might be doing a
Class.forName() for the Loggable class. If Class.forName() does not pass a
specific classloader, the system classpath loader is used; which is why it
works when you put the classes on the system classpath.

Apache fop classloading problem in EAR file

HI,
I am deploying a big EAR in WL 6.1 on solaris and I am bundling FOP 1.20.3
within it, I am
also including avalon 4.0 and logkit 1.0 jars within it as they are needed by
fop.jar. Whenever I
try to construct a "Driver()" class I get a NoClassDefFoundError on the org.apache.framework.logger.Loggable
interface that it needs. The strange thing is that when I do the following :
try {
ClassLoader cl = this.getClass().getClassLoader();
cl.loadClass("org.apache.avalon.framework.logger.Loggable"); // .........this
works OK
// the following .... fails with NoClassDefFoundError on Loggable
org.apache.fop.apps.Driver d = new org.apache.fop.apps.Driver();
} catch (Throwable t) {
cat.error("failed:", t);

Dear Brian,
It looks to me like org.apache.fop.apps.Driver might be doing a
Class.forName() for the Loggable class. If Class.forName() does not pass a
specific classloader, the system classpath loader is used; which is why it
works when you put the classes on the system classpath.

Problems with FOP

Hello everybody,
I have some problems with FOP...
I want to create pdf outputs and I want to use FOP to convert reports into pdf`s.
The documentation says that you have to install OC4J, but I can`t find the directorys to unzip the FOP files!
I installed the OC4J standalone version...
It is wrong?
What should I install? J2EE?
Sorry, but I am new at this topic...
I hope you would help me!
Thanks,
Tim

Kevin,
quote from the FOP homepage ( http://xmlgraphics.apache.org/fop/ ):
FOP (Formatting Objects Processor) is the world's first print formatter driven by XSL formatting objects (XSL-FO) and the world's first output independent formatter. It is a Java application that reads a formatting object (FO) tree and renders the resulting pages to a specified output. Output formats currently supported include PDF, PCL, PS, SVG, XML (area tree representation), Print, AWT, MIF and TXT. The primary output target is PDF.
FOP (Formatting Objects Processor) is basically a mechanism to transform an XML stream of data (e.g. the pure data of a page rendered using HTML DB) into an arbitrary output format, i.e. PDF.

FOP and XSQL problem

Hi All
I am using XDK 10 and FOP 20.5, see my previous post - it all works fine.
However I have found a weird thing and that is that the .xsql file is executed twice when using FOP, but only once when using a normal XSLT stylesheet.
Anyone else noticed that?
TIA
Richard

I figured out the problem. The version of Acrobat Reader 6.0 that I am using seems to load the document again if it does not display properly the first time round. I have got XSQL file caching on, but I disabled caching on my browser. This effectively overrides the XSQL file caching of the xsql servlet.

Richard

FOP file size problem

Hi,
I need to generate a pdf file from a .fo file. The problem is that I'm running out of memory when trying to use a .fo file of 2.5Mb. It isn't a small source file, but I was expecting to work.
Here's my configuration: WindowsNt on a sytem K6/500Mz, 160Mb RAM.
I've serched the Apache bug database and indeed, this is a known problem, but the reports out there indicated problems of source file over 40Mb which is kind of far from my situation.
Anyway, I want to know if there people who successfully generated pdf files out of source files larger that mine.
If I would have to change on using FOP, what java product could I use
instead?
Thanks a lot

Hi Friends,
I am facing same problem while generating PDF from XML, XSL-FO and using SAX parser. My XSL-FO size is 3.5MB.
I tried couple of approaches for generating PDF, first directly converting XML to PDF, second converting XML to XSL-FO and XSL-FO to PDF. Both approaches gives me "Out of Memory Error".
I would highly appreciate if someone can post some sample code or give me some info, on how to solve the problem.
Thanks

Cocoon-FOP Output Problem

Hi, I'm trying to implement Carl Backstrom's Tomcat-Cocoon-FOP solution.
I know its probably a Coccoon/FOP issue... when I click "Test Report" I get the following (see below).
I haven't edited anything :), and i'm just trying to output one field from a table as a test (no empty fields).
Oh ya... and the PDF that won't display?? ...Is actually HTML output.
Is there a hidden problem of stream definition/assignment/error handling lurking in the background as well?
Anybody seen this one before?
javax.xml.transform.TransformerException: attribute-set named #TEXT_ALIGN# does not exist
cocoon://fop_post/xsl - 148:58
Cocoon stacktrace[hide]
attribute-set named #TEXT_ALIGN# does not exist

Ok then... paying attention always works doesn't it? As he takes another (closer) at the tutorial video... :)
I've been trying to do a test report via:
Home > Application Builder > Application # > Shared Components > Report Queries
...and I get the above error. But when I plug it into an for real app it works like magic. Kool, PDF's to die for! Thanx.
Bit of a problem with printing to Word docs tho...
Word says "Missing file: C:\cocoon\styles\main.css", and a bunch of the usual bafflegab.
Am looking for the reference to "c:\cocoon\..." to figure out how to change it, but haven't found it yet.

Cocoon/FOP + form-name problem

Experts,
I have configured Tomcat/Cocoon to work with APEX instead of BI Publisher, as per Carl Backstrom's tutorial. Tomcat and Cocoon both work as expected. I am able to configure APEX with the correct URL, port, and Print Server Script, standard support, and so on.
I am able to use FOP to process static XML files with no problems.
If I understand how APEX works with Cocoon, it generates a Form POST to send an XML document to Cocoon for processing. Cocoon receives the posted form. Cocoon extracts the XML data based on the name of the posted form, and then transforms it into the specified format (PDF, RTF, HTML, etc.). In Carl's tutorial, Cocoon is configured in sitemap.xmap to expect form-name="xml".
Question: When APEX executes the Form POST, what form name does it give the posted form? Is this configurable?
Whenever I try running an APEX report through Cocoon/FOP, I get
org.apache.cocoon.ProcessingException: Unknown request object encountered named xml : null.
I have tried renaming form-name to wwv_flow, wwvFlowForm, XML, Xml, asdf,<null>, etc. Whatever I rename the form shows up as null.
Examples:
1. org.apache.cocoon.ProcessingException: Unknown request object encountered named wwv_flow : null.
2. org.apache.cocoon.ProcessingException: Unknown request object encountered named wwvFlowForm : null.
3. org.apache.cocoon.ProcessingException: Unknown request object encountered named asdf : null.
4. org.apache.cocoon.ProcessingException: Unknown request object encountered named xml : null.

Hi Carl
I use Tomcat and Cocoon as you described. For some reports PDF print is OK. One problem which i found was that, in my case, the language of the application produce also an error. I changed from German to English and everything was OK.
"Application > Shared Components > Edit Globalization Attributes > Globalization" - Aplication primary language GERMAN. Once that i changed to english US my reports worked again OK.
I have also an application where for one page PDF produced is OK but for another page in the same application i receive the same error:
org.apache.cocoon.ProcessingException: Unknown request object encountered named xml : null.
Maybe Region configuration is different?
Best regards
Adrian
