FOP hangs after XML error
Hello. I'm running FOP 0.20.1 on a W2K PC. If there is an error in the input XML, FOP displays the error and hangs. I have to press Ctrl-C to stop it. This has never bothered me before, but now I'm running FOP many times in batch during the night and I don't want it to stop if one of the XML files is wrong. I've looked in the source-code to try and fix this, but there is something I don't understand: If there is an error in the input XSL, FOP behaves differently: it displays the error and stops. This happens in the XSLTInputHandler class, in the getParser method, at line 109: throw new FOPException(ex). I compare this code with the code the generates the exception when the input XML is wrong: Driver class, render method, line 461: throw new FOPException(e). These two lines are exactly the same; why does FOP behave differently? Thanks, Mike - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Design Tasks
Hi All, These are the design tasks that I think we need to cover before (serious) coding is done on the new layout approach. FO Objects: The classes that represent the FO object heirarchy should implement one or more interfaces that represent what the object can do in terms of the layout and what it will add into the layout. An fo object can create an inline or a block area or return what its children create. Layout Managers: Areas that create a page or block area will need to implement a layout manager that can take the information for the current object and add child created areas. It is likely that there will be managers for page, block, table and list among others. Area Tree: The area tree needs to have all the appropriate block and inline areas and extra information to handle the layout process. Inline areas - character, leader, space, unresolved page, container etc. Block areas - in flow block, relative and absolute position, viewport areas Renderers: The renderers need to be able to handle the area tree. eg. blocks, inlines, fills, clips, viewports, etc. The design includes descriptions of what it does, the layout situations it handles and how it is used. Of course all of these parts will need to co-operate, so co-operation will be needed when doing the design. Across all of these are things like footnotes, floats and links. So far I have started to look at the area tree. So for those people who think they are up to the challenge we can start to get stuck into the lower level design/implementation of the new layout. I think a two week period is enough to get a good view of what we need to do here. So we can aim for 24 Sept. Documents will eventually be placed in docs/design to add to the current information. Any questions/comments are welcome and particularly contributions. Keiron - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Keiron, i would like to help in further development of fop. currently i'm still in the learning stage and because of that i would realy like to read the lastest doc from you in docs/design. unfortunately i don't know much about docbook and the information given in the docs/design/Readme is not sufficient for me to generate the pdfs. The Readme: To convert to pdf: - place the docbook files in a directory name docbook which are the docbook files. and what should be the parent directory of docbook , should i create this directory in the docbook or in the fop package or do i need to create a new directory hirachy for the conversion ? - place docbookx package in a directory name docbookx what exactly is the docbookx package? is it the zip file found in http://www.oasis-open.org/docbook/xml/4.1.2/index.shtml called docbkx412.zip ? the files are avaialable here: http://www.oasis-open.org/docbook/xml/4.1.2/index.shtml what files do i need from this site ? just the .zip ? do i need anything from http://sourceforge.net/projects/docbook ? - run the build script im working on w2k so i need to translate the sh script to .bat. what is jboss and how do i need to set $JBOSS_HOME ? bodo - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

You just need to get the zip file docbkx412.zip and to then unzip it into the docs/design/docbookx/ directory.

Hi Bodo, Maybe it's Windows or maybe it's your Xslt task. The fact that the parser can't find a URI for your document sounds familiar. I mad a change in Xslt a couple of weeks ago which I think might fix this. Assuming you are updating from CVS, please make sure you update the sources and then rebuild the buildtools.jar. using the command build -buildfile buildtools.xml in your xml-fop directory. Hope that helps you. -Karen Lease Bodo Teichmann wrote: Keiron, now i got the pdf but still have the following problems: 1. the relative uri in fop.xml do not work. i get the following error from the SAX parser: Task xslt - SAX ERROR: org.xml.sax.SAXParseException: Relative URI design/intro.xml; kann nicht - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: how to keep together
Hi Suhail, Actually to keep two different FO together, you need to use keep-with-next or keep-with-previous. The keep-together property means to keep an entire FO in the same page or column (if possible). For example, if you put keep-together on an fo:block, FOP should try to keep the whole block in the same column/page. Unfortunately, support for all kinds of keep- properties is quite limited in FOP. They work fairly well on table-rows. Keep-with-next is (I think) at least partially supported on fo:block, so try using that on the block before the table. Good luck, Karen Suhail Rashid wrote: Hi, As keep-together is not supported in FOP as of now how can i ensure that a table and a preceding block appear together on the same page.. Please pass on any ideas u have.. Thanks in advance, Suhail - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Infinately repeating table headers (RE: Concurrency problem? Something else?)
Title: Infinately repeating table headers (RE: Concurrency problem? Something else?) Hello all! About a week ago we experienced a mysterious problem with FOP generating an absurd number of pages and exhausting our memory supply, the whole 1.5 gig! We weren't initally able to reproduce the effect, but, after hacking over the PageSequece class in version 0.17.0 such that it threw an Error in case too many pages were getting generated, we were able to find a test case and trap the input FO which caused the problem. After a bit of analysis it became clear that some combination of table headers and keep conditions were the culprit. I tried making a table with a header too big to fit on a page and FOP remained reasonable: it ouput two blank pages and then ouput the remaining header text on the last page. Adding text to the body of this table simply multiplied the number of pages produced, that is, two blank pages for every page of body text untill the body text was exhausted. Next I tried placing the keep-together.within-page=always property in the block contained within the table header cell; this had no effect. Finally what did it was when I split the header to contain TWO blocks, the first of which had the attribute keep-with-next.within-page=always. This finally reproduced the unbounded condition. I've tested this in version 0.20.1, and it's a problem there too. This is sort-of a documented bug. Bug #1773 describes a similar problem that seems to have since been resolved. Does this merit a new bug report? Is anyone planning on working this, or working on it already? I might tackle this myself, if no one else is planning on doing it--my employers tell me they're willing to let me do this at work :) Thanks all! -Joey -Original Message- From: Joey Carr [mailto:[EMAIL PROTECTED]] Sent: Friday, August 31, 2001 12:15 PM To: '[EMAIL PROTECTED]' Subject: Concurrency problem? Something else? I'm using FOP 0.17 with a hacked over version of Cocoon 1.8.2 that solves the Cocoon embedding problem involving the Writer/OutputStream change in the Driver class (why Cocoon had been stuck on an old version of FOP forever). The hack involves modifying the cocoon method org.apache.cocoon.formatter.FO2PDFFormatter.format() such that the OutputSteam passed to the Driver class is written to a StringWriter en masse at the end of the method. Not pretty, but we're doing small things so the penalty is small. So this morning, on my birthday no less, we discovered that our production system was slowly leaking towards the dreaded OME! And lil ole' me being the one responsible for this stuff! It appears that FOP was generating a giant document and since we were storing the output PDF temporarily as a string, is was sucking up our memory resources. The cocoon format method takes a DOM Document, the output Writer to write the formatted output to, and a Dictionary of parameters, which it callously disregards. The Document is transformed into a String of XML and re-parsed by a SAXParser, so presumably there is no pipeline here, so it couldn't be that the XML data source just keeps making more FO for FOP to render. But continue to render is does! The first snip (at the end of the message) is out of our log of stdout. It appears that FOP is in the middle of rendering a 10 page document when another user request comes in for another report. You can see that the messages from the Driver constructor interrupt the ongoing PDF generation. It appeared to me at first that the concurrent request had introduced some inconsistent state in FOP, exploiting some critical threading oversight... but it's simply not realistic that we had already produced a 10 page report! Our reports are never any longer that 4 pages. The second snip shows my hack over of the cocoon method, org.apache.cocoon.formatter.FO2PDFFormatter.format(), which shows how I'm using the Driver class, and, I think, shows that the XML data source couldn't be the source of the leak since it must be rendered as a String before FOP even looks at it. Is it possible that some freaky arrangement of FOs can cause unbounded recursion in the FOP area formatting algorithm? So, if any of you have any ideas about this, please, PLEASE!! send them along!

embedding pictures
Hi is ist possible to specify the compression rate for images to be embedded in an pdf file?? it is very important to me, because i need the images in a higher quality than fop embedds them until now - without any configuration changes. it would be great, if somebody could help me out of this. thanx daniel = Daniel Pfuhl mailto:[EMAIL PROTECTED] __ Do You Yahoo!?

RE: A C XSL-FO processor
I'm very interested but I haven't done alot of C programming so I may not be of much help in the beginning. I'd especially be interested in Perl bindings for such a project and could definitely help out in that area as I've done some XS stuff in the past. On 10-Sep-2001 Arved Sandstrom wrote: Hi, all I finally buckled, and initiated a SourceForge project to develop a C-language XSL-FO formatter. The link is https://sourceforge.net/projects/xslfo-proc/. Right now there is nothing there...I want to get some people signing up, and register interest. This is for all those developers out there that like the technology (XSL) but aren't turning cartwheels over Java. That includes me. I haven't been able to devote as much time to FOP as I would like, both because of work and also because of a significant developing personal relationship (yeah, yeah :-)), but my intention is definitely not to do less with FOP. I have committed to helping out with the design ideas suggested by Keiron, and have identified a portion that I want to do, and I want to complete marker support. I am also very interested in ensuring that we seek better integration with projects like Cocoon and X-Smiles. The goal behind the SourceForge project is to develop a fast (and I mean fast) low-memory footprint XSL formatter that is optimized for use as a C library. I personally really like SWIG, and I would like to emphasize the development of the APIs so that they are well-suited for SWIGging into Python, Perl, Ruby, and what have you. I prefer to avoid C++. If someone wishes to make arguments for C++ I'll listen to them, but I think OOP is unnecessary for a good solution to the XSL formatting problem. In fact, I am now leaning towards the idea that a procedural design that de-emphasizes the data somewhat, and emphasizes the layout process, is the way to go. Ideas about flattening the area tree figure in my thinking here. I think Java is really bad for promoting the idea that everything should be an object, and I am not sure that this is not complicating our work with FOP. The idea is that this will eventually be folded back into XML Apache (I hope) as a sub-sub-project under FOP. And I also want design ideas developed during the work on 'xslproc' to inform work on FOP. Anyway, there it is, and I hope to see C/C++/scripting language people who are also interested in XSL-FO, support this project. BTW, I have no real stake in being the design lead, although I obviously have ideas, so if someone wants to take charge, feel free. If not, then I will.
