RE: Java script with xsl in FOP ?
Here's how we insert a dynamicly generated script it in the xslt that passes through to the HTML: script language=JavaScriptloadTopFrame(quot;xsl:value-of select=$print-csr/quot;,quot;xsl:value-of select=$print-quick-trend/quot;,quot;xsl:value-of select=$print-quick-visit-history/quot;);var protocolId = 'xsl:value-of select=@PROTOCOL_ID /';/script As you can see it could get a little ugly with large functions, but I think it should still be possible to carry anything through to the HTML. Good luck. -Matt -Original Message- From: Clay Leeds [mailto:[EMAIL PROTECTED] Sent: Friday, September 12, 2003 10:05 AM To: [EMAIL PROTECTED] Subject: Re: Java script with xsl in FOP ?

I've done some fairly complicated mathematical calculations using a combination of XSLT and XPath functions. In either case, this is somewhat off-topic for the FOP-user list. You should be able to find more information by searching for numeric functions in XSL or XPath.

RE: Java script with xsl in FOP ?
Yes, I think it is feasible. Here's some XSLT code we have that tests string length and forks based on the result: xsl:choose xsl:when test=string-length(@PRIMARY_ID) lt; 11 xsl:value-of select=@PRIMARY_ID / /xsl:when xsl:otherwise xsl:value-of select=substring(@PRIMARY_ID, 1, 10) /#xA0; xsl:value-of select=substring(@PRIMARY_ID, 11) / /xsl:otherwise /xsl:choose I think everything else you require would just involve a few more nested xsl:choose statements for the alignment types. -Original Message- From: Abhijit Junnare [mailto:[EMAIL PROTECTED] Sent: Friday, September 12, 2003 10:47 AM To: [EMAIL PROTECTED] Subject: RE: Java script with xsl in FOP ?

RE: Convert existing PDF to XSL-FO tool
We started using FOP based on the same requirements and have been thrilled with the results. If you can get from XSL-FO to PDF, I'm not sure why you might need a path *back*. If you are looking to create the PDF through something like Acrobat Exchange, then spit out the xsl:fo, you may be in trouble. But if you're willing to sit down and learn xsl:fo, IMO FOP makes a nice, powerful, free solution. Although I have heard of XSL:FO WSYWIG editors in the works.

I using Apache Velocity which has an inbuilt template language (VTL) to fetch data from Java Beans on to any text file. The dynamic data are merged with XSL-FO template using Velocity and the resulting XSL-FO file is then given to FOP for generating PDF. Not sure what to make of this: first you don't use XSL-FO from XSLT, but you *are* using an XSL-FO template? (Would the latter be a FO in which some sort of a classic search-and-replace is performed? In that case, I do think XML+XSL-FO is a more than valid alternative. Meaning: perform the merging with Velocity in a 'template XML' that could afterwards be styled - e.g. via Xalan - to deliver the FO) I agree that reverse compiler are not precise, but I am a novice in XSL-FO template creation. It would be of great help if any tool can provide a good start on which I can build on. It would be good enough if I could copy-paste the PDF file content onto some XSL-FO editor and it generates the XSL-FO for me. Is anybody aware of such a XSL-FO editor?. I heard of XMLSpy, when I searched the Google, but not sure which is best for my requirement(ie., with existing PDF and free if possible). First of all, I know of no such tool ( In fact there are AFAIK no tools that take a pdf as basis and deliver some other output-format, I guess the process would just be too complicated ). Also, difficulties would probably arise when a tool like this would deliver XSL-FO containing tags or constructs not yet supported by FOP ... Second, I think XMLSpy would not help you out here ( AFAIK they do offer an alternative to FOP, so I cannot help but NOT recommend you this ... ;) ) And third, I really think this would not be a good way for an XSL-FO-novice to start learning XSL-FO template creation. Start from scratch as this will definitely learn you more about what the fo-tags do... (first-hand experience and all that) If you insist, however, on having someone/something else perform the pdf to fo translation, send us a pdf and I would be more than willing to help you on your way to make a fo for that kind of layout.

Reports are the root of all evil, oh well. Your small attachment expands to an impressive 4MB file, which contains a single table with roughly 30'000 cells. It ultimately run out of memory around page 4 on my JDK 1.3.1 -Xmx64M on WinNT.

This means that memory is already pretty tight before the layout process even starts. I also the repeated font-size=8pt and text-align=start causes some bloat, and deleting them reduced the overall number of created objects by 10%. However, the effect on run time was neglible. Increasing the mx setting resulted in memory thrashing :-/. A closer look at the memory profiler statistics showed that all the layout data associated with table cells still hung around in memory at the time memory runs out. Digging further this turned out to be caused by table objects clinging to their layout data indefinitely. That's bad. I put in a small hack, using the area's back pointer to release the data for Table, AbstractTableBody, TableRow and TableCell after rendering. This allowed me to render the file, albeit slowly due to frequent GC. Unfortunately I'm reluctant to commit the change because it is likely to break some things, in particular putting IDs on a table will cause trouble in certain situations. This could probably be fixed too, but the more the scope of the code change is broadened the more testing would be necessary before the next release. Conclusion: don't use tables, as they lock up a lot of memory until the page sequence ends. If you have to use tables, use short page sequences. Some additional notes: the most objects created in total were of class String (3'738'853), which is no surprise, followed by java.lang.Object (571'663), ArrayList (389'319), HashMap$Entry(278'527) and HashMap (122'702), which *is* a bit of a surprise. I guess the j.l.Object counts the various arrays. Hashmap entries, lists and the objects tended to be fairly persistent, with more than 100'000 lists and objects as well as 135'000 hashmap entries still being referenced at the end of the run. The hashmaps itself are less likely to be kept, only 7'500 out of a total of 122'000 have been left. This means the persistently referenced hashmaps keep an average of 13 entries, while the overall average is 4.7 entries per hash map. A few maps with lots of entries, like the ones holding the mapping from element names to element factories may account for much of the difference. OTOH the low overall average indicates that many of the hashmaps stay empty, there ought to be quite some potential for optimization. I suspect many of the lists stay empty too.

RE: Big/Huge XMLs
[I'll give J. a breather on this one] Assuming you've made certain that the bottleneck is in FOP and not your XSLT transformation, the only thing you can really do to help with very large reports is to break the PDFs into multiple page-sequences. IE start a new page-sequence every X nodes. If you have natural page break that you can use, no one will ever notice in the final output. Otherwise you may have awkward page breaks in your document. I have attached an XSLT stylesheet that we use to essentially break theXSL:FO into "chunks". Every 10 Investigator (=doctor) nodes we start a new page-sequence. Since this report has a page breakfor each new investigator anyway, the end result is no different. We increased our max PDF size on this report from 30 pages to 200 using this method, and seriously sped up rendering time for large reports. FYI - weare runningWeblogic on HP-UX with -hotspot, max-heap-size=512MB. For some reason, the Wintel JVM seems to perform a lot better than HP-UX on FOP, and in general. Note: as originally pointed out on this board, there is actually a slicker, and probably more efficient, way to do the node processing using a recurring template. ButI just found out how to do that and our bottleneck isn't in the XSLT so I haven't had any motiviation to go back and fix it. Here's the example: http://www.dpawson.co.uk/xsl/sect2/N4486.html#d4085e94I like Steve Tinney's solution to the grouping problem.

RE: Big/Huge XMLs
30 pages is not our absolute max, but we have set a requirement that we have to be able to handle at least two concurrent reports, so we need some cushion. I have attached some FO for a report that runs around 50 pages, using only one page-sequence. I would really appreciate it if you coule run it through your FOP processor and tell me what kind of performance you see. It runs on our system, but two of these at once will come very close to an out of memory error. I have a feeling the large performance discrepancy may be because our report is one large table. Please let me know what you find. Below is the log output for a slightly larger (66 page) report also using only one page-sequence. I had to do some de-indefication to create the report I attached. But this log output is from the exact same report, just slightly different data. As you can see at -mx256m, we come close to an out of memory error on just this report. Once we implemented the page-sequence chunking though, full garbage collection knocks memory-in-use down to the range of 25-75MB depending on the report. This is a big improvement over the 215MB that you still see in use below even after a full GC. This was run on my Windows dev box (PIII 850Mhz 512MB ram) set to -mx256m. Memory performance and speed are always much worse on our production boxes( HP-UX, 2x550 RISC, 2GB ram) set to -mx512M -- especially on 2 or more concurrent reports. We're trying to talk our infrastructure police into letting us set up a Win2k server with Weblogic as a dedicated PDF report generator. No luck yet.

Woops, that first fo:table-cell... tag below should have been removed. Actually if you use this: xsl:for-each select=../customerPF[$row-num lt; position() and $row-num+4 gt; position()] instead of the xsl:for-each followed by 2 xsl:if-s below, our code might be somewhat efficient after all. I just tested and it seems ok on first pass. Apparently we were still learning our XSLT back then.

RE: Column / character width question
I can't read the text because I'm missing a font (Might want to look into that for your end users. I have the latest Acrobat 5.0 Exchange.) So if I understand, the problem is creating flow in the main/body two-column section around the top section two-column thing on page 2, which is different from the one on page 1. Is this correct? I think there may be something you could do with markers and table headers to set each block as a table header, then switch the content. This is what I need to figure out (someday) for our tables where we want to add 'CONTINUED' on every page after the first that the table spans. Although I don't know if you can wrap this whole 2-column flow into a table. Maybe you could do the same with region-before. Have you looked at the attached example from FOP? Could you use something similar to block 4, but put your images and tables in it? -matt -Original Message- From: Ben Galbraith [mailto:[EMAIL PROTECTED] Sent: Thursday, May 08, 2003 3:56 PM To: [EMAIL PROTECTED] Subject: Re: Column / character width question Savino, Matt C wrote: So I'm guessing the text below the pics in the upper split section is a continuous paragraph?

Instead of trying to determine when the first cell is filled up to wrap to the second, I could simply balance the two cells -- calculate the total number of items -- oh, but wait, I still have the same problem because to properly balance them I would need to know how many lines each item occupies.

RE: Column / character width question
Thanks Clay, looks promising. I may have to finally upgrade from FOP .20.2 to test it. From what I understand markers weren't well-implemented in this version. Basically what I need is for the word 'Continued' to appear at the top a block (table) of results every time there is a page break. The table is nested within several others. Do you think your system will work within tables? My first thought is no. The surronding tables have several sections of varying height, so I can't implement them as region-before. If only they had a table-omit-header-before-break to go along with table-omit-header-after-break. -matt (OT) I've got 'continued' working in my FO, where it indicates Continued on next page... on all pages except the last.

RE: Column / character width question
I'm missing a font so I can't see the text. Does the upper two-column section need to flow like the lower one? Can it be the same height every time? Is there a new upper two-column section on every page? That's some complicated layout you have there, almost looks more like a catalog you would do in Quark. -Matt Scott Moore wrote: Is the text in Key Facts dynamic? Why can't you use a 2 column table in that region? If the text is always the same, you should be able to format it in such a way so that it looks like it flows from one column to the other.

RE: Seeking advice on HSSF
Thanks Jeremias. I think the main reason we are parsing the fodoc into a DOM is so we can serialize the FO out to a file for debugging (it's either that or do the transformation twice). I'm actually in the process of altering the HSSF stuff now so I can debug the GMR output. On your adive I will change both of them back to a stream source for production. Although I seem to remember experimenting extensively when we first started with SAX vs. DOM input sources using the FOP XSLTInputHandler, SAXHandler, etc. As I recall, we didn't see much difference in performance. But I will try it again for this round and let you know how it goes. Actually here is the old commented out code from these tests: File xmlFile = new File(xmlFilename); File xsltFile = new File(xsltFilename); org.apache.fop.apps.InputHandler inputHandler2 = new org.apache.fop.apps.XSLTInputHandler(xmlFile, xsltFile); org.xml.sax.XMLReader parser2 = inputHandler2.getParser(); driver.render(parser2, inputHandler2.getInputSource()); Is there a more efficient method I should try? thx, Matt org.w3c.dom.Document xmlDoc = dBuilder.parse(xmlFile); javax.xml.transform.dom.DOMSource xmlDomSource = new javax.xml.transform.dom.DOMSource(xmlDoc); org.w3c.dom.Document xslDoc = dBuilder.parse(xsltFile); javax.xml.transform.dom.DOMSource xslDomSource = new javax.xml.transform.dom.DOMSource(xslDoc); Why do you parse the whole thing into a DOM? That's very inefficient when you subsequently give it to JAXP anyway. A StreamSource would be a lot better! Have a look at the Example*.java in the latest FOP distribution under examples/embedding. javax.xml.transform.TransformerFactory tFactory = javax.xml.transform.TransformerFactory.newInstance(); javax.xml.transform.Templates templates = tFactory.newTemplates(xslDomSource); javax.xml.transform.Transformer transformer = templates.newTransformer(); ByteArrayOutputStream out = new ByteArrayOutputStream(); org.w3c.dom.Document foDoc = (org.w3c.dom.Document)domResult.getNode(); Again, don't do that. Use SAX as with the HSSF serializer: Result result = new SAXResult(driver.getContentHandler()); transformer.transform(xml, result); See how similar the code is to the one for HSSF? org.apache.fop.apps.Driver driver = new org.apache.fop.apps.Driver(); driver.setErrorDump(true); driver.setRenderer(driver.RENDER_PDF); driver.setupDefaultMappings() ; driver.setOutputStream(out); driver.render(foDoc); response.setContentType(application/pdf); - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: FOP in production app
FYI - we use FOP in an online production app to deliver on-demand print verions of our managment reports and lab reports. Our clients (drug companies) use the app to log on and see how their clinical trials are going. Luckily we haven't had much demand for large (50+ pages) PDFs or many medium-sized reports being run concurrently. If this demand ever does appear, we know we would have a major performance issue on our hands. We would have to create a task-scheduler to run larger reports during off-hours. We did test RenderX's product, XEP, and generally found performance the same or worse than FOP. Support was really spotty as well. One report took about 10 times longer on XEP than FOP. I emailed their sales address and made it clear that only chance these guys had for a sale was to help me figure out what was causing this gap. After a week or so wait, the president of the company called and told me to call tech support, but not to tell them he told me to call because they don't like that. Tech support finally said they couldn't help me. At $5000/CPU (not even purchased yet!) I was expecting a little more. It was kind of surreal. IMO anyone who thinks you are guranteed to get any kind of support after the contract is signed is living in the past. There are good companies out there (I would put BEA at the top of the list), but don't assume you're going to get top-notch support just because you spend some $$$ or sign a maintenance contract. I hope I don't sound too much like a commercial for FOP, but given this experience I'll take an open-source project with a dedicated user and dev community over a sketchy dotcom-ish company any day.

RE: Pass xsl:param value to FOP through command line
Not sure exactly if your .BAT file is calling a Java app or something else,
but here is how we set an external xsl:param within our report generator
servlet:
transformer.setParameter(pdfImagePath,
getServletConfig().getServletContext().getAttribute(pdfImagePath));
Then the xslt stylesheet access it like:
xsl:param name=pdfImagePath /
We use this to get the environment-dependent path to our image directory:
fo:external-graphic
src={concat($pdfImagePath,'ClinTrialLogoGreenBig.gif')} /
But you could use the value of this param to make decisions within your
stylesheet.
Hope this helps.

RE: Pass xsl:param value to FOP through command line
Do you use XSLT to generate your FO file from XML data, or are you building
it some other way? I know you can pass properties to FOP through the command
line, but as far as something like don't print the second page, I imagine
that would have to be in your FO.

Matt,
Thanks. Actually, my .BAT file is calling _FOP_ through the
command line.
As for servlets, I don't think we are using them at all.
Because all the
examples I've seen discuss how to pass param values to
servlets instead of
how to pass them to FOP, I was stuck.
However, Thorsten gave me a great workaround for the problem
I was trying
to resolve by passing a param to FOP. I still would like to
know if there's
a way to pass param variable values through the command
line, though.

RE: blank screen in browser
Check to see if there's anything different about their internet settings or IE build than the other 99%. Look behind the scenes to see if your servlet is being called twice. It sounds like it could be some quirky caching behvior on just those browsers. Even the newest versions of IE call the PDF generator servlet two or three times, it's just that they usually call their own cache on the second or third hit, so you don't see anything. If you set the response-header to no-cache you'll see what I'm talking about. Are you using SSL? If so, check that [Internet Options:Advanced:Security:Do Not Save Encrypted Pages to Disk] is not checked. We had some problems with corporate builds that have this setting checked by default. IE can't handle dynamic PDFs over SSL w/o caching them apparently.

RE: blank screen in browser
Not necessarily. If only a few people's browsers are actually sending a second request through to the servlet you might only see an error then.

RE: Possibility of converting from XML to PDF without the interme dia te stage of FO format
If performance is everything, you might look into some of the proprietary
PDF engines like faceless.org. But either way I believe you're still going
to have to convert your raw xml into something marked up for display, then
feed it to the PDF generator.
Does anyone have any experieince with faceless compared to FOP
performance-wise?

RE: Performance Guidance
J: No offense meant, but most people start with the most inefficient ways to generate XML, usually doing a lookup in a remote database (which is slow, but hard to avoid), building an XML string or a DOM tree (which is slow, memory consuming and avoidable) and then feed it to the XSLT processor. I meant to ask--what alternatives do you suggest to that avoidable second step as far as getting to the XSLT processor? thx a lot Matt Savino
RE: Performance Guidance
That's really good to know. Thanks Matt Savino Doesn't XSLT ultimately need it's source XML in a DOM object to run? It depends. One point is that DOM is an interface, and there exist heavyweight and leightweight implementations. Some XSLT processors can work directly from an arbitrary DOM tree as long as read interface is supported. Many XSLT processors prefer to build their own internal representation of the XML tree for efficiency rather than using a DOM implementation from a library, quite a few do this even if they are fed a DOM tree. The internal XML tree representation may or may not resemble a DOM implementation, and may or may not use or provide a DOM conformant interface. Some processors, specifically Xalan, are capable of streaming processing. They analyze the templates and start processing immediately once a sufficiently large subtree is read. Subtrees which has been processed are discarded, so there is never a complete DOM in memory. This work especially well if you are creating a (HTML-) table from a DB query result. J.Pietschmann
RE: Performance Guidance
I mean every other thread has to wait. I have the FOP processor wrapped in a stateless session bean and I limit the number of instances of that bean to one. This is because of the serious performance drop-off we see when FOP is run more than once concurrently. I'm still working out some of the details.

Any guidance on how to embed FOP and get better response time is appreciated. The design of the embedding hardly matters for performance. The complexity of the layout usually matters. How much time does FOP need to render your FO from the command line? Does the time include the XSL transformation or is it FO rendering only? Use the -d switch to get timings. Do you use JDK1.3? Is HotSpot enabled? FOP is much slower on JDK 1.2 and earlier. Try to isolate the steps. Apply a profiler. You might find bottlenecks where you'd expect them last. In your case, I strongly suspect the bottleneck is data retrieval, not FO rendering, 7 seconds for a page sounds too much. You ought to get 1-2 pages per second on moderatly dated machines.

RE: Memory usage on lage documents
If you know that none of your table cells are going to wrap you could count rows at the XSLT level and put in a new page sequence every x pages. This defeats a lot of the elegance of FOP, but could work. My problem is I have lots of random cell-wrapping, and I'm not about to start trying to calculate in my XSLT when FOP will wrap a cell.

Mai 2002 16:49 An: [EMAIL PROTECTED] Betreff: Re: Memory usage on lage documents Mirko, there are many post on this list that point out the weaknesses of the FOP engine. The main enemies are : long page sequence and forward references. If you use long tables, then you most certainly have long page sequences. If you have logical page break in your tables, please, change your XSLT code to generate page-sequence break in your tables. The shortest page sequence the least memory used. As for the lot of time to complete the work, it appear that forward reference may be responsible for this. I hav had the same proble for 400 to 1000 pages documents that have the famous total number of pages at the bottom of every pages. I have successfully set up an unclean workaround : I generate my total number of pages after PDF generation is complete using iText software. I even generate my toc at the end of the fo file and then I move it at the top of the document and then write the number of pages at the right place on every pages. This is pretty simple if you look at iText sample code (itext.sourceforge.net). The last thing : C++ or C or ASM formatter won't help much because it is the global design that makes FOP slow and memory consumer. The redesign is on it's way. The workarounds I have mentionned are just gizmo to allow one to wait for the next generation of FOP. Hope that helps, Cyril At 16:29 06/05/2002 +0200, you wrote: Hi there folks!

RE: OutOfMemory - What worked for me.
This is great if you have logical page breaks. Only one of our reports has any logical page breaks however. So I can insert new page-sequences every 1000 rows or so. But unless I start counting rows and trying to guess at when a cell wraps, I have no way of preventing page breaks that leave awkward-looking partially filled pages.

Hi guys, I had been having the memory issue over the last number of days. My fix that has worked and probably been posted before was to split up the pages of my file using a correct implementation of page sequences. Previously I had been pumping all data into one page sequence and breaking it using page breaks but FOP simply kept loading this into memory until eventually it ran out. Now I just load a page sequence at a time and this allows the garbage collector to run once all available memory has been allocated and thus free up memory used by earlier pages. As long as there is enough memory for a single page you shouldn't need much more as the collector can free this once the page has been rendered.

However, if you write your server to only run X number of reports at once and queue any other requests until other reports are finished, you can avoid those problems and achieve a robust and stable FOP server.

For the report I was running, FOP was about 10 times faster than RenderX. But from most accounts performance between the two should similar.

The memory requirements depend on the complexity of the layout (tables spanning multiple pages are bad), how big included graphics are (they are all held in memory), and, often the worst of all, whether you are using forward references, like the popular page x of y (which forces all pages and dependent data to be held in memory until rendering is finished).

OT: Mime Types
Can anyone point me to a good references on getting various response content types/file extension mappings to work with IE and Netscape? I'm having a devil of a time getting CSV and XML to save correctly AND create the correct user prompts. We'd like the open/save dialog to come up for everything, but we'd also like to have the correct extension show up when the user goes to save the file. Customizing the filename for each instance is not important. IE - QueryOutput.pdf, QueryOutput.html, QueryOutput.csv, QueryOutput.xml is fine. For CSV, if I set the content type as application/excel and the user saves the CSV file, it gets saved as a binary file. Which is fine for everything except Notepad and Access 97, which apparently can't convert to ascii correctly and don't see the line breaks. If I change the content type to text/csv, IE works fine, but Netscape saves the file with some extra carriage returns and weird characters. I could set separate content types based on browser, but the users with Netscape who want to import their CSV into Access 97 are still out of luck. For XML, IE seems to always want to open any mapping with a .xml extension no matter what you tell it the content is. We'd rather give the user the option to save first. Also, IE 4.x tries to open every XML file it sees, but can't -- even perfectly good XML files sitting on my hard drive. XMLSpy is set up as my default app for .xml, but if you're already in the browser I guess IE just ignores that. Finally for HTML in Netscape, for some reason after I open the XSLT stylesheet in a new window, when I go back to the opening window, I have weird box characters all over the place -- on a page that doesn't get redrawn at all. I've seen the same behavior on slightly different versions of communicator 4.x on NT4 and Win2k. Very strange. I attached a screenshot. Anyone else seen similar behavior with Netscape and stylesheets? Thanks a lot, I know none of these are related to FOP. But I also know from hanging around here that a lot of you are fighting with some of the same issues in your multi-output systems. I've been searching the web and found some good info.

Simplified, my page needs to look like this (The '_'s and '|' represent the actual printed border): top of page __ |static header | |__| __ |table header | - |__| | | table | | | content| | | | I'd like this height to be constant | (can span| | | multiple| | | pages) | | |__| - bottom of page The problem is I can't figure out how to get the border around the table to always extend to the bottom of the page. Right now if the table ends after three rows on the third page, so does the border. I keep thinking there must be some simple way to do this that I'm missing. This border can/should be in the exact same position for every page in my report, so maybe I can do something with region-before and region-after? I think the tricky part is that the table can span multiple pages. Right now I wrap the entire content table in a single-cell table, and put the border in the column definition of that outer table. I used column because I also have some stuff in the header of the outer table that may or may not be repeated after the first page--depending on business rules. I'm pretty sure if I put the border in cell or block has the same effect. I've attached the FO and PDF if anyone wants to look at it.

Subject: setting a property with value of a variable
Hi
I want a set of tables with alternating background colours.
To do this I
intend to set the background of the table with the value of a
variable which
will contain white or grey. How do I do that?. Presently my .XSL
contains this -
xsl:template match=record
xsl:variable name=bakColor select=yellow/
fo:table background-color='xsl:value-of select=bakColor/\'
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-column column-width=20mm/
fo:table-body
xsl:apply-templates/
/fo:table-body
/fo:table
/xsl:template
But I am getting this error when I try to apply it to my XML file -

RE: Keeping it together
Supposedly in .20.3, fo:table-row keep-with-next=always works. In previous versions it went into an endless loop if the rows went beyond the end of the page. Has anyone used .20.3? I didn't like the the logging errors and two new jar files I was supposed to use. And I missed my benchmarking output (the time not the memory). I posted on fop-dev to ask if there was any way around these issues but no one replied. -Matt -Original Message- From: Jozef Chocholacek [mailto:[EMAIL PROTECTED] Sent: Monday, February 18, 2002 11:12 PM To: [EMAIL PROTECTED] Subject: Re: Keeping it together Lars Karschen wrote: ... I tried to connect them via keep-with-next.within-page=always, but there's no change on the output, maybe i overlooked something, since i'm not sure if i understand the definition on the W3C-Page ;) You understand it good, but FOP has no or just a symbolic implementation of this property(-ies). Keeps doesn't work in FOP :( It is the most important feature to be implemented, from my point of view, anything else works good enough for my purposes. Regards, J.Ch. -- Ing.
