Incomplete PDF content
I am facing a strange problem while generating PDF in Servlet. I have got two PDF reports to generate at present. I can generate one PDF properly, but the other one, whose structure is similar to and simpler than the first one, is coming out incomplete. It gives me the header and footer, and an incomplete body. I tested my xsl by running through the standalone fop.dat (in FOP-0.20.3) against the same XML data. It's generating the complete XML. I am completely lost. Could anybody please help me!

OK, it was a threading issue, I downloaded the source and had a play. It

put
a line in ConfigurationParser.endElement() to only add fonts if there are
none in the list. Was easier for me than mucking around with

That's not a good idea.
If you have only one servlet and set the configuration
only once, do so in the servlet's init() method.
If you have several servlets, create a singleton class
wrapping the instantiation of the configuration,
roughly
final class ConfigSingleton {
private static Options options;
public final void synchronized init() {
if( options==null ) {
options=new Options(userconfig.xml);
}
}
(Beware! Untested!)
And call ConfigSingleton.init() in each of the servlet's
init method.

My other example of Metcalfe's Law in action is Sept 11th. Compare the information flows of those events with the day of the JFK Assassination and the day of the Challenger explosion. Todd Beamer and the other passengers on Flight 97 had cell phone nodes to talk to family members who had televisions which revealed the hijacker's plans. The network gave them the information to make the decision to give their lives to save people in Washington DC. Think about that. They were able to make that decision in this age of hoaxes, spam, worms and viruses.

The landscape does not work -Message d'origine- De : Wayne Elliott [mailto:[EMAIL PROTECTED] Envoyé : lundi 22 avril 2002 14:29 À : [EMAIL PROTECTED] Objet : Fopping and batch printing Howdy Anyone know of the best way to batch FOP generated PDF documents for printing. In our scenario documents are queued for generation, followed by printing, using threads. We print from both a Windows 2000 GUI application and Unix server, by spawning a shell command through Runtime.exec. The commands we use are along the lines of (I'm not at work Win/Dos: c:/Program Files/Adobe/Acrobat 5.0/Reader/AcroRd32.exe + /t + file + + printerName + + driverName + + portName Unix: cat blah.pdf | acroread -toPostScript | lpr The trouble we are having is tracking the print job and knowing when to kill it. In the Dos version we can't get no exit status. In fact we currently count to 10 then kill the process. I think using Acrobat Reader to launch a print job is loony tunes, but am struggling to find a better way. Does anyone know of a better way, either to better control the shell command, or to fire PDF at a printer from Java. Also seeing some corruptiion of the margins in the Unix case. Any Unix gurus know if lpr or acroread need some flags to shrink the margin or set the page size. So many variables... Prob this is all slightly off topic. Not sure. Seems printing is a reasonable thing to do with a PDF so maybe we have all floundered a bit in this area. WPE When not Fopping, can be found floundering with style.

Re: Building a FO document with FOP
Hi Ismaeil, I think Bhawana suggested: DB-JDBC-XML-XSL-FO-FOP-PDF, this includes the additional xml document representation, but puts the XSL:FO instructions outside your java, which would by bypassed by java generated FO documents (your below mentioned construction) It probably boils down to an efficiency decision, but the appealing part of the xsl/xslt layer is the open architecture for applications you might not even think of right now. markus -Ursprüngliche Nachricht- Von: Ismaeil, Sameh Z [EMAIL PROTECTED] An: '[EMAIL PROTECTED]' [EMAIL PROTECTED] Datum: Dienstag, 30.

Re: Building a FO document with FOP
I recommend you don't build XSL:FO through Java code directly. Produce a simple XML format with just the data in it. Use a XSLT stylesheet afterwards to convert the XMl to XSL:FO. It sounds like a lot of work, but you're actually going to save time. For example, if your layout has to change you have to adjust your Java code, recompile, redeploy. If you're working with XSLT you can use some external XML tool, and you just have to switch the stylesheet if something changes in the layout. The whole idea about XSL (XSLT+XSL:FO) is separation of data/layout. You will be a lot more flexible that way! Just imagine you want to generate HTML or SVG instead of XSL:FO. This way, you (only) have to switch stylesheets. Your way means writing the Java classes that produce the XML all over again. This is not exactly what I mean.

Thanks All, I'm well aware of the XSL solution. We had long discussions about the subject of using XSL on XML documents.

Thanks for the quick reply Scott, I don't think I want to use page footers in this case (although I'm willing to if they can solve what I want to do ) - but I understand where you are coming from. The reason is that the xsl I've written produces documents that go over a few pages and I wanted to put a row at the bottom of the last page to show some totals using table-omit-footer-at-break, but keep the size of the table consistent on all pages ( otherwise I could just put an table after the fixed table ) Steve. -Original Message- From: Scott Moore [mailto:[EMAIL PROTECTED] Sent: 30 April 2002 18:12 To: '[EMAIL PROTECTED]' Subject: RE: table-footer at foot of table problem My guess is table-footer is working exactly as intended.

Re: table-footer at foot of table problem
Steve What you could do is set the height of each table row to some length ie 5mm. You then know how many table rows will appear on each page. Count up the number of rows in the table, calculate the number of rows that will appear on the last page. Insert Y empty rows at the end of the table to pad out the table to fill the page.

Are there any companies out there developing products base on FOP? Just curious. I've been looking at using FOP to get print versions of content from a number of web apps but I'm finding it too unstable at the moment to really offer as a solution. Coupled with the rather large resource required to realistically run Cocoon it's a pretty big commitment. The last major update to FOP made changes that rendered earlier .fo files useless without some tweaks. The work involved in ensuring all the .fo files are still working everytime FOP is updated would be a bit of a nightmare. It's a great idea and is going to be a killer solution for designers/developers but it's probably going to take a year or so before it's completely viable. What is FOP now - 0.20.3?

RE: Why is FO(P) a superior model than what most proprietary tool s propose
The short answer is you can't expect a large number of users to ask for reports at the same time and not run into memory problems. Believe me, I've stress tested my report server and hit this wall quickly. 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. At that point, adding more servers can get you better scalability.

Are we trying to fit a square peg into a round hole incorporating FOP into a reporting app as opposed to book publishing? I didn't say you can't use tables spanning multiple pages. I said, if you are running into problems with memory consumption, this could be one cause (out of many possible others). The standard procedure when you are getting OutOfMemoryExceptions is: 1. Look for a bigger machine, and increase JVM memory settings (they should not exceed physical memory). This will only go so far. 2. If you are running a servlet, serialize requests for PDF rendering. 3. Get rid of forward references. This is often a really big win. 4. If you have some amount of large graphics which is scaled down by FOP anyway, scale them down before you feed them to FOP. This helps especially if you have inncently looking highly compressed but high-resolution JPGs (something in the 1000x1000 pixel range, one such critter can eat up to 5MByte). 5. If everything above is already stretched to the limit, simplify your layoput and the intermediate FO structure. However, unless your whole document is a single table, this is often small change. Nevertheless, some small modifications in the style sheet can make a difference between working and not working. J.Pietschmann
