Re: fop in tomcat-4.1.18 and struts-1.1-b2
The conversion from .fo to .pdf seems to work using the tomcat xml libs. Don't think tomcat comes with xalan, so hopefully I can just throw fop's xalan.jar in my WEB-INF/lib, will find out soon. Looks like struts-1.1-b2 depends on some xml parsing functionality that is specific to the version of xerces that comes with with tomcat, but thats just a guess on my part.

Just try it. Make sure the Tomcat's XML parser is visible to the webapps.

Perhaps, somebody on the FOP-USER list has > experienced this problem and can give us a solution or pointer. The problem is that FOP does not handle spaces conditionally, as a poster in the snipped part already mentioned. It's not specific to lists or tables. The only solution is to avoid generating space-before/after properties at places where they are not wanted. Of course this works only for table cells, at page sequence boundaries and around forced breaks. There is *no* solution for page breaks. And of course this complicates style sheets. This will not be fixed in the maintenance branch. It's not yet adressed in the redesign either.

RE: FOP performance - frustrating.. help!!
From: Bob Leif To: Lee Insoo A good deal of your problems comes from the selection of Java as the programming language. Java is a tremendous marketing success. Unfortunately, Java was obsolete the day it was created. Although Java is owned by SUN, it has been the second finest gift to Microsoft. It has their competitors using a flawed tool. The finest gift was when IBM told its customers that OS/2 would run best on Microchannel hardware. The best language for web tools is Ada, which is ISO/IEC standard 8652:1995(E). It is what Java claimed to be, portable. Ada includes generics (templates) which work; enumerated types; and, whenever possible, dispatches at compile time. Ada is like XML in that it has range checking and begin and end structures. There is an excellent GNU Ada compiler (GNAT) available at ftp://ftp.cs.nyu.edu/pub/gnat/ On a 1.4 gigaHz Pentium, the time for a GNAT compile and link is minimal. The error-messages are excellent. http://www.adaic.org/ is a source of useful information on Ada. -Original Message- From: Lee, Insoo [mailto:[EMAIL PROTECTED] Sent: Friday, December 27, 2002 12:30 PM To: '[EMAIL PROTECTED]' Subject: FOP performance - frustrating.. help!! Hello, I'm getting a little frustrated with FOP performance. We are generating an XML on the fly that contains a few tables with about 1,000 rows in total. We passdown this XML along with XSL to the transformer to generate PDF from our servlet. (transformer.transform( inXML, new SAXResult( driver.getContentHandler())); ) It works well, but it works slow. It takes about 5 minutes for 1,000 rows and this is only for transformer translation (excluing any data query time or jdom XML building time) I read through past emails/FAQs and I think I tried them all and it still does not improve the performance... Please help!! Here is what I have done. 1) run with more memory - yes I tried with 512MB (I don't get OutOfMemory error) 2) run in separate VM - only helps other requests coming to the site 3) try with the latest FOP - I did - mine is fop-0.20.4 4) try with the latest xalan.jar and xerces.jar - tried them, but no improvement 5) cache XSL style sheet - didn't really help... 6) use multiple page-sequence - got it to work and I don't get OutOfMemeory exception, but still performance didn't get better. (even if I break them into multiple page-sequences, I will still have to read through one row at a time, right? - that's why performance is not really improving..) 7) no forward-reference - I don't have any page numbers 8) try with new JDK - trying with JDK 1.3 9) seralize servlet request - haven't done this, but I doubt this will have any performance impact (I'm testing with one request for now) 10) no images - I don't have any... 11) Don't make the XML tree too deep - mine is very flat with 2 levels deep. I have 1,000 rows and each row looks something like following in XML 539 Some Fund 0.376 NA NA NA NA 1.4 1.58000 1. 09 Dec 2002 USD I Here is the question: Is this normal to take this long - 5 minutes - to produce a few tables with combined total 1,000 rows (about 30 pages)? Any other better way? Thank you for your suggestions.
