Hi Anyone have an idea about how to increase memory for FOP programaticaly.I get Out of Memory error when I try to user the transform() Method of the Transformer Class Thanks Rohit - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Again out of Memory Error -2
Ok I'll try to answer both part 1 and 2 here : as for the JVM memory parameter with servlet engines : Your servlet engine is executed in a JVM that must allow you to set memory parameters. I don't know about every ServletEngine or ApplicationServers but you can do this with Tomcat or Websphere so I guess it exists everywhere. As for multiple page sequences, it is simply a fact that the current FOP implementation seems to keep a whole page sequence in memory before it writes it down. So the biggest bage sequence you have, the more heap size you need. Therefore it can be helpfull to create separate page sequence anytime you can. In your case, it is the worst situation : one long table. You have to start and stop the table each time you want to change page-sequence. Some guy on the list had the same situation to deal with. He manage to have an average number of x row per pages. Then he twisted his XSLT stylesheet to take x rowData (detail element in your case) to build one page sequence containing one table with the x rows and so on. He has ended with a 97 page-sequence document. This may be a little extreme but it works. The archive pointer I gave you does this trick. In many case, you have to deal with many tables wich are not always 100 pages long then you can place page-sequences every time you know you can have a page break. I hope this helps. Cyril
Re: Again out of Memory Error -2
Hi Cyril, Thanks a lot for replying. I'm using Tomcat 3.2,so I think there shd be someway to imporve JVM heap size. Now I understood the multiple page sequence advantage.I tried to change my to have XSLT to print 20 rows at a time,still coding/re-coding my XSLT to get a good result and not yet completed. Since this is a one-off job,I converted my large XML data to HTML,then I converted HTML to PDF using Adobe distiller.So the task is done,but I'm half baked now with my XSLT code. Thanks a lot for replying me at right time.

Again out of Memory Error
Hi, Recently many people were discussing abt avoiding out of memory error,I read previous threads but couldn't able to find solution for me. Is this error related to Number of pages or input xml size.Because i have a xml with 1588 group of element,which i have to render into PDF in table format.I can minimize the page size by reducing the font size.At present its generating upto 51 pages then it throwing out of memory error. Some constraints.. 1.I have to embedd a new font called Arial UniCode MS(the ttf file size is 23mb) for Unicodes. 2.in xsl:for loop,i have used xsl:choose with 15 xsl:when's. So is the error is related to XML file size or number of pdfpages or xsl coding style. ?? I can send xslxml personally if needed to avoid unnecessary bulking. Please suggests.

Re: Again out of Memory Error
I suppose you are using FOP 0.20.3... first, what amount of memory do you give to FOP ? meaning do you use -Xms and -Xmx jvm parameters to give Java JVM the memory needed ? Second please state how many tables there are in your document, and how many pages long the longest table is. Do you use as many page sequences as you can ? Long tables and long page sequences are known to increase the memory requierments of FOP. error has nothing to do with xml. Xsl could be used to create additionnal page sequences. List Archive shows you how. I hope that helps.

Re: Out of Memory Error !!
The problem is probably your page-number-citation that looks up the last page. This is well known to have impact on memory usage, because FOP can render the first page only after the last page has been setup. It has to wait until it knows how many pages your page-sequence has. Take out the page-number-citation and look if the problems go away. I'm pretty sure they will. That means you might have to live with page x instead of page x of y for now.

Out of Memory Error !!
hi there !! i am getting out of memory error when i try to process a very large document containing a single fo:page-sequence tag a single fo:table tag. i have gone thru the mailing list looking for some solution to this problem but though the problems are similar i am not able to figure out the soluition in my case... as i cannot have more than one page-sequence to display my actual data... i want to know what can be done to get rid of this problem if some how i am able to break this page-sequence then i will be able to get rid of this problem... kindly help me out with this problem as i am a novice in with this FOP stuff.. if any further info is required then send a mail a [EMAIL PROTECTED] thanx lotza cheers !!

Re: Out of Memory Error !!
Hi Abhijit, Looks like it might be in a recursive mode or something. I am not totally aware of this kind or problem ,but how big is your document ? Are you using the combination of xml and xsl filer or just the fo file to print out in PDF? naveen Abhijat Upadhyay abhijat.upadhyayTo: '[EMAIL PROTECTED]' [EMAIL PROTECTED] @patni.com cc: Subject: Out of Memory Error !! 05/08/02 02:44 PM Please respond to fop-user hi there !! i am getting out of memory error when i try to process a very large document containing a single fo:page-sequence tag a single fo:table tag. i have gone thru the mailing list looking for some solution to this problem but though the problems are similar i am not able to figure out the soluition in my case... as i cannot have more than one page-sequence to display my actual data... i want to know what can be done to get rid of this problem if some how i am able to break this page-sequence then i will be able to get rid of this problem... kindly help me out with this problem as i am a novice in with this FOP stuff.. if any further info is required then send a mail a [EMAIL PROTECTED] thanx lotza cheers !!
