Fop servlet crash after some days
Hello, 1) The problem : The servlet crash after few days (some time 3, some time 20). In the tomcat logs, we get the following error : StandardWrapperValve[Fop]: Servlet.service() pour la servlet Fop a généré une exception java.lang.OutOfMemoryError We have to restart Tomcat. On an older server, with a smaller processor, the same java and same tomcat, the servlet never crash (with less activity too). 2)The context : I am succesfully using fop servlet to generate on fly pdf file. The file are between 100Kb to 1Mb, with 1 to 3 pages. Most of the zize comme from the inclued images (3 to 9 photos in print quality size). The servlet produce about 15 PDF file per hours. When tomcat start, and after some run of fop servlet, the java process are arround 30Mb and increase all the time. 3) What we try : We tought the problem come from the image cache. We run a script who ask for a static fo file modified with PHP to change all the image urls by adding a timestamp to avoid fop image cache. The shell script loop 1000 time and is running 3 or more time. If the script wait 2s beetwen each fop generation, the memory usage go to 158Mb for each java process and stay stable. fop does not crash. If the script don't wait, the memory consumption increase very fast to 273Mb for each java process, many process crash and tomcat create new process. The servlet become unstable and at the end do not respond anymore. The second test where the script don't wait has no real word equivalent. The first script waiting 2s look like the reality. 3) Detailled question : I do not reset the image cache because of Internet explorer who use to call 2 times an url to download the pdf. By caching the image, the second generation is very short. I thought fop is caching all photos and growing in memory size, but our test can not reproduce the crash in the same situation. We see the memory consumption increasing and the garbage collector never run. Do I have to manualy reset the fop image cache or does fop reset itself ? If i create a dedicated method in my servlet to reset the cache should I take care about anything special ? My cheef don't think it's the image cache the problem, do you have any suggestion to investigate ? Thank by advance for your advices.

RE: Base font and russian
Chris is right. The base14 fonts (Helvetica, Times and Courier, not Symbol and ZapfDingbats) are defined in ISO-Latin1 format (if I remember correctly). You won't get around using an embedded Unicode-TrueType font. Thank you for your answer. I use the Thryomanes 1.2 font (http://www.io.com/~hmiller/lang/) and it works fine but I got trouble with encryption as said in bug http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21303 Is there anybody who did a patch to correct the code of the version 0.20.5 to avoid embed font to be destroyed by encryption ? If no, is it easy for a basic java developper to do the back port from the dev branch to the maintain branch code ? If yes, I could perhaps ask my boss to give me few hours to do it... perhaps. If no, I will try the iText post process. Cedric. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Base font and russian
Hello, At first, thanks to the dev for this wonderfull tools. I need to generate a document in english, french, german and russian. All the text are encoded in utf-8. Everything is fine except for russian. I already read the thread of Nuno Lopes (generating PDFs in non-english august 08) and I have a question : Why should I change fop configuration to use base font ? I read on http://www.cl.cam.ac.uk/~mgk25/unicode.html#fonts that fonts that come with X11 covers all European characters (Latin, Greek, Cyrillic, intl. phonetic alphabet, mathematical and technical symbols, in some fonts even Armenian, Georgian, Katakana, Thai, and more). Does fop use the X11 font ? In fop configuration it says that fop need X11 to be installed. If not, which font does fop is using ? If yes why the fop servlet doesn't found the cyrillic char and display ? I don't want to use special font and embed it in the pdf. Base font should be enough. Russian pdf created with Acrobat are well displayed on the client computer, so I should be able to use standard font with fop. Config : fop 0.20.5 in a customized servlet based on the exemple servlet, running on a Apache Tomcat/5.0.16 on Apache Tomcat/5.0.16.

fop image path with tomcat (servlet, baseDir)
Hello, I have a problem with servlet : no image are found. Fop is working fine (thank you to the dev) to convert my xml to pdf from command line. For performance reason, I am trying to do the same with Tomcat. I am using fop 0.20.5rc3 from cvs, Tomcat 4.1, java 1.4.1. For the test I am on win 2000 and after I will set up a production environment on a linux box. The build script did well the job. I copy the fop.war in the Tomcat webapps subdir and test with a fo file and a xml/xsl files, the PDF was render with no trouble exept the images. In Tomcat window, I saw fop who complain about image path : [ERROR] Error while creating area : Error with image URL: images\logo_acro.gif ( Le chemin d'accÞs spÚcifiÚ est introuvable) and no base URL is specified In the fo file, the src for image is relative to current dir : fo:external-graphic height=15mm width=44mm src=images/logo_acro.gif/ I copy the images dir in webapps\fop but fop did not found it. I tried to call directly the image from the browser and I got a servlet error page FopServlet Error No 'fo' request param given. with the following error in the logs : 2003-04-30 15:42:57 StandardContext[/fop]: Mapping contextPath='/fop' with requestURI='/fop/fop/images/logo_acro.gif' and relativeURI='/fop/images/logo_acro.gif' 2003-04-30 15:42:57 StandardContext[/fop]: Trying exact match 2003-04-30 15:42:57 StandardContext[/fop]: Trying prefix match 2003-04-30 15:42:57 StandardContext[/fop]: Trying extension match 2003-04-30 15:42:57 StandardContext[/fop]: Trying default match 2003-04-30 15:42:57 StandardContext[/fop]: Mapped to servlet 'Fop' with servlet path '/fop/images/logo_acro.gif' and path info 'null' and update=true So, it's look like a miss configuration of Tomcat but I don't know how and where I should set it up. I have installed everything with default value (except debug level). The page http://xml.apache.org/fop/embedding.html is talking about baseDir but how do I set it up or find it's absolut path ?

RE: external-graphic image resolution
The solution I use is to set the image size 3 time less than the real size. It works fine. -Message d'origine- De : Dan Check [mailto:[EMAIL PROTECTED] Envoyé : mardi 22 avril 2003 00:39 À : [EMAIL PROTECTED] Objet : fo:external-graphic image resolution Hi, I've been having some trouble displaying fo:external-graphic jpgs with resolutions higher than 72 dpi. The documentation seems to indicate that FOP doesn't currently support resolutions higher than 72 dpi. Has anyone found a way around this limitation? I'd happily hack my version even if it meant losing all other image functionality, if it would mean I could place images at a resolution higher than 72 dpi. Has this been successfully attempted? If not, is there a thread somewhere describing the difficultly of doing so?
