Hi Guys, this is my very first post here :o) We developed a servlet, running in Tomcat 5.5 container, which consumes XML file and replies with PDF generated document. All works fine on Windows machines. But when we deployed the war achive to the target environment, which is Red Hat Enterprise Linux Server release 5.5 (Tikanga) we discovered, that barcode values, which are usually placed at the bottom of the generated bar codes are not included in the generated PDFs on Red Hat. The we did a bit of googling and found a bunch of good hints: http://www.jaspersoft.com/sites/default/files/jw-presentations/JW11_JasperReports_Tips_And_Tricks_TeodorDanciu%2002.pdf http://mdahlman.wordpress.com/2010/05/28/jaspersoft-v3-7-font-extensions/ http://grysz.com/2010/06/01/use-custom-fonts-in-jasperreports-pdf-exporter/ We use the recent version of Jasper Reports 4.5.1 and I discovered there is already prepared jar file containing font extension jasperreports-fonts-4.5.1.jar. So we put it on the classpath, but without any success. So my question is, if we need to configure something else in reports (all reports use defautl SansSerif font, which is included in the extension). Do we need to specify this somewhere explicitly? Or it is a problem of Red Hat OS? Or Java execution environment on Red Hat? Any clues are very welcome. Tahnk you.
