dj22 Posted November 24, 2006 Share Posted November 24, 2006 Hi. I have a problem filling reports with jasperReports. I am creating a client-server application running as a servlet under tomcat.While trying to fill the report with data from database i get the following error in the tomcat log: (sorry for the long stacktrace, i tried to emphasize important lines) SEVERE: execute: Error while performing requestorg.apache.xmlrpc.XmlRpcException: Failed to invoke method sqlCreateReport in class

JasperFillManager.fillReport(new File(jasperFile).getPath(), parameters, cdbConn.getConnection()); So it's obviously that a class is missing, but it does not state which one. system:os: debian linuxdb: mysql 4.0.24webserver: tomcat 4.1.10tested with jaspereports version 1.2.5 and 1.2.8 The same application has been successfully tested on 2 other systems (windows xp home sp2 and suse linux 10), so i am sure i included all neccessary libs. Any help is very much appreciated.Thank you in advance.Post edited by: dj22, at: 2006/11/24 09:02 Link to comment Share on other sites More sharing options...
