Hi all, Please help with my encountered problem! I have a master report with different sub-reports created with iReport 1.3.2. The master report can be run with the pdf engine inside iReport. But then when i put the jasper files to my Tomcat application and called the master.jasper via a servlet, the following error comes out. Class not found when loading object from file: /usr/local/tomcat/webapps/motor/master.jasper All the jasper files are put in /usr/local/tomcat/webapps/motor directory. And here are the coding in servlet Code: import javax.naming.*; import javax.sql.*; import net.sf.jasperreports.engine.*; import net.sf.jasperreports.engine.export.*; import java.util.*; import java.io.*; import java.sql.*; import javax.servlet.*; import javax.servlet.http.*; //import dori.jasper.engine.*; public class PrintForm extends HttpServlet { private ServletContext application; public void init(ServletConfig config) throws ServletException { super.init(config); } public void destroy() { } protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { application = getServletConfig().getServletContext(); File reportFile = new File(application.getRealPath("/master.jasper"«»)); BufferedReader input = new BufferedReader(new FileReader(reportFile)); String connstr = input.readLine(); input.close(); Map parameters = new HashMap(); parameters.put("quono", request.getParameter("quono"«»)); parameters.put("clauses", request.getParameter("clauses"«»)); parameters.put("namedDriver_percentage", request.getParameter("namedDriver_percentage"«»)); parameters.put("travelToChina_percentage", request.getParameter("travelToChina_percentage"«»)); parameters.put("rebate", request.getParameter("rebate"«»)); parameters.put("loading", request.getParameter("loading"«»)); parameters.put("mib", request.getParameter("mib"«»)); // Get connection to PMDDLIB String DbDriver = "com.microsoft.jdbc.sqlserver.SQLServerDriver"; String DbUrl = "jdbc:microsoft:«»sqlserver://10.168.2.41:1433;databasename=QM_SYS"; String DbUser = "qmsys"; String DbPassword = "it06cyber97"; Connection dbCon = null; Class.forName(DbDriver); dbCon = DriverManager.getConnection(DbUrl, DbUser, DbPassword); byte[] bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, dbCon); response.setContentType("application/pdf"«»); response.setContentLength(bytes.length); ServletOutputStream ouputStream = response.getOutputStream(); ouputStream.write(bytes, 0, bytes.length); ouputStream.flush(); ouputStream.close(); } catch(Exception ioe) { System.err.println(ioe.getMessage()); } } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } } The PrintForm class is put inside /usr/local/tomcat/webapps/motor/WEB-INF/classes Anyone can help? Many thanks, Gloria
