The problem is that it doesnt say at which line the error occures. I have downloaded the advised digestor from the tomcat site and added the lib file to my webapps/ROOT/WEB-INF/lib/ directory. This creates the same error. Overriding the digestor jar file in the tomcat dir stops tomcat from working. It wont even start!!! I returned the original tomcat digestor jar file back to the common/lib directory and tomcat worked again.

 

This is my code

 

String connectionURL = "jdbc:mysql://localhost:3306/Db";

String userName = "username";

String password = "password";

 

Class.forName("com.mysql.jdbc.Driver");

java.sql.Connection aConnection = java.sql.DriverManager.getConnection(connectionURL, userName, password);

 

File reportFile = new File(application.getRealPath("/BasicReport.xml"));

 

// First, load JasperDesign from XML and compile it into JasperReport

JasperDesign jasperDesign = JasperManager.loadXmlDesign(reportFile.getAbsolutePath());

JasperReport jasperReport = JasperManager.compileReport(jasperDesign);

 

// Second, create a map of parameters to pass to the report.

Map parameters = new HashMap();

parameters.put("ReportTitle", "Basic JasperReport");

parameters.put("MaxSalary", new Double(25000.00));

 

// Fourth, create JasperPrint using fillReport() method

JasperPrint jasperPrint = JasperManager.fillReport(jasperReport, parameters, aConnection);

 

// You can use JasperPrint to create PDF

JasperManager.printReportToPdfFile(jasperPrint, "BasicReport.pdf");

 

// Or to view report in the JasperViewer

JasperViewer.viewReport(jasperPrint);

 

Can anybody help?
