Hi,
I'm trying to run a simple JasperReport in Tapestry, but get strange
exceptions:
[java] net.sf.jasperreports.engine.JRException: Errors were encountered
when compiling report expressions class file:
[java] D:\workspace\SAB\simple_1299668551250_924092.java:4: package
net.sf.jasperreports.engine does not exist
[java] import net.sf.jasperreports.engine.*;
[java] ^
[java] D:\workspace\SAB\simple_1299668551250_924092.java:5: package
net.sf.jasperreports.engine.fill does not exist
[java] import net.sf.jasperreports.engine.fill.*;
[java] ^
[java] D:\workspace\SAB\simple_1299668551250_924092.java:18: cannot
find symbol
[java] symbol: class JREvaluator
[java] public class simple_1299668551250_924092 extends JREvaluator
...
I have no problems to run the same report standalone.
Maybe I am completly wrong? I start the report this way:
public StreamResponse onActionFromJasper()
{
try {
JasperReport jasperReport =
JasperCompileManager.compileReport("reports/simple.xml");
System.out.println("1");
//CustomDataSource dataSource = new CustomDataSource();
JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport, new
HashMap(),new JREmptyDataSource());
System.out.println("2");
JasperExportManager.exportReportToPdfFile(jasperPrint,
"reports/simple.pdf");
System.out.println("3");
}catch(JRException e) {
e.printStackTrace();
}
return null;
}
Please help me to understand the way to work with JasperReports + Tapestry
