I was trying to run a report I created and this my JSP:

<%@ page errorPage="error.jsp" %>

<%@ page import="dori.jasper.engine.*" %>

<%@ page import="dori.jasper.engine.util.*" %>

<%@ page import="dori.jasper.engine.export.*" %>

<%@ page import="java.util.*" %>

<%@ page import="java.io.*" %>

<%@ page import="java.sql.*" %>

<%@ page import="java.awt.*" %>

<%

String driver = "sun.jdbc.odbc.JdbcOdbcDriver";

String connectString = "jdbc:odbc:MQIS";

String user = "Administrator";

String password = "";

Class.forName(driver);

Connection conn = DriverManager.getConnection(connectString, user, password);

File reportFile = new File(application.getRealPath("/reports/agents.jasper"));

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

Map parameters = new HashMap();

parameters.put("ReportTitle", "Agents Statistics");

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

conn

);

JRHtmlExporter exporter = new JRHtmlExporter();

StringBuffer sbuffer = new StringBuffer();

Map imagesMap = new HashMap();

session.setAttribute("IMAGES_MAP", imagesMap);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);

exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap);

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "image.jsp?image=");

exporter.exportReport();

%>

My agents.xml compiled fine and there is an agents.jasper file. But when I try running it in Tomcat using the above jsp I get this error. Please help.

JasperReports encountered this error :
