Servlet can't find the specified path

Hi,
I am having problem calling Jasper report from servlet.

When I run the following program in main method, it works fine.

public class RolesReport
{
    public static void main(String[] args) throws ClassNotFoundException, JRException, SQLException
    {
        Class.forName("com.mysql.jdbc.Driver");
        String mysql = "jdbc:mysql://localhost/databaseName?user=root&password=root";
        Connection connection = DriverManager.getConnection(mysql);
        JasperReport jasperReport;
        JasperPrint jasperPrint;        
        HashMap jasperParameter = new HashMap();
        jasperReport = JasperCompileManager.compileReport("reports/report.jrxml");
        jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, connection); 
        //displays the report
        JasperViewer.viewReport(jasperPrint);
        
        connection.close();
    }
}

But when do public void displayReport(), and calls it from a servlet,

public class RolesReport
{
    public void dailyReport() throws ClassNotFoundException, JRException, SQLException
    {
        Class.forName("com.mysql.jdbc.Driver");
        String mysql = "jdbc:mysql://localhost/databaseName?user=root&password=root";
        Connection connection = DriverManager.getConnection(mysql);
        JasperReport jasperReport;
        JasperPrint jasperPrint;        
        HashMap jasperParameter = new HashMap();
        jasperReport = JasperCompileManager.compileReport("reports/report.jrxml");
        jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, connection); 
        //displays the report
        JasperViewer.viewReport(jasperPrint);
        
        connection.close();
    }
}

I got an Exception that

net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: reports\report.jrxml (The system cannot find the path specified)

Any Idea why I am getting an exception that file not found?

try to use the request.getRealPath("/")
getServletContext().getRealPath("/");
this.getClass().getClassLoader().getResource("").getPath();
and analyze and reorganize it
