How To Generate A Jasper Study Inwards Java

This tutorial volition conduct y'all inward generating a jasper study inward java.

You need:
1.) Eclipse
2.) iReport - http://community.jaspersoft.com/project/ireport-designer

Steps:
1.) First nosotros quest to utilization a model for our report. For instance nosotros convey a Student model:

public degree Student {  somebody String name;  somebody int age;  somebody String address; } 

2.) We quest to utilization the study inward iReport.
  a.) Create a datasource:
    Factory class=com.czetsuya.jasper.edition.StudentReportBean
    Static method=createBeanCollection

3.) Drag a listing element to the study designer too laid upwardly the information origin to our newly created one. You should come across something like:

4.) Create the StudentReportBean class, the ane that generates the data.

public degree StudentReportBean {   world StudentReportBean() {   }   world static List<student> createBeanCollection() {   List<student> students = novel ArrayList<student>();    Student a = novel Student();   a.setName("Tifa Lockheart");   a.setAge(19);   a.setAddress("Final Fantasy VII");   students.add(a);    Student b = novel Student();   b.setName("Rinoa Heartilly");   b.setAge(19);   b.setAddress("Final Fantasy VIII");   students.add(b);    furnish students;  } } 

5.) And inward our instance a managed edible bean that gets trigger from a ascendancy push clit inward UI.

public void run() throws JRException, IOException {  Collection<student> students = StudentReportBean.createBeanCollection();  JRBeanCollectionDataSource beanCollectionDataSource = novel JRBeanCollectionDataSource(    students, false);   String reportPath = FacesContext.getCurrentInstance().getExternalContext()    .getRealPath("/WEB-INF/classes/StudentReport.jasper");   JasperReport jasperReport;  jasperReport = (JasperReport) JRLoader.loadObjectFromFile(reportPath);   Map<string object=""> params = novel HashMap<string object="">();  JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params,    beanCollectionDataSource);   HttpServletResponse reply = (HttpServletResponse) FacesContext.getCurrentInstance()    .getExternalContext().getResponse();  ServletOutputStream out = response.getOutputStream();     response.setContentType("application/pdf");  response.setHeader("Content-disposition", "attachment; filename=student-report.pdf");    JasperExportManager.exportReportToPdfStream(jasperPrint, out);   out.flush();   out.close(); } 

6.) You should live on able to download the generated study from a browser.
