Struts2 + JasperReport Application 2: jasperReport Web Forms Printing

Be jasperReport design document and compile files on webRoot the following jasper folder below.

public class Person {
        private String person_Id;

        private String person_name;

        private String person_age;

        private String person_address;
public class PersonService {
        public List<Person> getAllPerson() {
                List<Person> perList = new ArrayList<Person>();
                perList.add(new Person("101", " Klein  ", "22", " Hubei  "));
                perList.add(new Person("102", " Smith, John  ", "21", " Hunan  "));
                perList.add(new Person("103", " Paul Lee  ", "23", " Jiangsu  "));
                perList.add(new Person("104", " Wangwu  ", "22", " Shanghai  "));
                return perList;

Construction of our applet is as follows:

public class JRPrinterApplet extends javax.swing.JApplet {
        private URL url = null;
        public void init() {
                String strUrl = getParameter("REPORT_URL");
                if (strUrl != null) {
                        try {
                                url = new URL(getCodeBase(), strUrl);//  From the HTML parameters in a report URL
                                // System.out.println("url=" + url.toURI());// If the servlet path
                        } catch (Exception e) {
                                StringWriter swriter = new StringWriter();
                                PrintWriter pwriter = new PrintWriter(swriter);
                                JOptionPane.showMessageDialog(this, swriter.toString());
                } else {
                        JOptionPane.showMessageDialog(this, "Source URL not specified");
        public void start() {
                if (url != null) {
                        try {
                                Object obj = JRLoader.loadObject(url);//  Send an object request, obtain JasperPrint object
                                JasperPrintManager.printReport((JasperPrint) obj, true);//  Call the method to print the JasperPrint object
                        } catch (Exception e) {

Structure of our action is as follows:

public class JRPrintAction extends ActionSupport {
        public String execute() throws Exception {
                File reportFile = new File(ServletActionContext.getRequest()
                Map<String, String> parameters = new HashMap<String, String>();
                parameters.put("year", "2009");
                parameters.put("unit_mc", " Wuhan XX technology co., Ltd.  ");
                List<Person> personList = new PersonService().getAllPerson();
                JasperPrint jasperPrint = null;
                JasperReport jasperReport = (JasperReport) JRLoader
                jasperPrint = JasperFillManager.fillReport(jasperReport, parameters,
                                new JRBeanCollectionDataSource(personList));
                }catch (Exception e) {
                        throw e;
                if(null != jasperPrint){
                        HttpServletResponse response = ServletActionContext.getResponse();
                        ServletOutputStream ouputStream = response.getOutputStream();
                        ObjectOutputStream oos = new ObjectOutputStream(ouputStream);
                return null;

struts.xml configuration is as follows:

<action name="jrPrint"
                        <result name="success">/index.jsp</result>

web.xml configuration is as follows:


Be JRPrinterApplet compile files on webRoot the following applet the following folder

Page call is as follows:

<input type="button" value=" Print  " name="button1">

        function print(){
                var url = "jrPrint.action";
                document.write('<APPLET CODE = "JRPrinterApplet.class" CODEBASE = "applets" ARCHIVE = "jasperreports-3.5.2-applet.jar,commons-logging-1.0.2.jar,commons-collections-2.1.jar" WIDTH = "0" HEIGHT = "0">');
