Jasper Report with POJO Datasource

Jasper Report with POJO Datasource

Following codes should be use as client code. can be placed on your controller class.
ReportUtil class is the library developed by me. You can use it as "ReportUtil.createreport".
First Set classpath in Jasper report tools -->option -->add JAR
Second get fields from class.Click datasource icon,click javabean datasource tab,enter package name included class name.

 private final static String PATH_DOC="../server/default/deploy/complain-documents.war/report/";
 private final static String PATH_DOC_REPORT_SOURCE="../server/default/deploy/complain-documents.war/report-source/complainreport.jasper";
 private final static String REPORT_NAME="complain_log_";

Following code is the client code.code pass the values to method. Values includes parameters dataset and jasper file name.

 
   try {
    HashMap parameters = new HashMap();
    parameters.put("fromDate", viewdatestart);
    parameters.put("toDate", viewdateend);
    parameters.put("username", req.getUserPrincipal().getName());
    String pathReportJasperFile=PATH_DOC_REPORT_SOURCE;
    String part2="-"+new Date().getTime();
    String pathReportPDFFile=REPORT_NAME+part2+".pdf";
    ReportUtil.createreport(listViewLog, pathReportJasperFile, PATH_DOC+pathReportPDFFile,parameters);
    model.addAttribute("fileTemp", pathReportPDFFile);
   } catch (Exception e) {
    e.printStackTrace();
   }
