i'm developping struts2 app,and want show generated report on browser. i've succefully generate report on disk.but want see @ browser.here code.

my index.jsp

<body> <a href="html.action">reporting</a> </body>

my action databeanlist

public class databeanlist extends actionsupport {        public arraylist<databean> getdatabeanlist() {      arraylist<databean> databeanlist = new arraylist<databean>();        databeanlist.add(produce("manisha", "india"));       databeanlist.add(produce("dennis ritchie", "usa"));       databeanlist.add(produce("v.anand", "india"));       databeanlist.add(produce("shrinath", "california"));       databeanlist.add(produce("issam", "casa"));        return databeanlist;    }     /**     * method returns databean object,     * name , country set in it.     */    private databean produce(string name, string country) {       databean databean = new databean();       databean.setname(name);       databean.setcountry(country);       return databean;    }   public void exporte(){  string sourcefilename = "d://test/workspace/ztest/webcontent/reports/jasper_report_template.jasper";                // + "test/jasper_report_template.jasper";         //d:\test\workspace\ztest\webcontent\reports           string printfilename = null;           databeanlist databeanlist = new databeanlist();           arraylist datalist = databeanlist.getdatabeanlist();           jrbeancollectiondatasource beancoldatasource =              new jrbeancollectiondatasource(datalist);            map parameters = new hashmap();           try {              printfilename = jasperfillmanager.fillreporttofile(sourcefilename,                 parameters, beancoldatasource);              if (printfilename != null) {                 /**                  * 1- export pdf                  */                 jasperexportmanager.exportreporttopdffile(printfilename,                       "d://sample_report.pdf");                }           } catch (jrexception e) {              e.printstacktrace();           }        }     }

first of export report stream, that:

jasperprint jasperprint = jasperfillmanager.fillreport(jasperreport,             parameters, beandatasource); jasperexportmanager.exportreporttopdfstream(jasperprint, out);

then convert output stream input stream , assign inside action inputstream variable getters/setters. , configure action use stream result.

<action ...>   <result type="stream">     <param name="inputname">inputstream</param>     <param name="contenttype">application/pdf</param>     <param name="contentdisposition">attachment;filename="report.pdf"</param>   </result> </action>
