my xhtml is

 <h:form id="ibform">      <p:commandbutton value="yazdır" ajax="false"  action="#{islemibitenlerbean.run_rpr('pdf')}"  icon="ui-icon-print" immediate="true"/> </h:form>

backing bean (conversation scope)

public void run_rpr(string tip) throws ioexception, jrexception, classnotfoundexception, sqlexception {     hashmap m = new hashmap();     m.put("belgeno", selectedbelge.getbelgeno());     reports.preparetreport(raporturu.pdf, "reports//rapor//onaybelgesi.jrxml", "onay belgesi", m); }

public void preparetreport(raporturu tur, string filepath, string filename, hashmap jasperparameter) throws jrexception, ioexception, classnotfoundexception, sqlexception {     connection connection;     class.forname("oracle.jdbc.oracledriver");     connection = drivermanager.getconnection("jdbc:oracle:thin:@--------", "----", "******");     jasperreport jasperreport;     jasperreport jasperreportsub;     jasperprint print;      facescontext faces = javax.faces.context.facescontext.getcurrentinstance();     httpservletresponse response = (httpservletresponse) faces.getexternalcontext().getresponse();     servletcontext servletcontext = (servletcontext) faces.getexternalcontext().getcontext();     string jrxmlfile = servletcontext.getrealpath("/") + filepath;//raporumuzun yolu     jasperdesign jasperdesign = jrxmlloader.load(jrxmlfile);     jasperreport = jaspercompilemanager.compilereport(jasperdesign);      print = jasperfillmanager.fillreport(jasperreport, jasperparameter, connection);     byte[] outdata = jasperexportmanager.exportreporttopdf(print);     bytearrayoutputstream rrtreport = new bytearrayoutputstream();     servletoutputstream out = null;      switch (tur) {         case pdf:              response.setcontenttype("application/pdf");             response.setheader("content-disposition", "attachment; filename=" + filename + ".pdf");             response.getoutputstream().write(jasperexportmanager.exportreporttopdf(print));//web sayfamızdan raporu çıkarttık             faces.responsecomplete();             break;      }
