java - Jasper report error when exporting report to docx -

-

i'm trying export jasper report .docx file; i'm getting error 

java.lang.classcastexception: java.lang.string cannot cast net.sf.jasperreports.engine.jasperprint

i'm using java develop this.

here code used

public void generatereport2() throws printerexception {  try {   string sourcefilename = "src/pos_bill/esfourreport.jasper"; string printfilename = null; databeanfactory2 databean = new databeanfactory2(); jrbeancollectiondatasource beancoldatasource = new      jrbeancollectiondatasource(databean.generatecollection()); map parameters = new hashmap(); printfilename = jasperfillmanager.fillreporttofile(      sourcefilename,      parameters,      beancoldatasource);   jrdocxexporter exp=new jrdocxexporter();    exp.setparameter(jrexporterparameter.jasper_print,printfilename); exp.setparameter(jrexporterparameter.output_file_name,"src/pos_bill/sample_report2.docx"); exp.exportreport();   } catch (exception e) {  system.out.println(e); }  }

finally found answer!

i removed these 2 lines

exp.setparameter(jrexporterparameter.jasper_print,printfilename); exp.setparameter(jrexporterparameter.output_file_name,"src/pos_bill/sample_report2.docx");

and replaced these

exporter.setexporterinput(new simpleexporterinput(printfilename)); exporter.setexporteroutput(new simpleoutputstreamexporteroutput("src/pos_bill/samplereport2.docx"));

and works finely!
