i have written java program httprequest using httpurlconnection download/upload file of format(xml, image, documents) specific server using it's authentication api-key. program works fine. need upload java program file in website cloud service , need able download file server using java program file uploaded website. how can it? 1 thing make sure java program wrote not web application, java program.

for downloading file create function follows: 

private void exportexcel(httpservletresponse response, hssfworkbook workbook) throws cpaserviceexception{     try{     response.reset();     response.setcontenttype("application/vnd.ms-excel");     response.setheader("content-disposition", "attachment;filename=" + workbook.getsheetat(0).getsheetname()+".xls");     workbook.write(response.getoutputstream());     }catch(ioexception e){         throw new cpaserviceexception(cpaconstants.application_general_error);     } }

then call function as:

@requestmapping(value = "/"+controllerpaths.get_excel_for_common_process_system_report, method = requestmethod.get) @responsestatus(httpstatus.ok) public void getexcelforcommonprocesssystemreport(httpservletrequest request, httpservletresponse response, cpareportfilterdto filterdto) throws exception{     exportexcel(response, reportservice.generateexcelforreport(filterdto)); }
