I don't fully understand your question (because of my English) but I thing this would help you:

 

In the doGet or doPost method do something like this:

 

ByteArrayOutputStream baos;

 

JasperExportManager.exportReportToPdfStream(jp,baos);

/* where jp is a JasperPrint object created with the JasperFillManager.fillReport(list of params) method */

response.reset();

response.setContentType("application/pdf");

response.setHeader("Expires", "0");

response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");

response.setHeader("Pragma", "public");

response.setContentLength(baos.size());

 

OutputStream out = response.getOutputStream();

 

baos.writeTo(out);

baos.close();
