Hello to all.

if launch action that it creates the report through link HTML the action comes executed two times and the report it is opened in the browser;

I have encounted this problem before, maybe it was caused by the parameters you passed.

I believe a more elegant and less buggy solution is to create a servlet that returns the PDF content directly. Look at the "webapp" sample for a detailed example, there is a PdfServlet.java that shows you how to send PDF content from the servlet (or any other format you choose).

I have put the parameters into session, then the jsp file much like this:

<%@ page import="net.sf.jasperreports.engine.*" %>

<%@ page import="net.sf.jasperreports.engine.export.*"%>

<%@ page import="net.sf.jasperreports.engine.util.*"%>

<%@ page import="java.util.*" %>

<%@ page import="java.io.*" %>

<%@ page import="java.sql.*" %>

 

<%

 

File reportFile = new File(application.getRealPath("/reports/test.jasper"));

 

Map parameters = new HashMap();

 

String param = (String)request.getSession().getAttribute("param1");

 

parameters.put("stuffid",param);

 

Connection conn = null;

 

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();

 

String url="jdbc:oracle:thin:@192.168.0.200:1521:xxxx";

 

String user="xxxx";

 

String password="xxxx";

 

conn = DriverManager.getConnection(url,user,password);

 

byte bytes[] = JasperRunManager.runReportToPdf(reportFile.getPath(),parameters,conn);

 

response.setContentType("application/pdf");

 

//response.setHeader("Content-disposition","attachment; filename=test.pdf" );

 

response.setContentLength(bytes.length);

 

ServletOutputStream ouputStream = response.getOutputStream();

 

ouputStream.write(bytes, 0, bytes.length);

 

ouputStream.flush();

 

ouputStream.close();

 

%>
