Hi All:

I am using Icefaces 1.8.2, Jsf 1.1 and JasperReport 3.5.2.
I click a button and it call "testSearch" and should give return a pdf file. Instead nothing happens. There are no errors and no pdf file.
Any help or hint would be greatly appreciated it

public String testSearch() throws Exception
{
try
{
Connection connection;
FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();
InputStream reportStream = context.getExternalContext().getResourceAsStream("WEB-INF/reports/test_report.jasper");
ServletOutputStream servletOutputStream = response.getOutputStream();
ServletContext ctx = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();
String filepath = ctx.getRealPath("/WEB-INF/reports/");
String imagepath = ctx.getRealPath("/WEB-INF/images/test_logo.gif");

HashMap parameterMap = new HashMap();


parameterMap.put("SUBREPORT_DIR", filepath);
parameterMap.put("Test Number", testNumber);
parameterMap.put("Image Path", imagepath);

Properties properties = new Properties();
properties.load(context.getExternalContext().getResourceAsStream("WEB-INF/config.properties"));

String driver = properties.getProperty("jdbc.driver");
String jdbc_url = properties.getProperty("jdbc.url");
String username = properties.getProperty("jdbc.username");
String password = properties.getProperty("jdbc.password");
Class.forName(driver);
connection = DriverManager.getConnection(jdbc_url, username, password);


JasperRunManager.runReportToPdfStream(reportStream, servletOutputStream, parameterMap, connection);

connection.close();

response.setContentType("application/pdf");
servletOutputStream.flush();
servletOutputStream.close();
}
catch(Exception e)
{
log.error("exception message:"+e.getMessage());
}

return "success";
}

Don't try and generate non-HTML documents in JSF code. All you will get is pain. Move the report generation functionality to a plain servlet.
