Re: fop + servlet + multisession

[Gian Piero Bottini]

Now I'll try to encrease the debug level...(by the way how can I do that??)
Now my output in the dos-Tomcat window is this ( I'm creating a pdf document
99 pages long):

[INFO] [99]
[INFO] [86]
[INFO] [87]
[INFO] [88]
[INFO] Parsing of document complete, stopping renderer
[INFO] [89]

and it seems blocked but I don't know.....
but sometimes it works fine...very strange...
and sometimes the servlet is called twice( why??)

This is the code:

.........
try{
           XSLTInputHandler input =
                    new XSLTInputHandler(xmlFile,
                                       xslFile);
            renderXML(input, response);

      } catch (Exception ex) {
                 ex.printStackTrace();
      }
.....................

public void renderXML(XSLTInputHandler input,
                          HttpServletResponse response) throws
ServletException {
        try {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            response.reset();

            // questa riga è necessaria per IE che forse non capisce il
SetContentType()
            response.setHeader("Content-Disposition","inline; filename=" +
"Report1.pdf");
            response.setContentType("application/pdf");

            org.apache.fop.apps.Driver driver = new
org.apache.fop.apps.Driver();

            driver.setRenderer(org.apache.fop.apps.Driver.RENDER_PDF);
            System.gc();
            driver.setOutputStream(out);
            driver.render(input.getParser(), input.getInputSource());
            System.gc();
            System.out.println("stop render");
            byte[] content = out.toByteArray();
            response.setContentLength(content.length);
            response.getOutputStream().write(content);
            response.getOutputStream().flush();
        } catch (Exception ex) {
            throw new ServletException(ex);
        }
    }

Thanks a lot
Regards
