Did FOP finish processing? Run FOP in debug mode and analize debug messages.

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

Gian Piero

ciao Gian Piero,

this is the snippet to set the log level to debug
--
//Setup logger
Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_DEBUG);
driver.setLogger(logger);
MessageHandler.setScreenLogger(logger);
--


and sometimes the servlet is called twice( why??)
it's a bug of  IE 5.0/5.5



hope this help

fabrizio

Thanks  a lot 
but sometimes (with 3 session of IE)
tomcat  stops without exception or without particolar debug messages...
Somebody have any ideas??
Could be a memory problem??

Regards
  Gian Piero
