Compile a JasperReport

Question

Hi,
I have a report on Ireport.
I'm trying to compile, fill and run my report while my application is running but I get some errors.
This is my code:
//code
JasperDesign jDesign = JasperManager.loadXmlDesign(fileName);
JasperReport jReport = JasperManager.compileReport(jDesign);
Map parameters = new HashMap();
String cotiza = new String ("87872");
parameters.put("NumCotizaP",cotiza);
JasperPrint jPrint = JasperManager.fillReport(jReport, parameters, getConnection());
JasperManager.printReportToPdf(jPrint);
if (jPrint != null) {
JasperViewer.viewReport(jPrint, false);
//code
My error is this:
Error -> net.sf.jasperreports.engine.JRException: Invalid byte 1 of 1-byte UTF-8 sequence.
What can I do? IT'S REALLY URGENT!!!
I really need to compile and fill my report. Actually I already can open the report with the JasperViewer.
Thanks in advance.

Answer 1

I guess this is what I was trying to explain before. You cannot use JasperViewer in the normal JSC/JSF senario.
JasperViewer runs on a java runtime, when using JSC/JSF you are only sending web pages to the client. In the normal JSC/JSF senario you are only using the Runtime on the server (hence your experience). That said there are ways to make the report viewable in JasperViewer on the client, but its much harder. We have done this using an java applet.
You have 2 options:
1. Send the report to the user in PDF form (or Excel or text or html, or whatever jasperReports provides). See my example http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=50166
2. Use an applet to bring up the JasperViewer, This will take you a long time to develop.
