Cannot connect to X11 window exception
2003-02-24 12:05
I'm using JasperReports on the server side (weblogic server) to generate report for a webapp. I got the following exceptions:

java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

The code I used to fill report in my sevlet is like:

File reportFile = new File(reportFileName);
JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());
Map parameters = new HashMap();
parameters.put("BaseDir", reportFile.getParentFile());
parameters.put("StartingTime", new Long(start.getTime()));
parameters.put("EndingTime", new Long(end.getTime()));
parameters.put("StartingTimeString", "Starting Time: "+startStr);
parameters.put("EndingTimeString", "Ending Time: "+endStr);
parameters.put("MaxRowNums", "300000");

Connection conn = DBUtils.getConnection();

JasperPrint jasperPrint = JasperFillManager.fillReport( jasperReport,
parameters,
conn
);


Thanks,
Kevin

I am also having this problem when trying to generate a report in HTML format, when I try to generate the report for PDF or Excel I get a different NoClassDefFoundException on JRFiller.java line 109.

I wasn't aware of needing to configure any displays on the server to generate reports, I'm going to reread the documentation to see if there's any mention made.

Please see the previous thread on this issue at http://sourceforge.net/forum/message.php?msg_id=1870792. I followed Rick Sperko's suggestion and used PJA to bypass the issue. I have to add two additional sys property settings to make it work:

-Djava2d.font.usePlatformFont=false
-Djava.awt.fonts=<path_to_your_jre_lib_fonts>
