I pretty sure that the problem is the BarcodeMaker.java class in the oraclebarcode.jar. I got the barcode example to work locally (on Windows XP) in reports builder, but I couldn't run it in our webApp on a Solaris appServer. However, I was actually just doing the barcode example to learn how to display gantt charts in a report. So I wrote a simple java class called GantChartTest that uses the JFreeChart API to create a gantt chart as a jpg. I followed the bar code example almost exactly and my gantt charts did show up on the Solaris appServer. Here's my imagefilename function:
function ImageFilenameFormula return VarChar2 is
myFileName varchar2(500);
result varchar2(500);
thePhase VarChar2(50) := :phase;
estStartDate VarChar2(50) := :est_start_date;
estEndDate VarChar2(50) := :est_end_date;
wipActualStartDate VarChar2(50) := :wip_actual_start_date;
wipActualEndDate VarChar2(50) := :wip_actual_end_date;
begin
myFileName := srw.create_temporary_filename;
GantChartTest.createGanttChart(globals.bcobj, thePhase, estStartDate, estEndDate, wipActualStartDate, wipActualEndDate, myFileName);
return(myFileName);
end;
