JasperReports questions


  • Subject: JasperReports questions

I was trying to figure out how to print a 'to many' relationship in JasperReports/iReport (still haven't figured it out), and I noticed that at:

/var/folders/2d/c1m5r3_92rj8y6_xt24c7r7r0000gn/T

there were a ton of 'temp' pdfs. So I started digging into how ERJRUtilities.java creates the pdf and I see it uses

File destFile = File.createTempFile(compiledReportName + System.currentTimeMillis(), ".pdf");

to create the temp file but never releases it with:

destFile.deleteOnExit();

if it does this somewhere else, I cannot find it.

If anyone has any insight on the 'to-many' problem, I am getting tired of rereading the iReport/JasperDataSource documentation.
