JRBaseFiller: error cleaning up virtualizer

2006-02-17 08:19

hello

I use jasperreports1.2.0 in a websphere 5 environnment, in a web application. i've made some load test to simulate 10 users that generates together on report of about 80 pages and i have the exception below

 

JRBaseFiller (cleanup, 313 ) - Error cleaning up virtualizer.

java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFileVirtualizer.makeFilename(JRFileVirtualizer.java:221)

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.fileDispose(JRFileVirtualizer.java:283)

at net.sf.jasperreports.engine.fill.JRFileVirtualizer.cleanup(JRFileVirtualizer.java:310)

at java.lang.ref.Finalizer.access$100(Finalizer.java:14)

at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160)

---------------------------

here is the code i use

virtualizer = new JRFileVirtualizer(5,temp_dir);

parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer);

JasperPrint jasperPrint = JasperFillManager.fillReport(name, parameters, dataSource);

virtualizer.setReadOnly(true);

output = JasperExportManager.exportReportToPdf(jasperPrint);

virtualizer.cleanup();

----------------------

If I test with only one user, there is no such problem. do you have an idea to correct it?

 

regards

Hello

 

The cause of the error was a small bug in JRFileVirtualizer.deregisterObject(JRVirtualizable).

 

A fix has been commited on CVS.

 

To patch the 1.2.0 JRFileVirtualizer, change lines 155-156 to

if (old != null && old != o) {

pagedOut.put(uid, old);

 

Thank you,

Lucian
