JasperFillManager.fillReport hangs (3.7.2)

[kvasov]

Hi,

I've got a problem with JasperFillManager. it hangs after several invocations of fillReport method. I'm not doing anything complex. it's a simple one-page report where around 15 parameters are passed as a HashMap.

 

that's how I create jaspre report:

 

        try {
            resourceAsStream = MarginCallManager.class.getClassLoader().getResourceAsStream("report.jrxml");
            jr = JasperCompileManager.compileReport(resourceAsStream);
            LOG.info("compiled report for jasper");
           
        } catch(JRException e) {
            LOG.error("failed to load jasper report", e);
        } finally {
            try {
                if(resourceAsStream != null) {
                    resourceAsStream.close();
                }
            } catch (Exception e) {
                LOG.warn("failed to close report stream for jasper", e);
            }
        }
 

 

so this instance is shared for all invocations.

 

this is how I fill report and create a PDF:

 

        try {
            Map<String, String> values = new HashMap<String, String>();
            ...
           
            ByteArrayOutputStream os = new ByteArrayOutputStream();
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, values, new JREmptyDataSource());     
            LOG.info("filled report for jasper");
            JasperExportManager.exportReportToPdfStream(jasperPrint, os);
            LOG.info("created pdf for Id=" + Id);
            return os.toByteArray();

        } catch (JRException e) {
            LOG.error("error creating pdf file for " + marginCallId, e);
        } catch (Exception e) {
            LOG.error("unknown error loading margin call for " + marginCallId, e);
        }
 

I'm using jasper reports version 3.7.2 and it's running under Tomcat6. Calls to create a PDF report are actually RMI calls. After several calls it hangs in JasperFillManager.fillReport method and after that no reports are created. It just stops working. It happens under really light load, like 1 invocation per hour.

 

It's quite frustrating as there are no exceptions, no signs of failure, it just hangs.

I'd really appreciate any advice or help.

Initially I was creating JasperReport instance for each invocation but had the same problem.

 

Thanks,

Vladimir

Try to enable debug logging for JasperReports (e.g. with log4j) and see whether anything relevant shows in the log file at the time of the problem.

Hi Lucian,

 

thank you for the hint. I'll try changing log4j level. Unfortunately can't do it now as the environment where this problem occurs is now closed for changes.

I had the same problem. After reviewing my code and my report I didn't find anything. However, after checking the dependecies I found that I had two log4j  jars:

log4j-1.2.12.jar

log4j-1.2.14.jar

The one producing the situation is log4j-1.2.12.jar, so check your dependecies and remove the log4j-1.2.12.jar one.

Hope it helps.

Hi Tsunami,

thanks for suggestion - I checked dependecy tree - we use log4j 1.2.15 (plus sl4j and log4j extras)

btw we moved to another reporting library since then.

Hello,

First of all i'm sorry for my english.

I have the same problem, please let me know if you solve this.

Thanks you!...

Hi Ghitman,

No, unfortunately I didn't have enough time to work on mysteries like this one, so we decided to use BFO to generate PDF reports. Which is a shame as I had good experience with Jasper reports in the past.

 

thanks

Hi,

I have a similar problem and i've posted it as follows

 

"jasperFillManager.fillreport cannot hold huge data coming from a hash map"

Please guide me to solve this issue.

Thank you
