[NullPointerException on JRBaseFiller]

One more clue, the report run well if it have only 1 page and throw Null Pointer Exception when it have more than 2 pages, hope this help to figure out the root cause.

[NullPointerException on JRBaseFiller]

Just add more info that I have upgarded to jasper 6.0.0. I still got the same error at DelayedFillActions.java:525.

[NullPointerException on JRBaseFiller]

I still got NullPointerException, but it happen in DelayedFillActions.java (line 525). I noticed that we have another exception: java.lang.InterruptedException. Below is the full log:

[NullPointerException on JRBaseFiller]

Thanks nthapa for the suggestion, but it does not help. I have tried to upgrade to latest version (5.6.1) and still got the same error.

[So many instance of JRTemplatePrintText, SimpleTextFormat and JRTemplatePrintFrame]

Hi all,

I'm troubleshuting the RAM usage of jasper library (using jmap -histo) and realiza that there are so many instances of JRTemplatePrintText, SimpleTextFormat and JRTemplatePrintFrame:

 num     #instances         #bytes  class name

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

   1:       7034450      844134000  net.sf.jasperreports.engine.fill.JRTemplatePrintText

  13:         49949        7594672  <constMethodKlass>

....................

 

Can anyone explain for me why we need to use so many these duplicated instances? What is the meaning of them? I think it should be small (around 1-100 instances) since I only have some templates.

Thanks,

Nam Dam
