Skip to main content

A minor error which could spent you a few hours("" vs )

           
Did you see the difference between
  <c:set var="var1">""</c:set>

  and

  <c:set var="var2"></c:set> ?

The 1st one in Java is something like
String var1  = " \"\"";

and the later one is like,
String var2 = "";

So, if you try to compare   var1 with empty, it will retur false as \"\"  is not empty.

Cheers,

Live - solving the jasper report out of memory and high cpu usage problems

I still can not find the solution. So I summary all the things and tell my boss about it. If any one knows the solution, please let me know. Symptom: 1.        The JVM became Out of memory when creating big consumption report 2.        Those JRTemplateElement-instances is still there occupied even if I logged out the system Reason:         1. There is a large number of JRTemplateElement-instances cached in the memory 2.     The clearobjects() method in ReportThread class has not been triggered when logging out Action I tried:      About the Virtualizer: 1.     Replacing the JRSwapFileVirtualizer with JRFileVirtualizer 2.     Not use any FileVirtualizer for c...
