My Tomcat server is on Solaris and I get the same exception but it appears sometimes and when I restart a tomcat, reports started working fine.


I havent set java.awt.headless=true;


My tomcat version is 5.5

and my jasper reports version is 3.0


Please let me know how can reproduce this problem everytime and how can I fix.
