Hi to All, 
I got same error while running the report in tomcat. Actually my report is taking long time to get huge data from database. I think in order to store that data inside RAM it needs a lot of space. I am using cross tabbing inside my report. I adjusted the tomcat setting like 
 
Java 
Initial memory pool : 200MB 
Maximum memory pool : 1024MB 
 
My system configuration is 
 
2.44 GHz Intel P4 processor, 
1.25 GB of RAM, 
Windows XP SP2. 
Tomcat 6.0, 
JVM 1.6.0_22 
Birt 2.6 
 
After adjusting the tomcat setting there is no error but i getting a blank report. 
 
What i have to do? Pls hlp me. 
 
Thanks in advance,
