Hi Friends

I have Created and Application with Db2 database.

My Application is Displaying Data through <Webuijsf:table>



when data is small in table then it woks Properly.

But when my data exceeds( i.e. 50000 or more ), then it gives Java Heap Size problem.



I have checked it On both servers :

Tomcat -- it does not display any page even at single time.

Glassfish -- it give error after some time. i.e. after 3-4 clicks or refresh of table.



Trace of problem is as given below --

Please specify the solution for my problem.

Probably you need to increase the heap space that glassfish allocates.
In your jvm options, increase the Xmx

-Xmx512m
