This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
We have a production application deployed in JBoss. Currently all screens have a functionality to export xls files. If the number of rows are above 100,000, then we cannot generate the xls file. So we made a plan, to find out the size of List<Object>, if the size is more than 600 MB, restrict the user to create xls file.
Is there a way to find out the memory size of object in Jboss ?
