Hello, when I try to make a War file I have always the same problem: java.lang.OutOfMemoryError
Created attachment 15605 [details] ide.log
You are saying that you get the OOME when building WAR file, not when deploying, correct? In 40 we use ant to build WAR files so the same OOME will not happen. You can also try increasing max memory size by the -J-Xmx240m (replace 240 by whatever you want) in ide.cfg file.
