In my $TOMCAT_HOME/conf/server.xml I put this near the bottom:
...
I was need ROOT context in Tomcat/IntelliJ, so in server.xml in Host tag, add specific Context :
In intelliJ 11.1.5, in Server tab panel check box "Deploy applications configured in Tomcat instance", IntelliJ will copy server.xml in folder deployment :
C:\Users\{Username}\.IntelliJIdea11\system\tomcat\Unnamed_Product_2\conf"
Now I can access to resources in Root domain, by example crossdomain.xml :
http://localhost:8080/crossdomain.xml
