Where is Eclipse deploy web application Tomcat

By default Eclipse deploys web application to a internal plugin folder called wtpwebapps, which is located in the following directory :

{Your_Workspace}/.metadata/.plugins/org.eclipse.wst.server.core/tmp{number}/wtpwebapps
#Example 1 - Windows
C:\Users\mkyong\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps
#Example 2 - Mac OSX
/Users/mkyong/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps
