There's no Java EE in eclipse.

Eclipse is a client-side development tool that does not carry the Java EE jar package and requires containers such as Tomcat to provide this jar.

Eclipse to do the development of the Java EE need to integrate a lot of plug-ins, myeclipse all integrated directly can create a Java EE project
in the case of a problem your project does not have to be put into the Tomcat-webapp folder to publish, imagine a project if the 300M how much time do you spend each time you publish the application? 
The general practice is to create an XML file in \tomcat\conf\catalina\localhost\
file name. xml
<context path= "/project1" docbase= "D:\WorkSpace\project1\webroot"/>

OK so that your project anywhere, as long as you specify in the XML file is good Tomcat will be able to publish the application. 

There's no Java EE in eclipse.
