Some problems in the construction of Java environment

1.http://www.eclipse.org/webtools/eclipse official website, SE, EE direction is two different eclipse

2.tomcat is a plug-in for Eclipse and requires additional downloads

Tomcatplugin Installation

In http://www.eclipsetotale.com/tomcatPlugin.html#A3 download the latest version, I downloaded the tomcatpluginv3.3.1.zip
After extracting, move the Com.sysdeo.eclipse.tomcat_3.3.1.jar file to the Eclipse installation folder plugins, eclipse will automatically recognize and display on the toolbar

The Tomcat installation path needs to be set for the first time:

This allows you to turn tomcat on or off

Another: Tomcat user information can be modified:

The contents are as follows:

<tomcat-users>
<!--role Rolename= "Tomcat"/>
<role rolename= "Role1"/-->
<role rolename= "Admin-gui"/>
<role rolename= "Manager-gui"/>
<role rolename= "Manager-script"/>
<role rolename= "MANAGER-JMS"/>
<role rolename= "Manager-status"/>
<user username= "Tomcat" password= "123456" roles= "ADMIN-GUI,MANAGER-GUI,MANAGER-SCRIPT,MANAGER-JMS, Manager-status "/>
<!--user Username= "both" password= "Tomcat" roles= "Tomcat,role1"/>
<user username= "Role1" password= "Tomcat" roles= "Role1"/-->
</tomcat-users>

This will have all the administrator privileges.

4.J2EE SDK provides some packages for the development direction of the Java EE
