是否需要在用户中为tomcat设置CATALINA_HOME变量

Question

I am newbie for the server side programming servlet. I have written my servlet code using notepad++. I have set my JAVA Path and Tomcat Path as follows:

I am somewhat confused by reading few articles on site. Is it necessary to set the environment variables JAVA_HOME and CATALINA_HOME under user variable or the servlets can be just run by setting PATH and CLASSPATH under system variable.

Please guide me have i set the following environment variables correctly:

Under user variable

• Variable name: CATALINA_HOME

• Variable value: C:\\Program Files\\Tomcat;

• Variable name: JAVA_HOME

• Variable value: C:\\Program Files\\Java\\jdk;

Under system variable

• Variable Name: CLASSPATH

• Variable Value: C:\\Program Files\\Java\\jdk\\lib\\tools.jar;C:\\Program Files\\Tomcat\\lib\\servlet-api.jar;

• Variable Name: Path

• Variable Value: C:\\ProgramData\\Oracle\\Java\\javapath;C:\\Program Files\\Java\\jdk\\bin;C:\\Program Files\\Java\\jre\\bin;%CATALINA_HOME%\\bin;
