I googled it, and find several methods, but they are different,
some people told me that i only need to create the env variable named “CATALINA_HOME”,
BUT some told me to create four variables: CATALINA_HOME, CATALINA_BASE, CATALINA_TMPDIR
and TOMCAT_HOME.
which one is right? thanks in advance.
if your using Eclipse i would suggest you to run it as an external server,all you have to do is unzipping it in any locating you want and in Eclipse add an new server that point to its location,its is easy work with as an external server
