WAS : express, base, ND

Express is like tomcat, only WAR no EJB module. Furthermore single instance for dev-prod to simplify the deployment.

Base, able to handle EJB module. Not support cluster and only support server1 Appserver.
Server1 cant be started or stopped using ISC.

ND, support cluter and multi app servers.

Note :
About ISC :
there is a isclite.ear module in config/cells/node/applications/ if ISC is installed.
In base, you may not install ISC, nor defaultapp (snoop/hello), nor sampleApp(plant)
But you are auto installing the ivtApp.ear and query.ear.
IvtApp.ear is used during the firstStep to verifiy instalation result, like start hem and test the ports.

About trial period:
can be tricked by changing the date of the OS.
