java - Setting Environment variables for Eclipse IDE launching -


I want to start a project in eclipse, but when I try to start eclipse it is not open . My instructor said that I have to set environment variables PATH , CLASSPATH , JavaWom and what are their true values ​​like the importance of environmental variables ?

> JAVA_HOME is not used by Java Some third-party programs (for example, ApacheTomcat) expect one of these environment variables to be installed in JDK or JRE's installation directory. If you are not using software for which they need it, then you do not need to set up JWBHME and JRIOOM.

CLASSPATH is an environment variable that lists directories and / or jar files, which Java will search for when it searches for Java classes to load. Normally you do not have to set the CLASSPATH environment variable, instead of using this environment variable, you can use the -cp or -classpath option on the command line when using javac and java commands.

PATH An environment variable is used in the operating system (Windows, Mac OS X, Linux) where it will look for basic execution programs to run. You should add the bin subdirectory of your JDK installation directory to PATH, so that you can use javac and java commands and other jdk tools in the command prompt window.

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
