Javac is not an internal or external command workaround (WIN7/WIN8)

Javac, why not?

Apache website now Windows under the whether JDK1.7 or JDK1.8 are not available in the zip version, only the EXE version, that is, installing more than two versions of the conflict will occur.

This is not the problem of the egg ache. The main is the environment variable configuration after java-version and Java is OK, but javac how can not?! Although this is a very simple question!

win8.1 under the JAVA environment, why the path under the%java_home% parse. But it can be replaced with an absolute path.

the ultimate solution: Replace the system environment variable with the Java_home from the user environment variable !
