In order to use Java from the command line, you also need to defineJAVA_HOMEorJRE_HOME, many Java-based programs and tools use these environment variables to access Java e.g. Maven, Tomcat, or Eclipse. Since Java is an optional package on the latest version of OS X, starting from OSX...
say if you have installed Java in the pathC:\Program Files\Java\jdk1.8.0_121on your computer, then yourJava_HomeisC:\Program Files\Java\jdk1.8.0_121. Basically, JAVA_Home is simply an example used by Java-based programs like Apache Tomcat and other app server tools to find where Java...
JRE stands for “Java Runtime Environment.” This package contains the tools and libraries needed to run a Java application. It’s a must-have to run any Java program on the system. Note that JDK comes bundled with JRE by default. So, you don’t have to install JRE separately if you...

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined(Tomcat安装报错) 一、Tomcat报错 二、问题原因 因为启动tomcat会调用tomcat安装文件中的startup.bat,而它调用了catalina.bat则调用了setclasspath.bat。因此需要在setclasspath.bat的开头手动声明环境变量。 三、解决方案: &nbs... ...
