Editor to share with you how to install and activate JSP myeclipse, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. JAVA_HOME,PATH,CLASSPATH

1. JAVA_HOME environment variable. It points to the directory where jdk is installed. Setting it up has two advantages: first, software such as Eclipse/NetBeans/Tomcat searches the JAVA_HOME variable to find and use the installed jdk. Another benefit is that when we need to change to another jdk, we can just change the value of JAVA_HOME.

2.PATH environment variable. PATH tells the operating system the path where the executable is located. When the operating system finds an executable file, it first looks for it under the current path, and if it cannot find it, it will find it under the path specified by PATH. The bin directory under the jdk installation directory contains frequently used executable files such as javac/java/javadoc. Point PATH to the bin directory under the jdk installation directory and you can execute javac/java and other tools in any directory.

3. CLASSPATH environment variable. It tells the java virtual machine (jvm) where to put the * .class files to use. If you just learn Java, the default class is enough for us to use, so it doesn't matter if you don't set it. We usually set the value of CLASSPATH to the lib directory under the jdk installation directory.

At this point, we will know why Note1 should configure jdk like that! Let's install and activate myeclipse.

Second, install and activate myeclipse

MyEclipse is an enterprise integrated development environment developed on the basis of Eclipse and its own plug-ins, which is mainly used for the development of Java, JavaEE and mobile applications, but it is a fee-based software compared to eclipse,myeclipse.
