2. Run the installation package to select the installation path

To install the JDK, choose the directory simply by the default installation directory (for example: D:\java),

Install the JRE and install the JDK directory,

After installation: D:\java\jdk,d:\java\jre

3. Configure Environment variables

System Variable →path→ edit: Enter%java_home%\bin;%java_home%\jre\bin at the end of the variable value ( Note If the value of the variable has no semicolon at the end, enter the semicolon first )

System variables → new →classpath: Fill in .; %java_home%\lib;%java_home%\lib\tools.jar(Note that there is a point in the front)

4, check whether the installation is successful

In the DOS command window, type the following command:

Java-version

Ii. installation of Tomcat

1. Decompression version

Unzip the package directly to the target path (for example: D:\JavaTool\apache-tomcat-8.0.21-windows-x64\apache-tomcat-8.0.21),

You can start Tomcat by double-clicking the startup.bat file in the bin directory

Enter http://localhost:8080/in the browser, if the Welcome page appears, the installation is successful.

2. Installation version

Run the installation package to select the destination path.

Third, Eclipse installation

1. Download the Eclipse package

2. Extract to target path (e.g. D:\JavaTool\eclipse-jee-luna-SR1-win32-x86_64)

Iv. installation of the Tomcat plugin in eclipse

1, download the plugin. Address: http://www.eclipsetotale.com/tomcatPlugin.html

2, unzip the download package, put it into Eclipse's plugins directory to restart Eclipse, the Tomcat plugin was successfully installed!
