Tomcat configuration environment variables

1. Install JDK and Tomcat
1. Install JDK: directly run the jdk-7-windows-i586.exe executable program, which can be installed by default.
Note: The path can be other drive letters, and it is not recommended that the path contain Chinese names and special symbols.
2. Install Tomcat: directly decompress the downloaded file "apache-tomcat-7.0.33-windows-x86.zip" to the C drive. It is recommended to modify the installation path to: c:\tomcat.
Note: If you download an executable file, double-click to run, and the default installation can be done.

2. Configure JDK environment variables (see how to configure environment variables in the steps)
1. New variable name: JAVA_HOME, variable value: C:\Program Files\Java\jdk1.7.0
2. Open PATH and add variable value: %JAVA_HOME%\ bin;%JAVA_HOME%\jre\bin
3, new variable name: CLASSPATH, variable value: .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jarRemarks
:
1, . indicates the current path, %JAVA_HOME% refers to the JAVA_HOME specified earlier;
2, JAVA_HOME indicates the JDK installation path, which includes lib, bin, jre and other folders, and the operation of tomcat, eclipse, etc. needs to rely on this variable.
3, PATH enables the system to recognize java commands in any path.
4. CLASSPATH is the path of the java loaded class (class or lib), and the java command can only be recognized if the class is in the classpath.

3. Test JDK
