How to configure Java and Tomcat environment variables (WIN7)

1. Where to configure environment variables:

Select the "Computer" right button and select Properties to enter the following interface:

Click "Advanced System Settings":

Select environment variables and configure them in the system variables:

2. Configure Java Environment variables:

New system variable, variable name: Path, for example, Java installed in the C Disk program folder, then the value of the variable entered:

%java_home%\bin;%java_home%\lib\dt.jar;%java_home%\jre\bin;

New CLASSPATH variable name, variable value input: ".;"

New java_home variable name, variable value (Java installed directory) input:

C:\Program files\java\jdk1.7.0_10;

3. Configure Tomcat Environment variables:

New system variable, variable name: catalina_home, variable value (directory to which Tomcat is extracted), such as:

E:\apache-tomcat-7.0.54;

Add after system variable path:

%catalina_home%\lib;%catalina_home%\lib\servlet-api.jar;%catalina_home%\lib\jsp-api.jar;

Be careful not to delete the original and to separate the variables from each other.

4.Tomcat Administrator configuration, locate Tomcat-users.xml in the Conf folder under the installation directory and open edit:

<role rolename= "Manager-gui"/>

<role rolename= "Admin-gui"/>

<user roles= "Admin-gui" password= "admin888" username= "admin"/>

<user roles= "Manager-gui" password= "Tomcat" username= "Tomcat"/>

If the cmd window flashes when the Tomcat service is turned on, there may be an error in the Java environment variable configuration.
