How to install Apache Servlet

This article only discusses how to install Apache Servlet on Windows NT 4.0.

The configuration in this article is as follows:
Windows NT 4.0
Jdk1_2_2-001-win.exe
Apache_1_3_12_win32.exe
ApacheModuleJServ. dll
Tomcat.zip (3.0)

I. Software Download
◆ JDK http://java.sun.com/products/jdk/1.2/
◆ Apache Server http://www.apache.org/dist/binaries/win32/apache_1_3_12_win32.exe
Http://jakarta.apache.org/builds/tomcat/release/v3.0/win32/ApacheModuleJServ.dll of Apache JServ
◆ Tomcat http://jakarta.apache.org/builds/tomcat/release/v3.0/tomcat.zip

Ii. Software Installation

1) JDK

Install jdk1_2_2-001-win.exe using the default configuration. The default installation directory of JDK is C: \ jdk1.2.2, and the default installation directory of JRE is C: \ Program Files \ mongooft \ JRE \ 1.2;

2. restart the computer;

3. Update the following environment variables: append the C: \ jdk1.2.2 \ bin directory to the PATH, and append C: \ jdk1.2.2 \ lib \ tools. jar; C: \ jdk1.2.2 \ lib \ dt. add jar to CLASSPATH. Update
Method: Choose Control Panel> system> environment> system variables;

4. Test the applet:
1) Open the command window;
2) switch to the C: \ jdk1.2.2 \ demo \ applets \ TicTacToe directory;
3) Run appletviewer example1.htm;
4) Everything is normal;

5. test application:
1) create a test. Java file under my D: \ HZQ \ java directory. The content is as follows:

 
 

  
  
Public class test
  
  
{
  
  
Public static void main (String arc []) {
  
  
System. out. println ("JDK has been installed successfully. Thank you! ")
  
  
}
  
  
}
 
 

2) Open the command window;
3) switch to the D: \ HZQ \ Java directory;
4) Run javac test. java for compilation;
5) run java test to run the program;
6) Everything is normal.

2) Apache Server

1. Double-click the apache_1_3_12_win32.exe file and use the default configuration for installation. The default installation directory is C: \ Program Files \ Apache Group \ Apache. I will use $ APACHE_ROOT instead of the installation destination;

2. Modify $ APACHE_ROOT \ conf \ httpd. conf:
1) PORT is used to set the Port number for running Apache Web Server. Because IIS is running here, IIS uses PORT 80, so I changed it to Port 8080, after entering http: // localhost: 8080/in the browser, you can access the Apache Web Server. When entering http: // localhost/, you can access IIS, in this way, both Web servers can be used. I use the $ APACHE_PORT ID;

2) DocumentRoot sets the document root directory. When you enter http: // localhost:/$ APACHE_PORT/in the browser, the server reads data from the document root directory, since all my programs are under D: \ HZQ, I set DocumentRoot to D:/HZQ;

3. After Apache is installed, add an Apache Web Server menu group to the "Start-> program" menu group and run the Install Apache as a service command, in this case, an Apache service is added to "start-> set-> Control Panel-> service". You can use it to start or stop the Apache service;

4. Open "start-> Settings-> Control Panel-> service", select the Apache service, and press "start" to start the Apache Servlet service;

5. Input http: // localhost:/$ APACHE_PORT/in the browser to view all the files under D: \ HZQ. This indicates that the Apache service has been installed successfully.

3) Apache JServ

1. Copy the ApacheModuleJServ. dll file to the $ APACHE_ROOT \ modules directory;

2. Modify $ APACHE_ROOT \ conf \ httpd. conf: Add LoadModule jserv_module modules/ApacheModuleJServ. dll to the file to start Apache JServ;

3. Restart the Apache service.

4) Tomcat

1. Decompress tomcat.zip to a directory with winzipet. I decompress it to C: \. It will automatically create a tomcat subdirectory, so that a directory C:/tomcat will be added to drive C, I use $ TOMCAT to identify;

2. Open the $ APACHE_ROOT \ conf \ httpd. conf file and add a similar sentence at the end of the file:
Include $ TOMCAT/etc/tomcat. conf
Here I will Include C:/tomcat/etc/tomcat. conf;

3. Modify the port number for running Tomcat. Note that Tomcat has an independent HTTP server.
The port number used. The port number 8081 is not occupied yet. I use $ TOMCAT_PORT to identify it and assign it to Tomcat:
1) Open $ TOMCAT/server. xml;
2) Modify ContextManager:

4. Double-click startup. bat in the $ TOMCAT directory to start Tomcat;

5. Enter http: // localhost:/$ TOMCAT_PORT/in the browser to view the Tomcat Version 3.0 page.
It indicates that Tomcat is successfully installed;

6. Enter http: // localhost:/$ APACHE_PORT/examples/servlets/in the browser.
Servlet Examples with Code indicates that Apache Servlet has succeeded;

7. Enter http: // localhost:/$ APACHE_PORT/examples/jsp/in the browser to view the jsp Samples.
This page indicates that Apache + jsp is successful.
