Steps to use JavaStack in your computer:

Create a folder with permission to write (in your user folder or in C:\Temp). For example: C:\temp\Tomcat

Copy the following folders from C:\Programs\JavaStack\apache-tomcat-9.0.89 to C:\temp\Tomcat

Note: to reduce space, you can delete the folders docs and examples from webapps.

Define:

set CATALINA_HOME=C:\Programs\JavaStack\apache-tomcat-9.0.89
set CATALINA_BASE=C:\Users\name\Documents\Tomcat
set JAVA_HOME=C:\Programs\JavaStack\jdk1.8.0_131

Or you can create the file sj.bat in C:\temp\Tomcat:

To start Tomcat type:

startup

To test Tomcat, write in the browser

http://localhost:8082/

To stop Tomcat type:

shutdown

To try other apps, download CS repository from https://github.com/nicolasserrano/CS and copy some webapps to your webapps

To compile:

set CLASSPATH=%CLASSPATH%;.;%CATALINA_HOME%\lib\servlet-api.jar;

Summary of steps to create a servlet and start it in Tomcat:

Start Tomcat

  1. Follow the steps to use JavaStack in your computer

  2. Go to your Tomcat folder: >C:\temp\Tomcat

  3. Execute the sj.bat file: >sj

  4. Start the Tomcat server with the command: 
    startup

  5. Start the browser and write the address:
    http://localhost:8082

  6. Close the Tomcat server with the command: 
    shutdown

Create a Web page on the server

  1. Steps 1 to 3 of Start Tomcat (done)

  2. Create a folder called ‘firstWeb’ in the webapps folder of the Tomcat.

  3. Create the index.html file in the webapps\firstWeb folder with some html content

  4. Start the Tomcat server as in step 4 of Start Tomcat:

    startup

  5. Start the browser and write the address:
    http://localhost:8082/firstWeb

Create a Servlet

  1. Steps 1 to 3 of Start Tomcat (done)

  2. Create the folder structure of  ”Servlet1” application in the Tomcat installation
    • Create folder “Servlet1” in webapps folder of Tomcat
    • Create folder WEB-INF in webapps\Servlet1\ folder
    • Create folder classes in webapps\Servlet1\WEB-INF folder
    apache-tomcat-8.5.24
└── webapps
    └── Servlet1
        └── WEB-INF
            └── web.xml
            └── classes

  3. Create the  HelloWorld.java file in the webapps\Servlet1\WEB-INF\classes folder. HelloWorld.java

    import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet{
    public void doGet(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("Hello World");
    }
}
  4. Compile with the command javac: 
    javac HelloWorld.java

  5. Create the web.xml file in P:\apache-tomcat-8.5.24\webapps\Servlet1\WEB-INF folder:

    <?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>

<servlet>
  <servlet-name>primer</servlet-name>
  <servlet-class>HelloWorld</servlet-class>
</servlet>

<servlet-mapping>
  <servlet-name>primer</servlet-name>
  <url-pattern>/start</url-pattern>
</servlet-mapping>
</web-app>

  6. Start the Tomcat server as in step 4 of Start Tomcat:

    startup
  7. Start the browser and write the address:
    http://localhost:8082/Servlet1/start
