Enterprise Java for Linux HOWTO 

Setting up Your Environment 

You will need to stop, set your Java environment variables, and restart Apache to register Apache JServ. 

To stop Apache, type: 

cd /etc/rc.d/init.d

./httpd stop

Note: The httpd script used at boot time may be in a different location on other Linux distributions 

To set you Java environment, see the How to Install the JDK section of this document, specifically for the

JDK you intend to use.  You need to set several properties in the jserv.properties file installed in

/etc/httpd/conf/jserv. Specifically, look for: 

wrapper.bin - to reference the JDK you installed 

wrapper.classpath - to minimally include /usr/lib/apache/ApacheJServ.jar and

/home/httpd/classes/servlet-2.0.jar 

bindaddress=localhost 

port=8007 

To restart Apache, type: 

cd /etc/rc.d/init.d

./httpd start

Confirming Your Installation 

To confirm that the Apache JServ is installed and running on your computer, open your web browser, and

enter the URL: "http://127.0.0.1/servlet/IsItWorking" substituting the correct IP address if you are browsing

from another machine. 

You should see a web page to the effect of "Yes, It s Working!". Contratulations, you have installed, set up an

environment for, and tested the Apache JServ for Linux. 

For more assistance, I suggest you look into the Apache JServ website at 

http://java.apache.org/jserv/index.html

. 

Now, to compile and run your own servlet.  Enter the following Java servlet program. 

import java.io.*;  

import javax.servlet.*; 

import javax.servlet.http.*; 

public class HelloWorldServlet extends HttpServlet { 

  public void service (HttpServletRequest request, 

    HttpServletResponse response) throws ServletException, IOException { 

  } 

}
