extends javax.servlet.http.HttpServlet

The PhoneServlet example demonstrates processing data received from a form and reading data from a text file.

Build the Example

1. Open a new command shell.

2. Set up this development shell as described in Setting up Your Environment for Building and Running the Examples.

3. Build the servlet using ant:

     prompt> ant PhoneServlet

4. Start WebLogic Server with the examples configuration.

Configure the Server

Make sure that the examplesWebApp is deployed on your server.

Run the Example

Use a web browser to load the following URL:

http://localhost:7001/examplesWebApp/PhoneServletExample.html

Notes

This example makes entries to the WebLogic Server log file as the servlets executes. The location and name of your WebLogic Server log file is defined in the WebLogic Server Administration Console.

This example uses a text file called phonelist, located in your WebLogic Server installation, in the samples\examples\servlets directory. This file contains the phone number data. This is the file's contents:

#
# phone list
#
John   x5555
Paul   x9999
George x8888
Ringo  x5556
