Servlet Examples with Code
This is a collection of examples which demonstrate some of the more frequently used parts of the Servlet API. Familiarity with the Java(tm) Programming Language is assumed.
These examples will only work when viewed via an http URL. They will not work if you are viewing these pages via a "file://..." URL. Please refer to the README file provide with this Tomcat release regarding how to configure and start the provided web server.
Wherever you see a form, enter some data and see how the servlet reacts. When playing with the Cookie and Session Examples, jump back to the Headers Example to see exactly what your browser is sending the server.
To navigate your way through the examples, the following icons will
|Execute the example|
|Look at the source code for the example|
|Return to this screen|
Tip: To see the cookie interactions with your browser, try turning on
the "notify when setting a cookie" option in your browser preferences.
This will let you see when a session is created and give some feedback
when looking at the cookie demo.
Note: The source code for these examples does not contain all of the source code that is actually in the example, only the important sections of code. Code not important to understand the example has been removed for clarity.
Using our MysqlExample for an example, you would recompile this using the command:
From your home directory (/pub/users/xxxx/www) :
javac -classpath /usr/local/etc/tomcat/common/lib/servlet.jar MysqlExample.java
This will produce a file named MysqlExample.class.
From the web, you can then access this using the url:
The /servlet in the URL uses Tomcat's built-in Invoker servlet to launch the class file from the WEB-INF/classes/ directory.
