|

<b><font face="Arial, Helvetica, sans-serif"><font size=+2>Servlet
|
||||
Examples with Code</font></font></b>
|
||||
<p>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.
|
||||
<p>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 <i>README</i> file provide with this Tomcat release regarding
|
||||
how to configure and start the provided web server.
|
||||
<p>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.
|
||||
<p>To navigate your way through the examples, the following icons will
|
||||
help:
|
||||
<br>
|
||||
<table BORDER=0 CELLSPACING=5 WIDTH="85%" >
|
||||
<tr VALIGN=TOP>
|
||||
<td WIDTH="30"><img SRC="images/execute.gif" ></td>

|

|

<p>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.
