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:</p> <ul style="list-style-type: none; padding-left: 0;"> <li><img src="images/execute.gif" alt=""> Execute the example</li> <li><img src="images/code.gif" alt=""> Look at the source code for the example</li> <li><img src="images/return.gif" alt=""> Return to this screen</li> </ul> <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.</p> <table style="width: 85%;" > <tr> <td>Hello World</td> <td style="width: 30%;"><a href="servlet/HelloWorldExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/HelloWorldExample">Execute</a></td> <td style="width: 30%;"><a href="helloworld.html"><img SRC="images/code.gif" alt=""></a><a href="helloworld.html">Source</a></td> </tr> <tr> <td>Request Info</td> <td style="width: 30%;"><a href="servlet/RequestInfoExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/RequestInfoExample">Execute</a></td> <td style="width: 30%;"><a href="reqinfo.html"><img SRC="images/code.gif" alt=""></a><a href="reqinfo.html">Source</a></td> </tr> <tr> <td>Request Headers</td> <td style="width: 30%;"><a href="servlet/RequestHeaderExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/RequestHeaderExample">Execute</a></td> <td style="width: 30%;"><a href="reqheaders.html"><img SRC="images/code.gif" alt=""></a><a href="reqheaders.html">Source</a></td> </tr> <tr> <td>Request Parameters</td> <td style="width: 30%;"><a href="servlet/RequestParamExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/RequestParamExample">Execute</a></td> <td style="width: 30%;"><a href="reqparams.html"><img SRC="images/code.gif" alt=""></a><a href="reqparams.html">Source</a></td> </tr> <tr> <td>Cookies</td> <td style="width: 30%;"><a href="servlet/CookieExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/CookieExample">Execute</a></td> <td style="width: 30%;"><a href="cookies.html"><img SRC="images/code.gif" alt=""></a><a href="cookies.html">Source</a></td> </tr> <tr> <td>Sessions</td> <td style="width: 30%;"><a href="servlet/SessionExample"><img SRC="images/execute.gif" alt=""></a><a href="servlet/SessionExample">Execute</a></td> <td style="width: 30%;"><a href="sessions.html"><img SRC="images/code.gif" alt=""></a><a href="sessions.html">Source</a></td> </tr> </table> <p>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.
