1. Use the editor you are most familiar with (it is recommended to use the Java IDE with syntax check), the file name is Test.java, the file content is as follows:

Package test;

Import java.io.ioException;

Import java.io.printwriter;

Import javax.servlet.servletException;

Import javax.servlet.http.httpservlet;

Import javax.servlet.http.httpservletRequest;

Import javax.servlet.http.httpservletResponse;

Public class test extends httpservlet {

Protected Void Doget (HttpservletRequest Request, HttpservletResponse Response)

Throws servletexception, ioException {

PrintWriter out = response.getwriter ();

Out.println ("

this is a servlet test. ");

Out.flush ();

}

}

2. Compile Test.java Under C: / Test, compile: C: / test> Javac test.java then generate a compiled servlet file under C: / Test: Test.class

3. Cut the structure Test / Test.class to% catalina_home% / WebApps / myApp / web-inf / class, that is, cut that Test directory to the class content, if the class content does not exist, will create a new one. Now WebApps / MyApp / Web-INF / CLASSES has Test / Test.class file directory structure

4. Modify WebAPPS / MyApp / Web-INF / Web.xml, add servlet and servlet-maping edited Web.xml as follows: MY Web Application a application for test. test test A Test servlet test.test test / TEST This paragraph declares that the servlet you want to call, and servlet-mapping is the declared servlet "mapping" to address / Test 5. Ok, start Tomcat, start the browser, enter http: // localhost: 8080 / myapp / test If you see the output this is a servlet test. The written servlet is successful.
