However, there are many ways to have many configurations on the network. Most of them are troublesome, such as using MOD_JK. And those methods are not applicable to the latest distribution software here (I tried, you can try, pay attention to the Windows series, if the Tomcat4.0 is combined, apache1.3.23 is the most stable version, Apache1 .3.6 or apache2.0 will have problems).

Java 2 (JDK1.4.0-B92) is the << Latest version >> Java compiler released by Sun. The download address is: www.sun.com/j2se/1.4/

Tomcat-4.0 is a web server that supports the latest JSP for Apache organizations. The download address is: http://jakarta.apache.org/builds/jakarta-tomcat/release/apache1.3.23-win32 is the Apache organization released the most stable web server that supports Window 98 / NT / 2000. The download address is: http://www.apache.org/dist/httpd/

WebApp-Module-1.0 is a support interface that Apache and Tomcat is better than Apache organization. The download address is: http://www.apache.org/dist/httpd/

Win2000 (Family) Server does not need to be explained. / / Oh, if you don't know, you don't look down.

Configuration method:

First, install Win2000, if you use it, this step can be.

Second, A: Download Java2 (JDK1.4.0), the downloaded file name is: J2SDK-1_4_0-win.exe. Double-click to run, press the default to install it to the C: /J2SDK1.4.0 directory. JRE will be automatically installed to C: / Program Files / Java / J2RE1.4.0, JRE is the necessary support environment that runs Java programs.

B: After installation, you need to set the path: The method is as follows: Click "My Computer" right-Property-Advanced - environment variable, the new "Java_Home" value in "System Variable" is: C: / J2SDK1. 4.0

Note: The row of the front belt // below is to choose one of the rows of //, that is, both only need to do one time. // New: ClassPath value is: //c:/j2sdk1.4.0 /LIB/dt.jar;c :/j2sdk1.4.0/lib/tools.jar;c:/j2sdk1.4.0/lib/htmlconverter.jar;c:/program files / apache tomcat 4.0 / common / lib / servlet.jar / / Note that you should write, use ";", " ; C: / program files / apache tomcat 4.0 / common / lib // Note To write, use ";" separation; // New: _Runjava, value is: c: /j2sdk1.4.0/bin/java // New: _Runjavaw, value: c: /j2sdk1.4.0/bin/javaw // New: _runjdb, value is: c: /j2sdk1.4.0/bin/jdb // The above variables built in compilation JSP and SERVLETS

Then, double-click the PATH variable here, add:; C: /J2SDK1.4.0/bin so that you can compile the Java file elsewhere.

C: Test JDK installation success: Built a Myjava directory in C: /J2SDK1.4.0, then copy C: /J2SDK1.4.0/Demo /Applets/clock to the case1.html to the Myjava directory, then Execute:> Javac Clock.java> AppletViewer Example1.html You can see a moving clock that pops up, indicating that the test applet is successful. Then Test the Java Application Use the following program to note the Note Test.java file, pay attention to the extension .java. Public class test {public static void main (string args []) {system.out.print ("Hello World, JDK SETUP SUCCESSFUL! / N");}} Put this Test.java file in the Myjava directory, then execute :> Javac Test.java> Java Test can see the "Hello World, JDK SETUP SUCCESSFUL!" Text, indicating that JDK is installed.

Third, A: Install Tomcat-4.0, downloaded the file name is: jakarta-tomcat-4.0.3.exe, run it directly and press it by its default directory to C: / Program Files / Apache Tomcat 4.0 below. B: Configure Tomcat Path: 1: Click "My Computer" right-Property - Advanced - environment variable, in "System Variable" New "Catalina_Home" value: c: / program files / apache tomcat 4.0 // 2 : Find the C: / Program files / apache tomcat 4.0 / bin / setclasspath.bat file, change all of these% basedir% // to% catalina_home% // and find the set classpath, change to: // set Classpath =% java_home% / lib / Tools.jar;% java_home% / lib / dt.jar;% java_home% / lib / htmlconverter.jar;% catalina_home% / common / lib / servlet.jar // setClassPath.bat file is Tomcat provides a batch file for setting library files, which can test whether your running environment // ClassPath is correct. Its content should be revised as follows: if not "% JAVA_HOME%" == "" goto gotJavaHomeecho The JAVA_HOME environment variable is not definedecho This environment variable is needed to run this programgoto end: gotJavaHomeif exist "% JAVA_HOME% / bin / java .exe "goto okJavaHomeecho The JAVA_HOME environment variable is not defined correctlyecho This environment variable is needed to run this programgoto end: okJavaHomeif not"% CATALINA_HOME% "==" "goto gotBasedirecho The CATALINA_HOME environment variable is not definedecho This environment variable is needed to run this programgoto end: gotBasedirif exist "% CATALINA_HOME% / bin / setclasspath.bat" goto okBasedirecho The CATALINA_HOME environment variable is not defined correctlyecho This environment variable is needed to run this programgoto end: okBasedirrem Set the default Java options for all scriptsset JAVA_OPTS = Rem set the default -djava.endorsed.dirs argumentset java_endorsed_dirs =% catalina_home% / bin;% catalina_home% / common / lib

rem Set standard CLASSPATHrem Note that there are no quotes as we do not want to introduce randomrem quotes into the CLASSPATHset CLASSPATH =% JAVA_HOME% / lib / tools.jar;% JAVA_HOME% / lib / dt.jar;% JAVA_HOME% / lib / htmlconverter.jar;% CATALINA_HOME% / common / lib / servlet.jarrem Set standard command for invoking Java.rem Note that NT requires a window name argument when using start.rem Also note the quoting as JAVA_HOME may contain spaces.set _RUNJAVA = " % Java_home% / bin / java "set _Runjavaw ="% java_home% / bin / javaw "set _runjdb =" java_home% / bin / jdb ": End // If you have a little understanding of the batch file, you can easily see Understand the code above.

Note: The top of the top with //, the row with the top of the top, select one, that is, the two can only be done once. C: Configure Tomcat configuration file, in C: / Program Files / Apache In Tomcat 4.0 / conf / server.xml, you are not configured, if you want to configure it, you can match it below. D: Test Tomcat Installation Success: Open IE, type in the address bar: http: // localhost: 8080 You can see Tomcat's page. Or enter http://xxx.xxx.xx.xxx:8080 where xxx.xxx.xx.xxx is your Win2000's IP address. E: How to configure Tomcat to run your own JSP file and Java servlet, will explain the following: 1: Configure the Tomcat's server.xml file to support your JSP file. Use Notepad to open the server.xml file below Conf, find it: ............! - Tomcat root context -> ->

........... A few lines. Then add the following lines in the "DocBase =" root "debug =" 0 "/> ->" above: This is a directory MYJSP that puts its own JSP file in the root directory below the WebApps directory (Tomcat's default page directory). Of course, before doing the above steps, you must first build an empty myjsp directory in the root directory. If you want to add a few JSP directories, you can add it to the same aspect. 2: Test your own JSP files in the Myjsp directory, build a file name: helloWorld.jsp, use Notepad Editing to make its content as:

<% = msg%> saved file, boots Tomcat server, then in the browser Enter http: //xx.xxx.xxx.xx: 8080 / myjsp / helloWorld.jsp can see the output. Or enter http: //xxx.xxx.xxx.xx: 8080 / myJSP / you can browse the directory, then click the file. Note xxx.xxx.xxx.xx is your IP address, or LocalHost. Note: The file name is the case.

3: Sets the Tomcat to run your own servlet to build a class content in the web-inf directory below the root, then use Notepad to open the Web.xml of the web-inf directory in the ROOT in the Increase content between , make it a web.xml content as shown below: Hello this servlet plays the" Hello World Example "role. Just A Hello World Program! Hello 5 Hello *. do 30 Web.xml is the easiest declaration for servlet, which declares a servlet called Hello, use it We test. hello *. Do The declaration is available in servletname.do in the browser to browse this servlet with localhost: 8080 / hello.do. The * .do here is arbitrary, or may be set to * .pl and so on.

You can also use the hello * to use the servlet name to browse the servlet Here, Localhost: 8080 / Hello can also use Hello / servlet / * For replacement, this time is to use the path name and servlet name to browse the servlet, which is localhost: 8080 / servlet / hello 4: Test your own servlet, built a named hello.java file, input it follows: import java.io *; import javax.servlet *; import javax.servlet.http *; public class hello extends HttpServlet {public void init (ServletConfig config) throws ServletException {super.... init (config);} public void destroy () {super.destroy ();} public void service (HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {resp.setContentType ( "text / html"); PrintWriter out = new PrintWriter (Resp.getOutputStream ()); out.println (""); out.println ("
