1. Download to the Sun Homepage Download the JDK installation version, assuming that the JDK is installed in C: /J2SDK1.4.2_03/, then set the environment variable java_home as C: /J2SDK1.4.2_03/, and then add C: / J2SDK1 in the environment Path variable. 4.2_03 / bin; add Tools.jar and Dt.jar in the ClassPath environment variable, if there is no ClassPath environment variable, create it. 2. Download the Tomcat installation version, assuming Tomcat is installed in c: /tomcat4.1; then set the environment variable Catalina_home is C: /Tomcat4.1; simultaneously add C: /Tomcat4.1/bin to the PATH environment variable. When you install Tomcat, you will be prompted to enter the password of Admin. This password is used to configure Tomcat. 3. Execute Catalina_Home / Bin / Startup.bat, launch Tomcat. Open the IE browser, type http: // localhost: 8080 / (guarantee port not to conflict with other server). "Tomcat Administration" appears on the left side of the page, "Tomcat Manager" two connections. 4. Create a web-inflicity under the C: / Establishing the Webroot directory, establish a web-infer in WebRoot, and establish a web.xml file in Web-INF. Edit Web.xml file, enter:
myfirstwebsite first Web then saved. 5. Click on "Tomcat Manager" to enter the username password (admin, admin) entered when installing. This is a graphical interface that manages Tomcat. 6. Open Catalina_Home / conf / server.xml, find , then add , Save, restart Tomcat, build an index.html under C: / Webroot, content yourself, then open IE, knock: http: // localhost: 8080 / Webroot / INDEX.html, you can browse The HTML file you just created just now. By this step, it basically established a separate site.
The following describes how to use JSP and servlets. 1. We build helloworld.jsp under C: / Webroot, enter the following:
hello! </ Title> <meta name = "generator" content = "editplus"> <meta name = "Author" content = "> <meta name =" keywords "content ="> <meta name = "description" content = "> </ head> <body> <% out.println (" Hello World! " );%> </ Body> </ html> Save, then open the browser, knock: http: // localhost: 8080 / Webroot / HelloWorld.jsp, you can view the contents of JSP output.</p>
<p>2. We created a servlet, named myServlet1.java, put under the C: / Webroot / SRC, the input content is as follows: import javax.servlet. *; Import javax.servlet.http. *; Import java.io. *; Import java.util. *;</p>
<p>/ ** * <p> Title: </ p> * <p> Description: </ p> * <p> Copyright: Copyright (c) 2003 </ p> * <p> Company: </ p> * @ Author not attributable * @version 1.0 * /</p>
<p>public class MyServlet1 extends HttpServlet {private static final String CONTENT_TYPE = "text / html; charset = GBK"; // Initialize global variables public void init () throws ServletException {} // Process the HTTP Get request public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {response.setContentType (CONTENT_TYPE); PrintWriter out = response.getWriter (); out.println ( "<html>"); out.println ( "<head> <title> MyServlet1 </ title > </ head> "); out.println (" <body bgcolor = / "# fffffff /"> "); out.println (" <p> the servlet Has Received A Request.getMethod () ". This is the reply </ p> "); out.println (". </ body> </ html> ");} // Process the HTTP Post request public void doPost (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {Doget (Request, Response);} // clean up resources public void design () {}} 3. Open web.xml (where you know it), editing as follows: <? XML Version = "1.0" encoding = " ISO-8859-1 "?></p>
<p><! Doctype web-app public "- // sun microsystems, incaps//dtd web application 2.3 // en" "http://java.sun.com/dtd/web-app_2_3.dtd"></p>
<p><web-app> <display-name> MyfirstWebsite </ display-name> <description> first Web </ description></p>
<p><servlet> <servlet-name> MyServlet1 </ servlet-name> <servlet-class> myservlet1 </ servlet-class> </ servlet> <servlet-maping> <servlet-name> MyServlet1 </ servlet-name> <URL -pattern> / myServlet1 </ url-pattern> </ servlet-mapping> </ web-app> saves.</p>
<p>4. Compile Servlet: Create a lib directory in C: / Webroot / Web-INF / C: C: / Tomcat 4.1 / Common / lib / servlet.jar to the lib directory. Create a classes directory in C: / Webroot / Web-INF /. The Complier.bat content is built in C: / Webroot / below: javac -classpath ./web-inf/lib/servlet.jar; ./src/*.java -d ./web-inf/classespause runs company.bat Re-re- Start Tomcat, open the browser to knock http: // localhost: 8080 / Webroot / MyServlet1, execute, if it is the reply. "Indicates that the execution is successful.</p></div><div class="text-center mt-3 text-grey">
