MyEclipse+Jboss+HSQL开发Servlet服务器
一.工具软件名称：
MyEclipse 8.0 +jboss-4.0.5.G
二.准备工作：
解压jboss，然后设置系统Path,%JBOSS_HOME%/bin;
三.在MyEclipse8里配置JBOSS服务器
在MyEclipse8下的Window-->Preferences下的Servers找到JBoss下的JBoss4.x
点OK后
这个小三角下就有一个JBOSS4.X，点Start运行服务器。
四.使用Hypersonic 数据库创建一个表格的具体步骤：
步骤一：测试JBoss服务器是否正常运行，在IE浏览器中输入网址：http://127.0.0.1:8080/jmx-console/
步骤二：在该网页中查找一个叫做“jboss”子标题，其下有个超级链接，该超级链接文字是
“database=localDB,service=Hypersonic”
步骤三：在该页面中有一个叫做“startDatabaseManager”的MBean 操作，在它的右边有个“Invoke”
步骤四：点击“Invoke”按钮则会弹出一个名为“HSQL Database Manager”的数据库管理程序。左边列举了目前数据库中已经存在的表格和数据库的名称，右边是一个用于输入SQL语句的文本框和一个显示结果的文本框。
步骤五：在“HSQL Database Manager”的数据库管理程序中创建两个表格（用于“联网心理测试”），
其中表格“STOREANSWER”包括3个字段：用户，ID，用户姓名和测试答案，这个表格存储客户端的一些基本信息和测试答案。
表格“IQQUESTION” 包括3个字段：问题序号，问题内容，问题的标题答案，这个表格负责提供测试的题目和标准答案，
创建表格的代码如下：
CREATE TABLE STOREANSWER (USERID VARCHAR(6) NOT NULL PRIMARY KEY,USERNAME VARCHAR(15),ANSWER VARCHAR(30))
CREATE TABLE IQQUESTION (ANSEWRID VARCHAR(6) NOT NULL PRIMARY KEY,QUESTION VARCHAR(500),ANSWER VARCHAR(2))
在工具栏单击“Execute SQL Statement”
步骤六：在表格“IQQUESTION”中填入一些测试数据，代码如下：
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q1','Question1','A')
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q2','Question2','B')
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q3','Question3','C')
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q4','Question4','D')
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q5','Question5','A')
INSERT INTO IQQUESTION (ANSWERID , QUESTION , ANSWER) VALUES ('Q6','Question6','B')
在工具栏单击“Execute SQL Statement”
步骤七：在右边输入查询语句，SELECT * FROM IQQUESTION,在工具栏单击“Execute SQL Statement”
五：编写测试程序Servlet
步骤一：在MyEclipse8下创建HttpServlet，file—>new—>Web Project 建个工程名为ServletTest，
步骤二：在此工程下新建一个Servlet，命名为NetWorkTest ，在file—>new—>MyEclipse—>web—>Servlet
代码如下：
package com.test;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import javax.naming.InitialContext;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.DataSource;
public class NetWorkTest extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
// 连接池名称
protected static final String DBName = "java:DefaultDS";
private DataSource dataSource;
private String question;
public void init(ServletConfig config) throws ServletException {
try {
// 初始化连接池
InitialContext ic = new InitialContext();
dataSource = (DataSource) ic.lookup(DBName);
} catch (Exception e) {
e.printStackTrace();
throw new ServletException("init error");
}
}
/**
* Constructor of the object.
*/
public NetWorkTest() {
super();
}
/**
* Destruction of the servlet.
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
/**
* The doGet method of the servlet.
*
* This method is called when a form has its tag value method equals to get.
*
* @param request
* the request send by the client to the server
* @param response
* the response send by the server to the client
* @throws ServletException
* if an error occurred
* @throws IOException
* if an error occurred
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String userid = null;
Connection c;
try {
c = dataSource.getConnection();
// 执行查询语句
PreparedStatement ps = c.prepareStatement("SELECT *"
+ " FROM IQQUESTION");
ResultSet rs = ps.executeQuery();
PrintWriter out = response.getWriter();
while (rs.next()) {
// 获得表格第一个字段的数据
question = rs.getString(2);
response.setContentType("text/plain");
// 显示到屏幕上
out.print(this.getServletInfo() + "/n");
out.print("QUESTION:" + question + "/n");
out.print("
");
}
// out.flush();
out.close();
rs.close();
ps.close();
c.close();
} catch (Exception e) {
e.printStackTrace();
}
// response.setContentType("text/html");
// PrintWriter out = response.getWriter();
// out
// .println(""-//W3C//DTD HTML 4.01 Transitional//EN/">");
// out.println("");
// out.println(" A Servlet");
// out.println(" ");
// out.print(" This is ");
// out.print(this.getClass());
// out.println(", using the GET method");
// out.println(" ");
// out.println("");
}
/**
* The doPost method of the servlet.
*
* This method is called when a form has its tag value method equals to
* post.
*
* @param request
* the request send by the client to the server
* @param response
* the response send by the server to the client
* @throws ServletException
* if an error occurred
* @throws IOException
* if an error occurred
*/
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
// response.setContentType("text/html");
// PrintWriter out = response.getWriter();
// out
// .println(""-//W3C//DTD HTML 4.01 Transitional//EN/">");
// out.println("");
// out.println(" A Servlet");
// out.println(" ");
// out.print(" This is ");
// out.print(this.getClass());
// out.println(", using the POST method");
// out.println(" ");
// out.println("");
// out.flush();
// out.close();
}
}
步骤三：在web.xml中输入发布Servlet必须信息。
代码如下：
1: servlet>
2: description>This is the description of my J2EE componentdescription>
3: display-name>This is the display name of my J2EE componentdisplay-name>
4: servlet-name>NetWorkTestservlet-name>
5: servlet-class>com.test.NetWorkTestservlet-class>
6: servlet>
7:
8: servlet-mapping>
9: servlet-name>NetWorkTestservlet-name>
10: url-pattern>/NetWorkTesturl-pattern>
11: servlet-mapping>
注意：第5，10行一定要和上面的一样。com.test是包名
步骤四：发布Servlet,点MyEclipse里
发布按钮，
在这个窗口里选要发布的项目名，ServletTest，在点add，找到jboss服务器，
一路OK后。就发布完了。
步骤五：启动JBOSS
jboss –>start
六：在IE浏览器上访问Servlet
在IE浏览器上输入http://127.0.0.1:8080/ServletTest/NetWorkTest
七：这时你的服务器就配置完了。
