JBuilder2005 + JBoss 4.0 開發 Session Bean 實戰（四）：測試與部署驗證

JBuilder2005 + JBoss 4.0 開發 Session Bean 實戰（四）：測試與部署驗證

系列最終篇：建立測試專案、編寫客戶端 Servlet、打包 EAR 部署至 JBoss、瀏覽器驗證 Session Bean 呼叫結果。

1. 建立測試包與類別

在專案 com.inspiresky.trader 下新建 user 子包，加入兩個類別：

UserInfo.java — 封裝 EJB 查找與呼叫

package com.inspiresky.trader.user;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import trader.UserInfoLocalHome;
import trader.UserInfoLocal;
import javax.ejb.CreateException;
import java.rmi.RemoteException;
import java.util.*;
import java.util.Date;

public class UserInfo {
    public HashMap getUserInfo() {
        HashMap map = new HashMap();
        try {
            UserInfoLocal local = (UserInfoLocal) findEjb();
            map = local.showUserInfo();
        } catch (CreateException | RemoteException | NamingException ex) {
            System.out.println("Error: " + ex.getMessage());
        }
        return map;
    }

    private Object findEjb() throws NamingException, RemoteException, CreateException {
        Context ctx = new InitialContext();
        Object obj = ctx.lookup("UserInfoLocal"); // JNDI 名稱
        UserInfoLocalHome home = (UserInfoLocalHome) PortableRemoteObject.narrow(obj, UserInfoLocalHome.class);
        return home.create("Jak", "12", new Date().toString());
    }
}

Test.java — HttpServlet 客戶端

package com.inspiresky.trader.user;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class Test extends HttpServlet {
    private static final String CONTENT_TYPE = "text/html; charset=GBK";
    private HashMap map;

    public void init() throws ServletException {
        UserInfo user = new UserInfo();
        map = user.getUserInfo();
    }

    public void doGet(HttpServletRequest req, HttpServletResponse res)
            throws ServletException, IOException {
        res.setContentType(CONTENT_TYPE);
        PrintWriter out = res.getWriter();
        out.println("");
        out.println(map.toString()); // 輸出 {userName=Jak, userAge=12, loginTime=...}
        out.println("");
        out.close();
    }
    public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { doGet(req, res); }
    // doPut/doDelete/destroy 略
}

2. 修改 web.xml 註冊 Servlet

<servlet>
  <servlet-name>test</servlet-name>
  <servlet-class>com.inspiresky.trader.user.Test</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>test</servlet-name>
  <url-pattern>/test</url-pattern>
</servlet-mapping>

完整 web.xml 含 log4j-init Servlet（見第三篇）。

3. 建立 Enterprise Application (EAR) 部署包

1. 選單 New → Enterprise → Application Module (EAR)，名稱 ETrader。
2. 勾選包含 Trader (EJB Module) 與 WebTrader (WAR Module)。
3. Finish。

{userName=Jak, loginTime=Wed Mar 30 11:26:18 CST 2005, userAge=12}
