实战JBuilder7+WebLogic7（四）续 JMS+Message-Driven Bean
刘晓巍: [email protected]
第一次写文章，希望大家多多捧场，本文完全根据我的个人经验所写，如有错误，恳请大家指正！JBuilder7+WebLogic7 的配置
假设Jbuilder7和WebLogic7安装完毕，操作系统为:windows2000 server(SP2),数据库为： SQLServer2000(SP2)。
JBuilder7的配置：1. 修改环境变量TEMP和TMP 为不带空格的目录如：E:\winnt\temp2. 启动Jbuilder7，选择：Tools->Configure Servers3. 选中左侧的Weblogic Application Server 6.x+，选中右边的Enable Server4. 将General->Home Directory设为WebLogic7的Home Directory如：E:/bea/weblogic700/server，正常的话Jbuilder7将自动为你添好其他的项。5. 将Custom->JDK Installation Directory设为 JDK的安装目录，如：E:/bea/jdk131_026. 将Custom->BEA Home Directory设为WebLogic7的Home Director,如：E:/bea7. 将Custom->Domain Directory设为你的域目录，如：E:/bea/user_projects/mydomain8. 添好User name, Password ,Domain name, Server name后，单击OK退出。9. 选择：Tools->Enterprise Setup，单击CORBA页上的New, 按下表填写相应信息：Name for this configuration = WelLogic 7.0Path for ORB Tools = E:/bea/weblogic700/serverLibrary for Projects = WebLogic 6.x+ DeployIDL compiler command = idlj.exeCommnad option for output directory = E:\CORBAOutput(任意目录，不要有空格)单击OK退出。10．选择Project->Default Project properties在Path页的Required libraries中将会看到WebLogic 6.x+ Client和WebLogic 6.x+ Deploy两项，如果没有，请检查以上步骤是否正确。11．选择Server页，单击Single services for all service in project在下拉列表中选择WebLogic Application Server 6.x+，但击OK退出，配置完毕。
WebLogic7的配置：1．启动WebLogic72．打开IE6，在地址栏中输入：<http://localhost:7001/console>3．输入用户名和密码4．在左边的目录树中选中Services->JDBC->Connection Pools，单击右侧的Configure a new JDBC Connection Pool.，输入以下信息：Configuration->General页：Name = SQL Server Connection PoolURL = jdbc:weblogic:mssqlserver4:northwind@localhostDriver classname = weblogic.jdbc.mssqlserver4.DriverProperties : user = saPassword = “” <- sa的密码单击Create建立连接池。Targets->Server页：将myserver(服务器名称)移至右侧的列表中，但击单击Apply5．在左边的目录树中选中Services->JDBC->Data Sources（或者TXData Sources），单击右侧的Configure a new JDBC Connection Pool.，输入以下信息：Configuration->General页：Name ＝ SQLServer Tx Data SourceJNDI Name ＝ SQLServerPool Name = SQL Server Connection Pool选中Emulate Two-Phase Commit for non-XA Driver和Row Prefetch Enabled单击Create建立数据源。Targets->Server页：将myserver(服务器名称)移至右侧的列表中，但击单击Apply，配置完毕。实战1：连接SQLServer2000
1．打开JBuilder7选择File－>New project在Name栏中输入SQLServerDemo，Directory栏中输入存放路径（不要有空格），其他不变，单击Finish。2．选择File－>New，选择General->Application，单击OK。第一步，第二步和第三步都不用更改，直接Finish即可。3．回到JBuilder7的集成开发环境中，单击右侧的Designer页设计窗体，在窗体中放入一个JscrollPane 和JtextArea 及二个按钮，双击第一个按钮输入以下代码：try{Class.forName("weblogic.jdbc.mssqlserver4.Driver");Connection con = DriverManager.getConnection("jdbc:weblogic:mssqlserver4:northwind@localhost","sa","");//此处根据你的SQLServer帐户而定。Statement st = con.createStatement();ResultSet res = st.executeQuery("select * from employees");String line = "";while (res.next())line = line + res.getString("title")+"\n";jTextArea1.setText(line);con.close();}catch (Exception ex){jTextArea1.setText("error : "+ex.getMessage());}双击第二个按钮输入以下代码Hashtable ht = new Hashtable();ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");ht.put(Context.PROVIDER_URL,"t3://localhost:7001");
try{Context ctx = new InitialContext(ht);DataSource ds = (DataSource)ctx.lookup("SQLServer");Connection con = ds.getConnection("system","12345678");//此处是WebLogic7的域用户和密码Statement st = con.createStatement();ResultSet res = st.executeQuery("select * from employees");String line = "";while (res.next())line = line + res.getString("notes")+"\n";jTextArea1.setText(line);con.close();}catch (Exception ex){jTextArea1.setText("error : "+ex.getMessage());}4．别忘了，在程序开始处加入以下代码：import java.sql.*;import java.util.*;import javax.sql.*;import javax.naming.*;运行WebLogic7，运行程序单击第一个按钮使用JDBC直接连接SQLServer并获取数据，单击第二个按钮使用DataSource连接SQLServer并获取数据。
实战2：Session Bean
建立一个简单的Bean：1．关闭所有工程：File->Close Projects2．选择File－>New project 在Name栏中输入HelloDemo，Directory栏中输入存放路径（不要有空格），其他不变，单击Finish。3．选择File－>New->Enterprise->EJB 2.0 Designer单击OK。在弹出的对话框中单击new建立一个Moudle，在Name中输入HelloMoudle单击OK关闭当前对话框，再次单击OK关闭对话框。4．在右侧的工作区中单击右键选择：Create EJB－>Session Bean，将Bean Name改为HelloBean5．右键单击代表HelloBean的长方形，选择Add->Method按如下填写：Method Name = SayHelloReturn Type = java.lang.StringInput parameter 不添Interface = remote6. 右键单击代表HelloBean的长方形，选择 View Bean Source按如下填写SayHello()：public java.lang.String SayHello(){/**@todo Complete this method*/return new String(“Hello World “);}7.按F9运行，在弹出的对话框中选择Run页，单击New，在configure name处填写Server Runtime Configuration，再选择Run－>Server，单击OK关闭当前对话框,单击OK开始编译运行。运行起来之后在左上角的目录树中右键单击HelloModule选择：Deploy options for “HelloModule.jar”->Deploy来发布Bean。建立客户端：1．选择File－>New->Enterprise->EJB Test Client单击OK。选中Genrate method for Default remote interface calls with default arguments单击OK。2．按如下填写main()：public static void main(String[] args){HelloBeanTestClient1 client = new HelloBeanTestClient1();// Use the client object to call one of the Home interface wrappers// above, to create a Remote interface reference to the bean. // If the return value is of the Remote interface type, you can use it// to access the remote interface methods. You can also just use the // client object to call the Remote interface wrappers.client.create();System.out.println(client.SayHello());} 选择Run－>Run “HelloBeanTestClient1.java” using defaults运行。实战3：Entity Bean
配置Weblogic for SQL Server JDBC Driver ：1. 选择：Tools->Enterprise Setup，单击Database Drivers页上的Add, 在弹出的对话框中单击New,. 在弹出的对话框中填写Name为WebLogic for SQL Server， Location选择User Home，单击Add按钮，选择weblogic.jar，例如：F:\bea\weblogic700\server\lib\weblogic.jar, 单击OK关闭当前对话框，可以看到WebLogic for SQL Server已被加入，单击OK关闭当前对话框，再次单击OK，配置完成。重起Jbuilder 7。建立一个简单的CMP Entity Bean ：1. 关闭所有工程：File->Close Projects2. 选择File－>New project 3. 在Name栏中输入CMPDemo，Directory栏中输入存放路径（不要有空格），其他不变，单击Finish。4. 选择File－>New->Enterprise->EJB Module单击OK。在弹出的对话框中，在Name中输入CMPMoudle, Version选择：EJB2.0 Compliant其余不变,单击OK关闭当前对话框。5. 右键单击屏幕左下角的DataSources，选择Import Schema From Database，在弹出的对话框中，按如下填写：选中 All Schemas和ViewsDriver选择weblogic.jdbc.mssqlserver4.DriverURL= jdbc:weblogic:mssqlserver4:northwind@localhost:1433UserName=saPassword=”” / /此处为sa密码JNDI Name= SQLServer单击OK，如果设置正缺的话，DataSources下将会出现名为SQLServer的Datasource6．单击名为SQLServer的Datasource左边的加号将其展开，将会看到所有的表和视图。7．右键单击Employees表，选择Create CMP 2.0 Entity Bean8．单击代表Employees表的长方形顶部的Employees，在右侧弹出的面板中将Interfaces选为local/remote，选择File->Save All保存全部项目。9．选择Project－>Make ”CMPModule”, 编译成功后，右键单击左上角的CMPModule选择Deploy Options for ”CMPModule.jar”－>Deploy，将其发布至Weblogic。建立客户端：1．选择File－>New->Enterprise->EJB Test Client单击OK。选中Genrate method for Default remote interface calls with default arguments单击OK。3．按如下填写main()：public static void main(String[] args){EmployeesTestClient1 client = new EmployeesTestClient1();client.findByPrimaryKey(new Integer(1));if (client.employeesRemote == null){System.out.println("Error in testRemoteCallsWithDefaultArguments(): " + ERROR_NULL_REMOTE);return ;}client.getEmployeeID();client.getLastName();client.getFirstName();client.getTitle();client.getTitleOfCourtesy();client.getBirthDate();client.getHireDate();client.getAddress();client.getCity();client.getRegion();client.getPostalCode();client.getCountry();client.getHomePhone();client.getExtension();client.getPhoto();client.getNotes();client.getReportsTo();client.getPhotoPath();}选择Run－>Run “EmployeesBeanTestClient1.java” using defaults运行。实战4：JMS
配置Weblogic1. 启动WebLogic72. 打开IE6，在地址栏中输入：<http://localhost:7001/console>3. 输入用户名和密码4. 在左边的目录树中选中Services->JMS->Connection Factories，单击右侧的Configure a new JMS Connection Factory ，输入以下信息：Configuration->General页：Name = MDBDemo Connection FactoryJNDIName= MDBDemoCF其它不变，单击Create建立Connection Factory。Targets->Server页：将myserver(服务器名称)移至右侧的列表中，但击单击Apply5. 在左边的目录树中选中Services->JMS->Stores，单击右侧的Configure a new JMSFileStore，输入以下信息：Configuration->General页：Name ＝ MDBDemo StoreDirectory: ＝ F:\bea\user_projects\mydomain\JMSStores （任意存在的目录即可）单击Create建立JMSFileStore。6. Services->JMS->Servers，单击右侧的Configure a new JMS Connection Factory ，输入以下信息：Configuration->General页：Name ＝ MDBDemo JMSServerStore ＝ MDBDemo Store其它不变，单击Create建立JMS Server。Targets->Servers页：Target ＝ myserver（你的weblogic server的名字）单击Configuration->General页中的Configure DestinationsName = MDBDemo TopicJNDIName= MDBDemo Topic其它不变，单击Create建立Destination。配置完毕。建立Message Driven Bean：1．关闭所有工程：File->Close Projects2．选择File－>New project 3．在Name栏中输入MDBDemo，Directory栏中输入存放路径（不要有空格），其他不变，单击Finish。4．选择File－>New->Enterprise->EJB Module单击OK。5．在弹出的对话框中，在Name中输入MDBMoudle, Version选择：EJB2.0 Compliant其余不变,单击OK关闭当前对话框。6．在右侧的EJB Designer 中单击鼠标右键选择：Create EJB－>Message－Driven Bean，按如下填写：Bean Name ＝ MDBDemoTransaction Type ＝ ContainerDestination Name ＝ MDBDemo TopicDestination Type ＝ javax.jms.Topic其它不变。7．Project－>Make ”MDBModule”, 编译成功后，右键单击左上角的MDBModule选择Deploy Options for ”MDBModule.jar”－>Deploy，将其发布至Weblogic。
建立客户端：以下是客户端源码，保存成TestClient.java加入工程后，选择Run－>Run “TestClient.java” using defaults运行即可，可以在weblogic console窗口看到输出。如果看不到输出，重起weblogic试一试。package mdbdemo;
