内容简介:
1。连接MS sql SERVER2000
2。Session Bean
3。Entity Bean
4。JMS+Message-Driven bean
5。JSP调用EJB(待续)

全部实战内容都经过严格测试,决无问题,只需严格按照文中步骤即可!

配置webLOGIC

1.  启动WebLogic7

2.  打开IE6,在地址栏中输入:

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 Factory

JNDIName= 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Apply

5.  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 Store

Directory: = F:beauser_projectsmydomainJMSStores (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 JMSServer

Store = 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 Destinations

Name = MDBDemo Topic

JNDIName= 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 Projects

2. 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 = MDBDemo

Transaction Type = Container

Destination Name = MDBDemo Topic

Destination 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。
