"《WebSphere Application Server for Developers V7》开发指南详细介绍了如何在IBM WebSphere V7版本中进行开发和部署，重点涵盖了Enterprise JavaBeans (EJB) 和Java Message Service (JMS) 的应用。该指南由Michael Cheng、Sharon Tam和Shentong Wang共同编撰，旨在帮助开发者深入了解和实践WebSphere V7的功能与特性。书中首先引导读者安装和配置WebSphere Application Server，从基础设置开始，包括从IBM官方网站下载适用于V7.0版本的软件。在第一章“Setting up WebSphere Application Server”中，作者详细介绍了如何下载WebSphere应用程序服务器，以及安装过程中的关键步骤。这包括对不同环境（如Windows、Linux或Unix）的安装指导，确保读者能够在各自的平台上顺利启动开发工作。章节还会涵盖初始化配置，比如创建和管理应用程序服务器实例，配置必要的组件和服务。随着深入，第二部分会着重讲解如何利用EJB进行企业级应用的构建。EJB是Java EE的一部分，它提供了面向对象的编程模型来处理业务逻辑，通过服务端组件简化客户端与数据库的交互。读者将学习如何设计、实现和部署EJB组件，以及如何与WebSphere V7集成，以充分利用其容器管理的优势。第三部分聚焦于JMS在WebSphere V7中的应用，JMS是一种消息传递服务，用于在分布式系统中异步通信。开发者将了解到如何创建和管理消息队列，编写消费者和生产者应用程序，以及如何通过JMS API实现可靠的消息传递和事务处理。此外，本书还包含如何增强应用程序功能和性能，提供最佳实践和案例研究，帮助开发者提升开发效率和产品质量。书中还特别指出，所有内容都基于WebSphere V7.0 Release 0，因此读者需要确保他们使用的版本信息一致。最后，该指南附带了版权信息和使用限制，提醒用户在使用前阅读注意事项，并鼓励读者提供反馈，保持与IBM Redbooks的互动。《WebSphere Application Server for Developers V7》是一个全面且实用的工具，适合希望在IBM WebSphere环境中开展现代企业级应用开发的开发者使用。"

1.1 Downloading WebSphere Application Server for Developers

WebSphere Application Server for Developers is offered at no charge. You can obtain it online

by following these steps:

1. Go to the following URL, as shown in Figure 1-1:

http://www.ibm.com/developerworks/websphere/downloads/

Figure 1-1 WebSphere downloads

2. Click WebSphere Application Server for Developers V7.0.

3. Click Download now in the Download section.

4. Log in with your IBM ID and password if you have an IBM ID, or click Proceed without an

IBM ID.

5. Select WebSphere Application Server for Developers V7.0, and click Continue.

6. Complete all of the fields on the form on the next page, and click I confirm.

7. In Download using Download Director, select the .zip file, and click Download now. A

Download Director window opens, where the File attribute is the file path to which your

selected package is downloaded.

Note: Download Director requires a plug-in that you might not have, so alternatively,

you can choose the Download using HTTP tab, and click Download now next to the

.zip file.

Chapter 1. Setting up WebSphere Application Server 3

1.2 Installing WebSphere Application Server

The downloaded archive .zip file contains an executable file that launches the installer when

run. Use the following steps to install WebSphere Application Server:

1. Extract the downloaded package.

2. In the extracted package folder, navigate to the WAS folder.

3. Double-click Install.exe.

4. Follow the steps provided by the installation wizard. Note the following considerations:

– Although we are not using the sample applications that come with the product,

installing the sample applications might be useful for you to test the deployment of

various applications on your own later.

– You can change the default installation directory so that it is easier to navigate to it.

– You must create at least one profile to use WebSphere. You can create profiles through

the installation wizard, or later. We show you how to create the profile after the

installation, in case you want to create more than one profile later. So, choose None

when you reach the WebSphere Application Server Environment window to not create

the profile, and click Yes when prompted with a warning. We describe the various ways

to create profiles next.

1.3 Creating profiles

A profile is the set of files that defines a single WebSphere Application Server runtime

environment. You can configure multiple profiles on a single machine without having to

perform a complete installation every time. You can create an initial profile during installation.

To create a profile after installation or to create additional profiles, you can use either the

command-line or GUI method.

Each profile has a profile name and a profile path. Profile names are unique within a

WebSphere installation. The default path for a profile is in the

install_root/profiles/profile name directory.

1.4 Using the command line

Example 1-1 shows you how to create a profile using the command-line tool.

Example 1-1 Create a profile using the command line

install root\bin\manageprofiles.bat -create -templatePath

install_root\profileTemplates\default -profileName profile_name -cellName

cell_name -nodeName node_name -hostName hostname -enableAdminSecurity true

-adminUserName user_name -adminPassword password -

samplesPassword samples_password -defaultPorts

We define the parameters that are used in manageprofiles command that is shown in

Example 1-1:

create Creates the profile.

templatePath The path of the template that is used to create the new profile. For

our environment, always use the default template.

4 WebSphere Application Server for Developers V7

profileName The name of the profile.

cellName The name of the cell. In WebSphere, a

cell is a set of resources that

are managed together, such as applications and application servers.

nodeName The name of the node. In WebSphere, a node is a set of resources

that are managed together on the same machine.

hostName The name of the host machine.

enableAdminSecurity Enables administrative security. Valid values include true or false.

Always set this value to true to secure your application server.

adminUserName The user ID that is used for administrative security.

adminPassword The password for the administrative user ID.

samplesPassword The password to use for samples. You use this password to restrict

access to web application samples that are installed during the

installation of the application server. The corresponding user name

is samples.

defaultPorts Use default port numbers for the ports on which the application

server listens.

If you want to run the sample applications, you must specify a samples password when using

the manageprofiles command to create a profile with administrative security enabled.

Try the following command to create a new profile, using the real path of install_root for

your environment, and a user name and password of your choosing. We use this environment

later to deploy the sample applications.

Example 1-2 Command-line example to create a profile

manageprofiles.bat -create -templatePath C:\was\profileTemplates\default

-profileName dev -cellName devCell -nodeName devNode -hostName localhost

-enableAdminSecurity true -adminUserName <user> -adminPassword <password>

-samplesPassword <password> -defaultPorts

INSTCONFSUCCESS: Success: Profile dev now exists. Please consult C:\was7000\pro

files\dev\logs\AboutThisProfile.txt for more information about this profile.

1.5 Using the GUI

The GUI interface offers an approach to create a profile that prompts you for information at

each step. Use the following steps to create a profile with the Profile Management Tool:

1. Access the Profile Management Tool by going to Start  All Programs  IBM

WebSphere Application Server V7.0 

Profile Management  Tool, as shown in

Figure 1-2 on page 5.

Note: Alternatively, you can access the WebSphere Application Server install folder

and run the following .bat file:

install root/bin/profileManagement/pmt.bat
