首先，我们需要根据现有的开发环境对seam-gen进行配置：JBoss AS安装目录、Eclipse workspace及数据库连接。这些都很容易，只要敲入：

cd jboss-seam-2.0.x
seam setup

根据弹出的提示输入开发环境的相关信息:

C:\Projects\jboss-seam>seam setup
Buildfile: build.xml
setup:
[echo] Welcome to seam-gen :-)
[input] Enter your Java project workspace [C:/Projects]
[input] Enter your JBoss home directory [C:/Program Files/jboss-4.2.0.GA]
[input] Enter the project name [myproject]
helloworld
[input] Is this project deployed as an EAR (with EJB components) or a WAR (with no EJB support) [ear] (ear,war,)
[input] Enter the Java package name for your session beans [com.mydomain.helloworld]
org.jboss.helloworld
[input] Enter the Java package name for your entity beans [org.jboss.helloworld]
[input] Enter the Java package name for your test cases [org.jboss.helloworld.test]
[input] What kind of database are you using? [hsql] (hsql,mysql,oracle,postgres,mssql,db2,sybase,)
mysql
[input] Enter the Hibernate dialect for your database [org.hibernate.dialect.MySQLDialect]
[input] Enter the filesystem path to the JDBC driver jar [lib/hsqldb.jar]
../../mysql-connector.jar
[input] Enter JDBC driver class for your database [com.mysql.jdbc.Driver]
[input] Enter the JDBC URL for your database [jdbc:mysql:///test]
[input] Enter database username [sa]
gavin
[input] Enter database password []
[input] skipping input as property hibernate.default_schema.new has already been set.
[input] Enter the database catalog name (it is OK to leave this blank) []
[input] Are you working with tables that already exist in the database? [n] (y,n,)
y
[input] Do you want to drop and recreate the database tables and data in import.sql each time you deploy? [n] (y,n,)
n
[propertyfile] Creating new property file: C:\Projects\jboss-seam\seam-gen\build.properties

[echo] Type 'seam new-project' to create the new project

该工具提供了相应的默认值，因此你可以直接按Enter键。

最重要的是你要对EAR部署还是WAR部署进行选择。EAR项目支持EJB 3.0 并需要Java EE 5。而WAR包不支持EJB 3.0，但可在J2EE环境中部署。 另外WAR也更较简单，便于理解。假若你已安装了EJB3 profile，那你就用ear好了，否则，就只好用 war。 在此假设我们选择了EAR部署，当然此教程也适用于WAR部署。

如果你手上有现成的数据模型，请确保你已输入现有数据库的表名。

这些设置保存在 seam-gen/build.properties 文件中，但你可通过运行 seam setup 来再次修改。

现在我们就可以在Eclipse workspace目录中创建一个新的项目，只需输入：

seam new-project

C:\Projects\jboss-seam>seam new-project
Buildfile: build.xml
validate-workspace:
validate-project:
copy-lib:
[echo] Copying project jars ...
[copy] Copying 58 files to C:\Projects\helloworld\lib
[copy] Copying 9 files to C:\Projects\helloworld\embedded-ejb
file-copy-war:
file-copy-ear:
[echo] Copying resources needed for EAR deployment to the C:\Projects\helloworld/resources directory...
new-project:
[echo] A new Seam project named 'helloworld' was created in the C:\Projects directory
[echo] Type 'seam explode' and go to http://localhost:8080/helloworld
[echo] Eclipse Users: Add the project into Eclipse using File > New > Project and select General > Project (not Java Project)
[echo] NetBeans Users: Open the project in NetBeans
BUILD SUCCESSFUL
Total time: 7 seconds
C:\Projects\jboss-seam>

这组操作复制了Seam jar文件及相应的jar文件与JDBC驱动jar到新建的Eclipse项目中，并生成了所需的源文件及其配置文件、一个模板文件和样式文件，及相应的Eclipse元数据及Ant构建脚本。 只要你依此操作 New -> Project... -> General -> Project -> Next，输入Project name （此例为helloworld），并接着点击 Finish，就可将Eclipse项目自动部署到JBoss AS分解式的（exploded）目录结构中，请不要在新项目向导中选择 Java Project。

若Eclipse中的默认的JDK不是Java SE 5 或Java SE 6，你就得通过 Project -> Properties -> Java Compiler 来选择与Java SE 5 兼容的JDK。

另外，可在Eclipse之外输入 seam explode 来部署项目。

在 http://localhost:8080/helloworld 中查看此应用的首页。 view/home.xhtml 是个使用 view/layout/template.xhtml 模板生成的Facelets 页面，试着在Eclipse中编辑此页面或该模板，并在浏览器中刷新页面，立即看到结果。

别被在项目目录中的如此多的XML配置文件给吓晕了。那都是些标准的Java EE的东西，它们只需生成一次就不用再去理会了。 在所有的Seam项目中，90%的配置内容都是一样的（这些可由seam-gen来帮我们完成）。

新生成的项目包含了三个数据库及持久化配置文件。jboss-beans.xml、persistence-test.xml 及 import-test.sql 文件是用在当TestNG对HSQLDB进行单元测试时。 在 import-test.sql 中的数据库Schema及其测试数据总是在测试前就已转入数据库中。 myproject-dev-ds.xml、persistence-dev.xml 及 import-dev.sql 文件是在部署应用到开发数据库时使用的。 数据库schema是否可在部署时自动导出，取决于你是否在设置seam-gen环境时配置了已存在的数据库。 myproject-prod-ds.xml、persistence-prod.xml 及 import-prod.sql 文件是在部署应用到生产数据库时使用的。在部署时数据库schema并不自动导出。
