首先，我們需要根據現有的開發環境對seam-gen進行配置：JBoss AS安裝目錄、Eclipse workspace及數據庫連接。這些都很容易，只要敲入：

cd jboss-seam-2.0.x
seam setup

根據彈出的提示輸入開發環境的相關信息:

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

該工具提供了相應的默認值，因此你可以直接按Enter鍵。

最重要的是你要對EAR部署還是WAR部署進行選擇。EAR項目支持EJB 3.0 并需要Java EE 5。而WAR包不支持EJB 3.0，但可在J2EE環境中部署。 另外WAR也更較簡單，便于理解。假若你已安裝了EJB3 profile，那你就用ear好了，否則，就只好用 war。 在此假設我們選擇了EAR部署，當然此教程也適用于WAR部署。

如果你手上有現成的數據模型，請確保你已輸入現有數據庫的表名。

這些設置保存在 seam-gen/build.properties 文件中，但你可通過運行 seam setup 來再次修改。

現在我們就可以在Eclipse workspace目錄中創建一個新的項目，只需輸入：

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>

這組操作復制了Seam jar文件及相應的jar文件與JDBC驅動jar到新建的Eclipse項目中，并生成了所需的源文件及其配置文件、一個模板文件和樣式文件，及相應的Eclipse元數據及Ant構建腳本。 只要你依此操作 New -> Project... -> General -> Project -> Next，輸入Project name （此例為helloworld），并接著點擊 Finish，就可將Eclipse項目自動部署到JBoss AS分解式的（exploded）目錄結構中，請不要在新項目向導中選擇 Java Project。

若Eclipse中的默認的JDK不是Java SE 5 或Java SE 6，你就得通過 Project -> Properties -> Java Compiler 來選擇與Java SE 5 兼容的JDK。

另外，可在Eclipse之外輸入 seam explode 來部署項目。

在 http://localhost:8080/helloworld 中查看此應用的首頁。 view/home.xhtml 是個使用 view/layout/template.xhtml 模板生成的Facelets 頁面，試著在Eclipse中編輯此頁面或該模板，并在瀏覽器中刷新頁面，立即看到結果。

別被在項目目錄中的如此多的XML配置文件給嚇暈了。那都是些標準的Java EE的東西，它們只需生成一次就不用再去理會了。 在所有的Seam項目中，90%的配置內容都是一樣的（這些可由seam-gen來幫我們完成）。

新生成的項目包含了三個數據庫及持久化配置文件。jboss-beans.xml、persistence-test.xml 及 import-test.sql 文件是用在當TestNG對HSQLDB進行單元測試時。 在 import-test.sql 中的數據庫Schema及其測試數據總是在測試前就已轉入數據庫中。 myproject-dev-ds.xml、persistence-dev.xml 及 import-dev.sql 文件是在部署應用到開發數據庫時使用的。 數據庫schema是否可在部署時自動導出，取決于你是否在設置seam-gen環境時配置了已存在的數據庫。 myproject-prod-ds.xml、persistence-prod.xml 及 import-prod.sql 文件是在部署應用到生產數據庫時使用的。在部署時數據庫schema并不自動導出。
