<title>Running the examples on JBoss AS</title>
- <para> First, make sure you have Ant correctly installed, with <literal>$ANT_HOME</literal> and
- <literal>$JAVA_HOME</literal> set correctly. Next, make sure you set the location of your JBoss AS
- 4.2 installation in the <literal>build.properties</literal> file in the root folder of your Seam
- installation. If you haven't already done so, start JBoss AS now by typing <literal>bin/run.sh</literal>
- or <literal>bin/run.bat</literal> in the root directory of your JBoss installation. </para>
+ <para>The examples are configured for use on JBoss 4.2. You'll need to set <literal>jboss.home</literal>,

- <para> Now, build and deploy the example by typing <literal>ant deploy</literal> in the

+ <para> Once you've done that and started the application server, you can build
+ and deploy any example by typing <literal>ant deploy</literal> in the
+ the directory for that example. The examples all deploy to a URL
+ like <literal>/seam-<replaceable>example</replaceable></literal>.

<title>Running the examples on Tomcat</title>
- <para>
- First, make sure you have Ant correctly installed, with <literal>$ANT_HOME</literal> and
- <literal>$JAVA_HOME</literal> set correctly. Next, make sure you set the location of your Tomcat
- 6.0 installation in the <literal>build.properties</literal> file in the root folder of your Seam
- installation. You will need to follow the instructions in <xref linkend="config.install.embedded"/>
- for installing JBoss Embedded on Tomcat 6.0. JBoss Embedded is required to run the Seam demo
- applications on Tomcat. (However, it is possible to use Seam on Tomcat without JBoss Embedded.)
+ <para>The examples are also configured for use on Tomcat 6.0. You will need to follow the
+ instructions in <xref linkend="config.install.embedded"/>
+ for installing JBoss Embedded on Tomcat 6.0. JBoss Embedded is only required to run the Seam
+ demos that use EJB3 components on Tomcat. There are also examples of non-EJB3 applications that

- Now, build and deploy the example by typing <literal>ant tomcat.deploy</literal> in the
