+ <title>Deploying an application created using
+ <literal>seam-gen</literal> on Websphere 6.1.0.13</title>
+
+ <para><literal>seam-gen</literal> is a very useful tool for developers
+ to quickly get an application up and running, and provides a foundation
+ to add your own functionality. Out of box <literal>seam-gen</literal>
+ will produce applications configured to run on JBoss AS. These
+ instructions will show the steps needed to get it to run on Websphere.
+ As stated above in <xref linkend="jee5-websphere-section"/> there
+ are some tricky changes needed to get an EJB3 application running. This
+ section will take you through the exact steps.</para>
+
+ <para>The first step is setting up <literal>seam-gen</literal> to
+ construct the base project. There are several choices made below,
+ specifically the datasource and hibernate values that we will adjust
+ once the project is created.</para>
