The standard mechanism to implement this is to wrap the functionality you - want to integrate in a class that implements the <emphasis> - <property moreinfo="none">ActionHandler</property> - </emphasis> interface. In order to demonstrate it let's specify Hello World action for our - process.</para> - - <section> - <title>Creating a Hello World Action</title> - - <para>Each Hello World process should integrate one or more Hello World actions, so this is - what we will be doing. We can integrate custom code at different points in the process - definition.

These events - are amongst others, going over a transition, leaving or entering nodes, after and before - signalling. </para> - - <para> To make things a little bit more concrete, let's create a new class called <emphasis> - <property moreinfo="none">HelloActionHandler</property>. - </emphasis> For that firstly we'll create a new package <emphasis> - <property moreinfo="none">com.jbay.action</property> - </emphasis> in the <emphasis> - <property moreinfo="none">src/java/main</property> - </emphasis> folder of our project.

Then we give the process a signal to move it to the auction state.
