Below is an example of how we use SCXML. You can declare the event in the
<send> tag and it is sent. Of course each implementation of the executor
varies, but maybe this will help.
=====
<state id="state_logoff" final="true">
<transition event="menu" >
<send target="http://localhost:8080/goomzee"; targettype="client"
event="menu" delay="0" hints="" sendid="2345">
<vxml version="2.0">
<form>
<field name="input">
<prompt>You are now logged off. Goodbye</prompt>
</field>
<filled namelist="input">
<submit next="http://localhost:8080/goomzee/Voice"; namelist="input"/>
</filled>
</form>
</vxml>
</send>
<target next="state_welcome" />
</transition>
</state>
=====
You could alternately not include body content within sent and declare the
event as such:
<send target="http://localhost:8080/goomzee"; targettype="client"
event="menu" delay="0" hints="" sendid="2345" />
For this demo script, I have a welcome state which prompts for login/logoff.
Then a login state and a logoff state that ultimately reverts back to
welcome.
