How can I select events from two different channels?

Question

Hi everybody, I have another question! :)
When processing events in config.xml, using a CQL sentence, Eclipse compiler doesn't allow me to select more than one event.
I paste here my app.context.xml and my config.xml:
app.context.xml:
<wlevs:event-type-repository>
<wlevs:event-type type-name="HorseEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.HorseEvent</wlevs:class>
</wlevs:event-type>
<wlevs:event-type type-name="GunmanEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.GunmanEvent</wlevs:class>
</wlevs:event-type>
</wlevs:event-type-repository>
<!-- Adapter can be created from a local class, without having to go through a adapter factory -->
<wlevs:adapter id="sevenhorsesAdapter" class="com.bea.wlevs.adapter.example.sevenhorses.SevenHorsesAdapter" >
<wlevs:instance-property name="messageHorse" value="I am the horse number: "/>
<wlevs:instance-property name="messageGunman" value="I am the gunman number: "/>
</wlevs:adapter>
<wlevs:channel id="horseInputChannel" event-type="HorseEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>
<wlevs:channel id="gunmanInputChannel" event-type="GunmanEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>
<!-- The default processor for OCEP 11.0.0.0 is CQL -->
<wlevs:processor id="sevenhorsesProcessor" />
<wlevs:channel id="horseOutputChannel" event-type="HorseEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
<wlevs:channel id="gunmanOutputChannel" event-type="GunmanEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
And here you are the two config.xml, I have tried two different ones and none of them runs.
The first one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel
        ]]>
</query>
<query id="gunmansRule">
<![CDATA[ select * from gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
As you can see, I use here TWO CQL sentences from the two channels that are defined in app.context.xml.
The other one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel, gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
I use here only ONE CQL sentence in which I try to get events from the two channels that are defined.
None of them works.
Can anybody help me?
Thank you!
