That won't work... here's what you should do.

First, you'll probably find it more convenient to put both the jta and  
non-jta datasources in one plan.   Lets say the id is then  
com.twcable.db/oracle/1.0/car. You'll have a dependency on that in  
your openejb-jar.xml plan similar to the existing dependencies.  This  
is the "primary" datasource plugin.

Now write another plan for another set of jta and nonjta datasources,  
say with id com.twcable.db/firebird/1.0/car.  Make sure the datasource  
names are exactly the same as in the primary plan.  All the config  
properties, pooling, etc, can be different but the names have to be  
the same.

Deploy the second plan.

To get your app to use the 2nd plugin instead of the primary plugin,  
you need a couple lines in the var/config/artifact-aliases.properties  
file.

com.twcable.db/oracle/1.0/car=com.twcable.db/firebird/1.0/car
com.twcable.db/oracle//car=com.twcable.db/firebird/1.0/car

You probably only need the second line.

Do you get errors? Does something not work?  The only bit I see that  
looks like it might be a problem is that the db pool dependencies need  
the type, hopefully also "car".

hope this helps
