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.
In my persistence.xml, the data sources are IVRFrameworkXA and
IVRFramework.
The DB Pools are OracleXA and Oracle. What's wrong with the
deployement
plan?
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

Thanks for your help.
