Hello,
yes you are right, i have used the wrong wording. here is the correction
By now, for every targetsystem i do this:
1. edit jboss-bean.xml
2. package the app (run Ant build script)
3. copy the resulting war to the right system

But what i need is:
1. package the app (run Ant build script)
2. copy the war to all target systems
3. configure the right database into the app after deployment

define the datasource *after* the deployment.

Before using seam, i used a datasource provided by Tomcat.

i was used to specify my datasource in file context.xml in the META-INF Directory in my app.

So i can edit /conf/Catalina/localhost/baz.xml after deployment.
But now i am using the microcontainer and can not make any use of a tomcat provided datasource. Am i right?
Ciao,
Carsten

Hello Thomas,
so i have to use embeddable ejb?
At the moment i use seam managed sessions as introduced with the example 'hibernate' (the derivate from the hotel booking example)

If i use embeddablke EJB as suggested, how to inject the transaction manager into a datasource provided by Tomcat?

from jboss-beans.xml:
 <property name="transactionManager"><inject bean="TransactionManager"/></property>

If there is no easy solution for my environment i have and will live with the little inconvinience to package my app once for every database. (Concrete: I have to write an anttask for changing the attribute connectionUrl in jboss-beans.xml inside a war and than deploy this war to tomcat. )
Ciao,
Carsten
