i have found the failure. The SMPC Scope-Type ist Conversational, but i'am using Scope-Type SESSION for my Session Beans. If i switch to Conversational Scope-Type , then it works. Hope the Applications Behaviour will be achieved..

What value did you provide for unitName? Was it a value from your persistence.xml file? persistence-unit name=someDB | ... | /persistence-unit @PersistenceContext(unitName=someDB) I think this is the way it's done anyway. Personally, I use SMPC.

An SMPC is equivalent to an extended persistence context for conversationally scoped components.

i have more than one persistence unit defined in persistence.xml, because i'am using more than one database.

is there a way to define the extension of the persistence contexts directly in the persistence.xml instead of annotating this behaviour at the entitymanager definition?

i used SMPC(for example): core:managed-persistence-context name=myManagername | auto-create=true | persistence-unit-jndi-name=java:/myjndiname | /core:managed-persistence-context but the context is not extended, because in the code i get the ref to the Entitymanger i described further, but the Dataselection Model will not work in my stateful session beans, so it's not extended.

the problem is that the name of the entitymanager will be determined at runtime. so i can't put the static variable name before runtime in my code.

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
yes. look at my first posting ;) but if i inititialize the Entitymanager on that way(in some SFSB) the DataSelection Model will not work properly. It works only if in Annotate the Entitymanager Variable with @PersistenceContext(unit-namemyunitname, type=PersistenceContextType.EXTENDED). But then i must hardcode a unit-name, and thats the problem.

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
it's needed at runtime, because, every EntityManager has a binding to a database and which Database will be used, is decided at runtime.

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
You can't inject something if you don't know the name. If you have to
determine the name at runtime, you'll have to do it inline.
core:managed-persistence-context name=myManagername auto-create=true
persistence-unit-jndi-name=java:/myjndiname
| /core:managed-persistence-context
public void someMethod(){
| String emName = getEMName();
| EntityManager em = (EntityManager)Component.getInstance(emName, true);
| ...
| //do some work
| }

hmm, i define the Entitymanager on that way: EntityManager em = (EntityManager)Component.getInstance(someRuntimeString); Without the second Parameter set on true. maybe thats the problem ?

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
Actually, if auto-create=true, you don't need the true parameter, but getEMName() would return the String myManagername or any other EM name you have configured in components.xml.

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
yes. thats exact what i'am doing, but with more than on EntityManager defined in the corresponding xml files, and it works. Thats not the problem. The Problem that the Persistence context seems not to be extended. I get some data sets over the EntityManager, show them in a datatable, use Dataselection Model, but i don't get the correct reference to the selected data set in the table.

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
I really doubt your datamodelselection has anything to do with whether the persistence context is extended or not. Why don't you actually post your code and the problem you have rather than plucking solutions out of thin air?

[jboss-user] [JBoss Seam] - Re: How to Extend Persistence Context Programatically
but if i extend the context with @PersistenceContext(... type=PersistenceContextType.EXTENDED) Annotation, the Dataselectionmodel works :) So i think, its because the Context is not extend, if i do it the other way. Anyway, i will post my code tomorrow. It would be very nice if i can get a Solution.
