Bernard Labno updated JBSEAM-3844:
----------------------------------

    Attachment: stacktrace.txt


Provided patch is wrong !!! I overlooked the fact that EntityManagerFactory component would be recreated on every page load, so no data will get into database. There is a need to check if it is connected to the right datasource instance (an open one). It is not enough to check with isOpen() method for it returns true and the stacktrace says "You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null." .
And I don't know how to get to the ManagedConnectionFactory. My workaround for now is to create copy of "explode" ant task but remove "datasource" task from depends attribute.

> When using war exploded deployment and invoke "explode" ant target to hot deploy components (even if there is no changes) I get this error : 
> Caused by: javax.resource.ResourceException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.
> As I've inspected the problem is that javax.persistence.EntityManagerFactory changes and org.jboss.seam.persistence.EntityManagerFactory does not get reinitiated on hot deployment.

> 2008-12-15 13:53:18,412 INFO  ConnectionFactoryBindingService - Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=seamcourseDatasource' to JNDI name 'java:seamcourseDatasource'
> I think that Initialization.redeploy method needs to be updated to reinitialize all EntityManagerFactory instances but I'm not sure and need confirmation from experienced seam dev.
