[jakartaee-platform-dev] Bean/Application Managed Resource

[hantsy bai <hantsy@xxxxxxxxx>]

Currently in Jakarta EE spec, almost all resources are container managed(have to register as a container resource firstly). An exception is bean managed or contained managed tx in EJB.

If possible to declare these resources as beans and available in the application lifecycle(like the Spring way). Esp, we could need a lightweight container such as an embedded server and packaged into Docker.

* DataSource

* EntityManagerFactory

* Local TransactionManager

* JMS Destination/Queue/Topic/ConnectionFactory

* ExecutorService

* MailSession

* Http Authentication Mechanism

```java

class Resources{

   @Produces

   @CustomerDB

   DataSource customerDataSource() {}

}

```
