Abstract

Local transactions are supported by an application view instance that can switch from a stateless session bean to a stateful session bean in order to open a connection for a local transaction. The state that the stateful session bean holds is then the connection. The stateful session bean can hold the connection open across multiple requests in the local transaction for the duration of the transaction. A local transaction interface allows a user to manage the transaction in the application view, and to switch the application view between a stateless session bean and a stateful session bean. A local transaction interface can contain a local transaction management contract, which enables an application server to provide an infrastructure and run-time environment for management of the transaction.

This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Claims

1. A system for supporting a local transaction with an application view, comprising:

an application view capable of switching from a stateless session bean to a stateful session bean in order to open a connection for a local transaction, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

a local transaction interface allowing a user to manage the local transaction in the application view.

2. A system according to claim 1, further comprising:

a Common Client Interface class through which the local transaction interface can be exposed to a resource adapter client.

3. A system according to claim 1, wherein:

the application view maintains the connection open for the duration of the local transaction.

4. A system according to claim 1, wherein:

the local transaction interface further allows a user to switch the application view between a stateless session bean and a stateful session bean.

5. A system according to claim 1, wherein:

the application view is capable of opening a database connection for a local transaction.

6. A system according to claim 1, further comprising:

a transaction manager adapted to obtain a resource for any connection open for a local transaction.

7. A system according to claim 1, wherein:

the local transaction interface further contains a local transaction management contract.

8. A system according to claim 1, wherein:

the local transaction interface further contains a local transaction management contract adapted to enable an application server to provide an infrastructure and run-time environment for management of the transaction.

9. A system according to claim 1, further comprising:

a plug-in capable of performing a transaction method for the application view.

10. A system according to claim 1, further comprising:

a plug-in capable of creating a new instance of the application view.

11. A system according to claim 1, further comprising:

a plug-in capable of invoking a service within the local transaction.

12. A system according to claim 1, wherein:

the application view is capable of opening a connection for a local transaction against an Enterprise Information System.

13. A system according to claim 1, wherein:

the application view is capable of opening a connection for a local transaction against a resource adapter.

14. A method for supporting a local transaction with an application view, comprising:

opening a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

allowing a user to manage the local transaction in the application view through a local transaction interface.

15. A method according to claim 14, further comprising:

holding the connection open for the duration of the local transaction.

16. A method according to claim 14, further comprising:

exposing a local transaction interface to a resource adapter client.

17. A system for supporting a local transaction with an application view, comprising:

means for opening a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

means for allowing a user to manage the local transaction in the application view through a local transaction interface.

18. A computer-readable medium, comprising:

means for opening a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

means for allowing a user to manage the local transaction in the application view through a local transaction interface.

19. A computer program product for execution by a server computer for supporting a local transaction with an application view, comprising:

computer code for opening a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

computer code for allowing a user to manage the local transaction in the application view through a local transaction interface.

20. A computer system comprising:

a processor;

object code executed by said processor, said object code configured to;

open a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

allow a user to manage the local transaction in the application view through a local transaction interface.

21. A computer data signal embodied in a transmission medium, comprising:

a code segment including instructions to open a connection for a local transaction by switching an application view from a stateless session bean to a stateful session bean, the stateful session bean capable of holding the connection open across multiple requests in the local transaction; and

a code segment including instructions to allow a user to manage the local transaction in the application view through a local transaction interface.
