Abstract

Systems, methods, and computer program products are provided for adapting service entities using a declarative approach in a service framework. In accordance with one implementation, a method is provided for adapting service entities. The method includes the steps of retrieving at least one software entity from a first repository in response to a first input and receiving a declaration from a user for adapting the software entity. The method further includes the steps of adapting the software entity to an adapted software entity based on the declaration and storing the adapted software entity in a second repository.

Claims

1. A computer program product for adapting software entities using a declarative approach in a service framework, the computer program product comprising a computer-readable storage medium having computer-readable program code stored therein, and the computer-readable program code being executable by a processor and comprising:

an entity retrieval instruction set executable to retrieve at least one software entity, in response to a first input, from a first repository;

a declaration instruction set executable to receive a declaration from a user for adapting the software entity;

an adapter instruction set executable to adapt the software entity to an adapted software entity based on the declaration; and

a storage instruction set executable to store the adapted software entity in a second repository.

2. The computer program product of claim 1, wherein the adapter instruction set further comprises:

a loader instruction set executable to load one or more pre-defined adaptation operations; and

a operation selector instruction set executable to select an adaptation operation, in response to a second input from the user, from the pre-defined adaptation operations, wherein the adapter instruction set is executable to adapt, based on the declaration and the selected adaptation operation, the software entity to the adapted software entity.

3. The computer program product of claim 2, wherein the entity retrieval instruction set further comprises:

an index retrieval instruction set executable to retrieve an index of software entities from the first repository; and

an index provider instruction set executable to provide the index to the user.

4. The computer program product of claim 2, wherein the adapter instruction set adapts the software entity to the adapted software entity without modifying the software entity.

5. The computer program product of claim 4, wherein the adapted software entity provides an adapted access interface similar to an access interface of the existing software entity.

6. The computer program product of claim 4, wherein one or more modifications to the software entity are propagated to the adapted software entity.

7. The computer program product of claim 2, further comprising:

an instantiation instruction set executable to instantiate an object based on the adapted software entity.

8. A method for adapting software entities using a declarative approach in a service framework, the method comprising:

retrieving at least one software entity, in response to a first input, from a first repository;

receiving a declaration from a user for adapting the software entity;

adapting the software entity to an adapted software entity based on the declaration; and

storing the adapted software entity in a second repository.

9. The method of claim 8, wherein adapting the software entity further comprises:

loading one or more pre-defined adaptation operations;

selecting an adaptation operation, in response to a second input from the user, from the pre-defined adaptation operations; and

adapting, based on the declaration and the selected adaptation operation, the software entity to the adapted software entity.

10. The method of claim 9, wherein selecting at least one software entity further comprises:

retrieving an index of software entities from the first repository; and

providing the index to the user.

11. The method of claim 9, wherein adapting the software entity further comprises:

adapting the software entity to the adapted software entity without modifying the software entity.

12. The method of claim 11, wherein the adapted software entity provides an adapted access interface similar to an access interface of the existing software entity.

13. The method of claim 11, wherein one or more modifications to the software entity are propagated to the adapted software entity.

14. The method of claim 9, wherein receiving a declaration further comprises:

verifying validity and syntactical correctness of the declaration.

15. The method of claim 9, further comprising:

instantiating an object based on the adapted software entity.

16. An system for adapting software entities using a declarative approach in a service framework, comprising:

a memory; and

a processor,

wherein the processor and the memory are configured to perform a method comprising;

retrieving at least one software entity, in response to a first input, from a first repository;

receiving a declaration from a user for adapting the software entity;

adapting the software entity to an adapted software entity based on the declaration; and

storing the adapted software entity in a second repository.

17. The system of claim 16, wherein adapting the software entity further comprises:

loading one or more pre-defined adaptation operations;

selecting an adaptation operation, in response to a second input from the user, from the pre-defined adaptation operations; and

adapting, based on the declaration and the selected adaptation operation, the software entity to the adapted software entity.

18. The system of claim 17, wherein adapting the software entity further comprises:

adapting the software entity to the adapted software entity without modifying the software entity.

19. The system of claim 18, wherein the adapted software entity provides an adapted access interface similar to an access interface of the existing software entity.

20. The system of claim 18, wherein one or more modifications to the software entity are propagated to the adapted software entity.
