| Function | Jakarta RESTful Web Services support |
HTTP messaging |
Jakarta RESTful Web Services |
|---|---|---|---|
| Request and resource method mapping | B | A | A |
| Mapping of request and resource method | B | C [1] | A |
| Mapping of HTTP method | B | C [1] | A |
| Convert request/response according to the media type |
B | C [1] | A |
| Entity validation | A | A | A |
| Injection to resource class (Jakarta Contexts and Dependency Injection) |
C [2] | C [2] | A |
| Filter for request/response | C [3] | C [3] | A |
| Interceptor for reading and writing the body | C [4] | C [5] | A |
| Client API | C [6] | A | A |
| Asynchronous operation | C [7] | C [7] | A |
| Error log output | A | A | D |
| Checking the maximum capacity of the request body | C [8] | A | D |
| Output of the trace log | C [9] | A | D |
| Retransmission control | C [9] | A | D |
| Service availability check | C [10] | C [10] | D |
| Transaction control | C [11] | C [11] | D |
| Callback on business process errors | C [12] | A | D |
| [1] | (1, 2, 3) HTTP messaging is not designed in consideration of REST. Use Jakarta RESTful Web Services support for RESTful web services. |
| [2] | (1, 2) Jakarta Contexts and Dependency Injection is not available because Jakarta RESTful Web Services support and HTTP messaging run as Nablarch web applications. |
| [3] | (1, 2) Create a handler for creating a request/response filter. |
| [4] | Create a BodyConverter with Jakarta RESTful Web Services support for creating an interceptor to read and write the body. |
| [5] | Use data format of Nablarch to read and write the body. Create a DataRecordFormatter to change the data format. |
| [6] | If Jakarta RESTful Web Services client is needed, use a Jakarta RESTful Web Services implementation (such as Jersey or RESTEasy). |
| [7] | (1, 2) It is assumed that asynchronous operation in the server is not required. Support will be considered if there is a request. |
| [8] | Use the function to check the request size on the web server or application server. |
| [9] | (1, 2) Each application is assumed to have different requirements. Design/implement in the application. |
| [10] | (1, 2) If a service availability check in Nablarch matches the application’s requirements, use the check. If a check does not match, design/implement the check in the application. |
| [11] | (1, 2) Use the transaction management available in Nablarch. |
| [12] | Error handling is assumed to be common and JaxRsResponseHandler is assumed to be customized. To handle errors individually in business operations, use try/catch in resource methods. |
