The href uniquely identifies the linked entity or attribute. Use this operation to get the values of a relationship. When the employee is read, the response will contain a relationship link pointing to the relationship between the employee and the phone entities, plus a list of the links, with each link pointing to a (unique) phone number that the employee owns. For base operations on the persistence unit, add the persistence unit name: For specific types of operations, add the type of operation, for example: Entity operations: /persistence/{version}/{unit-name}/entity, Query operations: /persistence/{version}/{unit-name}/query, Single result query operations: /persistence/{version}/{unit-name}/singleResultQuery, Persistence unit level metadata operations: /persistence/{version}/{unit-name}/metadata, For complete documentation on how to construct these URIs, see Section 20.4, "RESTful Data Services API Reference.". DELETE /persistence/{version}/{unit-name}/entity/{type}/{id}/{relationship}?{relationshipListItemId}. Jersey project at http://jersey.java.net/. With JAX-RS, you use annotations to define resources and the actions that can be performed on those resources. The mappedBy attribute must be on the inverse side. The Java SE 8 Professional Certification has two exams, OCAJP 8 or 1Z0-808 and OCPJP 8 or 1Z0-809, cost of both certification exams are different in different countries. Merge takes an object graph and makes it part of the persistence context through comparison. For example: POST /persistence/{version}/{unit-name}/query/{name};parameters?hints, POST http://localhost:8080/exampleApp/persistence/v1.0/ExamplePU/query/Foo.deleteAllByName;name=myname, POST http://localhost:8080/exampleApp/persistence/v1.0/ExamplePU/query/Foo.updateName;name=myname?eclipselink.jdbc.max-results=500, A payload containing the number of entities updated or deleted, GET /persistence/{version}/{unit-name}/singleResultQuery/{name};{parameters}? Composite keys are separated using the + character and should be specified in an order corresponding to the Java default sorting of the attribute names. Use RESTful Data Services to expose entities using a RESTful service, without writing JAX-RS code. Messages related to RESTful Data Services operations are logged to a logger called org.eclipse.persistence.jpars. For example, consider an entity Phone, with attributes extB=123 and extA=321. Most messages are logged at the FINE level. The following query operations are supported: Named queries doing reads can be run two ways in JPA. Add the toplink-dataservices-web.jar file to the WAR containing the application, under WEB-INF/lib. Not only is the price lower, but the quality of the questions is good as is the support. They are: GET /persistence/{version}/{unit-name}/query/{name};{parameters}? The answer to each question has given at end of this post. Java EE at a Glance. Typically this will occur if the metadata specifies a generated key and the field that contains that key is unpopulated. Messages related to operations within EntityManagers, EntityManagerFactorys and JAXBContexts are logged in the same manner as other EclipseLink logging. OK, with a payload containing a list of types, with links to more detailed metadata, for example: NOT_FOUND if the persistence unit is not found, GET /persistence/{version}/{unit-name}/metadata/query, GET http://localhost:8080/exampleApp/persistence/v1.0/ExamplePU/metadata/query. JSON responses use square brackets [] to encapsulate a collection and curly braces {} to encapsulate each member of a collection. It still only outputs 3 rows ! Passing By Reference". Learn more about the technologies that comprise the Java EE 8 platform using the specifications, and then apply them with the Java EE 8 SDK. So, it's probably acceptable to have the EJB stuff in there, even if In every industry, businesses face the challenge of accommodating ever greater demands for high-speed data access, diverse clients, and Both are supported in the REST API. The base URI for relationship operations is as follows: /persistence/{version}/{unit-name}/entity/{entity}/{id}/{relationship}. The way this is handled is as follows: JPA bidirectional relationships are defined to have an owning side and a non-owning side. Since JPA is from Sun/Oracle I doubt there will ever be an EJB-less, JPA-only certification. The following JSON passes myA by value: To pass an object by reference, use a _link. The relationshipListItemId is meaningful only when the {relationship} to be removed is a list. changes I make in oracle are not reflecting here. They also have a forum in which you can ask questions about the individual questions in the mock exam. The most complex aspect of using native SQL queries within JPA is binding results. Relationships are currently not supported for embedded attributes. http://wiki.eclipse.org/EclipseLink/Examples/REST/GettingStarted, http://www.oracle.com/technetwork/middleware/ias/index-099524.html, Section 20.4, "RESTful Data Services API Reference.
