26-707: EclipseLink is based on the TopLink product from which Oracle contributed the source code to create the EclipseLink project. The original contribution was from TopLink's 11g code base, and the entire code-base/feature set was contributed, with only EJB 2 Container-Managed Persistence (CMP) and some minor Oracle Application Server specific integration removed. This differs from the TopLink Essentials GlassFish contribution, which did not include some key enterprise features. The package names were changed and some of

52-445: A SOAP response (an XML-formatted document) with the resulting data, e.g., prices, location, features. Since the generated data comes in a standardized machine-parsable format, the requesting application can then integrate it directly. The SOAP architecture consists of several layers of specifications for: SOAP evolved as a successor of XML-RPC , though it borrows its transport and interaction neutrality from Web Service Addressing and

78-500: A more complex set of web services , based on WSDL , XSD and UDDI . These different services, especially UDDI, have proved to be of far less interest, but an appreciation of them gives a complete understanding of the expected role of SOAP compared to how web services have actually evolved. SOAP specification can be broadly defined to be consisting of the following three conceptual components: protocol concepts, encapsulation concepts and network concepts. The SOAP specification defines

104-544: A variety of data sources and formats such as Relational database , Object-relational database , Enterprise information system (EIS), XML and many others. Toplink was originally developed by The Object People in Smalltalk. It was ported to Java in 1996-1998 and called "TopLink for Java". In 2002, TopLink was acquired by Oracle Corporation and was developed under the Oracle Fusion Middleware product. The TopLink code

130-450: Is possible with the help of Object-XML, which is an EclipseLink component. By implementing JAXB , mapping information is provided through annotations. It also provides manipulation of XML. The Service Data Objects (SDO) provides with the use of SDO API, use dynamic objects to customize and manipulate XML, use of static data objects and conversion of XML Schema. Database Web Services (DBWS) facilitates access to relational databases with

156-473: Is provided by the EclipseLink Core. This API provides direct access to the runtime, which is embedded into the application. Persistence behavior is enabled by making application calls that invoke EclipseLink API to perform these functionalities which provides safe access to shared databases. Import the following class to use extended functionality of EclipseLink. The binding of Java classes to XML schemas

182-472: Is the same protocol as HTTP at the application level, but uses an encrypted transport protocol underneath) with either simple or mutual authentication; this is the advocated WS-I method to provide web service security as stated in the WS-I Basic Profile 1.1. This is a major advantage over other distributed protocols like GIOP/IIOP or DCOM , which are normally filtered by firewalls. SOAP over AMQP

208-496: Is used to add an instance and marks it for insertion into the database. On completion of the transaction, the newEmployee data will be inserted into the database. Updating an entity means simply reading the transaction and updating the properties of this entity. Updating the Employee LastName can be done as follows. Deleting an entity is the opposite of Insertion and can be one using remove(Object entity) method of

234-463: Is yet another possibility that some implementations support. SOAP also has an advantage over DCOM that it is unaffected by security rights configured on the machines that require knowledge of both transmitting and receiving nodes. This lets SOAP be loosely coupled in a way that is not possible with DCOM . There is also the SOAP-over-UDP OASIS standard. XML Information Set was chosen as

260-487: The EclipseLink project to be the reference implementation for JPA 2.0 ., Oracle did the same for JPA 2.1 and later JPA specifications. TopLink Oracle TopLink is a mapping and persistence framework for Java developers. TopLink is produced by Oracle and is a part of Oracle's OracleAS , WebLogic , and OC4J servers. It is an object-persistence and object-transformation framework. TopLink provides development tools and run-time functionalities that ease

286-773: The EntityManager. The EntityManager method flush() deletes the entity on completion of the transaction. Users can use most of the tools in the market and use TopLink along with it. But the following toots provide special integration with TopLink. SOAP SOAP is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks . It uses XML Information Set for its message format , and relies on application layer protocols, most often Hypertext Transfer Protocol (HTTP), although some legacy systems communicate over Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission. SOAP provides

312-462: The Messaging Protocol layer of a web services protocol stack for web services. It is an XML-based protocol consisting of three parts: SOAP has three major characteristics: As an example of what SOAP procedures can do, an application can send a SOAP request to a server that has web services enabled—such as a real-estate price database—with the parameters for a search. The server then returns

338-533: The application can store data on the Coherence grid called as JPA on the grid. TopLink Grid functionality can be used only if the user has license for Oracle Coherence. This functionality is provided by: To get support for TopLink Grid and EclipseLink, users also need to import the following package of classes. Database operations like Insert , Update and Delete can also be performed in TopLink. The changes made to

364-456: The code and configuration was moved around. The TopLink Mapping Workbench user interface has also been contributed to the project. EclipseLink is the intended path forward for persistence for Oracle and TopLink. It is intended that the next major release of Oracle TopLink will include EclipseLink as well as the next major release of Oracle Application Server. EclipseLink supports usage in an OSGi environment. Sun Microsystems has selected

390-500: The database are reflected in the Oracle Coherence cache. In Java Persistence API , an entity is a persistence class. Using TopLink, a number of performance features for writing large amounts of data can be implemented. Batch writing, stored procedure support, parameter binding, statement ordering and other features are offered to satisfy database constraints. The basic operations are The EntityManager method persist(Object entity)

416-461: The development process and help increase functionality. Persistent object-oriented data is stored in relational databases which helps build high-performance applications. Storing data in either XML (Extensible Markup Language) or relational databases is made possible by transforming it from object-oriented data. A rich user-interface is possible on TopLink with the help of TopLink Mapping Workbench. This Mapping Workbench makes it possible to carry out

442-474: The envelope/header/body from elsewhere (probably from WDDX ). SOAP was designed as an object-access protocol and released as XML-RPC in June 1998 as part of Frontier 5.1 by Dave Winer , Don Box , Bob Atkinson, and Mohsen Al-Ghosein for Microsoft , where Atkinson and Al-Ghosein were working. The specification was not made available until it was submitted to IETF 13 September 1999. According to Don Box, this

468-464: The following with ease. Oracle's JDeveloper IDE provides easy integration of these functionalities provided by the Mapping Workbench. With the use of TopLink , users can stay more focused on their primary cause and let TopLink handle the integration of persistence and object transformation into their application. Designing, implementing and deploying process is accelerated as TopLink supports

494-432: The help of web service. A database access can be made without the need to write a Java code. The XML SOAP Messages and the databases are connected by the runtime component of DBWS which uses EclipseLink. TopLink Grid is an integration mechanism that provides connection between Oracle Coherence and EclipseLink. An application generally interacts with the relational database, which is its primary database. But with TopLink

520-404: The messaging framework, which consists of: A SOAP message is an ordinary XML document containing the following elements: Both SMTP and HTTP are valid application layer protocols used as transport for SOAP, but HTTP has gained wider acceptance as it works well with today's internet infrastructure; specifically, HTTP works well with network firewalls . SOAP may also be used over HTTPS (which

546-425: The other hand, hardware appliances are available to accelerate processing of XML messages. Binary XML is also being explored as a means for streamlining the throughput requirements of XML. XML messages by their self-documenting nature usually have more 'overhead' (e.g., headers, nested tags, delimiters) than actual data in contrast to earlier protocols where the overhead was usually a relatively small percentage of

572-512: The overall message. In financial messaging SOAP was found to result in a 2–4 times larger message than previous protocols FIX (Financial Information Exchange) and CDR (Common Data Representation). XML Information Set does not have to be serialized in XML. For instance, CSV and JSON XML-infoset representations exist. There is also no need to specify a generic transformation framework. The concept of SOAP bindings allows for specific bindings for

598-549: The specification, however, became a W3C recommendation on June 24, 2003. SOAP originally stood for "Simple Object Access Protocol" but version 1.2 of the standard dropped this acronym. The SOAP specification was maintained by the XML Protocol Working Group of the World Wide Web Consortium until the group was closed 10 July 2009. After SOAP was first introduced, it became the underlying layer of

624-616: The standard message format because of its widespread use by major corporations and open source development efforts. Typically, XML Information Set is serialized as XML . A wide variety of freely available tools significantly eases the transition to a SOAP-based implementation. The somewhat lengthy syntax of XML can be both a benefit and a drawback. While it facilitates error detection and avoids interoperability problems such as byte-order ( endianness ), it can slow processing speed and can be cumbersome. For example, CORBA , GIOP , ICE , and DCOM use much shorter, binary message formats. On

650-625: Was donated to the Eclipse Foundation and the EclipseLink project was born in 2007. The EclipseLink now provides the functionality of TopLink. Sun Microsystems selected EclipseLink in March 2008, as the implementation for the JPA 2.0, JSR 317 reference. A number of versions of TopLink have been released since and the latest version 12c (12.1.3) is available for free Download. The runtime component of TopLink

676-485: Was due to politics within Microsoft. Because of Microsoft's hesitation, Dave Winer shipped XML-RPC in 1998. The submitted Internet Draft did not reach RFC status and is therefore not considered a "web standard" as such. Version 1.1 of the specification was published as a W3C Note on 8 May 2000. Since version 1.1 did not reach W3C Recommendation status, it can not be considered a "web standard" either. Version 1.2 of
