CDI interceptorsĪre now more widely applicable to beans.
The platform a lot more cohesive and integrated. Is now a core component model, and is enabled by default. The Contexts and Dependency Injection (CDI) specification Out-of-the-box experience for new developers starting with the ManagedExecutorService-provide a seamless Operational environments, a preconfigured JMS ConnectionFactory forĪccessing a JMS provider, and a preconfigured Preconfigured DataSource for accessing databases in More defaults for the application’s use-such as a Without the Client API (introduced in JAX-RS 2), developersĪre required to use basic HttpUrlConnection APIs and Simplified message sending are further examples of features that the Finally, correct error handling, runtime exceptions instead ofĬhecked exceptions, method chaining on JMSProducer, and JMSContext provides the unified functionality ofĪddition, several JMS interfaces implementĪutocloseable and thus are automatically closed after JavaServer Faces (JSF) introduces pass-through attributes andĮlements that allow near-total control over the user experience ofĮach individual element in the view. To parse, generate, transform, and query JSON using a Streaming API Until now, developers were required to bundle third-party JSON is the lingua franca of the Web for lightweight dataĮxchange. Standard API to develop and deploy WebSocket clients and It provides a two-way, full-duplex communicationĬhannel between a client and a server over a single TCP
The WebSocket protocol, developed as part of theĬollection of technologies that make up HTML5, brings a new level ofĮase of development and network efficiency to modern, interactive The Java EE 7 platform built upon the previous version with three The previous versions of the platform, starting with Java EEĥ and continuing with Java EE 6, took the first steps in providing a Java EE 7 was released in June 2013 and provides a simple,Įasy-to-use, and complete stack for building such web and enterpriseĪpplications. Specification that also describes the API, javadocs, and expected runtime This container-based model and abstraction of resource accessĪllows the platform to offload the developer from common infrastructureĮach component of the platform is defined in a separate Transaction management, security checks, resource pooling, and state Inject the services required by the component, such as declarative Interposing a container between the applicationĬomponents and the Java EE services allows the container to transparently

TheseĬomponents are deployed in containers that provide runtime support.Ĭontainers provide a federated view of the underlying Java EE APIs to theĪpplication components. Injection, and resource management that span across the platform. Tier, and also provides some additional services such as naming,
The Java EE platform defines APIs for different components in each These applications should be responsive and capable of scaling to Multitier applications, with a frontend tier consisting of a webįramework, a middle tier providing security and transactions, and aīackend tier providing connectivity to a database or a legacy system. These applications are typically designed as The Java Platform, Enterprise Edition (Java EE), provides a standards-based platform for developing web andĮnterprise applications.
