J2SE 5.0 stayed J2SE 5.0 J2SE 6.0 is called Java SE 6 J2EE 5.0 became Java EE 5 J2ME will become Java ME
اسلاید 4: v100830Intro to JavaEE4Java EE Architecture
اسلاید 5: v100830Intro to JavaEE5Java EE ArchitectureDoes not imply physical partitioning into machines, processes, etc.No “all or nothing” requirementuse what you need
اسلاید 6: v100830Intro to JavaEE6ContainersProvide Java EE runtime environments with J2SE v5.0Provide required services to application componentsexample services: JMS, JTAapplication components: Applets, Java applications, Servlets/JSPs, and EJBsUnderstand application component deployment formatsInterposes between application components to transparently inject services requiredtransactions, security checks, resource poolingSynonymous with application server from the application developer point of view
اسلاید 7: v100830Intro to JavaEE7Application ComponentsApplication ClientJava programs that execute outside of the EJB, Web, and Applet ContainersTypically GUI-basedAppletsGUI componentstypically execute in Web browserWeb Applicationsaccessed through HTTPprimarily generate HTML and XML outputServlets, JSPs, JSF, etc.Enterprise Java Beans (EJB) execute in managed environment that include transactionstypically provide business logic for Java EE application
اسلاید 8: v100830Intro to JavaEE8Resource AdaptersSystem-level software componentExtends functionality of ContainerProvides connectivity with external resource managers or native language componentsImplement existing (e.g., JDBC, JMS) or alternate APIsPlugin into Java EE environment to provide system-level support forResource PoolingTransactionsSecurity
اسلاید 9: v100830Intro to JavaEE9Standard ServicesCommunications ServicesHTTPJ2SE java.net package defines client-side APIJava EE defines server-side API defined within servlet, JSP, JSF, and Web service interfacesHTTPSuse of HTTP over SSL for transport level securityJava Message Service (JMS)API for messagingsupport for publish-subscribe and point-to-point
اسلاید 10: v100830Intro to JavaEE10CORBA Support ServicesRMI-IIOPAPIs (javax.rmi) to allow RMI-style programming independent of underlying protocolJ2SE native RMI Protocol (JRMP)CORBA IIOP protocolPermit Java EE application components to access CORBA services compatible with RMI programming restrictionsPermit CORBA clients to access EJB componentsUsing dependency injection versus JNDI lookup eliminates the need for applications to use most of APIJava IDLPermit Java EE application components to invoke CORBA services, independent of the RMI API
اسلاید 11: v100830Intro to JavaEE11Coordination ServicesJava Naming and Directory Interface (JNDI)API for naming and directory accessJava Transaction API (JTA)application-level API to demarcate transaction boundariesprovider-level API between transaction and resource managers
