Mail, URLs, and other J2EE resources

This topic describes the supported resources that are defined by Java™ Platform, Enterprise Edition (Java EE).

The product supports all of the resources defined by the Java EE. It adds the following resources in support of service extensions:

Data access (JDBC and J2C)

The J2EE Connector architecture defines a standard architecture that enables the integration of various enterprise information systems (EIS) with application servers and enterprise applications. It defines a standard resource adapter used by a Java application to connect to an EIS. This resource adapter can plug into the application server and, through the Common Client Interface (CCI), provide connectivity between the EIS, the application server, and the enterprise application.

For more information, refer to 数据访问资源.

Messaging

The product supports asynchronous messaging as a method of communication based on the Java Message Service (JMS) programming interface. The base JMS support enables the product applications to exchange messages asynchronously with other JMS clients by using JMS destinations (queues or topics).

For more information, refer to 消息传递资源.

Mail

Using JavaMail API, a code segment can be embedded in any Java EE application component, such as an EJB or a servlet, allowing the application to send a message and save a copy of the mail to the Sent folder.

For more information, refer to JavaMail API.

URLs

Java EE applications can use URLs as resources in the same way other Java EE resources, such as JDBC and JavaMail, are used.

For more information, refer to URL.

Resource environment entries

A resource environment reference maps a logical name used by the client application to the physical name of an object.

For more information, see 配置新的资源环境条目以便将逻辑环境资源名称映射到物理名称.
