WAS supports all of the resources defined by the J2EE. 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.

 

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 IBM WAS applications to exchange messages asynchronously with other JMS clients by using JMS destinations (queues or topics).

 

Mail

JavaMail API, a code segment can be embedded in any J2EE 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.

 

URLs

J2EE applications can use URLs as resources in the same way other J2EE resources, such as JDBC and JavaMail, are used.

 

Resource environment entries

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