J2C Activation Specifications collection
This page contains a list of Java 2 Connector (J2C) activation specifications for a resource adapter configuration and is used to create new J2C activation specifications, to select J2C activation specifications for configuration changes, or to delete J2C activation specifications.
Activation specification definitions and classes are provided by a resource adapter when it is installed. Using this information, the administrator can create and configure J2C activation specifications with JNDI names that are then available for applications to use. The resource adapter uses a J2C activation specification to configure a specific endpoint instance. Each application configuring one or more endpoints must specify the resource adapter that sends messages to the endpoint. The application must use the activation specification to provide the configuration properties related to the processing of the inbound messages.
If we are using J2EE 1.4 and EJB 2.1 with WAS v6 or later, the decision on whether to use an activation specification or listener port depends on whether the JMS provider API is implemented with JCA. In J2EE 1.4, the JMS 1.1 API can be implemented with the JCA 1.5 API. If so, the MDB is a JMS MDB that is implemented as a connector MDB, and must therefore be configured with an activation specification. If not, this is the same JMS situation as for J2EE 1.3, and configure this EJB 2.1 MDB in the same way as you would configure an EJB 2.0 MDB, which in WebSphere Application Server is to use a listener port.
We can access this administrative console page in one of two ways:
- Resources > Resource Adapters > Resource adapters > resource_adapter > J2C activation specifications.
- Resources > Resource Adapters > J2C activation specifications.
